In Washington, homeowners spend an average of $1,459 per month on a mortgage payment. You can reduce your home mortgage payments in Washington with these tips.

  • Choose a less expensive house to purchase. The lower the cost of your home, the less you have to pay back monthly on a loan.
  • Extend your loan term. While you could end up paying more in total interest, you have a lower monthly mortgage payment if you choose a, for example, 30-year loan over a 15-year loan.
  • Increase the down payment. The more money you put down on a home, the less you borrow overall, leading to a lower monthly payment.
