Earlier quoted context omitted.
Housing is fungible and substitutable. Especially in a WFH world. Ergo building in FL or TX can reduce prices in CA. Why do you think the northeast and CA are losing population?
If housing is fungible I've got a house in Gary, IN to sell to you. WFH makes it possible.
Aside from the snark, I'll make it clear. If you have 100 people and even just 5 of them prioritize LCOL to their current locale, those 5 moving away will reduce demand for the area, regardless if the other 95 would never move to Gary, IN in a million years. Housing is not a closed system, and building nice developments in Raleigh or Denver will take population from higher COL places in the aggregate. Which is exactly why we see population loss in HCOL areas.
Very small brained thinking in the residential real estate world unfortunately.
