1. What is a Buydown Mortgage?

A buydown mortgage is a type of financing where the borrower pays an upfront fee to reduce the interest rate on their mortgage for a certain period. This can make initial payments more affordable, particularly helpful for buyers who expect their income to increase over time.

2. How Does the Calculator Work?

The calculator uses the buydown formula:

Where:

• \( \text{Loan} \) — Total loan amount in dollars
• \( \text{Reduction} \) — Desired interest rate reduction percentage
• \( \text{Rate Adjustment} \) — Lender's adjustment factor for buydown calculations

Explanation: The formula calculates the upfront payment required to temporarily reduce the mortgage interest rate.

3. Importance of Buydown Calculation

Details: Accurate buydown cost calculation helps borrowers understand the true cost of temporarily reducing their mortgage rate and compare this option against other mortgage products.

4. Using the Calculator

Tips: Enter the total loan amount in dollars, the desired interest rate reduction percentage, and the lender's rate adjustment factor. All values must be positive numbers.
