Understanding Interim Construction Loan Interest
When purchasing a pre-sale or under-construction property, buyers often use an interim (or construction) loan to cover staged payments to the developer before the property is completed. During the construction period, you typically make interest-only payments as each installment of funds is drawn.
How Draws Work
Rather than receiving the full loan at once, funds are drawn in installments aligned with construction milestones. Each draw increases your outstanding balance and therefore your monthly interest obligation. Your monthly interest reaches its peak after the final draw.
Interest Calculation
Monthly interest = outstanding balance × annual rate ÷ 12. For example, a $300,000 loan at 7% annual interest means a maximum monthly interest payment of $1,750.
What Happens at Completion
At project completion, you typically pay the final settlement amount and convert the interim loan to a permanent mortgage. Plan ahead by checking available mortgage rates and your borrowing capacity well before the expected completion date.
Frequently Asked Questions
Yes, construction and interim loans typically carry higher interest rates than standard mortgages due to the additional risk and administrative complexity. Rates vary by lender and market conditions.
Some lenders offer construction-to-permanent loan products that lock in your permanent rate at closing. This can protect against rate increases during construction. Ask your lender about available options.
