How it works
Buying a median-priced home in Portland. At $550,000 with a 20% down payment, you'd bring $110,000 to closing (plus closing costs) and take out a $440,000 mortgage. At a 6.50% interest rate on a 30-year fixed loan, your monthly principal + interest is roughly $2,781.
Annual costs on top of the loan. Oregon's average property tax rate is 0.93%, so a median-priced Portland home generates approximately $5,115 in annual property tax (about $426/mo when paid through escrow). Homeowner's insurance in Oregon averages around $800/year.
Total monthly payment (PITI) on the median Portland home works out to about $3,274 per month at current rates, assuming a 20% down payment and no HOA. If you're putting less than 20% down, add PMI to this — typically 0.5–1.5% of the loan balance per year.
Rates change; this is the math, not the offer. Mortgage rates fluctuate daily. Our default of 6.50% is a recent conventional 30-year benchmark — enter today's quoted rate from your lender for the most accurate payment estimate.
