If you already own the lot, you can finance the build with a construction loan that treats your land equity as all or part of the down payment, releases money in stages as the house goes up, and converts to a regular mortgage once it’s finished. That is the short answer to how to get a loan to build a house on your land. The longer answer involves choosing between two loan structures, meeting tighter credit and documentation standards than a standard mortgage, proving the land is buildable, and vetting a builder the lender will accept.
One-Time Close or Two-Time Close
The first real decision is whether to use a single-close construction loan or a two-close structure. It affects your rate risk, your closing costs, and how much paperwork you handle.
A one-time close loan (also called construction-to-permanent financing) bundles the construction loan and the permanent mortgage into a single closing. You sign one set of documents, pay one round of closing costs, and lock the permanent interest rate before construction begins. When the house is done, the loan converts automatically. Fannie Mae purchases these loans after construction is complete and the terms have converted to permanent financing.1Fannie Mae. B5-3.1-02, Conversion of Construction-to-Permanent Financing: Single-Closing Transactions
A two-time close splits construction and permanent financing into separate transactions. You close on the construction loan first, then close again on a traditional mortgage after the home is built. The upside is flexibility: you can shop rates when construction wraps up and switch lenders if that gets you a better deal. The downside is cost. Two sets of closing costs, two appraisals, two rounds of title work. And if rates have risen during the build, your permanent mortgage will cost more than you planned.
For most landowners building a primary residence, the one-time close is the safer choice. The two-time close makes sense mainly if you expect rates to drop during construction or if your preferred lender doesn’t offer a single-close product.
How Your Land Equity Covers the Down Payment
Owning the land is the biggest financial advantage you bring to the table. Most lenders count your land equity toward the down payment, which can mean little or no cash out of pocket at closing.
The math works like this. A certified appraiser determines the current market value of your land, and the lender subtracts any remaining balance on a land loan. If you own the parcel free and clear, the full appraised value counts as equity. That equity is then measured against the total project cost (land value plus construction budget) to produce a loan-to-value ratio.
Conventional construction loans typically require 20% equity in the total project. If your land appraises at $80,000 and you plan to build a $320,000 home, the project totals $400,000. Your $80,000 in land equity is exactly 20%, and you would owe nothing more for the down payment. If you still owed $30,000 on the land, your equity would drop to $50,000, or 12.5%, and you would need to bring cash to make up the difference. FHA loans need only 3.5% equity, and VA and USDA loans can work with zero cash down when the land equity covers the requirement.
Government-Backed Construction Loans
If a conventional construction loan feels out of reach, three federal programs offer lower down payments and more flexible credit standards.
FHA One-Time Close
FHA construction loans allow down payments as low as 3.5% for borrowers with credit scores of 580 or higher. The minimum qualifying score is technically 500 with 10% down, though most FHA lenders set their own floor around 620 to 640. The loan closes once and covers the land (if you still need to buy it), construction, and permanent financing. You will pay FHA mortgage insurance premiums for the life of the loan, which adds to the monthly cost.
VA Construction Loans
Veterans and eligible service members can build on their own land with no down payment and no private mortgage insurance. The VA requires proof of income, reserves, assets, and debts, along with a full credit check. The program takes more documentation and pre-planning than a standard VA purchase loan, and the VA will not issue its guaranty until a final compliance inspection confirms the home meets VA minimum property requirements.2VA News. VA Offers Construction Loans for Veterans to Build Their Dream Homes Not every VA lender offers construction loans, so you may need to shop around.
USDA Single-Close Construction
The USDA offers a single-close construction-to-permanent loan for eligible rural properties with no down payment required. You must meet USDA income limits (which vary by county and household size) and build in an area that qualifies as rural under USDA maps. If your land sits in or near a metropolitan area, it likely will not qualify.
Credit, Income, and Debt Requirements
Construction loans carry more risk than finished-home mortgages because the collateral does not fully exist yet. Qualification standards reflect that.
Most conventional lenders want a credit score of at least 680, with some requiring 700 or higher for the best rates. FHA accepts scores down to 580 for 3.5% down. VA has no official minimum, though individual lenders impose their own. Expect construction loan rates to run noticeably higher than traditional mortgage rates during the building phase.
