Why Removing Houses from inactive is NOT a solution.

Being able to pay rent for an extended amount of time in advance would help. As long as the fee is trivial enough, owners are reimbursed their house's value, and the time you can pay ahead is capped at like a year or something super forgiving I don't see a problem. If you're gone longer than a whole year you're not really active enough to clog up a housing slot, I feel.
