Construction Loans on Land You Already Own: How Your Lot Counts

A builder who already owns the lot tends to ask the same question first: does the land count toward the loan? The arithmetic says it can. A construction loan is sized as a share of the total project cost, and the lot is part of that cost, so land you own outright is equity already in the deal. How much it counts for is where the answers diverge, because 3 different numbers describe the same piece of ground: what you paid for it, what it appraises for today, and what the lender will credit.

This guide is for building to sell or to rent, the business-purpose side of construction lending. A home you will live in is financed differently. The Census Bureau counts houses built on the owner's land for the owner's own occupancy as "contractor-built", and 131,000 of them were started in 2025 at a median contract price of $404K. A spec house or a build-to-rent house on your lot is a business project, and it is underwritten like one.

A lot you own outright is equity already in the deal

Construction lenders size the loan by loan-to-cost (LTC): the loan divided by the total project cost. Total project cost is the land plus everything it takes to finish the house: hard costs for labor and materials, soft costs such as plans, engineering, permits, impact fees and builder's risk insurance, a contingency, and the interest and fees the loan itself will charge. Whatever the loan does not cover is the borrower's equity.

On a purchase, the borrower funds that equity in cash at closing. On land you own, the lot is already in the project, so its value fills part or all of the equity line before you write a check. Here is a spec house on a lot worth $150K, owned free and clear:

    A[Lot value<br/>$150K] --> C[Total project cost<br/>$800K]
    B[Build, soft costs,<br/>contingency, interest<br/>$650K] --> C
    C --> D[Loan at 80% LTC<br/>$640K]
    C --> E[Equity required<br/>$160K]
    A --> F[Land credit<br/>$150K]
    E --> G[Cash to bring<br/>$10K]
    F --> G

The house is 2,500 square feet at $200 per square foot of hard cost, or $500K. That is close to the Census Bureau's 2025 national average contract price of $198 per square foot for contractor-built homes, which excludes the lot; the median was $172. Soft costs add $50K, a 10% contingency adds $50K, and origination plus interest add about $50K, for a total project cost of about $800K.

The leverage a lender offers changes the answer more than anything else:

At 90% LTC the lot covers the equity requirement with $70K to spare, but the house only needs $651K of loan to finish. A loan larger than the remaining cost would be cash out of the land, and whether any lender will advance that surplus at closing is a policy question for that lender. The safer budget assumes the land covers equity and produces no cash.

The interest line assumes a 9.50% rate, 9 monthly draws and a sale in month 12, with interest charged only on funds drawn. Lenders differ on that last point: some charge interest on the full loan from closing, so ask which method a quote uses before comparing them. The construction loan calculator runs the same arithmetic on your numbers; for a lot you own, enter its current value in the land line.

Ask which value the lender credits: the appraisal or what you paid

A construction appraisal usually reports the land's value as it stands and the property's value as completed under the plans and specifications. The question for an owned lot is whether the lender credits that appraised land value or your original cost.

Fannie Mae's construction-to-permanent rules show the 2 measures side by side. When the borrower owns the lot of record at the first advance of construction financing, the loan is measured against the "as completed" appraised value of the lot and improvements. When the lot is bought as part of the same transaction, the loan is measured against the lesser of the total cost, lot price plus construction, or that appraised value. Those rules govern homes people will live in, and business-purpose lenders write their own. The useful question for any lender is which of the 2 measures it applies to your lot, and whether the answer changes with how long you have owned it.

The gap can be large. A lot bought for $90K in 2021 that appraises at $150K today carries $60K of equity that exists only if the lender credits appraised value. Bring the closing statement from your purchase, the appraisal if you have one, and any receipts for work already done on the land, such as surveys, clearing, utility taps or engineering.

Land alone is thin collateral, which is why the construction loan carries the lot

Federal banking regulators publish supervisory loan-to-value limits for real estate loans in the Interagency Guidelines for Real Estate Lending. They set 65% for raw land, 75% for land development and 85% for 1- to 4-family residential construction. A bare lot is the weakest collateral on that list; a lot with a house going up on it is among the strongest.

That is the logic behind land equity. Once construction is financed, the lender's collateral is the lot and the house together, which is why the value you already hold in the ground becomes part of the project's equity rather than a separate asset.

A land loan still on the lot is paid off at closing

A construction lender needs the first lien on the property, so any loan still recorded against the lot is normally paid off from the construction loan at closing. Your equity credit becomes the lot's value minus that payoff.

In the 80% LTC example, a $60K balance on the lot changes the math this way: the lot still counts at $150K in the project cost, the payoff takes $60K of the loan on day 1, and the equity credit falls to $90K. Cash to bring rises from $10K to about $70K, and interest on the $60K runs from closing rather than from the first draw. Order a payoff letter early; it is one of the documents that sets the closing date.

