How to finance building a new home

Key takeaways

• New-home financing works differently than buying an existing home. Construction and builder-backed loans are often short-term, higher risk and more complex than traditional mortgages. 
• Affordability matters as much as qualification. Buyers should base their budget on real monthly cash flow — not just what a lender will approve — and plan for cost overruns that are common in new builds. 
• Strong credit and savings are essential. Construction loans generally require excellent credit, a solid down payment and a low debt-to-income ratio to qualify for favorable terms. 

While financing is often discussed throughout the homebuilding process, it’s worth taking a closer look at the options available specifically for new construction.

Building a home is a major undertaking, and financing a new build comes with unique considerations. From construction loans to builder-arranged financing, here’s what to know about paying for your new home.

Building a home is exciting — and expensive. Costs can rise quickly once you start selecting upgrades, finishes and custom features. Buyers should be careful not to stretch their budgets too thin.

Falling behind on mortgage payments can quickly turn a dream project into a financial strain.

Lenders often recommend borrowing no more than about twice your gross annual income. For example, a household earning $200,000 a year may qualify for a $400,000 mortgage. However, that guideline doesn’t account for personal circumstances.

To get a clearer picture, add up your monthly expenses, including debts such as student loans, car payments and credit cards, as well as childcare, utilities and other fixed costs. Subtract those from your monthly income. Then account for everyday spending such as groceries, entertainment and shopping. What remains is the amount you can reasonably apply toward a mortgage and other homeownership costs.

Mortgage calculators, such as the one on Homes.com, can help estimate monthly payments based on interest rates, loan terms and location.

When selecting a floor plan, it’s wise to stay below your maximum budget. Home builds often run about 20% over budget, making conservative planning essential.

Steps to take

• Start with income guidelines: Use the general rule of thumb, borrow no more than about twice your gross annual income, as a starting point, not a limit. 
• Review your full financial picture: List all monthly expenses, including debts, childcare, utilities and other fixed costs. 
• Calculate what’s truly available: Subtract expenses and everyday spending from your monthly income to see what you can realistically put toward a mortgage and homeownership costs. 
• Use a mortgage calculator: Estimate monthly payments based on current interest rates, loan terms and location to stress-test your budget. 
• Build in a buffer: Choose a floor plan and price point below your maximum budget, since new builds often run about 20% over initial estimates. 

The down payment is the upfront payment made when purchasing a home. It’s typically about 20% of the purchase price, though the exact amount depends on the loan type.

Buyers who put down less than 20% usually must pay private mortgage insurance, or PMI. A larger down payment reduces the loan amount and the lender’s risk — an especially important factor for new construction, which is riskier to finance than an existing home.

If you’re working toward a 20% down payment, consider using a high-yield savings account or money market account. Cutting discretionary spending and setting monthly savings goals can help you stay on track. Choose a target date and determine how much you need to save each month.

Construction loans carry more risk for lenders, so strong credit is essential. Before applying, check your credit score and review your credit report for errors. Correct any inaccuracies as soon as possible.

Your debt-to-income ratio also plays a major role in loan approval. Paying down credit cards and other outstanding loans can improve your chances of qualifying and securing a better interest rate.

Construction loans cover the cost of building a home rather than the completed property itself. They may include funding for land, permits, architectural plans, labor and materials.

Because the home doesn’t yet exist as collateral, these loans are harder to obtain than traditional mortgages. They are also short-term, typically lasting six to 12 months. Once construction is complete, the loan either converts into a long-term mortgage or must be paid off.

A construction-only loan is a short-term, adjustable-rate loan used to finance the build. Once construction ends, the borrower must repay the loan in full, often through a balloon payment or by securing a traditional mortgage.

This option works best for buyers with access to significant cash, such as those selling an existing home.

The risk is considerable. If financing falls through or a current home doesn’t sell in time, borrowers could face serious financial pressure. There’s also the risk that the completed home may not appraise for the amount needed to refinance.

A construction-to-permanent loan combines construction financing and a traditional mortgage into a single loan, eliminating the need for two closings.

During construction, borrowers may pay interest only on the funds drawn. Once the home is complete, the loan converts to a standard mortgage.

Because the lender is committing upfront without a completed property as collateral, these loans can be harder to qualify for and may carry higher interest rates.

Some builders — particularly semi-custom and large-scale developers — offer in-house or affiliated financing. These companies may guide buyers through design, construction, financing and closing, functioning as a one-stop shop.

Builder-sponsored financing can come with incentives such as closing-cost assistance, upgrades or pricing discounts. However, there are drawbacks.

Because the builder and lender are affiliated, there may be conflicts of interest, and buyers could face higher interest rates than they would receive from an independent lender.

A bridge loan is another short-term option, typically lasting six months to a year. It helps buyers cover the gap between selling an existing home and purchasing or building a new one.

Bridge loans are secured by the equity in your current home and are commonly used to fund a down payment. They can be difficult to qualify for and often carry higher interest rates than traditional loans.

A progress draw mortgage releases funds in stages as construction reaches specific milestones. The loan is distributed in installments, commonly across four phases: land and foundation, partial completion, substantial completion and final completion.

Before each release, a lender’s inspector reviews the project. If progress or workmanship is unsatisfactory, funding may be delayed or denied.

Because the loan amount is set with the initial draw, upgrades may be limited. Once construction ends, borrowers must secure a traditional mortgage to repay the construction loan.

Some buyers may qualify for government-backed loans, which can offer more flexible terms.

Federal Housing Administration loans are designed for buyers with low to moderate incomes. They typically require a down payment of about 3.5% and are more forgiving of credit challenges.

Borrowers generally need a credit score of at least 580. Those with scores between 500 and 579 may qualify with a 10% down payment. Requirements vary by state.

Waiting periods apply after bankruptcy or foreclosure, and applicants must meet credit and income guidelines.

VA loans are offered through the U.S. Department of Veterans Affairs for eligible veterans and military borrowers. They can be used to buy, build or improve a home.

These loans offer significant benefits, including no down payment, no PMI and competitive interest rates. The VA guarantees a portion of the loan, reducing risk for lenders and allowing for more favorable terms.

Nearly 90% of VA-backed loans are issued with no down payment, though borrowers must work with a VA-approved lender.

With so many financing options available, it’s important to compare loan types, interest rates and terms carefully. Some loans require specific eligibility criteria or government-approved lenders, which can limit options.

Regardless of the loan you choose, shopping around and comparing offers from multiple lenders can help you find the best fit for your financial situation — and your new home.
