I was probably totally scammed. 

I don't want to get this process wrong, be scammed, or lose out because I did something wrong.After we talked, he texted me and said we can meet tomorrow (today) and get the contract signed and he needs $1500 earnest money deposit (EMD). 

It really comes down to a gut check, and meeting people, looking them in the eye, still is the best way to suss out a true partner vs a scam artist in most cases.

It is most likely a scam.

There are some scam artists in Dallas who were selling properties they didnt own.PLus in a lot of cases the house isnt safe and thats one of the reasons its not being listed on the MLS, as owner guess what, I think you are now liable for the condition of the house.IF we ever did a leaseback, and I probably wouldnt do one with a wholesale deal., I would put a large amount in escrow until they moved out.

@Greg LovernSounds like a scam to me.

With a “poor me” I’m going to be homeless,don’t take my grandmas mistakes out on me” gosh I could go on and on and on.But now I’m back to the what do I do. 5 days up, non pay ( as mentioned, now 3 days later past, she is still trying to scam me to stop the eviction!

They are going to promise the world and it MAY all be a scam.
