FHA One-Time Close Construction Loan in Delaware: Build Your Home With One Loan and One Closing

I’m John Thomas, NMLS #38783, and I’ve been writing about and originating FHA construction loans for Delaware and Maryland buyers for over 20 years. The FHA One-Time Close (OTC) is one of the most misunderstood programs in the lending world – most lenders won’t touch it, most builders have never heard of it, and most buyers who actually want to build their own home end up getting talked into a two-time-close arrangement that costs them thousands of dollars more than it should. The single biggest reason to use the FHA OTC instead of a two-time close is the part most lenders gloss over: you only qualify once, you only close once, and your permanent rate is locked before construction even starts. If you want to skim the differences before reading the full guide, jump down to the OTC vs. Two-Time Close comparison table – and if you already own your land, also check the Delaware down payment assistance section below because your land equity may cover your entire 3.5% required investment.

How Does the FHA One-Time Close Construction Loan Work in Delaware?

Two isn’t always better than one – let me explain. If you’re building your house from the ground up the traditional way, you’ll most likely take a construction loan followed by a permanent loan. That scenario requires two loans, which means two applications, two qualification reviews, two appraisals, two closings, and two sets of closing costs. The FHA One-Time Close construction loan combines all of that into a single mortgage. You apply once, you qualify once, you close once – before construction begins – and when your builder finishes the house, your loan automatically converts into a 30-year fixed-rate Delaware FHA Loan without a second closing.

Let me break down the term piece by piece so the loan name actually makes sense. FHA stands for the Federal Housing Administration – an FHA loan is a mortgage issued by an FHA-approved lender and insured by HUD, designed to help low-to-moderate income borrowers buy a home with a lower minimum down payment and more flexible credit guidelines than most conventional loans. A construction loan is a short-term loan used to finance the building of a home – funds are released to the builder in draws as the project hits construction milestones, and at the end of the project the loan either has to be paid off in full or replaced with permanent financing. A one-time close construction loan wraps both pieces together: you sign the documents once, the construction phase happens, and when the home receives its Certificate of Occupancy your interest-only construction note quietly converts into your permanent FHA mortgage. One loan. One closing. One set of fees.

Also called the FHA OTC, FHA single-close construction loan, or FHA construction-to-permanent loan – all four names refer to the same product backed by the same underlying HUD rules. HUD’s official FHA construction loan reference covers the federal program rules; this page covers the Delaware-specific application.

FHA One-Time Close vs. Two-Time Close Construction Loan: Side-by-Side Comparison

Here’s how the FHA OTC stacks up against the traditional two-time close arrangement that most local banks and credit unions offer. This is the comparison most buyers never see clearly explained:

Feature	FHA One-Time Close	Two-Time Close Construction
Number of closings	1 (before construction)	2 (one for construction, one for permanent)
Closing costs paid	One set	Two sets
Permanent rate locked	Before construction starts	After construction finishes (market risk)
Re-qualification needed after build	No	Yes – credit, income, employment all re-checked
Risk if you lose your job mid-build	Already approved – construction continues	May fail to qualify for permanent loan
Minimum down payment	3.5% (land equity may count)	Typically 10%-20%
Mortgage payments during construction	None until Certificate of Occupancy	Interest-only construction payments
Float-down on rates if they improve	Yes (program-dependent)	Whatever rate is available at second closing

Advantages of an FHA One-Time Close Construction Loan

If you like one-stop shopping, the FHA OTC is going to appeal to you. Here’s what you’re actually getting when you choose this structure over a two-time close:

• One application, one closing. You go through the qualification process once – credit, income, employment, assets, appraisal – and you’re done. No re-qualifying after the house is built.
• One set of closing costs. Two-time-close arrangements stack closing costs twice. The cost difference isn’t always dramatic, but a saved closing cost is a saved closing cost.
• Interest costs during construction can be rolled into the loan. Most FHA OTC programs (including ours) let you finance the construction-phase interest into the permanent loan, so you have no out-of-pocket mortgage payments while your home is being built.
• Added security if your job situation changes. With a one-time close, if you lose your job during the construction phase, you’ve already been approved – the construction continues and the loan converts to permanent at the end. With a separate two-time-close, you’d have to re-qualify with the new employment situation, which often kills the deal mid-build.
• You can lock your permanent rate before construction starts. If rates are rising, this protects you. If rates fall meaningfully during construction, our program allows a float-down option at closing.
• You can plan your monthly payment in advance because the permanent rate is set up front. No guessing where rates will be 6-9 months from now.

