Buying our current house as a foreclosure. It was the first house we purchased and we got a great deal (especially because we went FHA and the house didn't appraise for list so the bank lowered the price further). We are selling that house now and close next week with a sale price that is $40k over what we paid.

going to college and putting money in 401k. I've dabbled in lots of other things nothings really paid off. Although, I didn't buy a house for 95K and flipped it for 125K 6 month later.
