I received an offer that is substantially higher than my asking price from a retail buyer, but the buyer would have a mortgage and need a warranty deed.My attorney reviewed the title search and the county's notifications to lienholders and doesn't see any issues. 

We waited 7 months for the bank to make a decision on the short sale, and once the bank came back with an acceptance counter-offer, our buyer bailed, even after multiple times of telling him this was a really good deal!

Hi Brennan, A private loan might be a better option in this situation because it offers a clear and fixed return for your partner, making it a more straightforward investment with predictable income. 

It also comes with an offer to buy the property in 90 days for that same 75% figure.

Home depot offers zero interest for two months.

Two years ago they were offering me a competitive rate however after one year they raised the rates quite a bit. 

Ideally I would want PM to find a new tenant for me but this has been really frustrating to the point that I am considering moving back so I don't lose too much money or get into any legal trouble in the process. 

I have experienced cash flow anywhere from 10-18% with so much more to offer.

I'd love to take you up on that offer and pick your brain a bit.

It's a legal issue determined by your state's laws, so you may want to consult with a landlord-tenant attorney to get a good understanding of that before you make a claim on the deposit.