Disadvantages of an FHA One-Time Close Construction Loan

I’m not going to pretend there are no trade-offs. Here are the honest disadvantages, with scenario context so you can decide whether they actually affect you:

• FHA OTC rates may run slightly higher than a standard FHA purchase loan because the lender is taking construction-phase risk. The trade-off is the lower risk and convenience of a single closing – and our float-down option means if rates improve before your home is finished, you don’t get stuck with the higher rate anyway. Rates change daily – call 302-703-0727 for the current rate quote on your scenario.
• You’re tied to one lender for both phases. If you wanted to shop around for the permanent mortgage after construction was done, a two-time close gives you that flexibility – but it also gives you the risk of not qualifying for the permanent loan when the time comes. Most buyers who already have a lender they trust prefer the certainty of one-time close.
• The builder approval process is more involved. Your builder must be approved by the lender before closing – we verify licensing, insurance, financial stability, and project portfolio. If you have a specific builder in mind who has never worked with FHA construction financing before, we’ll work through the approval together, but it takes time. Builders who are already in our approved network can close faster.

What Are the Requirements to Qualify for an FHA One-Time Close Construction Loan?

Here’s the fast-reference snapshot of what you need to qualify for the FHA One-Time Close Construction Loan in Delaware. Each row is expanded in the detail list below the table:

Requirement	FHA OTC Standard
Minimum credit score	620 middle FICO (all borrowers)
Minimum down payment	3.5% of total project cost (land equity may count)
Maximum DTI ratio	43% standard; up to 56% with compensating factors
Gift funds for down payment	Allowed – up to 100% from family or approved donor
Seller / builder concessions	Up to 6% toward closing costs and prepaid items
Property type	Stick-built, modular, or new manufactured (double-wide+)
Occupancy	Primary residence only
Builder approval	Required before closing; lender-approved builder only
Owner as general contractor	Not allowed – FHA requires a licensed approved builder
2026 FHA loan limit (1-unit, NCC)	$630,200
2026 FHA loan limit (1-unit, Kent & Sussex)	$541,287
Typical closing timeline	30-60 days from application, depending on builder + appraisal
Typical construction timeline	6-12 months, varies by project scope and permit timing
First mortgage payment	30-60 days after Certificate of Occupancy

To qualify for the FHA One-Time Close Construction Loan in Delaware or Maryland, you must meet the following guidelines:

• Minimum middle FICO score of 620 for all borrowers. The FHA program technically allows scores as low as 500 (with 10% down at 500-579), but the construction-loan overlay across most lenders requires 620 due to the added complexity of the build phase.
• Maximum debt-to-income (DTI) ratio of 43% under standard FHA guidelines, with the possibility of going up to 56.9% with compensating factors such as substantial reserves, a higher credit score, a lower payment shock, or significant residual income. DTI is calculated against your projected permanent mortgage payment plus existing debt obligations.
• The new home must be your primary residence. FHA OTC does not finance second homes, vacation properties, or investment properties.
• Minimum investment of 3.5% of total project cost. If you already own the lot, the appraised value of the land equity can count toward the 3.5%. Gift funds from a family member or an approved donor are also permitted and may cover up to 100% of the required down payment under standard FHA gift fund rules.
• Sellers and builders may contribute up to 6% toward closing costs and prepaid items. Contribution amounts beyond the 6% cap are reduced dollar-for-dollar from the loan amount per FHA rules.
• Property type must be stick-built, modular, or qualifying new manufactured housing (double-wide or larger; single-wide mobile homes are excluded).
• The closing occurs before construction begins. All loan documents are signed up front, then construction starts and the lender releases funds to the builder in draws.
• Closing costs can be financed into the FHA loan when included in the final project price, subject to FHA county loan limits. This reduces your cash to close.
• No mortgage payments are due until you receive your Certificate of Occupancy. Construction-phase interest is rolled into the loan.
• The builder must be registered by the lender prior to closing. Licensing, insurance, financial stability, and project portfolio are all reviewed. Borrowers are not permitted to act as their own general contractor under FHA OTC – a licensed, lender-approved builder is required.
• Total project cost (land + construction + financed closing costs) must fit within FHA county loan limits – see the 2026 Delaware FHA loan limits table below.
• Contingency reserve of 5%-10% of project cost is strongly recommended (and required by some FHA construction lenders) to cover unforeseen construction overruns. See the Project Budget section below for details.

