Example Calculation for a $450,000 Home

How Interest Rate Affects Your Mortgage

Interest rate is one of the most important factors in your mortgage. Even a 1% difference can change your monthly payment significantly.

For example:

  • At 5.5% interest → lower monthly payment
  • At 7% interest → noticeably higher payment

This is why it is important to compare lenders and secure the best possible rate.

Why Down Payment Matters

Your down payment directly affects your loan amount. A higher down payment means:

  • Lower monthly payments
  • Less interest paid over time
  • Better loan approval chances

For a $450,000 home:

  • 10% down = $45,000 upfront
  • 20% down = $90,000 upfront (often preferred by lenders)
