That means that our options are either to let the lease expire naturally, or to evict the tenant for violating the lease for smoking pot inside / covering smoke detectors and risk having them become a tenant at sufferance or destroying the property.

They become this fiend, this villain that could destroy you and is probably the hardest phase of all the phases.It is during the MOVING PHASE, that you must be cool, have all your wits about you and be prepared, yet still be cordial so as not to enrage the monster that seems to be lurking in your Tenant during the MOVING PHASE (as there is NO ANTIDOTE to calm the savage beast once it takes form).

Is there a way we can get them out without them destroying the place?

But my own credit was now destroyed.

If you truly believe your tenant won't destroy the house then there's hope.

I have thought about off campus property but dont want them to destroy it

At least she destroyed her grill in the process.....

But I think you will probably find a few that are fine with them as long as the HOA costs don't destroy the cash flow potential.

There will always be new tenants, so don't worry about the turnover, there won't be any turnover if your rental is destroyed beyond repair. 

I’d do cash for keys in this case :Tell them that you are supposed to give them 60 day notice ..and if they don’t destroy the building and agree to vacate before lease is up ..you’ll give them their full deposit back plus additional 100 bucks ( or whatever you’d want to add to entice them ) if they are making things really bad for your good tenant then the good tenant probably won’t be there much longer either if you don’t do something
