Understanding Construction Loans

Construction loans provide financing for building new homes or major renovations. Unlike traditional mortgages, construction loans disburse funds gradually as work progresses, with interest-only payments during the construction phase.

How Construction Loans Work

Construction loans are short-term loans (typically 6-18 months) that convert to permanent mortgages once construction is complete. Funds are released in draws based on construction progress, ensuring lenders that money is used appropriately.

Interest-Only Payments

During construction, borrowers pay only interest on the amount of money that has been drawn. This makes construction loans more affordable during the building phase when no principal payments are required.

Draw Process

Funds are released in stages based on completed work. Each draw requires inspection by the lender or a third-party inspector to verify that work meets construction standards and loan requirements.

Construction-to-Permanent Conversion

Most construction loans convert to permanent mortgages at the end of the construction period. The permanent loan may have a different interest rate and terms than the construction loan.

Cost Considerations

Construction loans typically cost more than traditional mortgages due to higher interest rates and fees. Additional costs include construction appraisals, permits, and inspection fees.

Tip: Construction loans require careful planning and a reliable contractor. Always include a contingency budget for unexpected costs. Work with lenders experienced in construction financing for the best terms and process guidance.
