It is now the “hyperinflation” of housing prices: economics
Some friends bought the second house and didn’t even sell their first house… They didn’t buy it as a hedge. One is a home improvement designer who wanted to do something during the epidemic, so he bought a house to decorate. The other wanted a swimming pool, but didn’t actually build it, but didn’t like the house where she lived, so she only bought a third house. The other temporarily moved out of SF Express, and is now selling the house she bought, preparing to move back in late summer. I think this is a bit like Nintendo Switch purchase or ground swimming pool purchase, except that this is something the upper class purchases.
Due to the suspension, no one I know rents out their second house now, which is of no avail.
