DENVER (KDVR) -- The number of homes for sale in the Denver Metro is up significantly.  A report by Realtor.com shows Denver has the greatest increase in inventory in the country when compared to pre-pandemic levels.

According to the Colorado Association of Realtors, there are about 18,000 homes for sale along the Front Range. Dan and Tristin Gleason's home in Lone Tree is one of them.

"It's been on the market about a month," Dan said. "Certainly it's a little scary knowing there's so much product on the market and so much competition now," he said.

The couple bought a new house in April that needed renovations and kept the Lone Tree home while the work was being done. But now? 

"It's costing us money every day that we don't sell our previous home. So that adds a lot of stress to life, a lot of costs," Dan said.

New construction makes up a big chunk of the local inventory.

"The market is really challenging if you're a seller," said Kelly Moye with the Colorado Association of Realtors.

"We're seeing our average days on the market between 60 and 70 days now to sell. Even just last month, our average days was 40," Moye said.

In addition to the increase in inventory, interest rates, the cost of homeowners insurance and uncertainty over the economy are also making buyers cautious.

"If you're a buyer right now, enjoy it. Enjoy the inventory. Enjoy a little bit longer to think about it. Maybe go back and see it a second time. If you're a seller, price it right. Make it look great. Be patient," Moye said.
