How to check out potential partner

[Sherry Norman]

I'm in negotiations with a bank to buy a multi-family REO property in NJ. If we reach an agreement on the price, I will be seeking a partner who is able to fund the deal in return for interest and equity. Let's be honest here, and I hope I'm not offending anyone, but I encounter a lot of newbies, scammers and BS artists in the RE investment arena. (You know it's true.)

So how should I check out anyone responding to my ad or post looking to partner with me?  I'm trying to avoid the time wasters and wannabes who aren't going to be able to come up with the funding but somehow are hoping they will get the funds together somehow.  Meantime, I could end up losing my deposit due to not being able to close on time.

Suggestions?