2026 Delaware FHA Loan Limits for Construction Projects

FHA construction loans are subject to the same FHA county loan limits as regular FHA purchase loans. Your total project cost (land + construction + any financed closing costs) cannot exceed these limits or you will need a Jumbo construction loan instead. Here are the 2026 Delaware FHA loan limits as published by HUD:

Property Type	New Castle County	Kent & Sussex Counties
1-unit	$630,200	$541,287
2-unit	$806,750	$693,050
3-unit	$975,275	$837,700
4-unit	$1,211,950	$1,041,125

If you’re building in New Castle County, you have meaningful room – a 1-unit project up to $630,200 fits the FHA OTC envelope, which covers the vast majority of new-construction projects in the Newark, Bear, Middletown, Hockessin, Pike Creek, and Wilmington markets. In Kent and Sussex Counties (Dover, Smyrna, Lewes, Rehoboth, Milford, Seaford), the 1-unit limit drops to $541,287 – still workable for most stick-built or modular projects, but worth checking against your total construction budget before you sign a land contract.

Building in Maryland? Maryland FHA loan limits vary meaningfully by county – counties on the Eastern Shore have different limits than Cecil, Harford, and Baltimore counties. Call 302-703-0727 and we will look up the exact 2026 FHA loan limit for the specific Maryland county where you’re building. You can also verify current FHA county limits directly through the HUD FHA Mortgage Limits lookup tool.

What Property Types Are Allowed for the FHA Construction Loan?

The following property types are eligible for FHA One-Time Close construction financing:

• Single-family residence (stick-built – the most common configuration)
• Manufactured or modular home (must be new construction; manufactured housing must be double-wide or larger – single-wide mobile homes are excluded by FHA)
• Barndominiums – must have comparable sales in the area to support the appraisal
• Kit homes – the client may need to finance the materials separately because the lender cannot release funds for materials until they are on-site
• Tiny homes – no minimum square footage, but the appraiser must be able to find comparable sales in the area

What Property Types Are NOT Allowed for the FHA OTC Construction Loan?

The following property types are excluded from FHA One-Time Close construction financing – the primary reason for these exclusions is that non-standard construction types are considered unique properties, are difficult to find appraisal comparables for, and require specialized construction techniques that make builder substitution mid-project very difficult if the original builder is unable to finish the job:

Log Cabin Homes

Pre-cut kits for log buildings that are assembled on site.

Shipping Container Homes

A dwelling made from a steel container otherwise used for shipping.

Stilt Homes

Houses raised on piles over land or a body of water.

Solar-Only or Wind-Only Powered Homes

Homes powered on-site solely by solar panels or solely by wind turbines without grid backup.

Dome Homes

Homes built in the shape of a sphere using shell framework.

Bermed Earth-Sheltered Homes

Homes with earth (soil) against the walls, roof, or buried underground.

Single-Wide Mobile Homes

FHA excludes single-wide mobile homes from the OTC program. New manufactured housing in double-wide or larger configurations is allowed.

Accessory Dwelling Units (ADUs)

Additional living quarters independent of the primary dwelling. ADUs must be financed with a renovation loan product such as the FHA 203(k) Rehab Loan, not with the OTC construction loan.

A-Frame Houses

Buildings with the tall triangular roof shape resembling the letter A.

Project Budget, Contingency Reserve, and Delaware Permit Timing

This is the section most lender websites skip. Construction loans are not regular purchase loans – your project carries timeline risk, cost-overrun risk, and permit-jurisdiction risk that simply do not exist on a resale purchase. Here is how we address each one up front so you are not caught off guard mid-build:

Contingency Reserve: 5%-10% of Project Cost

FHA construction standards strongly recommend (and many FHA construction lenders require) a contingency reserve of 5%-10% of total project cost to cover unforeseen overruns – material price increases, weather delays, change orders, or scope adjustments that come up during the build. On a $400,000 project, a 5% contingency is $20,000 and a 10% contingency is $40,000. The contingency can typically be financed within the project budget when project total stays within the FHA county loan limit, or held separately by the borrower as liquid reserves. We work with you and your builder during application to size the reserve appropriately for your specific scope.

