I have come slightly close to getting out all of my initial investment in the short term but I have not gotten out all of my investment (purchase + rehab) out due to 1) typically we do not get 80% LTV (we typically get 70% LTV) 2) the refi appraisals come in below market value (common issue in san Diego).Therefore I have yet to achieve the infinite return in the short term. 

That way you can still utilize it without taking the penalty hit.

Also, I'm at a disadvantage not knowing the area, the costs associated with utilities and maintenance, upgrades, etc, and the good and bad areas of town.

Even if I don't utilize the BRRRR method or force appreciation it still looks like a better investment.
