All great advice here. I would start with something already built, 10 years old or newer, at least 1500-2000 sq/ft, decent lot 3/4-1 acre and definetely a detached garage if you're going to work on cars in it. My first house and only house, I bought last year in November for $135,000. All brick, built in 1975 (a bit old, but it works), fireplace, central heating and air, 1700sq/ft, .94 acre, detached 2 car garage, brick storage shed and it's in generally good shape. I've had to strip out the master bathroom because whoever built the master bedroom addon screwed up the plumbing and the floors rotter through. but all is good, it's got new floors new plumbing and gett a full face lift inside.
One thing I didn't see mentioned was always check the age of the roof. If it hasn't had new shingles in the last 8-10 years put it in the bid that you want the roof redone. Most of them good for 15-20 years, but don't take that chance.
