I don't understand your point at all. What's an absentee landlord in your book? A landlord who doesn't live in the place they are renting out? I would assume that's - all of them?
A non absentee landlord lives on the same land as the rental unit.
Clearly that's not what the GP means, because there would be no dilemma with someone living in a property held by a landlord for more than 30 days if the absentee landlord can just live next door.
Do you mean a contiguous, legal parcel of land or a more natural division, like valleys, mountaintops, coastlines, etc.?
