I wouldn't try to stir the pot (so that you don't have any plumbing issues when they leave). 

Any suggestions on ways to sweeten the pot for her?  

Seems perfect to me for growing pot.    

NYC is tough to start out, but if you can get a up and coming area thats close to the train lines and less than 40 minutes from the city you might hit the jack pot.

The power of BRRRR, when done right, is to take the same pot of money and use it over and over again to build a portfolio. 

Essentially using 1 pot of money to purchase several homes with. 

But our growth is built on more than just pot.

Ask around your local REIA and find an attorney that has worked these titles pot-tax sale.  

Once I bought one that broke even and went with the equity building routine and most of mine actually beat that bench mark by a nice margin.Josh C. is right, fly over country has this around nearly every corner and that's one thing about why it's so wonderful living out here!!!

If your cash out of the building is 1.3 times the mortgage payment, you should be fine (that is what they call the Cash to Debt ratio), assuming that you own this in your name or you co-sign the note with the owning LLC, your income will sweeten the pot for the bank, if you have a ratio of 1.3 or above and the bank says no to an 75% LTV ratio, go to another bank.