Income documentation is predictable. Lenders want two years of federal tax returns and W-2 statements. Self-employed borrowers provide the same two years of returns plus a year-to-date profit and loss statement and a balance sheet for the business. You will also provide two months of recent bank statements to show liquid reserves for interest payments and surprises during the build.3USDA Rural Development. Chapter 9 Income Analysis
Your debt-to-income ratio matters too. For loans that qualify as General Qualified Mortgages under federal rules, the ratio of total monthly debt to gross monthly income historically could not exceed 43%.4Bureau of Consumer Financial Protection. Qualified Mortgage Definition Under the Truth in Lending Act: Extension of Sunset Date The CFPB has since shifted to a price-based threshold for the General QM definition, but most construction lenders still treat 43% to 45% as a practical ceiling. Coming in well below it strengthens your application.
Getting the Land Ready to Build
Before any lender approves a construction loan, the land has to be buildable. Owning the deed is not enough. The lender wants proof the property is legally and physically ready for a home.
Zoning comes first. Your parcel must be zoned for residential use, and the planned home must comply with local setback requirements, height restrictions, and lot coverage limits. A survey confirms boundary lines, shows easements, and demonstrates that the planned structure fits within setbacks. Professional boundary surveys for residential construction typically run between $1,800 and $6,500 depending on lot size and terrain.
Utility access comes next. Lenders need to know the property can connect to water, sewer, and electricity. If public water and sewer are not available, you will need a well and septic system that meet local health department standards. For FHA loans, wells must deliver at least five gallons per minute over a four-hour period for new construction, and water quality must meet either local health authority standards or EPA National Primary Drinking Water regulations. If utilities are not located on permanently dedicated easements, the lender must confirm that utility access is recorded on the deed.
Permits are the third piece. Fees for new residential construction vary widely but often run $5 to $12 per $1,000 of project value, so a $400,000 build might carry permit fees of $2,000 to $4,800. Some jurisdictions also charge impact fees to cover roads, schools, and other infrastructure for new development. Those can range from nothing to tens of thousands of dollars depending on the municipality.
Builder, Contract, and Budget
Lenders will not fund a construction loan without vetting the builder. Your builder needs to be licensed and insured and able to show financial stability. Expect the lender to require proof of general liability insurance and workers’ compensation coverage, along with references or a track record of completed projects. A history of lawsuits, liens, or bankruptcies will likely sink the application regardless of your personal qualifications.
A fixed-price contract between you and the builder is essentially non-negotiable from the lender’s perspective. It should spell out start and completion dates and include a line-item cost breakdown covering all materials and labor. Any changes after closing require a formal change order that the lender must approve, so getting the contract right at the outset saves real headaches later.
The construction budget needs to be thorough. Lenders want a detailed breakdown of both hard and soft costs:
- Hard costs cover site preparation, foundation, framing, roofing, plumbing, electrical, HVAC, interior finishes, and landscaping.
- Soft costs cover architectural and engineering fees, permits, surveys, insurance premiums, loan origination fees, and interest payments during construction.
Detailed blueprints go with the budget so the appraiser can estimate the future value of the finished home. That “appraised when complete” value determines how much the lender will actually fund. If your budget is $400,000 but the appraiser says the finished home will only be worth $350,000, the lender bases the loan on $350,000 and you cover the gap.
Most lenders also require a contingency reserve of 5% to 10% of the construction budget to cover unexpected costs. It is a formal requirement, not optional padding, and many borrowers overlook it when planning their finances.
Being Your Own Builder
Owner-builder construction loans exist but are genuinely hard to get. Lenders see self-built homes as significantly riskier, and most will only approve borrowers who hold a general contractor’s license and can document prior homebuilding experience. If you have never built a house, this route is essentially closed. The few lenders who do offer owner-builder loans typically require larger down payments (25% or more) and charge higher rates.
Draws, Inspections, and Interest Payments During the Build
A construction loan does not hand you the full amount at closing. The lender releases money in stages called draws, and you pay interest only on what has been disbursed.
A typical draw works like this: the builder completes a phase of construction, say the foundation, then submits a draw request to the lender. The lender sends a third-party inspector to the site to verify the work matches the approved plans. If everything checks out, the lender releases funds for that phase. Inspections typically cost $150 to $250 each and are either deducted from loan proceeds or billed directly to you.