What We Review for Builder Approval

Your builder is the single biggest variable on a construction loan, which is why FHA requires lender-approved builders and prohibits owner-as-general-contractor scenarios. When you bring a builder into the file, here is what we review before approval:

• Active state contractor license and required local trade licenses
• General liability and workers’ compensation insurance
• Two to three years of completed project history with references
• Fixed-price contract or contract with clear allowance schedule
• Complete construction plans, specifications, and material lists
• Detailed project budget aligned to the appraiser’s cost-approach valuation
• Site information including soil testing, utility availability, and zoning compliance
• Draw schedule with clear inspection milestones

If your builder is already in our approved network, the approval review is fast. If we are reviewing a new builder, plan on roughly 1-2 weeks of additional underwriting time while documentation is verified.

Permit Timing in Delaware Counties

Permit timelines vary meaningfully across Delaware’s three counties. New Castle County, Kent County, and Sussex County each run their own building department with its own review queue, plan-examiner staffing, and inspection cadence. Sussex County beach markets (Lewes, Rehoboth, Bethany, Dewey) often run longer review timelines during peak permitting seasons. Some municipal building authorities – Wilmington, Dover, and Newark in particular – handle their own permits inside city limits separately from the surrounding county.

We strongly recommend confirming current permit lead-times with your builder for your specific jurisdiction before you sign a land contract or schedule a closing date. A rate lock that expires before permits clear is a recoverable inconvenience, but it is an avoidable inconvenience if everyone plans around the right permit timeline up front.

Example Project Cost Math (3.5% Minimum Investment)

The 3.5% FHA minimum investment is a fixed percentage of total project cost. Here is what that works out to at a few common Delaware project sizes:

Example Project	Estimated Total Project Cost	3.5% Minimum Investment
Entry-level build	$350,000	$12,250
Mid-range build	$450,000	$15,750
New Castle County upper FHA range	$600,000	$21,000
NCC at 2026 FHA county limit (1-unit)	$630,200	$22,057

If you already own the lot, your land equity can satisfy some or all of the 3.5% minimum investment shown in the right column. On the $600,000 NCC example, a buyer who already owns a $100,000 lot would only need approximately $5,000-$10,000 additional cash at closing (subject to appraisal and full project review), since the $100,000 land equity vastly exceeds the $21,000 minimum investment requirement.

Can I Use Down Payment Assistance With an FHA Construction Loan?

This is one of the most-asked questions I get on construction loans, and the answer is no. Down payment assistance does not pair with an FHA One-Time Close construction loan. Delaware’s assistance programs – DSHA Welcome Home, Open Door and the DPA tiers that sit under them, along with the county and city programs – are all built around the purchase of an existing home, and none of them can be layered onto a construction loan. That is a program-design limitation rather than a lender preference, so shopping other lenders will not change it.

What this means for you. Plan on funding the 3.5% down payment yourself on an FHA OTC build. The good news is that the other FHA flexibilities still apply: documented gift funds from an approved donor are permitted, the 620 credit floor is unchanged, and because the loan is sized against the appraised value of the finished home rather than the purchase price of an existing one, buyers with land equity often need less cash than they expect. If you need down payment assistance to make the numbers work, buying an existing home with standard FHA financing and DSHA assistance is the realistic path – call 302-703-0727 and we will price both so you can see the difference.

How the Process Works From Application Through Move-In

From the day you call my team at 302-703-0727 to the day you walk into your finished home, here’s roughly what happens. Steps 1-3 are the front-loaded qualification and design work; steps 4-6 are the build phase; step 7 is move-in:

1. Pre-qualification. We review your credit, income, employment, and assets. We confirm your buying power and identify which FHA county limit applies based on where you want to build. Typically 1-3 days.
2. Land and builder selection. You select your lot (or use one you already own) and choose a builder. We review the builder for FHA approval if they aren’t already in our network. Typically 1-2 weeks for builder approval if new to our network; faster if already approved.
3. Construction plans and appraisal. The appraiser values the project based on the proposed completed home. Plans, specs, and cost estimates are reviewed by underwriting. Typically 2-3 weeks, depending on appraisal turn-times in your county.
4. One closing – before construction begins. You sign all documents. The permanent rate is locked. Funds for construction are placed in an escrow account. Total from application to closing typically 30-60 days, depending on builder readiness, appraisal speed, permit timeline, and underwriting complexity.
5. Construction phase. Your builder draws funds from escrow as each phase is completed. Interest accrues during construction and is rolled into your final loan balance (no out-of-pocket mortgage payments). Typical construction phase is 9-12 months, though scope and weather meaningfully affect the timeline.
6. Certificate of Occupancy. When the home is finished and the local building department issues the CO, the loan automatically converts to a 30-year fixed FHA mortgage at the rate you locked back in step 4 – unless rates have fallen meaningfully and you exercise the float-down option (see below).
7. Move-in and first mortgage payment. Your first mortgage payment is typically due 30-60 days after CO. Welcome home.

