What Affects Your Mortgage Payment

  • Interest rate — The single biggest factor. Even a half-point difference means tens of thousands over the life of a 30-year loan. Test different rates.
  • Down payment — Every dollar upfront shrinks the loan — and crossing 20% eliminates PMI. Calculate your PMI.
  • Loan term — 15 years roughly halves total interest but requires a substantially higher monthly payment.
  • Property taxes — Vary widely by state and county. Budget $380–$1,200/month on a $625K home.
  • Homeowners insurance — Typically $245–$500/month. Required by every mortgage lender.
  • Your DTI ratio — Most lenders cap total DTI at 43%. Calculate yours.
