When I reached up to them and asked what's going on, they told me that they are lawyers and engineers, and there is a lawsuit against the previous landlord of this property.

We (the homeowners) just won a lawsuit against the builder for construction defects.

Give back the threat to sue them for your interest increase/difference on your transactions due to their unfair credit reporting, if they report it, you could call the bureaus and have it called off, then add that to the lawsuit, hire a credit repair service so you will have a paid invoice transaction. lol, all this for $100.

He had 7 or 8 lawsuits over the past few years.

Have an additional umbrella policy on the property to cover excess liabilities and lawsuits. 2.

There's now a lawsuit from one of the seller's because they were selling to a buyer who then wholesaled it to Zuckerberg at a 1.7 million dollar markup!!!

If he gets caught would it be worth the lawsuit, license loss, fines and destruction of reputation to do it?

The exact wording of your lease on this point could be very important.In Alabama, you cannot file an eviction lawsuit until you have issued the 7-day letter and the tenant does not cure in time.

It is better to pay the $100  for the eviction as opposed to getting a lawsuit.  

He said I don't need to keep them on paper, if I scan them into the computer then delete them after 2 years I'm good.Secondly, he also said to keep a written copy of the tenant screening criteria with the applications, because that may be needed in case of a discrimination lawsuit.
