How construction-to-permanent financing works
One loan that builds the house and then becomes your mortgage
An FHA One-Time Close Construction Loan finances the land, the construction of the home, and your permanent mortgage in a single loan with one closing — and that closing happens before construction begins.
You qualify once. You sign once. You pay one set of closing costs. When the house is finished and the local jurisdiction issues the Certificate of Occupancy, the construction loan converts into your long-term FHA mortgage automatically. There is no second application and no second closing.
The minimum required investment is 3.5% of the project, and if you already own the lot, land equity can count toward it — often covering it entirely.
It is also called FHA OTC, FHA single-close, or FHA construction-to-permanent financing. All the same product.
You will also see this called a construction-to-permanent loan, which describes it more literally: a loan that starts as construction financing and ends as a permanent mortgage without you having to do anything to make the switch happen.
If you want the fundamentals of FHA financing first — credit standards, mortgage insurance, how the 3.5% works — our Maryland FHA loans guide covers them. This page is about building rather than buying.
Why “one-time close” is the whole point
The name sounds like a convenience feature. It is actually a risk feature, and that is the part worth understanding.
In the traditional arrangement, you take a short-term construction loan, build the house, and then get a separate permanent mortgage to pay off the construction loan. Two loans. Two applications. Two underwriting reviews. Two closings. Two sets of costs.
The risk most buyers never think about
With two separate loans, you have to qualify again after the house is built — typically nine to twelve months later, sometimes longer.
If your income changed, if you switched jobs, if your credit moved, if rates rose, or if the lender’s guidelines tightened in the meantime, you may not qualify for the permanent loan. The house is built. The construction loan is coming due. And you are re-applying from a weaker position.
A one-time close removes that scenario entirely. You are already approved. Construction proceeding does not depend on you qualifying a second time.
The second structural advantage is rate certainty: your permanent rate is established at that single closing, before the first foundation pour, rather than being whatever the market offers you a year later.
One-Time Close vs Two-Time Close
| Feature | One-Time Close | Two-Time Close |
|---|---|---|
| Closings | One, before construction starts | Two — construction, then permanent |
| Qualification events | One | Two — you must qualify again after the build |
| Sets of closing costs | One | Two |
| Permanent rate established | Before construction begins | After construction finishes, at market |
| Risk if your circumstances change mid-build | Already approved | May fail to qualify for the permanent loan |
| Complexity for the borrower | Front-loaded, then largely hands-off | Spread across two transactions |
| Lender flexibility | Committed to one lender for both phases | Free to shop the permanent loan later |
The honest trade-off is the last row. A two-time close lets you shop the permanent mortgage when the house is done. That flexibility is real — and so is the risk that comes with it. Which matters more depends on how stable your income and credit are, and on your appetite for rate uncertainty over a build cycle.
FHA One-Time Close vs FHA 203(k)
These are not variations of each other
FHA One-Time Close is for ground-up new construction. There is no house yet. You are financing land, a build, and the mortgage that follows.
FHA 203(k) is for renovating a house that already exists. You are buying or refinancing a standing home and financing repairs to it.
If the structure exists and you are improving it, that is a 203(k). If you are putting a new home on a lot, that is One-Time Close. Choosing the wrong one wastes weeks, because the two products have entirely different appraisal, contractor and draw mechanics.
What the loan actually pays for
- The land — either purchased as part of the transaction, or credited as equity if you already own it
- Construction of the home, released to the builder in draws as work is completed
- The permanent mortgage that the loan becomes at completion
- Closing costs, where they can be included in the project total and the result still fits inside the FHA county loan limit
- Interest accruing during construction, on programs that provide for it — which is what allows a borrower to avoid mortgage payments while the home is being built
That last point varies by program rather than being a universal FHA guarantee, and it is worth confirming rather than assuming. Where it applies, you are not paying a mortgage and rent simultaneously through the build.
Land, land equity and the down payment
The minimum required investment is 3.5%, calculated on the total project rather than on a purchase price. HUD’s construction-to-permanent guidance is explicit that a borrower building on their own land must have made the required 3.5% cash investment or its equivalent in land equity.
That single rule is the most valuable feature of this loan for a great many Maryland buyers.
If you already own the lot
Take a $450,000 total project. The 3.5% minimum investment is $15,750.
A buyer who already owns a lot appraised at $90,000 has land equity far exceeding that requirement. The minimum investment is satisfied by the land, and the remaining cash needed at closing can be very small.
