Buy low, sell high. You need “data science” to do this? $VNQ is up 33% since 2016. Do you realize how dumb and bad you have to be to lose money on real estate in this time? I imagine randomly picking homes off the MLS would have yielded better returns in the last five years than whatever Tableau-powered nonsense the biz ops analysts at Zillow used. The entire iBuying concept is a farce, completely divorced from basic fundamental analysis.
