Portland mortgage calculator
A median-priced Portland, OR home at 6.75% over 30 years, with Oregon property tax of 0.93% and $1,100 a year of homeowners insurance. Every figure below is computed on our amortising engine — nothing is estimated in the browser.
$4,131 a month, all in
Principal and interest are $3,356; escrow and PMI add the rest. Over the full term the loan costs $690,838 in interest. Discounted at 5%, buying here has a net present value of $19,854 ($359,088 in today’s dollars).
Within Oregon, Portland is 2nd of the 4 Oregon markets covered here, between Bend at the top and Salem at the bottom of a 1.76x spread. A state-level median hides most of that.
The price-to-rent ratio here is 21.0 ($575,000 to buy, $2,280 a month to rent), which is high. Renting and investing the deposit is a genuine alternative in Portland, not a fallback position.
Portland carries a premium over the rest of Oregon: a median home here runs $575,000, about 15% above the state median of $500,000. The deposit moves with it, so the same 20% down is $115,000 rather than $100,000.

Where these numbers come from
Oregon medians come from editorial and are refreshed weekly. The Portland figures index those state medians to the local market, so they track the same feed rather than going stale. Insurance and the state income tax rate are editorial. Treat everything here as a planning estimate, not a quote.
