Oregon Mortgage Calculator
Oregon's effective property tax rate (~0.87%) is below the national average — but Measure 50 limits mean bills stay low even as Portland-area values rise.
Oregon's Measure 50 (1997) caps annual assessed-value growth at 3%, keeping effective property-tax rates near 0.87% even as Portland-area median values exceed $500,000. Wildfire risk in southern Oregon and earthquake exposure on the coast are the main insurance considerations. Oregon buyers typically use conventional conforming; FHA is common for first-time buyers statewide.

How Mortgage Calculations Work
Loan Amount
We calculate the principal by subtracting your down payment from the home price.
Monthly Payment
Using the loan amount, interest rate, and term, we calculate your fixed monthly payment.
Amortization
Each payment is split between principal and interest, with early payments going more toward interest.
What factors affect your mortgage payment?
- Home Price: The total purchase price of your property
- Down Payment: Large down payments reduce your loan amount and monthly payment
- Interest Rate: Higher rates mean higher monthly payments and more total interest
- Loan Term: Longer terms have lower monthly payments but more total interest
