And they've priced the homes they are selling quite a bit below what they bought them for already. Many aren't moving too.
I'm not too sure why they just don't hold onto the homes though. Even with the carrying costs, holding on would be profitable if market is to rise another 10%+ as some are predicting. The only reasonable explanation to me is that they are expecting a significant drop in 2022-2023, but maybe I'm wrong.
