I invest using BRRRR and what I've seen lately as the biggest obstacle to that strategy, has been the initial hard money lenders, with the recent market changes this past year are doing lower ARV percentages ...example going from 80% ARV down to 65-70% ARV to mediate their risk, requiring more out of pocket initial money's.
