You want to inflict a level of pain for them to continue to occupy *your* house once you've sold it that will encourage them to go - unless, of course, the objective is to maintain them as a long-term tenant.

I believe SFH will feel some pressure but not MF, unless it is self inflicted. 

I was too young to be fully involved invested, but I was old enough to see the damage it inflicted and the lives it crushed.

It's so terrible to say, and I get that not everyone can pull themselves up by their boot straps but damn, so much is self inflicted.

If they attack, they have the physically capability to inflict 10x the damage compared to an  "average" dog of the same size.

@Lucas Carl the urban progressives are never content unless inflicting their "progress" upon everyone, everywhere.

That said you haven't lost out on any rent yet she's late not delinquent.She has a life threatening ailment that she didn't bring upon herself.You have a self-inflicted problem - you took out a mortgage that you don't seem to be able to afford without rent.She should do whatever she needs to do to survive.

If you get on their bad side from the start, even if you prevail, they could just sit and wait, and inflict financial pain on you later on.

I would also assume property damage is at least equal or higher than comparable units however couldn't the leases have the Parents of the renters be liable for any damages their little darlings would inflict?

Your job, as you see it, is to inflict pain and to "know the pain tolerance of each owner" so they say "ouch!"
