Brandon is estimating similar capex on his five-plex to what Ben estimates for a SFR.It would be great to get a "four-years-later" update from Brandon on this property's status, but I'm also curious whether others here think that Brandon's feat can be replicated - and actually pan out the way his article forecasts, or is Ben's cold water the final word?
