How Much Can You Borrow for a Construction Loan?

How much you can borrow for a construction loan comes down to three things: what the finished home will appraise for, what the whole project costs, and how much monthly debt your income can support. The lender looks at all three and uses whichever one produces the smallest number, then checks it against the loan limit for your county and loan type.

That's why two people building the same house can end up with very different loan amounts. Below, we'll walk through each piece so you can estimate your own number before you talk to a lender.

How do lenders decide how much you can borrow to build a house?

With a regular home purchase, the lender looks at the price of a house that already exists. With a construction loan, there's no house yet, so the lender sizes the loan around a few moving parts:

• The total cost to build. Land (if you're buying it), the builder's contract, site work, permits, and fees.
• The as-completed appraisal. An appraiser estimates what the home will be worth once it's finished, based on your plans and specs.
• Your ability to repay. Income, monthly debts, credit, and savings.
• Program loan limits. Conventional, FHA, VA, and jumbo programs each have their own caps.

The loan amount is capped by the lowest of these. A strong income won't help if the appraisal comes in below the project cost, and a high appraisal won't help if your debts are already stretched.

What counts toward your total project cost?

Lenders want to see the full cost of getting to a finished, livable home. A typical project budget includes:

• Land purchase price, if the lot is part of the loan.
• The builder's fixed-price contract, covering the house itself.
• Site work, such as clearing, grading, driveway, well, septic, and utility hookups.
• Permits and plan fees, including architectural or engineering work.
• A contingency reserve, which many lenders require to cover surprises.
• Closing costs and other soft costs, some of which may be financed depending on the program.

Leaving items out of the contract to make the number look smaller usually backfires. Most lenders want everything needed for a certificate of occupancy included up front. Our guide to construction loan scope of work explains how detailed your budget should be.

How does the appraisal affect your loan amount?

The appraisal is often the deciding factor. The appraiser reviews your plans, specs, and lot, then compares them with recent sales of similar homes nearby to estimate the "as-completed" value.

If that value comes in at or above your project cost, you're in good shape. If it comes in lower, the lender will size the loan to the appraised value, and you'll need to cover the gap with cash, land equity, or changes to the plans. Read more in how a construction loan appraisal works.

Custom features that buyers in your area don't usually pay for, like an oversized shop or high-end finishes in a modest neighborhood, can push the cost above what the appraisal supports.

How much does your income and debt matter?

A lot. Lenders look at your debt-to-income ratio (DTI), which compares your total monthly debts, including the future house payment, taxes, and insurance, to your gross monthly income. Each program and lender has its own limits, and stronger credit and savings can give you more room.

To get a realistic number:

• List every monthly debt that shows on your credit report, like car loans, student loans, and card minimums.
• Count only income you can document, usually with W-2s, tax returns, or pay stubs.
• Ask how the lender treats your current home if you'll be paying rent or a mortgage while you build.

Paying down a car loan or a card balance before you apply can raise the amount you qualify for.

Can you use land you already own to borrow more?

Often, yes. If you already own your lot, many lenders let you count its value (or the equity you have in it) toward your side of the deal. That can reduce the cash you need at closing or let a bigger share of the budget go toward the house. How land is valued and credited varies by lender. See using land you own toward a construction loan for the details.

What are the construction loan limits in 2026?

Loan limits depend on the program and your county:

• Conventional (conforming): Limits are set each year by the Federal Housing Finance Agency (FHFA), with higher limits in designated high-cost areas.
• FHA: FHA limits vary by county and are set each year by HUD, with higher limits in high-cost markets.
• VA: VA doesn't cap the loan for Veterans with full entitlement, but lenders set their own maximums for VA construction loans.
• Jumbo: If your project is above conforming limits, a jumbo construction loan may be the fit. Each lender sets its own maximums. Our video How Do Jumbo Construction Loans Work for a Custom Home? explains how they're structured and what lenders look for.

Many construction lenders also have a minimum loan amount, which can matter for smaller builds or projects on land you already own.

Do you borrow the whole amount at once?

No. Even though your loan is approved for the full amount, the money is paid out in stages, called draws, as the builder finishes each phase of work. An inspector usually confirms the progress before each draw is released. Learn more in how construction loan draws work.

How can you estimate your own number?

Before you talk with a lender, pull together:

1. A rough project budget from your builder, including land and site work.
2. Your gross monthly income and every monthly debt payment.
3. Your credit score range and how much you have saved for closing and reserves.
4. What you owe on your land, if you already own it.

A lender can then run the numbers against the appraisal and program rules. Requirements vary by lender, so it's worth comparing more than one.

Frequently asked questions

Is a construction loan amount based on the appraisal or the cost to build?

Both. Lenders generally use the lower of the project cost or the as-completed appraised value, then make sure you qualify for the payment.

Can I include the land in my construction loan?

Usually, yes. Many construction-to-permanent loans can include the lot purchase, or let you use land you already own toward the project.

Can I borrow more than the builder's contract to cover overruns?

Many lenders build a contingency into the loan, but they generally won't lend beyond what the appraisal and your income support. See what happens if your construction loan goes over budget.

Does my credit score change how much I can borrow?

It can. Stronger credit may give you more room on debt-to-income limits and open more programs. See what credit score you need for a construction loan.

Is there a minimum construction loan amount?

Many lenders have one. If your build is small or you own the land outright, check the minimum before you finalize your plans.