How the Float-Down Option Works

If interest rates fall meaningfully between your closing date and the date your home receives its Certificate of Occupancy, our program offers a one-time float-down option at the conversion to permanent financing. The float-down lets you capture the lower market rate at conversion without going through a re-application or re-underwriting process. Float-down terms – including the minimum rate-improvement threshold, any associated fee, and timing requirements – are subject to the program rules current at the time of conversion. Talk to your loan officer at closing to understand the specific float-down terms applicable to your loan.

When the FHA One-Time Close Construction Loan Is Not a Good Fit

Most lender content about construction loans tells you when the program works. I’d rather tell you when it doesn’t, because the wrong loan product on a construction project is an expensive mistake. Here are the buyer scenarios where the FHA One-Time Close is the wrong choice and what to use instead:

• You’re a veteran with full VA entitlement. If you’re VA-eligible, the VA One-Time Close Construction Loan typically beats FHA OTC because it allows up to 100% financing (zero down) and has no monthly mortgage insurance. Only choose FHA over VA in narrow scenarios.
• You’re building in a USDA-eligible rural area. If your build site qualifies under the USDA rural area map, the USDA One-Time Close Construction Loan offers zero down with no monthly MI on the construction side. Worth checking your address before defaulting to FHA.
• You have a 740+ credit score and 20%+ down. The mortgage insurance math on FHA stops making sense at strong credit + large down. A Conventional One-Time Close Construction Loan will likely save you money on monthly MI over the life of the loan.
• Your total project cost exceeds the county FHA loan limit. If you’re building over $630,200 in New Castle County or over $541,287 in Kent/Sussex, FHA OTC will not fit and you need a Jumbo One-Time Close Construction Loan instead.
• You want to build a log cabin, shipping-container home, dome home, or other non-allowable property type. FHA OTC excludes these specifically. You’ll need a portfolio construction product from a specialty lender – call 302-703-0727 and we can talk through alternatives.
• You’re not planning to live in the home as your primary residence. FHA OTC is primary-residence only. Second homes, vacation rentals, and investment properties require conventional or non-QM construction financing.
• You’re planning to renovate an existing home rather than build a new one. That’s a rehab loan, not a construction loan. The FHA 203(k) Rehab Loan covers existing-home renovation; FHA OTC covers ground-up new construction.

FHA OTC vs. VA OTC vs. USDA OTC vs. Conventional OTC: Which One-Time Close Construction Loan Fits Your Situation?

If you’re trying to figure out which one-time close construction loan is the right fit, here’s the side-by-side. All four are available through the John Thomas Team with AnnieMac Home Mortgage in Delaware and Maryland – call my team and we’ll walk through the math on your specific scenario:

Program	Min Down	Min Credit	Mortgage Insurance	Best Fit
FHA OTC	3.5%	620	Upfront + monthly MIP (life of loan)	Most first-time buyers, lower credit, smaller down payment
VA OTC	0%	620 (lender overlay)	None – VA funding fee instead	Eligible veterans and active-duty service members
USDA OTC	0%	640 (typical)	Annual fee + upfront guarantee fee	Buyers building in USDA-eligible rural areas, income within USDA limits
Conventional OTC	5%-20%	620-680	PMI if under 20% down (cancellable)	Buyers with strong credit, larger down payment, want to avoid life-of-loan MI

Who the FHA OTC Construction Loan Fits Best in Delaware and Maryland

Most buyers who land on this page fall into one of three profiles. If you recognize yourself in any of these descriptions, the FHA One-Time Close Construction Loan is likely a strong fit:

• First-time buyer with a moderate credit score and limited savings who wants to build instead of competing for resale inventory. The 3.5% down payment requirement and the 620 credit floor together make ground-up construction realistic for buyers who would otherwise be locked out by 20% conventional construction down payment requirements.
• Buyer who already owns the lot and wants to use the land equity as the entire 3.5% down payment. This is a clean fit because FHA OTC explicitly allows lot equity to satisfy the minimum investment requirement, which means many buyers in this category come to closing with very little out-of-pocket cash.
• Repeat buyer who wants rate certainty during a market with rate volatility. Locking the permanent rate before construction starts removes the risk of paying significantly more on the permanent loan if rates jump during your build – and the float-down option means if rates fall meaningfully before your home is finished, you can capture the lower rate at conversion without re-applying.
