he is basically a criminal..

The criminals sent an email disguised as title company to my agent asking buyer information, also in the email, forward some trivial information to me.

After the list of offenses I feel I do not have to do the 30 day notice.

After some research, it seems, there is nothing illegal about it, as long as there is not active knocking/engaging with the home owner, as well as staying away from communities whos HOA has a no trespassing signI get them all the time at my house, but they are usually for restaurants, which isn't offensive at all, which is why people probably won't complain and much as "I would like to help you sell your house if your house, etc"If anyone has any advice or knowledge about possible fines associated with this it would be much appreciated. 

@Nancy Sathre-Vogel Sorry to hear about this unfortunate event.This person is criminal.

If we create our procedure now, then should we be okay to let everyone know of the max 3 occupant rule or do we need go through work history, then credit and criminal background checks first?

Please take no offense to what I say here, I say this only as a fellow investor and someone trying to help.  

If they owe money and do not pay they are criminals in my book and I treat them accordingly.To simply decide it will not pay off and therefor is not worth seeking justice is a defeatist attitude.

Almost half of my portfolio has Section 8 tenants in it and as non section 8 people move out i try to move in more Section 8 tenants but i make sure my property manager screens them THOROUGHLY....not with just what's on paper regarding credit report, income and past criminal activity (If any).....I make sure my PM screens to make sure they have no pets, no evictions, no smoking OF ANY KIND and no felonies and we still get TONS of people calling...the biggest problem becomes picking someone from who is left.   

If they ask for it to be in your name, don't rent to them.Do a credit check and a criminal record check.