The lot has to be titled in the borrowing entity before closing

A business-purpose construction loan is made to an entity, and the collateral has to belong to the borrower. Sphinx Capital's construction program lends to business entities and trusts, so a lot held in your own name is deeded to the borrowing LLC or trust before the loan closes. Plan that deed with the title company insuring the loan, so the transfer, any payoff and the new lien are reviewed together, and ask whether your state charges a transfer tax or recording fee on the deed.

The entity also decides how the loan is treated. Federal truth-in-lending rules exempt credit extended primarily for business purposes, as the Consumer Financial Protection Bureau's official interpretation of Regulation Z explains, and a house built to sell or rent through an LLC is that kind of project. The rehab loan guide for property you already own covers the same distinction for renovation.

Land equity covers the equity line, not the cash you spend before the first draw

A lot worth more than the equity requirement still leaves bills that land cannot pay:

• Costs paid before closing. Plans, engineering, surveys, soil tests and permit fees are often spent months before a loan closes. They belong in the budget, and lenders differ on whether they credit them as equity or reimburse them at closing.
• Closing costs. The 2% origination fee in the example is financed inside the budget, but title insurance, recording, the appraisal and the lender's inspection fees still need cash at closing; the closing cost breakdown walks through the lines.
• Builder's risk insurance. Many lenders want the policy bound at closing, before the first draw.
• Overruns. Contingency is part of the budget, and lenders generally want to see cash in the bank beyond the equity requirement, because overruns are the borrower's to fund.

Draws release money for work already completed, so the builder has to carry each stage until the inspection clears. The ground-up draw schedule guide shows how that cycle runs.

Keep the lot untouched until the loan records

On land you already own, the temptation is to start: clear the lot, pour a pad, have block delivered. In some states, including these 3, that early work can put a contractor's lien ahead of the construction loan.

• Texas: a mechanic's lien dates from the commencement of work or delivery of materials visible on the land, and a mortgage already recorded at that moment keeps its priority (Property Code §53.123, §53.124).
• Arizona: liens are preferred to encumbrances attaching after labor or materials began, except a construction lender's deed of trust recorded "within ten days after labor was commenced" (A.R.S. §33-992).
• Florida: a Notice of Commencement must be recorded before construction funds go to the contractor, and liens take priority from its recording, which is why the mortgage is recorded first. The Florida construction guide covers the sequence.

A lender asked to finance a site where work has already started has to sort out who is owed what before it can close. Keep the site quiet until the loan records, then start.

A spec house is underwritten on its sale

The lender's exit is the borrower's exit: the house sells, or it refinances into a long-term rental loan. For a spec build, the appraisal's as-completed value and the local market for new homes decide how comfortable that exit looks, and many lenders cap the loan at a share of the as-completed value as well as the cost.

Finished new houses are taking longer to sell nationally. The Census Bureau's new residential sales report for September 2026 counted 111,000 completed new houses for sale, down from 122,000 a year earlier, and the median completed house had been on the market for 3.0 months, up from 2.4 months. The median new house sold for $400,400, 3.9% below September 2025, and the supply of new houses for sale stood at 8.4 months at the current sales pace.

Those months are carry. Once the example loan is fully drawn at about $640K, each month the finished house waits for a buyer costs about $5,070 in interest at 9.50%, before property taxes, insurance and utilities. 3 months on the market add roughly $15K. Put the listing period in the budget at the local pace, not the hopeful one, and decide in advance whether the house rents if it does not sell.

What Sphinx Capital publishes for construction

Sphinx Capital's published construction terms run from $500K to $50M+ at 75% to 90% of cost, with fixed interest-only rates from 9.50%, a typical 2% origination fee and 12 to 36 month terms. The program lends to business entities and trusts, makes non-recourse available, charges no prepayment penalties and lists a 640 minimum FICO, in primary and secondary markets nationwide. The $500K floor fits a project like the example, where the loan needed is $598K to $651K. The construction loan guide covers the program and the full document list.

What to send for a construction loan on land you own

The owned-land file replaces the purchase contract with proof of what you own, what you owe and what you will build:

• Recorded deed or vesting, and the deed into the borrowing entity if the lot is still in your name
• A payoff letter for any loan on the lot, or confirmation it is free and clear
• The closing statement from your purchase of the lot, and receipts for work already done on it
• A survey and any soil, utility or septic reports
• Plans and specifications, with permit status and any impact fees assessed
• A line-item budget with contingency, signed by the builder
• The builder's contract, license and insurance
• A builder's risk insurance quote
• Comparable sales of new homes, or projected rent if the house will be held
• Entity documents: articles, operating agreement, EIN letter and good standing
• Bank statements showing cash for closing and reserves beyond the equity requirement

A lot that arrives with its title, payoff and budget settled lets a lender show you exactly what your land counts for, and that is the file to put in front of us.
