Even filing the mortgage at the county courthouse has a cost. 

First they should review the mortgage contract to see whether there is a due on sale (transfer) clause, or whether the loan can be assumed.Second, if the gift the land to you, there may be potential gift tax filings for the parents.

You need separate bank accounts, checkbooks, annual filings, etc.

They had a text convo To which the leasee provided to me via screen shot, “ I cannot be evicted, and the credit that is on file is the one that will be damaged not mine!

But you may file the eviction complaint. 

Otherwise you would need 2 years of tax filings.

Once you start getting those you need to file form d's, which cost around another $2,000.5.

I would imagine that many red states would be the ones filing the lawsuits.I do agree that the bleed from the states like CA's laws are a danger for many other places. 

If I had a chance to read the filings I very well might change my mind.

Once the taxes are filed and accepted, it's too late.
