You cannot use an FHA loan to buy raw land by itself, but you can finance the lot and the home you plan to build on it together through a single FHA-insured mortgage. The program that makes buying land with an FHA loan possible is the One-Time Close construction loan, which rolls the land purchase, the construction costs, and the permanent mortgage into one closing with a minimum down payment of 3.5 percent. If you already own the lot, your equity in it can cover that down payment. The condition attached to all of this is that FHA will only back the land when it is tied to an immediate plan to build your primary residence on it.
How the One-Time Close Loan Bundles Land and Construction
Most construction financing runs on two closings: one loan to pay for the build, a second to convert the balance into a regular mortgage. The FHA One-Time Close removes that second closing. You qualify once, sign once, and the loan shifts automatically from construction financing to a permanent mortgage after the home is built and the local government issues a certificate of occupancy. During construction you typically make interest-only payments on whatever portion of the loan the lender has actually released to the builder.
The single loan covers three things. It pays for the land, either by funding the purchase or by paying off a lot loan you already have. It funds the build itself according to your builder’s fixed-price contract. And it becomes the long-term mortgage that replaces both once the house is finished.
Using Land You Already Own as Your Down Payment
If you own the lot outright, the equity in it counts toward the 3.5 percent down payment on the total loan. In many cases that equity covers the requirement in full and eliminates the need to bring additional cash to closing. If you still owe money on the land, the outstanding balance gets paid off as part of the new loan. If you are buying the lot as part of the transaction, the purchase price rolls into the mortgage and the seller is paid at closing.
Occupancy is not optional. FHA will not insure a One-Time Close loan for a vacation home or a rental property. You have to intend to live in the finished house as your primary residence.
Which Lots Actually Qualify
FHA will not insure a mortgage on just any parcel. The land has to meet physical, legal, and environmental standards before a lender can approve the loan. These rules exist to protect both the borrower and the FHA insurance fund by making sure the finished home is safe, livable, and holds its value.
Zoning, Road Access, and Utilities
The lot has to be a buildable residential parcel that complies with local zoning and land-use restrictions. It needs direct access to a road with an all-weather surface, so emergency vehicles can reach the property year-round. It also has to connect to basic infrastructure: potable water, a sewage disposal system, and electricity.
Where public utilities are not available, the property can still qualify with private systems that meet local health department codes. For a private well and septic setup, FHA requires at least 100 feet between the well and the septic drain field, and the well must sit at least 10 feet from any property line. State or local rules that demand greater distances take precedence.
Flood Zones and Environmental Hazards
Flood zone status can end an FHA deal before it starts. New construction in a Special Flood Hazard Area is not eligible for FHA insurance. Properties in the Coastal Barrier Resources System are also ineligible regardless of property type. Check FEMA’s flood maps for any lot you are seriously considering, because finding out about a flood designation after paying for surveys and blueprints is an expensive mistake.
Other environmental factors can disqualify a site too. If the lot sits within a high-voltage transmission line easement or near a cell tower, the appraiser has to determine whether the planned home would fall within the tower’s engineered fall distance. Proximity to explosive or flammable storage, contaminated sites, and heavy noise sources such as airports can also knock a property out under HUD’s environmental criteria.
Acreage and Land Value
The lot has to be a reasonable size for residential use in your area. FHA will not finance large agricultural tracts or commercial farmland. The land value also cannot make up an outsized share of the total property value, because the loan is meant to finance a dwelling, not primarily the ground under it. Your appraiser judges that ratio using comparable properties nearby.
Borrower Qualifications
Passing the property test is only half the job. You also need to qualify financially, and construction loans carry slightly tighter standards than a regular FHA purchase mortgage because the lender is financing a house that does not yet exist.
Credit Score
FHA’s baseline rule allows the 3.5 percent down payment with a credit score of 580 or higher. Lenders that actually offer the One-Time Close product typically set their own minimums higher — commonly 620, with some requiring scores in the mid-600s. Expect stricter credit review than you would face on an existing home.
Debt-to-Income Ratio
FHA uses two ratios. Your front-end ratio, the share of gross monthly income going to housing costs, should generally stay at or below 31 percent. Your back-end ratio, housing costs plus all other recurring debts, should stay at or below 43 percent. These are not hard ceilings. Borrowers with strong compensating factors like substantial cash reserves, rising income, or minimal non-housing debt can qualify with ratios up to 50 percent, and automated underwriting sometimes approves higher.
Loan Limits
Your total loan, land plus construction combined, cannot exceed FHA’s loan limit for your county. For 2026, the national floor for a single-unit property is $541,287 and the ceiling in high-cost areas is $1,249,125.1U.S. Department of Housing and Urban Development. HUD’s Federal Housing Administration Announces 2026 Loan Limits Many counties fall between those two numbers. Look up your specific county limit on HUD’s website before you finalize a build budget.
