Since the bank failed to maintain the property and allowed low income families to occupy this once luxury property.

I would then demand that money and if she fails to produce it I would sue her. 

I should have been clearer, the $17k fee is the interest rate differential calculated by the bank. 

PMI, sure, why not, i would try to include it in their payments, just like the banks do.

All I need is 3 months business bank statements and a simple one page application.

I've been trying to find ways to contact the owner or find the bank that may own them to try and get the house but have been unsuccessful.

Who do you know who would like better than-than-market returns on their investments and/or better-than-bank returns on their savings?

It also tracks your expenses and income, either by snapping a picture of a receipt or by linking your bank information/credit cards and importing the data.

Does the court need a probate referee, if the house in the estate is a shortsale and bank does their own appraisal?

@Barri GriffithsNegotiating a price on a short sale is more about who's willing to fight for it; having comps and learning to use deviation is great, but if you go in with just data, hoping the bank will see things your way, you've already lost.
