They will give you a call to discuss and answer any preliminary questions which will be helpful so you don't waste either of your's time if it's not a match, if it looks like a potential match then they will email you the two items I referenced above.

Are you holding a large deposit to keep him from leaving without notice?

If the investment return matches your objectives, than I would absolutely consider it.

Seller agreed in principal had his attorney review the P&S (same on @Justin Silverio  uses) and told him not to sign it.  2 objections the low initial deposit.. that's no big deal.  

Unless a customer maintains substantial deposits, nearly every commercial bank charges fees to customers to open checking accounts. 

I emailed the poster to try and work out a "deal" to meet him at the property to give him a "deposit" then have him nabbed by the Sheriffs office.

If so, does your employer offer to match your retirement fund contributions?  

Today was a great day, I got my first deposit from my first rental unit.  

Other things to check include: was the notice of sale properly published, are there any federal tax liens, are there any liens which survive the foreclosure(in my county people borrow money from the utility company to put in a heat pump and they put a lien on your house, those liens survive the foreclosure), did they file a substitute trustee, did all parties sign the previous warranty deed, does the legal description of property match the address, are there any survey issues.

You want to make sure that your investing matches your lifestyle.
