FHA One-Time Close Construction Loans: What You Should Know Before You Build

One of the most misunderstood aspects of construction lending is how land functions within the transaction. Understanding this can save you thousands of dollars out of pocket.

If You Already Own the Land

If you currently own a plot of land in Washington, Carter, or Sullivan County, you are in a strong position. We can identify the appraised value of that land and apply it toward your required 3.5% down payment.

For example, if you own a lot free and clear that is worth $50,000, and your total project cost is $300,000, your required down payment would be roughly $10,500. Since your land equity ($50,000) far exceeds that requirement, you would not need to bring cash for the down payment. In fact, if the equity is strong enough, we can often roll your closing costs into the loan as well. In this scenario, your out-of-pocket requirement could be minimal to zero.

If You Are Buying Land

If you do not own land yet, you can purchase the land as part of the construction loan. We combine the cost of the land purchase and the cost of the build into one total project amount. You would then be responsible for putting 3.5% down on that total package, plus closing costs, unless you negotiate builder-paid concessions.

Mortgage Insurance Strategy

Because this is an FHA loan, it follows standard FHA mortgage insurance structures:

Upfront Mortgage Insurance Premium (UFMIP): Usually rolled into the loan amount.
Monthly Mortgage Insurance Premium (MIP): Paid as part of your monthly mortgage payment.

Currently, FHA mortgage insurance remains for the life of the loan if you put down less than 10%. However, many of our clients use FHA strategically. They build the home, establish 12 to 24 months of on-time payments, and see their credit scores rise—often from the low 600s to the mid-700s. Additionally, custom homes often appraise for more than the cost to build, creating instant equity. Once the home is complete and credit has improved, you may have the option to refinance into a conventional loan to remove the mortgage insurance.

Payments During Construction

A common question we receive is: “Do I have to pay the full mortgage while the house is being built?”

No. With FHA, you pay interest-only payments monthly, but only on the amount of money that has been drawn (paid out to the builder) so far. The calculation is straightforward: take the interest rate, multiply it by the outstanding balance, and divide by 12. This keeps payments low at the start of construction and gradually increases as the house nears completion.

Navigating Builders, Credit, and Risk

Choosing the right loan is only half the battle; choosing the right builder and understanding the process is the other half. Fortunately, the FHA One-Time Close loan is designed to work with a wide variety of home types and builders.

What Can You Build?

The guidelines for FHA construction are versatile. If we can build it with a VA loan, we can generally build it with an FHA loan. This includes:

Site-Built Homes: Traditional “stick-built” homes.
Modular Homes: Factory-built to local codes and assembled on-site.
Manufactured Homes: Factory-built to HUD codes (Double-wides, etc.).
Barndominiums: Permitted as long as comparable sales in the area support the value.

The Builder's Role

From a builder’s perspective, FHA loans are not significantly harder than other financing types. Builders are accustomed to draw systems. For manufactured homes, the draw schedule is typically set at 10% at closing, 80% upon delivery, and 10% at the certificate of occupancy. For site-built homes, construction usually spans 9 to 12 months with multiple progress-based draws.

From the lender’s standpoint, we perform a builder validation, not a deep financial quality approval. We verify their licensing and insurance and conduct a background check for legal issues. However, it remains the borrower’s responsibility to choose a builder with a solid reputation and quality workmanship.

Addressing Credit Imperfections

We understand that life happens. A 580 credit score usually has a story behind it, and the score itself doesn’t tell the full picture. If your credit profile is weaker, we look for “compensating factors” to strengthen your application, such as:

Strong, stable income.
Lower debt-to-income ratios regarding your other debts.
Cash reserves (savings left over after closing).
A larger down payment or significant land equity.

Is Building Riskier Than Buying?

Building a home isn’t necessarily riskier than buying an existing one, but it does have more moving parts. Weather can delay timelines in East Tennessee. Material costs can fluctuate. You will need to make many decisions regarding finishes and layouts.

Appraisals are also a critical factor. For example, if you are purchasing a large acreage tract, we sometimes recommend modular homes over manufactured homes. Modular homes are legally considered single-family residences and often appraise more favorably in rural scenarios, which protects your investment.

Where Should You Start?

The process is iterative, but here is the best order of operations:

Budget First: Decide what monthly payment you are comfortable with.
Speak with a Lender: Contact us to structure the loan based on your financial profile and determine your maximum budget.
Find Your Builder: Begin speaking with builders or manufactured home dealers with a clear pre-approval budget in hand.

For site-built homes, we typically require a 10% contingency fund built into the loan to cover unforeseen costs. For manufactured homes, this is not required. Understanding these nuances early prevents surprises later.

Q1: Can I use an FHA One-Time Close loan for a manufactured home?

Yes, absolutely. FHA OTC loans can be used for manufactured homes (double-wides and larger) as long as they are placed on a permanent foundation and titled as real property. The draw schedule is slightly different than site-built homes, but it is a very common use of this program.

Q2: Do I have to make full mortgage payments while the home is being built?

No. You only pay interest on the funds that have been paid out to the builder so far. You do not pay principal or the full mortgage payment until construction is complete and the loan converts to the permanent phase.

Q3: Can I act as my own builder (Owner-Builder)?

Generally, no. FHA guidelines typically require a licensed, third-party general contractor to oversee the project. This protects both you and the lender to ensure the home is completed to code and on time.

Q4: What if the cost of construction goes over budget?

For site-built homes, we include a contingency reserve (usually 10%) in the loan amount to cover unexpected overages. If you have significant cash reserves, you may be allowed to self-fund this contingency, but having it in the loan is safer for most borrowers.

Q5: How long does the process take?

The lending side moves relatively quickly—similar to a standard purchase. However, the construction phase depends on the builder and the type of home. Manufactured homes can be set in a few months, while site-built homes typically take 9 to 12 months to complete.
