A listed Single Family Home is actually a 2-Flat

[Atul Mohlajee]

I looked at a 2 Story Single family home in a Chicago Western suburb but it is actually a 2-Flat.  There is kitchen on each floor and separate entrance and exit doors to both floors.  It shows up as a Single Family Home on all websites.  Did any one had that kind of experience?  Please respond as I am looking insight into what to do?  Price and condition of home are very good and I am interested in buying this because actually I like a 2-Flat better anyway for 2 rents obviously as a Buy and Hold.
