Feasible? Legal? Beneficial?

Still seeing posts on other boards about distant investors asking about the condition and livability of specific neighborhoods. I don't live in town anymore and never will again, but this concept still annoys me and personifies the term 'slumlord' to an extent. To me distant landlords have little, if any incentive to maintain properties short of collecting rent. Just the bare minimum, nothing more and sometimes not even that. They don't really care who lives there or how they get along with any neighbors.

Would it work to require rental property owners to also live in the city? To be a part of the community? For properties of four units or more, could they be required to live on-site or hire a manager/caretaker to live on-site?

Would it help at all?
