You want the dispute history and paper trail to point only toward her. 

It took me 15 minutes to file online, it was an easy one as I had an appraisal from Oct last year but 6 hours after I turned in the protest they returned their resolution.

If you get caught up in a legal dispute involving multiple defendants and your exposure is minimal or even nonexistent, plaintiffs and some judges are going to frame the case to target you instead of the responsible party because you are the one with the deep pockets.

Everyone said due to all the disputes, there would never be an agreement to sell and disperse. 

The relatively inexpensive cost of the appliance does not justify the possible maintenance responsibilities or the chance of creating tenant disputes.

You have a dispute with the prior sellerYour dispute with the seller regarding appliances, you most likely are wasting your time, you will spend more in legal fees than you will cost of the appliances.

This fact alone disputes everything claimed by HVA franchisees.  

I'd recommend having a professional dispute it (like Texas Tax Protest or one of the other companies listed here).

If I were going to own one, that would be a good neighborhood for it.I didn't feel it was dangerous but I decided it wouldn't be much fun to wring cash from the tenants every week or turn up to sort out drunken disputes at 2am.But, no doubt there's a lot of money to be made, especially if you don't plan to declare cash income on your taxes.