This is an arithmetic illustration, not a quote. Your actual figures depend on the appraisal, the final project cost, the county loan limit and full underwriting.
If you do not already own land, the purchase of the lot can be financed as part of the same transaction — which is precisely what removes the usual chicken-and-egg problem of needing to own land before anyone will lend you money to build on it.
Gift funds are permitted under FHA’s standard gift rules, and FHA’s interested party contribution limit of 6% applies to seller and builder contributions toward closing costs and prepaid items.
Before you buy the lot — the FHA angle
Buyers commonly buy land first and arrange financing second. That order creates the risk, because FHA approval does not make a lot buildable and a seller’s description of a “building lot” is not a finding by anyone with authority.
Two sets of questions decide whether your project works, and they are separate.
The site questions are answered locally: septic and percolation approval, water supply, permits, Critical Area review where the parcel is near tidal water, and flood zone. None of those involve FHA at all, and a lot can fail them regardless of how strong your loan approval is. Our Maryland construction loans guide walks through each one and who to ask.
The FHA questions are the ones this page answers:
- What you qualify to borrow, before you commit to a lot price
- The total project budget — land, construction and financed closing costs together
- The FHA loan limit in that specific county, which caps the whole project
- Whether the completed home is likely to appraise for what the project costs
- Whether your builder will satisfy both FHA and your lender
- If you already own or are buying the land outright, what its equity does to your down payment and your mortgage insurance
The sequence that protects you is: get approved, price the project, confirm the county limit, then commit to land with contingencies for septic and permits.
How the construction phase works
Once you close, the construction funds are held and released to your builder in draws as the project reaches verified milestones. You do not receive the money and you do not pay the builder directly. An inspection confirms the work before each release.
Practically, that means construction money is never handed to you. The lender releases advances against work that has actually been completed, each release supported by an inspection and the documentation the lender requires, and the builder is paid from those advances. Changes you make mid-project have to be documented and can affect both the budget and the appraised value the loan was approved against.
The mechanics of draws, inspections, contingency reserves and change orders work much the same way across all four construction programs, and our Maryland construction loans guide covers them in detail. What FHA adds is the contractor requirement, the property standards the completed home has to meet, and an appraisal tied to the plans and specifications you actually build to.
That structure exists to protect you. It means a builder cannot be paid in full for work that has not been done, and it means someone independent is checking progress against the plan.
Budget and contingency
A construction budget should include a contingency reserve for the things that surface once work is underway — material price movement, weather delays, change orders, conditions discovered on site. Construction lenders commonly require one, and the percentage they require varies by lender and by project scope rather than being set by a single FHA figure.
What happens if the project goes over budget
The contingency absorbs the first overruns. Beyond that, the practical options are that you contribute additional funds, or the scope is reduced to bring the project back within the approved budget.
There is a hard outer boundary regardless: the total project cost has to remain within the FHA loan limit for the county. Headroom below that limit is a real form of protection, and projects budgeted right up against the ceiling have none.
When the loan becomes your mortgage
When construction is finished, the local jurisdiction issues a Certificate of Occupancy — the document confirming the home has passed inspection and is legally fit to live in. That is the trigger.
At that point the loan converts to permanent financing at the terms established back at your single closing. You do not requalify. There is no second underwriting review, no fresh credit pull, no second set of closing costs and no second closing to attend.
When the first mortgage payment falls due after the Certificate of Occupancy is a matter of program and servicing practice rather than a fixed FHA rule, so confirm the specific timing with your lender rather than planning around a number you read somewhere.
How you appraise a house that does not exist yet
Reasonable question, and the answer explains why plans and specifications matter so much.
The appraiser values the proposed completed home, working from the construction plans, the specifications, the materials list and the builder’s cost breakdown, and comparing against recently completed comparable homes in the area. The value is of the finished house on that lot, not of the empty lot.
If the appraisal comes in below the project cost
It happens, and it is worth knowing the options in advance rather than in a panic. Generally: you bring additional funds to cover the gap, the builder reduces the contract price or scope to match, or the appraisal is challenged with additional comparable sales.
Whichever path is taken, the county FHA loan limit still applies on top.
The underlying risk is greatest where you are building something unusual for the area. If there are no comparable completed homes nearby, an appraiser has little to work from — which is why distinctive designs are harder to finance than conventional ones.
Builder requirements — and can you build it yourself?
HUD’s construction-to-permanent guidance requires that the borrower contract with a builder, and that the builder be a licensed general contractor. The builder is a party to the transaction, reviewed as part of the file.
