I do fix & flips and build 3-4 unit rentals in the SoCal area. It's super competitive here and we have a large flow of off-mkt homes coming our way, so we had to develop tools to speed up acquisitions/underwriting.
I built something that allows VA's or very green staff members the ability to properly distinguish opportunity as if they had years of expert experience & local market knowledge.
It will run sales comps & estimate ARV for you:
And has drilled-down market stats that are actually useful! The top chart below quickly shows you what the renovated, avg and distressed homes sell for in that area on a $/sf basis over time, so if you are estimating way over the top line, you instantly know something is off, maybe you have an outlier comp on your hands, etc.
It doesn't have STR data, because any STR we build must also pencil as a LTR to avoid being upside down if it doesn't workout, so we use normal residential lease data when underwriting our rentals.
As for forecasts on the market, I don't do any aside from the current Q trending % at the footer of the charts, and it's really just the current Q's average data/performance held constant and applied to the rest of the quarter (since not fully done with Q yet). This yields the % up or down we are in the current Q relative to the last fully closed Q, so as the transactions roll in each day I get an idea of the current Q's direction.
I'll always advocate for building your own tools so you can build them to suit whatever your development schemes require for the best experience, efficiency, and confidence. This one only has SoCal data, but if you end up looking at deals out here, use it! Hope this gives you a good idea of how these tools help us. Would be glad to hear suggestions/feedback on it as well if you use it!
