Frequently Asked Questions

How do construction loans work?
Construction loans are short-term loans that fund building a home. You pay interest-only on funds drawn during construction. Once complete, the loan converts to a permanent mortgage or you refinance.
What is average draw in construction loans?
Funds are disbursed in stages as construction progresses. On average, about 60% of the loan is outstanding during construction, so interest costs are estimated on that average balance.
What down payment is needed?
Construction loans typically require 20-25% down payment. Some lenders may require more depending on the project scope and borrower qualifications.