Three separate gates apply to your builder, and passing one says nothing about the others. FHA requires the borrower to contract with a licensed general contractor and sets requirements for the construction documents and warranties. The lender reviews that specific builder’s experience, financial standing, insurance and references before agreeing to administer draws to them. Maryland separately requires home builders doing business in the state to be registered, which is a consumer-protection requirement rather than a lending one.
Our Maryland construction loans guide covers how to verify a builder’s state registration and what to confirm before signing a contract. Do that homework there; what matters here is that an FHA-eligible project still needs a builder your lender will approve.
Acting as your own general contractor
Because the rule requires contracting with a licensed general contractor, an owner-builder arrangement does not fit this financing — and construction lenders apply it strictly, since the builder is the single largest risk on the file.
If you are a licensed contractor in Maryland and want to build your own home, the practical route is to contract with a separate licensed builder for the project rather than expecting to fill both roles.
Beyond HUD’s requirement, individual lenders review builders against their own standards — licensing and trade registrations, general liability and workers’ compensation insurance, completed project history and references, financial stability, and the quality of the contract, plans, budget and draw schedule. Those specific criteria are lender policy rather than FHA rule, and they differ between lenders.
The practical consequence: your builder needs to be reviewed and accepted before closing. A builder who has never worked with construction financing can add weeks. Ask early whether they have done one.
FHA loan limits and why the Maryland county matters
Your total project — land, construction and any financed closing costs combined — has to fit within the FHA loan limit for the county where you are building. This is a genuine ceiling, and on a construction project it binds more often than people expect.
For 2026, HUD set the nationwide one-unit floor at $541,287 and the ceiling at $1,249,125, effective for FHA case numbers assigned on or after January 1, 2026.
Maryland spans nearly that entire range
This is one of the few places where the Maryland county genuinely changes the answer. The Washington metropolitan counties sit at the high end of the FHA range; other parts of the state sit considerably lower.
The practical effect: an identical house, built to identical specifications, may fit comfortably inside FHA financing in one Maryland county and exceed the limit in another. Land cost varies just as sharply across the state, and it counts toward the same total.
We are not publishing a county table here, because these figures are revised every year and a stale table would mislead. Confirm the current limit for your specific county with your lender, or check HUD’s official FHA mortgage limits lookup.
If your project exceeds the county limit, FHA financing will not stretch to it and you would be looking at a different construction product entirely.
FHA mortgage insurance on a construction loan
FHA charges mortgage insurance on this loan the same way it does on an FHA purchase, and on a build it deserves more attention than it usually gets, because you are choosing a mortgage you will hold for years while looking at a house that does not exist yet.
Two premiums apply. The upfront premium is 1.75% of the base loan amount, normally financed into the loan rather than paid at closing. The annual premium is collected monthly and set by HUD.
Duration is the part that shapes the decision. On a 30-year FHA loan, the annual premium is collected for 11 years when the loan-to-value is 90% or less, and for the life of the loan above that. At FHA’s 3.5% minimum investment you are above 90%, so the premium stays for the life of the loan.
Where land equity can change the math
If you already own the lot, the equity in it counts toward your investment. Enough land value can bring the loan-to-value on the completed project to 90% or below, which is the line where the annual premium ends after 11 years instead of running for the full term. That is worth calculating before you settle on a structure — it can be the difference of tens of thousands of dollars across the life of the loan.
Buyers often plan to refinance out of FHA mortgage insurance later. That can work, but it depends on the rates, your credit and the home’s value at that future point, none of which you can promise yourself today. If the long-term insurance cost is the deciding factor and you have the down payment for it, price a Conventional One-Time Close alongside this one before you commit.
What you need to qualify — and what is really an FHA rule
This distinction matters more on construction loans than on any other mortgage, and most published guidance blurs it.
FHA sets the program rules. Individual lenders add their own requirements on top, called overlays. On construction lending the overlays are typically substantial, because the lender is carrying build-phase risk that FHA’s baseline rules do not fully address.
| Topic | FHA program rule | What lenders commonly add |
|---|---|---|
| Minimum investment | 3.5%, satisfiable by land equity when building on your own land | Little variation — this one is fairly settled |
| Credit score | FHA’s standard minimum for 3.5% down is 580 | Construction lenders commonly require meaningfully higher scores |
| Debt-to-income | Assessed through underwriting rather than a single flat cap | Lenders may impose firmer internal ceilings on construction files |
| Builder | Must contract with a builder who is a licensed general contractor | Detailed approval standards — insurance, history, financials, references |
| Contingency reserve | Not expressed as a single fixed FHA percentage | Commonly required, sized by lender and project |
| Occupancy | Primary residence | Generally consistent |
| Loan limits | County FHA limit applies to the whole project | Generally consistent |
| Property types | FHA standards for eligible dwellings | Lenders often exclude unusual construction types outright |
| Timelines | Not a fixed FHA schedule | Lender-set closing and construction completion windows |
Why this matters practically: if one lender declines your scenario, that may be their overlay rather than an FHA prohibition, and a different construction lender may see it differently. Equally, a number quoted to you as “the FHA requirement” may simply be that lender’s policy. It is a fair question to ask directly.
