Property Scam - Please be careful

There is currently a group of people "buying" property who are running a scam, we are not sure what the final result of the scam is because we have been fortunate to smell a rat before they could complete the con.

The people we have dealt with are all foreign males but I'm sure that they come in all shapes and sizes. They approach us with a cash offer on a house, they seem to be very keen buyers not bothering to negotiate. They then insist on getting a copy of the offer to purchase but are not prepared to hand over their FICA documents or they supply forged letters.

Please be very careful, we are not sure why they are doing this! It seems the big thing is getting the offer.
