BEND, Ore. (AP) — Housing prices in central Oregon have increased due in part to the growing price of lumber, The Bend Bulletin reported.

Average home prices in Bend are up 5.7% to about $475,000 compared to this time last year, according to data compiled by Zillow. In Redmond, Oregon, the average price of homes has increased 6.3% to about $340,000.

Demand for lumber increased substantially after widespread stay-at-home orders implemented as a result of the coronavirus pandemic have increased the number of home projects, The Bulletin reported. The price has more than doubled this year, said the National Association of Home Builders.

As demand for lumber increased, production from mills across the country dipped with labor and social-distancing requirements slowing production.

Lumber is one of the key components of home building.

“Nobody could foresee the explosion of demand from DIY projects during quarantine, and I think people were also surprised by a resilient market for new housing,” said Nick Smith, spokesman for the American Forest Resource Council. “Now both producers and buyers are scrambling to meet the demand.”

A one thousand foot board of lumber costs more than $800 today compared to pre-pandemic costs of $300. That price increase is adding between $15,000 and $20,000 to the average costs of houses, said Ryan Jennings, operations and purchasing director for Hayden Homes.