What you can build
Conventional, widely-built housing is the comfortable centre of this program: stick-built single-family homes and modular homes are the standard cases. New manufactured housing may be financeable in larger configurations, subject to FHA’s manufactured housing rules on foundation and real-property titling, and single-wide mobile homes are excluded.
The home must be your primary residence. Second homes, vacation properties and investment builds do not qualify for FHA construction financing.
Unusual construction is harder — often for appraisal reasons
Distinctive building types — earth-sheltered homes, dome structures, container conversions, log construction, off-grid designs and similar — are frequently declined by construction lenders.
The reason is usually practical rather than ideological. Unusual homes are hard to appraise because comparable completed sales barely exist, and they are hard to finish if the original builder cannot complete the job, because few other builders can pick up the work.
Exclusion lists vary by lender rather than being one universal FHA list. If you are planning something out of the ordinary, establish financeability before you spend money on design work.
FHA compared with the other one-time close options
The detailed guides sit alongside this one: Conventional One-Time Close for the lower long-term mortgage insurance route, VA One-Time Close if you have entitlement, and USDA One-Time Close if both the lot and your income qualify. Maryland construction loans sets all four side by side.
| Program | Minimum down | Mortgage insurance | Typically best for |
|---|---|---|---|
| FHA | 3.5%, land equity may count | Upfront and annual MIP | Buyers with moderate credit or limited cash to close |
| VA | Up to 100% financing for eligible borrowers | No monthly MI; VA funding fee applies | Eligible veterans and service members |
| USDA | Up to 100% financing in eligible areas | Guarantee and annual fees | Building in a USDA-eligible area within income limits |
| Conventional | Higher, varies by product | Private MI, cancellable with equity | Stronger credit and a larger down payment |
Two decision rules are worth stating plainly. If you are VA-eligible, the VA route usually beats FHA on a construction project, because of the financing level and the absence of monthly mortgage insurance. And if you have strong credit and a substantial down payment, conventional financing may cost less over time, because its mortgage insurance can eventually be cancelled while FHA’s generally cannot.
Compare this option with other Maryland construction loan programs.
Our Maryland loan programs overview covers how the main financing routes differ.
Find out what you could build in your Maryland county
Your buying power, the county FHA limit and the realistic project total together define what is possible. Pre-approval establishes all three.
This is not a commitment to lend. All loans subject to credit approval.
Is FHA One-Time Close actually available?
This matters more than buyers expect. FHA permits construction-to-permanent financing, but permitting a structure and originating it are different things: many FHA lenders write purchase mortgages all day and never touch a construction file. Construction-to-permanent lending carries builder review, draw administration and inspection oversight that a standard purchase loan does not, so participation is more limited.
We currently offer FHA One-Time Close. That is a statement about what we can do today rather than a claim about the market. If you are shopping this product elsewhere, ask a direct question early: not “do you do FHA,” but “do you originate FHA One-Time Close construction-to-permanent loans, and have you closed one recently?”
When FHA One-Time Close makes sense — and when it does not
Strong fit
- You already own a Maryland lot and want the land equity to carry the down payment
- You want to build but have limited cash for a large construction down payment
- Your credit is moderate rather than excellent
- Rate certainty across a long build matters to you
- Your income or employment could realistically change before the house is finished
- Your total project fits comfortably inside the county FHA limit
- You are building a conventional home with a licensed builder
Weaker fit
- You are VA-eligible — the VA construction route is usually stronger
- You are building in a USDA-eligible area and meet the income limits
- You have strong credit and a large down payment, where conventional may cost less over time
- Your project exceeds the county FHA limit
- The home will not be your primary residence
- You want to act as your own general contractor
- You are renovating an existing home rather than building — that is an FHA 203(k), a different product entirely
- You want the freedom to shop the permanent mortgage after the build
The process, from pre-approval to move-in
- Get pre-approved. Credit, income, assets and buying power reviewed, and the applicable county FHA limit identified. This comes first — before land, before plans, before a builder deposit.
