This is the most insane and offensive post I've ever seen on BP.Hope you enjoy your time on your local TV stations investigative reports of the landlord who discriminates on weight.

@Adam Rothweiler Sounds like your making the transition from SFR to commercial so the likely 1st purchase would be a smaller building that will likely attract mom & pop businesses.Most folks don't go from SFR to a plaza with a grocery store as the anchor.When you are screening the mom & pop businesses there is no reason not to run a credit and criminal check on the owners themselves. 

I get one low life after another with evictions, criminal histories, low income but thinks they can afford it (75% of income on rent), they are going to pay the landlord who evicted them from their first apartment three years ago back even though I have had all this time to do it and still haven't, he evicted them after their first month it wasn't their fault, I'm innocent, blah bla blah. 

It has no windows and no secondary emergency exit and is uninsurable in it's present condition.If there were a fire now and they were killed,the previous owner could be sued and maybe jailed for negligent homicide.Demanding and accepting one penny from them would make you criminally liable as well.You need to get them out asap and not accept any money from them.Don't give them anymore grief and be helpful finding them somewhere else to go.

How do you go about doing a criminal background check?

I explained that the new roommate would have to apply ($30) as we needed to do a criminal background check.  

Saw the documents in the house that this person is a criminal, has been in Jail in Louisiana and has been doing illegal business and sale stolen cars. 

Be sure to look at past evictions, credit, and criminal for every applicant.  

Was the seller represented by a Real estate broker .. as we don't use attorneys in CA very often for these vanilla deals.If she let some wholesaler type person talk her into this then she is totally screwed.take no offense but non licensed wholesalers are very very dangerous for most folks to deal with as they don't know enough about real estate ( most being new) and or they are only out for themselves and could care less about the seller..

In America, small business is being increasingly looked upon as a criminal behavior by both the public and governments and our society is extremely litigious.
