The problem is more than interest rates though, it's about the widespread housing shortages around the country. If you sell your house and get a nice little return on it, that probably won't be enough to get you into another comparable place. My mom's neighbor's house just sold for nearly $900k (in Southern CA). This young couple wanted to be closer to work, so they sold their place, and the only comparable they could find was something they got for just over $1 million. It's a crazy real estate world out there.
That is EXACTLY why we purchased a property in 2021, after not having one for many years. It was terrifying not having a place we could go and feel at home. We squeezed in right before interest rates went up.
The Pandemic may have influenced the latest poll. Many fulltimers found themselves with nowhere to stay when the government shut down recreational facilities nationwide including most campgrounds. My lot in the Pahrump co-op saved me from a similar fate when "two weeks to slow the surge" stretched into several months of a total shutdown. Having a place where I could go and ride out the closures was priceless.
