Found a deal- not sure what to do next!

[James Phillips]

So I found a deal on craigslist for a home, seems too good and I"m not sure where to go from here.

Based on the address and MLS the property was purchased in 2011 for about $200K. It apparently was listed in October for $180,000, and was under contract for $165K earlier this month but I guess it didn't go through. Now its listed for $156K.

One home is being listed for $230K, other homes have sold in the neighborhood for above $200K.  

It honestly seems too good to be true and I'm not sure what the next step is.  I've done some research, have the number for the (former?) listing agent, and the owners number.  

To me, it seems like this is either a pig-in-a-poke or unbelievable luck.  Any advise is appreciated!