Most construction loans allow four to six draws, though some lenders permit more. A common schedule covers site work and foundation, framing and roofing, mechanical systems, interior finishes, and final completion. You, the builder, and the lender negotiate the exact schedule before closing. Lenders also commonly hold back a portion of each draw, called retainage, of 5% to 10% until the project is fully complete. That money is released after the final inspection. At each draw stage, the title company updates its search to confirm no mechanics’ liens have been filed by subcontractors or suppliers; if a lien shows up, the lender pauses further draws until it is cleared.
Monthly payments during the build cover only interest on funds already drawn. Early on, when little has been disbursed, payments are modest. They grow as more draws are released. On a $300,000 construction loan at 9% interest, after the first $75,000 draw the monthly interest payment would be roughly $563. After the full $300,000 is drawn it climbs to about $2,250. Budget for the worst-case monthly payment so you are not caught off guard.
The construction loan term is typically 12 to 18 months. If building takes longer than expected, you may need to request an extension, which usually involves additional fees. Realistic scheduling at the outset pays off.
Cost Overruns, Change Orders, and Builder Default
This is where construction loans get messy. Material prices move, you decide to upgrade the countertops, or excavation turns up rock that needs blasting. Any deviation from the original budget requires a formal change order that both you and the lender must approve.
Every change order needs documentation: a description of the change, an updated cost estimate, and signatures from you and the builder. The lender reviews each one to confirm the project still makes financial sense at the new price. If cumulative changes push total cost beyond the loan amount, you cover the difference out of pocket.
The contingency reserve is your buffer. A 10% contingency on a $350,000 build gives you $35,000 of breathing room. Without it, even a modest surprise like hitting clay soil or needing upgraded electrical service can stall the project while you scramble for additional funds.
Builder default is the nightmare scenario. If your contractor abandons the project or goes bankrupt mid-build, you are left with a half-finished house and a loan that is still accruing interest. Some lenders require a performance bond, which guarantees the surety company will either complete the project or compensate you if the builder defaults. Performance bonds typically cost 1% to 3% of the contract price. Not all residential lenders require them, but they are worth considering, especially with a builder you have not worked with before.
Converting to the Permanent Mortgage
Once the home is finished and the local municipality issues a Certificate of Occupancy, the construction loan transitions to a permanent mortgage. With a one-time close, that happens automatically under the terms you locked at the original closing. With a two-time close, you go through a second closing with the associated costs.
Before conversion, the lender’s appraiser returns to confirm the home was built according to the original plans and that the completed value supports the permanent loan amount. Fannie Mae requires a completed Appraisal Update and Completion Report (Form 1004D) at this stage.1Fannie Mae. B5-3.1-02, Conversion of Construction-to-Permanent Financing: Single-Closing Transactions If the property value has declined since the original appraisal, the lender may require you to requalify at the new value.
At conversion, interest-only payments end and you begin paying principal and interest on the full balance. The permanent loan term cannot exceed 30 years, not counting the construction period.1Fannie Mae. B5-3.1-02, Conversion of Construction-to-Permanent Financing: Single-Closing Transactions You will swap your builder’s risk insurance policy for a permanent homeowners policy before the lender finalizes the conversion. The title company records the final mortgage deed, and from that point the loan functions like any other 15-year or 30-year fixed-rate mortgage.
Deducting Interest Paid During Construction
The IRS allows you to treat a home under construction as a qualified home for purposes of the mortgage interest deduction, but only for a period of up to 24 months starting on or after the day construction begins. If the home becomes your qualified residence once it is ready for occupancy, the interest you paid during those 24 months of construction is deductible.5Internal Revenue Service. Publication 936, Home Mortgage Interest Deduction
There is a timing wrinkle. If you take out the permanent mortgage within 90 days after construction is completed, deductible home acquisition debt is limited to expenses incurred within the 24 months before work was completed and ending on the date of the mortgage.5Internal Revenue Service. Publication 936, Home Mortgage Interest Deduction Staying within the 24-month construction window protects the deduction. If your build drags past that period, you lose the ability to deduct interest on the portion of time that exceeds it.
Expect a property tax reassessment once the home is complete. Most jurisdictions reassess based on the value of the finished structure, which will be far higher than the value of raw land. Timing and method vary by locality, but the tax increase is coming and should figure into your post-construction budget.
