Buy a house if possible. The housing market can't get much worse and its a buyer's market.
At the end of 4 years I made a profit on my house.
Nice idea, but what happens if the market crashes while you are in school? The market can get a lot worse. Don't tell me this has never happened before. The market crashed in Texas in the 1980's and it took more than 10 years to recover. Many people lost their homes and many people simply walked away from their mortgages.
For someone who clearly has no money--we are talking about a student here--it is quite a risk. Sure you can hang on to your house until the market comes around but there's no guaranty it will for many years and you might be stuck in this town. If you have the desire to rent out the house, then be prepared to do a lot of work. If you are trying to rent the house while living in another state--good luck! It's a royal pain in the rear!
I speak from experience. I've bought and sold a lot of houses in the last 20 years.
Go ahead and buy a house, but realize that there is risk involved. And if you have to get someone else to sign with you, again because you are a poor student and may have not established any worthy credit, then you are risking someone else's money.
Not everyone makes money selling houses, but then a lot of people do. Just can't predict the future with 100% certainty.
Hey, just FYI... Just looking to provide perspective...
