I think Alvin is doing a bunch of those or was doing them but not sure. Me I like plain old vanilla. I buy low,rehab and fix up,and sell high.
Every 1 to 2 months making about 25 to 50k depending on the deal.When the right deal comes along you have to pounce on it.
Work hard and save your money or find a cash partner to split deals with.
Just my opinion good luck.
