Construction Loans: Going From Land You Own to a Finished House

Most land buyers are really house buyers who started early. The parcel is step one. The harder question comes later: how do you pay for a house on land that no bank will treat as a finished home?

The answer is a construction loan, and it works differently from both a land loan and a mortgage. Money goes out in pieces as the house goes up. The rate usually floats. An inspector visits before each payment. And the land you already own can stand in for some or all of the cash down payment.

How a construction loan works

A construction loan is short-term money to build. The funds sit in escrow and go to the builder in draws as the work is finished. The builder completes a stage, the lender sends an inspector, you sign off, and the lender pays. Bankrate's January 2026 explainer says to expect four to six inspections over a project.

During the build you pay interest only, and only on the money drawn so far. In Bankrate's words, "your lender typically requires interest-only payments on the funds drawn to date during the construction stage." When the house is finished, the loan either converts into a regular mortgage or is paid off by one, depending on the kind of loan you chose.

Single close versus two closings

Fannie Mae, which sets the rules for conforming conventional loans, says in Selling Guide section B5-3.1-01, dated June 4, 2025: "Construction-to-permanent financing can be structured as a transaction with one closing or a transaction with two separate closings."

The single close is simpler. Section B5-3.1-02, dated May 6, 2026, explains why: "Because the loan documents specify the terms of the permanent financing, the construction loan will automatically convert to a permanent long-term mortgage loan upon completion of the construction."

The trade-off is time. The construction period "may have no single period of more than 12 months and the total period may not exceed 18 months", and Fannie Mae says exceptions will not be granted. A builder who falls behind can push you past that limit, so the start and finish dates in the contract matter. A build that could run longer belongs in a two-closing deal, which section B5-3.1-03, dated August 7, 2019, describes as "two separate loan closings with two separate sets of legal documents".

How land you already own is treated

You must hold title, but a land loan is fine

Fannie Mae's rule: "The borrower must hold title to the lot, which may have been previously acquired or be purchased as part of the transaction."

If you own the lot before the first draw, Fannie Mae treats a single-close loan as a limited cash-out refinance: "The borrower is using the proceeds from the construction financing to pay off any existing liens on the lot and finance the construction of the property." Your land loan is paid off from the new loan. One limit applies. Cash-out refinances are not eligible for single-close construction-to-permanent loans, so you cannot pull extra cash out of the land equity at that closing.

Why land equity acts like a down payment

Fannie Mae does not call this a down payment. It defines the loan-to-value ratio, and that is where the equity shows up. When you are the owner of record of the lot at the first draw, the lender divides the loan amount by the "as completed" appraised value of "the property (the lot and improvements)."

Notice what is missing: what you paid for the land. If the finished house and lot appraise well above the loan amount, that gap is your equity, and it does the job a cash down payment normally does. If you are buying the lot in the same deal, Fannie Mae uses the lesser of the purchase price or the as-completed value, so an appraisal above your costs does not help.

FHA counts land by how long you have owned it

In HUD Handbook 4000.1, for land not yet purchased, or owned six months or less at case number assignment, FHA uses "the lesser of the cost of the land or appraised value of the land". For land owned more than six months, FHA uses the appraised value. FHA also lets land equity cover its 3.5 percent Minimum Required Investment: "The Borrower may utilize any cash investment in the Acquisition Cost of the Property or land equity to satisfy the Minimum Required Investment (MRI)".

VA and USDA also pay the land cost or the land loan balance at closing, and USDA sizes the loan on appraised value. See land loan requirements for how lenders judge the land itself.

Government construction programs

FHA construction-to-permanent

HUD Handbook 4000.1, in the edition issued August 12, 2026, describes it this way: "The CP program combines the features of a construction loan with that of a traditional long-term permanent residential Mortgage using a single mortgage closing prior to the start of construction." In brief, FHA requires:

• A licensed general contractor. "The Borrower may act as the general contractor, only if the Borrower is also a licensed general contractor."
• Written draw approvals. After land costs are paid at closing, the balance goes into escrow, and "The Mortgagee must obtain the Borrower's written authorization for each draw prior to disbursing funds to the contractor."
• The new-construction file. This includes "form HUD-92541, Builder's Certification of Plans, Specifications, and Site", a warranty of completion on form HUD-92544, required inspections, a well water analysis, and a septic report where the local jurisdiction requires one.

VA construction loans

VA's Buyer's Guide, version April 2022, says construction loans close before construction starts, with proceeds covering the cost to build and the land, "with the remaining balance in escrow, sometimes referred to as a Loan in Process (LIP) account, or a Draw account." You can build on land you already own, the lender needs your written approval before each draw, and the first principal payment may be postponed up to one year. VA also says not all lenders are willing or able to offer construction loans, so expect to shop.

USDA single-close construction

USDA's guaranteed combination construction-to-permanent loan is governed by 7 CFR 3555.105. The loan closes before construction, pays the land cost or land loan balance, and escrows the rest. "The borrower and lender are jointly responsible for approving disbursements during the construction phase." The builder needs two or more years of experience building similar single-family homes, any state-required license, and "Insurance for commercial general liability of at least $500,000". The regulation adds: "Contractors or builders who are constructing their own residence are ineligible."

USDA's fact sheet, as of April 2026, states: "Interest rates are fixed at loan closing before construction begins. The appraised value will determine the maximum loan amount." The program is limited to eligible rural areas with populations up to 35,000.

