His suggestion was to wholesale it because he believed that for the purchase price of $90K, it'd be a relatively safe bet with a good margin.So, my question is: How do I get cash buyers or "buyers lists"?

A local broker will be your best bet. 

The best bet is to talk to a small local bank (or three) about your options.

Your best bet is to invest in growing areas that are landlord friendly and where you can either connect with or build a good team yourself- realtor, property managment, contractors, etc. 

The best bet is to ask a local landlord attorney what is and isn't allowed in your area. 

Your best bet at this point is to get together with an architect and see what your options are.

I bet you will get 75% higher response to your e-mails.Would love to hear everyones thoughts on this.

There are several great ones in Dallas, but I'll bet these days most want you to have some skin in the game, so no 100% financing and also financing of renovation costs. 

Sorry to be bearer of bad news but your best bet is to just get it resolved and take it as a lesson learned

As the other post suggests selling and investing the money till I can find a turn key property sounds like the safest bet.
