Construction loans work differently from standard mortgages. Instead of receiving a lump sum at closing, funds are released in stages as your project hits specific milestones. This structure protects the lender and keeps your project on track financially. Whether you're building from the ground up or doing a major renovation, understanding how these loans work will help you plan better and avoid surprises.
What Is a Construction Loan?
A construction loan is short-term financing designed to cover the cost of building or substantially renovating a property. The loan term typically runs 6 to 18 months, matching the expected construction timeline. During the build, you usually pay interest only on the amount that's been disbursed, not the full loan balance. Once construction is finished, you either pay off the loan, refinance into a permanent mortgage, or sell the property.
Types of Construction Loans
There are three main types to know:
Construction-to-permanent loans start as a construction loan and automatically convert to a mortgage when the build is done. You only go through one closing, which saves on fees.
Construction-only loans cover just the build period. When construction wraps up, you need to pay off the balance through a refinance, sale, or another loan. This option gives you flexibility to shop for the best permanent financing after the project is complete.
Renovation loans are designed for remodeling existing structures. They work on the same draw-based system but are tailored to the scope and timeline of rehab projects rather than new builds.
How the Draw Schedule Works
The draw schedule is the backbone of a construction loan. It maps out when funds will be released based on completed project phases. A typical schedule might include draws for foundation, framing, rough mechanicals (plumbing, electrical, HVAC), drywall, and final finishes.
Before each draw is released, the lender sends an inspector to verify that the work has been completed as planned. This step-by-step process keeps the project accountable and helps prevent cost overruns from spiraling out of control.
What Lenders Want to See
Construction loans are riskier for lenders than standard mortgages because there's no finished property to use as collateral yet. To offset that risk, lenders typically require:
- Detailed architectural plans and specifications
- A comprehensive, line-item budget
- A realistic construction timeline
- Proof that your contractor is licensed, insured, and experienced
- A down payment of 20% to 30%
- Evidence that the finished property's value will justify the total investment
Interest Rates and Costs
Expect construction loan interest rates to run higher than standard mortgage rates. The premium reflects the added risk: there's no finished building to foreclose on if something goes wrong. You'll also pay origination fees and inspection fees throughout the build. Factor all of these into your project budget from the start so there are no surprises at the end.
Plan for the Unexpected
Construction projects rarely go exactly as planned. Weather delays, material shortages, permitting holdups, and subcontractor scheduling conflicts can all push your timeline back. Build a contingency reserve of 10% to 15% into your budget. If you don't need it, that's money back in your pocket. If you do need it, it keeps your project from stalling.
What Happens After Construction
With a construction-to-permanent loan, you transition directly into mortgage payments. With a construction-only loan, you'll need to refinance, sell, or pay off the balance. The right exit strategy depends on whether you're building to hold, building to sell, or building to rent. Have your exit plan in place before you break ground, not after.
Is a Construction Loan Right for Your Project?
Construction loans are the standard tool for funding new builds, major renovations, and ground-up development projects. They require more planning and documentation than a standard mortgage, but they give you access to capital when no finished property exists yet. If you have a solid project plan, a qualified contractor, and a clear exit strategy, a construction loan can turn your project from blueprint to reality.
