The median home price in Portland is $489,000, with a local 30-year mortgage rate of 6.8%. A buyer putting 20% down carries a loan of $391,200, generating a monthly P&I payment of $2,550. Adding property taxes ($4/mo) and homeowners insurance ($204/mo) brings total monthly PITI to $2,758.
Portland's property tax rate of 0.0091% is among the lower rates in the country, which improves overall affordability by keeping total PITI closer to the principal and interest payment alone. On the Portland median home, that is $4/month, or $44 per year.
Oregon levies a state income tax, which affects take-home pay and effective buying power. High-income earners in Portland should factor state tax liability into their overall housing budget — mortgage interest may be deductible on both federal and state returns.
