Legal issues buying a foreclosure

[Aditya Mehta]

I am a newbee and am looking to buy a single family home that is up for foreclosure next week.  In looking at the history of the property it appears the property was previously sold in an auction a couple of months ago and that sale was eventually reversed.

Can someone tell me why this would be the case?  Could you also please provide links/ education/ article references to the legal risks in buying foreclosure properties?  The property is in Texas.  Also, if someone could refer a good real estate attorney and a good title company to do a pretitle search, i would greatly appreciate it.

Thanks!
