I need to know if this is possible as I know they are in violation of the lease and would like to have proof when I go to file with the court for eviction. 

Squatters will also move in these homes and you will have to evict them through the court as if they were real tenants. 

If he does sue you, give him the balance as you will lose in court.

I had a case where the guest was lying on a few matters, number of guests, Italians declaring as residents of California, of course first time bookers, profile pic being a cartoon, Italian passport name don't match the guest , etc...

I just told the tenant that we got a default judgement and he claims he now needs to 'talk to the court'. 

She doesn’t want to continue with probate attorney anymore now that all court stuff is done it’s a matter of reaching a deal with the kids now.

Then I’d probably show up in court, document in hand just to waste your time.

I just finished purchasing my next project at the court house steps and will get started with the rehab soon.

But, make sure you're tenants are aware that if an eviction is pursued and ends up in court, it will ruin their tenant history and show and eviction--even if they win in the end.

.* for market rate tenants, if someone does not pay the rent, your only options are evictions and then small claim court to try to recoup any money lost.
