start watching home and gardening telivision, troll mls daily to get a good understanding of the current market values, make sure that hte house won't make you house poor, you deserve to have extra cash for yourself, equity is important, but quality of life is more important.
when looking at a house
look for water damage, potential water damage, grading around the foundations, smell the basement, get familiar with electrical codes, insulations, windows and different materials all around the house. LOOK can be deceiving. follow your gut, and don't ever fall in love with a house, you can make a stupid deciision this way.
water is the biggest enemy, roofs, windows doors should never be overlooked.
cosmetics is the easiest thing to fix, and can be the cheapest and most expensive at the same time.
good luck. Its a fun experience, and you will learn alot.
