Lots of variables, but if I had to reduce it to one metric, I would use:  Minimum profit of 15% of ARV.So, on a house that we believe will resell for $400,000, we'd be looking for a minimum profit of $60,000.That said, here are a few additional thoughts:-  Obviously, not all rehabs require the same amount of time and risk, so if we run into something that is out of the ordinary for either (much quicker/longer or much lower/higher risk), we will adjust that requirement.-  These days, good deals are hard to find.