Mortgage Insurance Premiums
Every FHA loan carries two layers of mortgage insurance. You pay an upfront premium of 1.75 percent of the base loan amount, typically rolled into the loan balance rather than paid at closing. You also pay an annual premium collected in monthly installments. On a 30-year loan with more than 5 percent down, the annual rate is 80 basis points (0.80 percent). With the minimum 3.5 percent down, meaning an LTV above 95 percent, the annual rate rises to 85 basis points (0.85 percent) and stays in place for the life of the loan.2U.S. Department of Housing and Urban Development.

Documents and Builder Requirements
FHA construction loans involve much more paperwork than a standard home purchase. Having everything ready before you apply can save weeks.
You need a fixed-price construction contract from a licensed, insured general contractor covering the full scope of work and a projected completion timeline. Finalized architectural blueprints and site plans go with it, because the appraiser uses them to estimate what the finished home will be worth. Two HUD forms sit at the center of the application: form HUD-92900-A, which captures your finances, the builder’s identity, and the total construction cost, and form HUD-92005, the Description of Materials, which itemizes every major component of the planned home so the lender can confirm it meets FHA’s Minimum Property Standards. Errors on either form can cause delays or denial.
Your builder has to carry general liability insurance and hold a valid state license. FHA does not run a formal builder approval program, but the lender reviews the builder as part of underwriting. The builder must also execute a Warranty of Completion of Construction (form HUD-92544) and give you a one-year warranty covering defects in equipment, materials, and workmanship. That warranty starts at whichever comes first: title transfer, completion of construction, or the date you move in.3U.S. Department of Housing and Urban Development. Mortgagee Letter 2019-05
On top of that, expect to provide the standard financial paperwork: two years of tax returns, recent bank statements, pay stubs, and verification of employment. If you already own the land, bring a deed or title report; if you are buying it, bring the executed sales contract for the lot.
Closing, Draws, and Conversion to a Permanent Mortgage
Once your documentation is complete, the lender orders a “subject to completion” appraisal based on your plans and the Description of Materials. That appraisal estimates what the home will be worth once built, and that value sets the maximum loan the lender can approve.
At closing, the full loan amount does not hand over to the builder. The lender places construction funds in an escrow account and releases them in stages as the builder hits specific milestones. Each disbursement requires an inspection confirming the completed work matches the blueprints and FHA standards, and materials sitting on site but not yet installed cannot be included in a draw. Only acceptably completed work qualifies for payment. During this phase you make interest-only payments based on the amount actually disbursed, not the full loan balance.
When construction finishes and the local government issues a certificate of occupancy, the loan converts into a standard amortizing mortgage. No second closing. Your interest rate, term, and monthly payment were locked in at the original closing, and you shift into regular principal-and-interest payments for the rest of the term.
Manufactured and Modular Homes on Land
If building from the ground up does not fit your budget, FHA also insures loans for manufactured homes placed on land you own or are buying. To qualify under FHA’s Title II program, the home must have been built after June 15, 1976, must carry a HUD certification label confirming it meets federal construction and safety standards, and must have a minimum floor area of 400 square feet.4HUD. Manufactured Homes – Eligibility and General Requirements – Title II
The biggest requirement is the permanent foundation. The home must sit on a site-built foundation of durable materials — concrete, mortared masonry, or treated wood — designed by a licensed professional engineer. Footings must extend below the maximum frost-penetration depth, with reinforced concrete at the base, and the foundation must anchor the home so all loads transfer to the underlying soil. Screw-in soil anchors do not qualify. If you are buying a manufactured home already sited on land, the existing foundation has to meet these standards or the loan will not be approved.
Costs the Loan Won’t Cover
Several out-of-pocket expenses come up during the process that your FHA loan will not pay for. Plan for them early, because running short partway through construction can stall the project and put your loan approval at risk.
- Land survey. A professional boundary survey is typically required before closing. For a standard residential lot, expect roughly $500 to $1,800 depending on terrain and size. Heavily wooded, sloped, or unusually shaped parcels cost more.
- Soil percolation test. If the property will rely on a septic system, most local health departments require a perc test confirming the soil can absorb wastewater. Costs run from around $300 to $3,000 depending on how many test holes are required and what equipment is needed.
- Building permits. Local permits for new single-family construction usually run between $1,000 and $3,000. Many jurisdictions calculate the fee as a percentage of total project value, and that number often excludes separate trade permits for plumbing, electrical, and HVAC.
- Upfront mortgage insurance. The 1.75 percent upfront FHA premium on a $400,000 loan adds $7,000 to your balance. It is financed rather than paid at closing, but it still raises your total debt and monthly payment.
One Program That Won’t Help Here
FHA’s 203(k) Rehabilitation Mortgage also bundles a purchase and improvement costs into a single loan, and it comes up often in searches about buying land. It does not apply to vacant land. The 203(k) only covers homes that already exist and are at least one year old.5HUD. 203(k) Rehabilitation Mortgage Insurance Program If you are buying a lot to build on, the One-Time Close construction loan is the FHA route.
