how to purchase real estate ad sell it for profit?

Answer 1

Look for a bargain, then buy low and sell high

Answer 2

if you find a house that you think is a good sale, or a good deal, buy it. then fix it up (invest in it a little) and sell if for more than you bought it for. The only thing is... you have to have the money up front. I wouldn't recomment getting a loan if you're buying it just to make a profit.
