If there was fraud even worse.

Basically there are two types of mortgage loan fraud - fraud for property and fraud for profit.

Was there fraud in her probate filing?

This listing is one of four studios at the same property so I have the luxury of A/B testing Each unit is identical and each listing is almost the same except for reviews (this listing was my "medium" review listing at the property) I increased the ADR to reflect the cost of cleaning so we'll see what happens! 

The fact is that equity skimming is a type of real estate fraud and is a crime.

In 2008 I sold a property then in 2013 sold the identical property next door. 

If you know the proceeds are being reported to the IRS, you are not participating in a fraud scheme. 

I was wondering -- if I used credit, or a third party like PayPal, could I not file a fraud report and reverse the payment? 

Just guessing but the following may apply, Consumer fraud, breaking and entering, wire fraud, misrepresentation & since you'd have to turn on the utilities and show proof of ownership or a lease agreement to do that, there could be additional fraud charges.I had a couple of gals sent to jail when I found out they broke into my property and occupied and had a forged lease agreement.

(If you committed fraud, that doesn't apply.)
