Welcome to East Portland, home of the $300,000 house.

The neighborhoods east of Interstate 205 are the only parts of the city where the average purchase price remains less than $300,000, according to Portland Housing Bureau data.

But in the past three years, two Portland neighborhoods surrounding 82nd Avenue saw median home sale prices cross the $300,000 threshold.

As measured by the rest of Portland, that's a bargain—after all, the median selling price for a home in this city in 2016 was $381,108.

But home prices have increased even faster on the outer eastside than in the city as a whole.

The $300,000 sales price is a benchmark, because the average Portland household can make mortgage payments for a $300,000 home without spending more than 30 percent of their monthly income.

City-compiled statistics lag behind privately published data, but they give a clearer picture of how home values change from year to year.

That leaves just six places in the city where the average family can afford a house. (The Lents and Foster neighborhoods, which in 2016 saw the city's biggest increase in home prices, are now perched on the brink: The median sale price there is $299,000.)
