Construction Loans for Spec Builders
Last updated: March 2026
Construction loans provide short-term financing for building new residential properties. They differ from traditional mortgages by disbursing funds in stages through a draw process as construction milestones are completed. These loans are designed for spec builders who build homes for sale rather than for a specific buyer.
How Construction Loans Work
Construction loans fund the building process from ground-up. The lender commits to a total loan amount based on the project's plans, budget, and projected value. Funds are released incrementally through draws as work is completed and verified.
Interest is typically charged only on the amount disbursed, not the full commitment. This keeps costs lower in the early stages of construction when only a portion of the loan has been drawn.
At project completion, the borrower either sells the property and repays the loan or refinances into permanent financing.
The Draw Process
- Builder completes a phase of construction per the schedule of values
- Builder submits a draw request with documentation of completed work
- Lender sends an inspector to verify the work is complete
- Upon verification, lender disburses the draw amount
- Process repeats for each phase until construction is complete
Schedule of Values
A schedule of values is a detailed breakdown of the total construction budget into line items — foundation, framing, mechanical systems, finishes, etc. Each line item has an assigned value that corresponds to a draw milestone. This document is central to the draw process and helps both the builder and lender track project progress and remaining budget.
Builder's Risk Insurance
Builder's risk insurance covers the property during construction against risks such as fire, theft, vandalism, and weather damage. Most construction lenders require this coverage as a condition of the loan. The policy typically covers the structure, materials on site, and materials in transit.
Cost-to-Complete Analysis
Lenders periodically review the remaining budget against remaining work to ensure there are sufficient funds to complete the project. If costs exceed the original budget, the borrower may need to contribute additional equity or adjust the scope.
Interest Reserve
An interest reserve is a portion of the loan set aside to cover interest payments during construction. This allows the builder to avoid making monthly out-of-pocket interest payments while the project is underway. The interest reserve is calculated based on the projected draw schedule and term.
Common Mistakes in Construction Lending
- Underestimating construction costs or timeline
- Inadequate contingency in the construction budget
- Poor draw documentation or incomplete verification
- Not securing permits before closing the loan
- Failing to account for site preparation costs
- Insufficient builder's risk insurance coverage
