> I think local municipalities should enact speculator taxes, for anyone who owns an unoccupied property that was not recently inherited. Maybe you get 18 months after your parents die to either sell their home, or take on a tenant.

I'd actually agree with this, with the addition of "or appeal as to why you can't". 18 months seems like a long time, but there are many situations where you just can't get something settled in that amount of time.
