How does Oregon's Measure 50 affect property taxes for new buyers?
Oregon's Measure 50 (1997) limits annual increases in assessed value to 3%, using a "Measure 50 assessed value" that is typically well below market value. When a property is sold, the assessed value does NOT reset to the purchase price — unlike California's Prop 13. This means new buyers in Oregon often benefit from continued low assessed values, keeping property taxes relatively modest even in appreciating markets.
Is earthquake insurance important for Oregon homebuyers?
Oregon faces significant earthquake risk from the Cascadia Subduction Zone — a major fault capable of producing a magnitude 8–9 earthquake along the entire coast. Standard homeowners insurance does not cover earthquake damage. The Oregon Department of Insurance can help you find earthquake coverage. Buyers in coastal and Willamette Valley communities should seriously consider earthquake insurance.
What does PITI mean and why does it matter in Multnomah County?
PITI stands for Principal, Interest, Taxes, and Insurance — the four components of a full monthly mortgage payment. Lenders qualify you based on your total PITI payment, not just principal and interest. In Multnomah County, property taxes and insurance can add hundreds of dollars per month to your P&I payment, so it's essential to use a calculator that includes all four components.
What credit score do I need to buy a home in Multnomah County?
Most conventional lenders require a minimum 620 credit score, though the best rates go to borrowers with 740+. FHA loans allow scores as low as 580 with 3.5% down, or 500–579 with 10% down. VA loans have no official minimum but most lenders want 580–620. Your credit score affects both loan eligibility and the interest rate you receive — a difference of 50–100 points can change your rate by 0.25–0.75%.
