People will buy the house for sale. The country made it clear that half of the population is happy with one of the sides. Reds want to move out of blue states all the same. So yes, a down payment and a moving rental are a magnitude of order apart, but relocating still introduces huge expenses. A 600 mile trip with a 15' truck and car trailer is about $1,000 (it's the mileage rate that gets you). Hotels if needed, road food, security down payments, and gas are the easy ones to point out. Then there's the added stress and costs of scoping out your destination, finding a suitable place, not being employed during the transition, losing your current social networks, and pulling it off solo. My point is that "just move" isn't feasible to many of the people most affected by the predicted changes.