- Land and builder. Select the lot, or confirm the equity in one you already own, and identify a licensed builder. If the builder is new to construction lending, allow time for review.
- Plans, specifications and budget. The builder produces detailed plans, a materials specification and a cost breakdown. These drive both the appraisal and underwriting.
- Appraisal. The proposed completed home is valued against comparable finished properties.
- Underwriting. You and the project are reviewed together. Both have to work.
- One closing, before construction begins. All documents signed, permanent terms established, construction funds set aside.
- Construction. Permits pulled, work proceeds, funds released to the builder in inspected draws.
- Certificate of Occupancy. The jurisdiction confirms the home is complete and fit to occupy.
- Conversion and move-in. The loan becomes your permanent FHA mortgage on the terms already set. No requalifying, no second closing.
Expect the front end to take longer than a resale purchase. Plans, builder review, appraisal and underwriting all have to line up before you close. Permit timelines also vary considerably between Maryland jurisdictions, and municipalities often run their own permitting separately from the surrounding county — so confirm current lead times with your builder for the specific jurisdiction rather than assuming a statewide norm.
Common construction financing mistakes
- Buying the land before confirming the financing. The most expensive mistake on this page, and the most common.
- Budgeting for the house and forgetting the site. Well, septic, utilities, grading and stormwater can add materially on a raw Maryland lot.
- Ignoring the county FHA limit until the project is designed.
- Choosing a builder who has never done construction-loan work. They may be excellent builders and still add weeks to your file.
- Treating a per-square-foot estimate as a budget. Underwriting needs a real cost breakdown.
- Leaving no headroom under the loan limit, so there is nowhere to go if costs move.
- Assuming every requirement quoted to you is an FHA rule. Many are lender overlays, and overlays differ.
- Spending on architectural plans before qualification is established.
Frequently asked questions
Do I have to qualify again after construction?
No. That is the central advantage of the structure. You qualify once, before construction, and the loan converts to permanent financing at completion without a second underwriting review or a second closing.
When do mortgage payments start?
Payments on the permanent mortgage begin after the home is complete and the Certificate of Occupancy is issued. Exactly when the first payment falls due, and how construction-phase interest is handled, depends on the program rather than on a single FHA rule — confirm both with your lender.
What is a Certificate of Occupancy?
It is the document issued by the local building authority confirming the finished home meets code and is legally fit to occupy. On a one-time close it is the trigger that converts your construction loan into the permanent mortgage.
Can I be my own general contractor?
No. HUD’s guidance requires the borrower to contract with a builder who is a licensed general contractor, so an owner-builder arrangement does not fit this financing. A licensed Maryland contractor who wants to build their own home would need to contract with a separate licensed builder.
What credit score do I need?
FHA’s standard minimum for 3.5% down is 580, but construction lenders commonly require meaningfully higher scores as an overlay because of build-phase risk. There is no single industry-wide number, so ask the specific lender what they apply.
Does it have to be my primary residence?
Yes. FHA construction financing is for primary residences. Second homes, vacation properties and investment builds require different financing.
How do Maryland county FHA limits affect my project?
The total of land, construction and any financed closing costs must fit within the FHA limit for that county. Maryland spans a wide range — the Washington metropolitan counties are at the high end and other parts of the state considerably lower — so the same house can fit in one county and not another.
What happens if construction costs more than expected?
The contingency reserve absorbs the first overruns. Beyond that, you may need to contribute additional funds or reduce the scope, and the county FHA loan limit remains a hard ceiling regardless.
How long can construction take?
Completion windows are set by the lender and the construction contract rather than by one fixed FHA schedule, and Maryland permitting timelines vary by jurisdiction. Establish the expected schedule with your builder and lender at the outset.
Can I use down payment assistance with a construction loan?
Not with our FHA construction loan. Our current construction loan options do not include down payment assistance. Assistance programs are generally written around purchase transactions, and the Maryland Mortgage Program does not publish a construction-to-permanent product. If you need assistance to reach closing, a completed home is usually the workable path — see Maryland down payment assistance. Land you already own often does the same job here, since its equity can count toward the 3.5% requirement.
How is this different from an FHA 203(k)?
One-Time Close builds a new home from the ground up. FHA 203(k) finances renovation of a home that already exists. If there is a house standing on the lot and you are improving it, that is a 203(k) rather than a construction loan.
