A two-close construction loan finances a new home in two separate transactions: a short-term construction loan that pays for the build, and a permanent mortgage that closes after the house is finished and pays off the construction debt. Each loan has its own promissory note, its own underwriting, and its own closing costs, so you go through credit approval twice. The tradeoff for the extra paperwork is timing flexibility. You shop for your permanent mortgage rate near the end of construction, not months before the foundation is poured.
When a Two-Close Structure Makes Sense
The alternative is a single-close (or construction-to-permanent) loan, which combines both phases into one transaction with one set of closing fees. Fannie Mae puts hard limits on that option: no single construction period can exceed 12 months, and the total build cannot run longer than 18 months. Projects that go beyond those windows must be structured as two closings.1Fannie Mae. Conversion of Construction-to-Permanent Financing: Single-Closing Transactions
Single-close loans also lock down what can change during the build. Only the interest rate, loan amount, loan term, and amortization type can be modified. Any other change in the loan terms forces the transaction into a two-closing structure.1Fannie Mae. Conversion of Construction-to-Permanent Financing: Single-Closing Transactions That matters if your project is complex enough that the scope or financing might evolve.
The rate question is the other driver. With a single-close loan, you lock the permanent rate before the first shovel hits dirt. With a two-close loan, you wait until the house is nearly done and shop the market for whatever is available then. In a falling-rate environment, that timing can save real money. In a rising-rate environment, it can cost you. Borrowers who expect rates to stay flat or fall, or who want the widest choice of permanent lenders, tend to favor two closings.
What a Two-Close Loan Costs
The biggest upfront number is the down payment. Most lenders require at least 20% of the appraised value of the finished home, not just the cost to build it. On a projected $500,000 finished value, that’s $100,000 or more. Lenders may ask for a higher share from borrowers with thinner credit files.
Construction loan rates run higher than standard mortgage rates because the lender is carrying more risk. Late 2025 into 2026, most construction loans sit in the 6% to 8% range, though credit score, down payment, and each lender’s appetite for construction risk move the number. You pay interest only on the amount drawn, so monthly costs stay modest early and climb as more money is released.
The defining cost of this structure is paying closing fees twice. Each closing typically runs 2% to 5% of the loan amount, covering title insurance, recording fees, appraisal, and origination. On a $400,000 loan, that’s roughly $8,000 to $20,000 per closing. The combined burden over both transactions can be meaningfully higher than a single-close loan, so build it into your comparison.
Most lenders also require a contingency reserve of 5% to 10% of the construction budget, built into the loan itself. It’s not money you lose. It sits in the loan as a buffer for cost overruns, material price spikes, or scope changes, and any unused portion reduces your outstanding balance when the construction loan is paid off. Skipping or underfunding the contingency is where projects run into trouble, because any overage beyond the approved loan amount comes out of your pocket.
How the Construction Phase Works
Draws and Lien Waivers
The lender does not release the full loan on day one. Money comes out in stages, typically five to seven draws, as the builder hits milestones: foundation, framing, roofing, rough mechanicals (electrical, plumbing, HVAC), interior finishes, and final completion. Before each payment, the builder submits a draw request documenting the work performed and costs incurred.
With each request, the builder must provide lien waivers from subcontractors and material suppliers confirming they’ve been paid for the prior phase. These waivers are critical. Without them, unpaid workers or suppliers can file mechanic’s liens against the property, which cloud title and can derail the permanent loan. Most lenders will not release the next draw until all prior waivers are in hand.
Inspections and Retainage
Before each draw, the lender sends a third-party inspector to confirm the claimed work is actually done and meets professional standards. Inspections typically cost $100 to $300 per visit, charged to the borrower. The inspector is not there to approve finishes; they’re confirming the physical work matches the draw request.
Many lenders also hold back a percentage of each draw, usually 5% to 10%, as retainage. That money stays in reserve until the project reaches substantial completion. Retainage gives the builder a financial incentive to finish every punch-list item and gives the lender a buffer against last-minute disputes. It’s released after the final inspection confirms completion.
