How Mortgage Payments Work in Oregon
A standard mortgage payment in Oregon is calculated using the amortization formula:M = P[r(1+r)^n] / [(1+r)^n - 1]
Where P is the loan principal, r is the monthly interest rate (annual rate ÷ 12), and n is the number of monthly payments. On a $490K home in Oregon with a 12% down payment at 6.82% over 30 years, your principal and interest payment comes to approximately $2,817/month— not including property taxes or homeowner's insurance.
Oregon's property tax rate of 0.97% adds roughly $396/month to your total housing cost on a $490K home. This rate is near the national average of ~1.1%.
