What do you mean by “partial?” Do you mean condominiums, timeshares or fractional ownership in some other form like REITs?

Sorry, wasn't specific - and yeah mostly stuff like Pacaso, timeshares, and REITs all deincentivize the creation of low income housing and decrease affordability. This is mostly a personal view, but second home ownership should come with serious costs.
