Too many factors involved with that. What is your market like? How far are you willing to travel for a cheaper market? What's your credit like - are you going to pay cash or take out a loan? Do you need PMI if you cannot afford the down payment?

My biggest piece of advise is find a mentor who is NOT on the message boards - seriously, chances are the guy you are flying with next week is doing some sort of real estate investment. Find one who is willing to talk about it and give you advice and is open to help mentor you - not a lot just some one you can ask questions of.

People I found are far more informative and helpful than books and interwebs.
