I have a proposed solution for affordable housing, make what is essentially a FHA or first time home buyer community. If senior communities are a thing, why not this. For those that don't know FHA loans are for "first home buyers." The loans require that the loan holder lives in the property as their primary residence, and some time frame of not previously owning property, and I think something about length of ownership. To me this is the only rule that needs to be applied. A community with no "investment properties", no "house flipping", and no landlords. A place where everyone owns the place they're living in. Property could still appreciate in value, but just needs to be sold to another "first time home buyer".