What the lender will ask for

A construction lender underwrites three things: you, the builder, and the plan. NerdWallet's guide, updated August 26, 2026, lists what a lender may request at preapproval: the builder's work history and proof of insurance, plus "blueprints, specifications, a materials list, a detailed budget and a signed construction contract that includes start and finish dates."

In practice:

• An approved builder with a license, insurance, and a track record.
• Plans and specifications. The appraiser values the house from these. Fannie Mae calls the result the "as completed" appraised value and requires the appraisal's effective date to fall within four months of the note date, so finish the plans before you order it.
• A detailed budget, line by line.
• A contingency reserve. USDA lets the loan include "contingency reserves, not exceeding a percentage specified by the Agency of the cost of construction", and NerdWallet lists contingency reserves among the costs a construction loan can fund.
• Permits, fees, and soft costs. USDA's financeable costs include architectural and engineering fees, permits, surveys, title updates, draw control and inspection fees, builder's risk insurance, and landscaping.

Rates, terms, and costs as of October 2026

Freddie Mac's weekly survey reported that "The 30-year fixed-rate mortgage averaged 7.40% as of October 8, 2026, up from last week when it averaged 7.28%." The 15-year averaged 6.73 percent. Both move weekly.

Construction-phase rates run higher. Bankrate's January 2026 explainer says construction loans usually carry variable rates tied to the prime rate and are "typically higher than traditional 30-year mortgage rates by about a percentage point."

Bankrate's worked example: a $50,000 lot and a $350,000 build total $400,000. "Construction-to-permanent loans typically require a 20 percent down payment, which would be $80,000 in this case, and leave you with a $320,000 loan." At a 7 percent rate that is about $2,129 a month. As an illustration under Fannie Mae's as-completed formula, if you already owned that lot free and clear and the finished property appraised at $400,000, the land equity would cover $50,000 of the $80,000, leaving $30,000 in cash.

On timing, Bankrate says "The construction phase typically lasts about one year", and Fannie Mae's single-close cap is 18 months. The land loan calculator shows what a loan amount costs per month at different rates and terms.

What goes wrong

Cost overruns

Bankrate's April 2026 guide is blunt: if building expenses exceed the loan amount, which it says is common, you cover the difference. The contingency reserve exists for this, so resist spending it on upgrades. If the overrun is documented, Fannie Mae allows one fix before conversion: "Increases to the loan amount are permitted only as necessary to cover documented increased costs of construction of the property."

Appraisal gaps and change orders

The original appraisal was done from plans. At completion, Fannie Mae requires Form 1004D, an appraisal update and completion report. "If the appraiser indicates on the Form 1004d that the property value has declined, then the lender must obtain a new appraisal for the property and requalify the borrower using the updated LTV ratio". A finished house worth less than expected means a higher ratio, and possibly more cash or a fresh qualification.

Mid-build upgrades are where gaps are born. VA's Buyer's Guide puts the rule plainly: "Any change order or upgrade made after the appraisal cannot be mortgaged into the new loan unless the appraisal is updated. Change orders must be approved, in advance, by the appraiser, to ensure there is no loss in value." You may pay for them out of pocket. VA states this in its alteration and repair section, but the lesson travels: pick your finishes before the appraisal.

Owner-builder loans and why most lenders refuse them

State law often lets you act as your own general contractor. Lenders mostly do not. Bankrate: "Lenders typically allow this option only if the borrower is a licensed builder by trade." FHA allows it only if the borrower is a licensed general contractor, and USDA makes contractors building their own residence ineligible outright.

The state exemptions cover the permit, not the loan. Florida exempts owners "acting as their own contractor and providing direct, onsite supervision themselves of all work not performed by licensed contractors" when building a one- or two-family residence for their own use and not for sale or lease, and selling or leasing within one year of completion creates a presumption the home was built for sale or lease. North Carolina's law, which applies to projects of $40,000 or more, exempts an owner building on their own land when "the building is intended solely for occupancy by that person and his family", with a 12-month occupancy test after completion.

Neither statute obligates a bank to lend. Owner-builder exemptions and construction contracts carry legal obligations, so confirm the rules with a licensed attorney in your state before you sign a permit application or a builder contract.

Prepare the land first

A parcel that has cleared the usual due diligence is easier to finance, because the budget has fewer unknowns.

• Legal access. FHA's minimum property requirements define adequate access as "an all-weather road surface over which emergency and typical passenger vehicles can pass at all times", from a public street or a private street protected by a permanent recorded easement. See landlocked property and legal access and easements explained.
• Septic approval. Lenders expect septic approval before closing; FHA's new-construction file requires a septic report where the local jurisdiction demands one. See perc tests and septic system costs.
• Water and power. Written estimates for a well and for running electricity to the parcel turn the budget's largest guesses into numbers. Start with what utilities are available.
• Zoning, flood zone, and boundaries. Confirm a house is allowed where you plan it with the zoning guide, check the flood zone, and get a current survey.
• Site work. Clearing, grading, and the driveway belong in the budget, not the contingency. See land clearing costs and what it costs to develop raw land.

If you have not bought yet, the land due diligence checklist and the free printable checklist cover all of this.

The bottom line

A construction loan is a mortgage that pays out in pieces, with an inspector between you and each piece. If you already own the lot, the lender values the finished property, land included, and that is how land equity becomes the down payment. FHA, VA, and USDA all back a single-close version: FHA requires a licensed general contractor, USDA an experienced and state-licensed builder, and VA a builder who meets state and local licensing rules. Prepare the parcel, budget a real contingency, pick upgrades before the appraisal, and keep rate quotes dated, because as of October 2026 they move every week.
