- Short-term loan that funds building a home from foundation to finish.
- Typically requires 20%–30% down and a FICO score of 680+. (CFPB data)
- During construction, you pay interest only on money drawn so far.
- Best for borrowers with strong credit, cash reserves, and a licensed builder.
- High-cost and high-complexity option for those who could instead buy an existing home or use a renovation loan.
Ground up construction loans are short-term financing products that pay for building a home from the foundation up, rather than buying an existing property. Unlike a traditional mortgage, the lender disburses funds in stages as construction progresses, and the borrower typically pays interest only on the amount drawn so far. Interest rates on construction loans tend to run 1 to 2 percentage points higher than standard mortgage rates, reflecting the higher risk to the lender.
Building a custom home in 2026 can cost between $300,000 and $600,000 or more depending on location and finishes, but obtaining the right financing is not as simple as getting a regular mortgage. Construction loans come with unique underwriting requirements: lenders evaluate the builder's credentials, the project's architectural plans, and the borrower's ability to carry the eventual mortgage. This article explains how ground up construction loans work, what lenders look for, the costs involved, and the most common ways these loans differ from standard home purchase financing.
1. What Is a Ground Up Construction Loan?
What Is a Ground Up Construction Loan?
A ground up construction loan is a type of short-term financing specifically designed to fund the construction of a new home on a vacant lot. Instead of receiving the full loan amount upfront, the borrower draws money in predetermined installments, called draws, that match each stage of building: foundation, framing, roofing, mechanical systems, and finishing. The lender inspects the property at each stage before releasing the next draw.
During the construction phase, the borrower typically pays interest-only payments based on the amount actually drawn, not the total loan amount. Once construction finishes, usually within 12 to 18 months, the borrower must either pay off the loan in full or convert it into a permanent mortgage. Many lenders offer a construction-to-permanent loan, which rolls the construction financing into a standard 30-year mortgage after the home is completed, avoiding a second closing.
Here is how ground up construction loans differ from standard mortgages:
- Payout structure: Lump sum vs. staged draws tied to construction milestones.
- Interest payments: Interest-only during construction; full principal + interest after conversion.
- Loan term: Short (12–18 months) during construction; 15–30 years after permanent conversion.
- Underwriting focus: Borrower credit plus builder qualifications, plans, budget, and timeline.
According to the Consumer Financial Protection Bureau (CFPB), construction loans represented roughly 6% of all residential lending activity in 2025, a share that has held steady as new-home construction rebounded from post-pandemic lows. A typical 2026 construction loan for a single-family home ranges between $250,000 and $500,000, but amounts vary significantly by region, California and Northeast metros push well above $700,000 in high-cost areas.
2. How Ground Up Construction Loans Work: A Step-by-Step Process
Below is the typical sequence a borrower goes through when obtaining a ground up construction loan in 2026.
- Pre-approval and documentation. The borrower submits financial statements, tax returns, credit history, and debt-to-income information to the lender. The lender also reviews detailed architectural plans, a construction contract with the builder, a line-item budget, and the builder's license and insurance.
- Loan approval and closing. Once approved, the borrower signs the loan documents at closing. At this point, funds are not disbursed, the lender places them into a construction account. The borrower pays closing costs, typically 2% to 5% of the loan amount. Rates and fees were verified on March 2026 and may have changed since.
- Draw schedule and inspections. Construction begins. The builder requests draws at each milestone, foundation pour, framing, drywall, etc. The lender sends an inspector to verify the work before releasing each draw. The borrower pays interest only on the cumulative amount drawn.
- Interest-only payments. Monthly payments cover only the interest accrued on outstanding draws. For example, on a $400,000 loan at 8.5% interest, if the borrower has drawn $200,000, the monthly interest payment is approximately $1,416.
- Completion and conversion or payoff. After final inspection and a certificate of occupancy, the borrower either converts the construction loan into a permanent mortgage (one-time close) or obtains a separate mortgage to pay off the construction loan (two-time close, which may involve additional closing costs).
Most borrowers choose the construction-to-permanent option because it eliminates a second closing with duplicate costs. Lenders who offer this product typically lock the permanent mortgage rate at the initial closing, though some allow a float-down at conversion.

Construction loan rates in 2026 are generally 1 to 2 percentage points higher than conventional 30-year fixed mortgage rates, which averaged approximately 6.7% in February 2026 (Freddie Mac Primary Mortgage Market Survey). That means borrowers can expect rates between 7.7% and 8.7% for a ground up construction loan. These rates are variable, they float with the prime rate or SOFR during construction, so monthly payments can change as the Federal Reserve adjusts its target rate (currently 4.25%–4.50% as of March 2026).
Other costs include:
- Origination fee: Typically 1%–2% of the loan amount.
- Inspection fees: $100–$400 per draw inspection, with 3–6 draws typical.
- Appraisal fee: $500–$800 for the initial appraisal, often required before closing.
- Title and escrow: $1,500–$3,000 depending on location.
Lenders typically require a 20% to 30% down payment for ground up construction loans, higher than the 3–20% for conventional mortgages because the lender has no completed collateral until the project finishes. Self-employed borrowers may need to provide two years of tax returns and a profit-and-loss statement; some lenders also ask for liquidity reserves equal to 6–12 months of interest payments.
| Lender | Rate Type | Down Payment | Max LTV During Construction | Notes |
|---|---|---|---|---|
| Chase | Fixed-rate conversion | 20% | 80% | Construction-to-permanent only; rate lock at closing |
| Wells Fargo | Adjustable during construction | 25% | 75% | Requires builder with 3+ years experience |
| Bank of America | Prime + spread | 20% | 80% | Pre-approval within 30 days |
| Rocket Mortgage | Fixed-rate conversion | 25% | 75% | Online-only process; inspector visited site within 7 days of draw request* |
*as of March 2026. Rates and fees vary by location and are subject to change. APYs are variable and can change at any time without notice.

