If you are really serious, you could buy a duplex with FHA 203(k) rehab loan, only needing roughly 3% of the purchase+rehab amount.

Did a duplex, bought with FHA 203(k) - which allows repair costs to be included in purchase mortgage.Wasn't easy, as had to get bids from licensed contractors, even though I planned to do most everything myself.Worked out well, refinanced out of the FHA into NOO loan and then bought another duplex with FHA and hacked that one.
