PORTLAND, Ore. — Home purchase prices in Portland dropped for the first time in seven years, but what about the rental market?

The average rent price in Portland went down 0.5 percent from December 2018 to January 2019, which Daniel Iles of Rent Cafe referred to as a "normal seasonal lull." Over the past year, though, average rent prices in Portland have gone up, with prices in Portland rising 2.5 percent to $1,483.

Portland falls just below the national average rent of $1,420 per month. That number stayed flat over the past month, but since January 2018, prices have gone up $45, a 3.3 percent increase, according to data compiled by Yardi Matrix.

As a large city, Portland is following the national trend for rent prices, though it's worse elsewhere, like in Las Vegas (8.3 percent year-over-year increase); Phoenix (+7.6 percent); San Diego (+6.4 percent); Nashville (+6.2 percent); and Los Angeles (+6.0 percent).

Of the country's 250 largest cities, 93 percent saw rent go up over the past year. Five percent stayed stagnant and only 2 percent saw prices go down.

In Oregon, the largest year-over-year rent increase was in Salem, with rent going up 5.5 percent, followed by 5.1 and 4.4 percent increases in Gresham and Eugene.

Nadalie Balint of Rent Cafe said she expects rent prices to continue to increase this year. 

"Several factors, including higher interest rates and rising home prices, could suggest that residential rents will continue to experience growth in 2019," she said.