VIEW CONSTRUCTION LOAN RULES →4. Caveats, Trade-Offs, and Alternatives
Ground up construction loans are not the right fit for every building project. Here are the most important limitations and alternatives borrowers should consider before committing.
Common Limitations
- Higher upfront cost. Down payments of 20%–30% on a $500,000 project mean bringing $100,000–$150,000 to closing, not including land costs if the lot is purchased separately.
- Variable rates. During construction, most loans have floating interest rates. If the Fed raises rates mid-project (as happened in 2023–2024), monthly payments can increase unexpectedly.
- Builder risk. The loan depends on the builder completing the project on time. If the builder goes out of business or abandons the project, the borrower may need to find a new builder and refinance mid-construction, a scenario the CFPB notes can add significant costs and delays.
- Limited lender pool. Not all lenders offer construction loans. Smaller community banks and credit unions are often the best source; national online lenders are more selective.
When This Doesn't Work
Borrowers who plan to act as their own general contractor often face higher interest rates or rejection, lenders prefer a licensed, insured builder with verifiable experience. Self-employed borrowers with irregular income may also struggle to satisfy the stricter debt-to-income requirements. In these situations, a renovation loan (like an FHA 203(k) or a conventional renovation loan) might be a more realistic alternative if a suitable existing home is available.
Alternatives to Ground Up Construction Loans
- Renovation loans (FHA 203k, Fannie Mae HomeStyle). For purchasing and rehabbing an existing home, not for building from scratch.
- Owner-builder construction loans. Some lenders offer these, but they require the borrower to have substantial construction experience and a significantly higher down payment.
- Personal loans. Up to $50,000 (see Personal Loans Up to $50,000), these are unsecured, carry rates above 10% typically, and are unsuitable for large-scale construction, though they could supplement minor finishing work.
Expert Tips
- Get pre-approved before signing a builder contract, a lender's denial mid-project can leave you with a half-built house and no financing.
- Choose a construction-to-permanent loan to avoid paying duplicate closing costs (title, appraisal, origination) at conversion.
- Ask whether the lender allows a rate float-down at conversion, if rates drop during construction, you may be able to lock a lower permanent rate.
- Verify the builder's license, bond status, and insurance through your state contractor licensing board before submitting their contract to your lender.
- Build a contingency fund of 10%–15% of the total project budget to cover change orders, material price increases, or delays, lenders rarely fund overruns beyond the approved budget.
Mistakes to Avoid
- Choosing a lender solely on rate without comparing inspection timelines and draw schedules, some lenders take 7–10 business days to release draws, which can slow construction.
- Assuming a fixed-rate conversion loan locks the permanent rate at the same rate as the construction phase, they are often priced differently.
- Signing a construction contract with a builder before lender approval, which can force you into a cash purchase if financing falls through.
Pros and Cons
👍 Pros
- Interest-only payments keep monthly costs low during construction.
- Construction-to-permanent loans avoid a second close and additional fees.
- Funds are disbursed in stages, protecting the borrower from paying for incomplete work.
👎 Cons
- Higher down payment than a conventional mortgage (20%–30% vs. 3%–20%).
- Variable interest rates during construction create payment uncertainty.
- Not available from all lenders; underwriting is more stringent than standard loans.
Bottom Line
Ground up construction loans are a practical option for borrowers who have substantial savings, a clear building plan, and a licensed builder. They offer more flexibility than paying cash out of pocket but come with higher costs and more complexity than a typical mortgage. For borrowers with strong credit (740+ FICO) and a 20%+ down payment, this can be a workable path to a custom home. Borrowers with limited cash reserves or who need a simpler process should consider renovation loans or buying an existing home instead.
Frequently Asked Questions
No. A construction loan is short-term financing (12–18 months) used to build a home, while a standard mortgage funds the purchase of an already-built property. With a construction loan, the lender disburses money in stages as the builder completes each phase of work. After the home is finished, the borrower can convert the construction loan into a permanent mortgage.
Most lenders require a 20% to 30% down payment on a construction-to-permanent loan. This is higher than the 3% to 20% down payment typical for conventional mortgages because the lender has no finished house as collateral until construction ends. Some portfolio lenders may accept as little as 15% if the borrower has excellent credit and a strong builder.
Lenders generally look for a FICO score of at least 680 for a ground up construction loan, and many prefer 720 or higher. Borrowers with scores below 680 may still qualify at some community banks but will likely face a higher interest rate and a larger down payment requirement.
It is possible but difficult. Most lenders require the builder to be a licensed, insured professional with a proven track record. Owner-builder loans exist but come with stricter terms: a higher down payment (often 30%–40%), a requirement to prove construction experience, and a maximum loan-to-cost ratio below 70%. The CFPB notes that owner-builder projects also carry higher risk of cost overruns.
If the project exceeds the original budget, the borrower must cover the difference in cash. Lenders do not increase the loan amount after closing. If the builder delays beyond the loan's maturity date, the borrower must seek an extension from the lender, which may involve additional fees, rate increases, or refinancing. Building a 10%–15% contingency into the budget is standard advice from the National Association of Home Builders.