Change Orders
Mid-build changes are close to inevitable. You pick different countertops, the engineer finds unexpected soil, or material prices shift. Every change should be documented through a formal change order specifying the modification, the cost impact, and the updated timeline, signed by builder and borrower before new work starts. The lender must also approve any change that affects the total budget, because an increase can push the project past the approved loan amount. Getting that approval before work begins avoids the ugly surprise of paying overages out of pocket.
Interest-Only Payments
During construction, monthly payments are interest-only, calculated on the amount actually drawn rather than the full loan balance. If $80,000 has been disbursed on a $400,000 loan, you owe interest on $80,000. Payments stay relatively low at the start and climb as each draw is released. These payments service the debt but don’t reduce principal.
That matters because many borrowers are also paying rent or a mortgage on their current home during the build. Running two housing payments for 9 to 18 months can strain a healthy budget, so plan for the overlap. Construction loan terms typically run 12 to 18 months, with some lenders allowing up to 24 for larger or more complex projects.
The Biggest Risk: Qualifying Twice
This is where the two-close structure can bite. Because the permanent mortgage is a separate transaction with a new promissory note, the lender underwrites you fresh at the second closing. Fannie Mae is explicit: all standard eligibility and underwriting requirements apply to the permanent financing at the time of the second closing.2Fannie Mae. Conversion of Construction-to-Permanent Financing: Two-Closing Transactions Your credit score, income, debt-to-income ratio, and employment status all get re-evaluated. If anything has deteriorated, you can fail to qualify.
The consequences are serious. You’d have a finished house, a construction loan coming due, and no permanent financing to pay it off. Your options narrow fast: find an alternative lender willing to work with your changed circumstances (likely at a worse rate), request an extension from the construction lender (not guaranteed and not free), or sell the property to repay the construction debt. None of those are pleasant.
To protect yourself, avoid taking on new debt during the build, keep credit utilization low, and don’t change jobs if you can help it. Some borrowers get pre-approved for the permanent mortgage before construction starts, which doesn’t guarantee final approval but confirms the profile is in the right range. The gap between closings is not the time for a new car loan or a career pivot.
The Second Closing
As the build wraps up, the local building department must issue a Certificate of Occupancy confirming the home is safe to live in. That document triggers the permanent financing process. You submit an updated financial package, and the lender orders a final appraisal to confirm the home was built to plan and holds its projected value.
Proceeds from the new mortgage pay off the outstanding construction loan balance in full. Once that debt is satisfied, the lender records a satisfaction of mortgage or reconveyance to release the initial lien from the property’s title.3Fannie Mae. Satisfying the Mortgage Loan and Releasing the Lien Fannie Mae treats the permanent loan in a two-closing transaction as either a limited cash-out refinance or a cash-out refinance, depending on how proceeds are handled.2Fannie Mae. Conversion of Construction-to-Permanent Financing: Two-Closing Transactions
The second closing has its own costs: updated title search, title insurance on the new loan, recording fees, and origination. You then begin standard principal-and-interest payments on whatever product you’ve chosen, typically a 30-year or 15-year fixed-rate mortgage. The transition from Certificate of Occupancy to permanent closing usually takes 30 to 45 days, so plan for at least one more month of interest-only construction payments after the house is technically finished.
Deducting Construction Loan Interest
Interest paid on a construction loan may be deductible as home mortgage interest, but only under specific conditions. The IRS lets you treat a home under construction as a qualified home for up to 24 months, starting any time on or after the day construction begins. The home must actually become your qualified home when it’s ready for occupancy. If the project stalls indefinitely or you never move in, the deduction doesn’t apply.4Internal Revenue Service. Publication 936, Home Mortgage Interest Deduction
The deduction is also subject to the overall cap on mortgage debt. For loans originating after December 15, 2017, the Tax Cuts and Jobs Act capped deductible mortgage debt at $750,000. That cap was scheduled to expire after 2025, which would return the limit to $1,000,000 for 2026.5Office of the Law Revision Counsel. 26 USC 163 – Interest Check IRS Publication 936 for the current limit in effect when you file, since congressional action may change the threshold. If your combined construction loan and permanent mortgage exceed the applicable limit, only interest on the portion within the cap is deductible.
Keep detailed records of every interest payment during construction, including the dates and amounts of each draw, so your preparer can calculate the deduction accurately. The 24-month clock matters: interest paid past that window may not qualify.
