What is a Construction-to-Permanent Loan?
A construction-to-permanent loan is a financing product that combines a short-term construction loan and a long-term mortgage into a single closing, allowing business owners to fund the building phase of a commercial property and then automatically convert that debt into a permanent mortgage once construction is complete. According to the SBA, construction-related financing accounts for a significant share of commercial real estate lending, with the SBA 504 loan program alone funding billions in fixed-asset projects annually.
How a Construction-to-Permanent Loan Works in Business Lending
During the construction phase, the lender disburses funds in draws — incremental payments released as verified milestones are reached, such as foundation completion, framing, and final inspection. Interest accrues only on the amount drawn, not the full loan balance, which helps manage cash flow during the build. Most lenders require a minimum down payment of 10% to 30% of the total project cost, and the construction period typically lasts 12 to 18 months. Lenders will scrutinize the borrower’s creditworthiness, the contractor’s licensing and track record, detailed construction plans, and a certified appraisal of the completed property’s projected value. Per the Federal Reserve’s 2023 Small Business Credit Survey, tightening credit standards have made documentation requirements increasingly rigorous, particularly for construction and real estate projects. The loan-to-value ratio on the permanent phase generally must not exceed 80%, though SBA-backed structures may allow up to 90% financing in qualifying cases.
How this loan type is structured varies significantly depending on the lender. SBA 504 loans are one of the most popular vehicles for construction-to-permanent financing among small businesses, pairing a Certified Development Company (CDC) loan covering 40% of the project with a conventional bank loan covering 50%, leaving the borrower responsible for just 10% down. Traditional community banks and regional banks also offer proprietary construction-to-permanent products but typically require stronger financials, a minimum credit score of 680 or higher, and a two-year operating history. Online lenders and alternative lenders rarely offer true construction-to-permanent products given the complexity and risk involved, though some CDFIs (Community Development Financial Institutions) serve underbanked borrowers pursuing construction projects in low-to-moderate income areas with more flexible underwriting standards.
What Business Owners Should Do About a Construction-to-Permanent Loan
Before applying, business owners should assemble a complete project package: architectural drawings, a licensed general contractor’s bid, a construction timeline, a detailed project budget, and two to three years of business and personal tax returns. Lenders will also want to see a pro forma income statement demonstrating that the completed property will generate sufficient revenue or cost savings to service the debt. If your personal credit score is below 680, take three to six months to pay down revolving balances and resolve any derogatory marks before submitting an application. Timing matters — lenders prefer applications submitted well before a construction start date, ideally 60 to 90 days in advance, to allow for underwriting, appraisal, and title work. If your project qualifies as owner-occupied commercial real estate at 51% or more, you may be eligible for the SBA 504 program, which offers below-market fixed rates on the CDC portion of the financing and terms up to 25 years on the permanent mortgage.
Navigating construction-to-permanent financing is complex, and the wrong lender match can cost months of lost time or result in a project being underfunded. We connect you with lenders — we do not lend — which means our role is to match your specific project profile, credit background, and financing need with SBA lenders, community banks, and CDFIs best positioned to approve and close your construction-to-permanent loan efficiently. Our matching process considers your loan size, geography, borrower profile, and construction timeline to surface the most relevant options available to you.
What credit score do lenders require for a construction-to-permanent loan?
SBA 504 lenders generally look for a minimum personal credit score of 680, though some CDFIs will work with scores as low as 620 for mission-driven projects in underserved communities. Conventional community banks and regional banks typically require a credit score of 700 or higher, along with a debt service coverage ratio (DSCR) of at least 1.25x. The stronger your credit profile and the more detailed your project documentation, the better your chances of securing favorable terms on both the construction and permanent phases.
How does a construction-to-permanent loan affect my interest rate?
During the construction phase, rates are usually variable and tied to the prime rate or SOFR, often ranging from prime plus 1% to prime plus 3% depending on borrower risk. Once the loan converts to the permanent phase, borrowers may lock into a fixed rate — SBA 504 permanent rates are set monthly by the SBA and have historically run 0.5% to 1.5% below comparable conventional commercial mortgage rates. Improving your credit score from 660 to 720 before applying can meaningfully reduce the spread a lender charges, potentially saving tens of thousands of USD in interest over a 20- or 25-year permanent term.
Can I get a construction-to-permanent loan with poor credit?
Getting approved with poor credit is difficult but not impossible — CDFIs and nonprofit lenders sometimes offer construction financing to borrowers with scores below 640, particularly for projects that create jobs or serve low-income communities. The CDFI Fund, administered by the U.S. Treasury, certifies hundreds of mission-driven lenders nationwide who operate with more flexible underwriting than conventional banks. Alternatively, some borrowers pursue an SBA 7(a) loan for construction costs when the
