I made LA/Ventura & SF/Bay Area Underwriting tools you can use
Hey, thanks for the time, this is my first post! I'm a UCSD Real Estate Development 2020 grad with a background in coding that got into flipping SFRs in the LA/Ventura area. When we get them at a low enough price, we build them into 3-4 unit rentals via ADUs with a 10-12% cap upon stabilization, otherwise we buy flips that we estimate will make ~20%+ return annually. Checkout 3790 Somerset Dr or 7115 Royer Ave, two of our flips that sold last month.
To do this better (more accurately, efficiently, and with more confidence), I created RUNCOMPS. I've been using it for ~2 years now, honing everything from functionality to recently building out the front-end design and using it on every property that comes my way for evaluation.
To quash any self-promotion claims, I am only looking for FUNCTIONAL feedback & suggestions from investors/developers/underwriters like yourselves on how I can improve this app to work better for you/me/everyone. There are NO purchase options on the following page, I am giving you all full access for free so I can collect feedback from the community here:
app.runcomps.org
For LA/Ventura data: your_best_friend
For SF/Bay Area data: robby the man in sf
I just finished the SF/Bay area today, here are the first 3 homes I used as a test of the Sales Comps ARV estimate function, literally the first 3 I picked at random from RedFin sold < 1 week that looked renovated. Pretend we found a fixer in this area of similar BR/BTH/SF as this property for $2.5M and we wanted to quickly know what it would be worth renovated:

Then to see if your renovated product in 6 months will be higher or lower in value, use Market Stats. Specifically, I like the Specific Zipcode function with the absorption and price plotted. Dipping absorption = lower price eventually, we want to see steady/climbing absorption and steady/climbing price, it indicates a good market:

- - Its critical to realize the data to the right of the red-dash is filling up as transactions occur in the current Q. So right now, I know the 16 sales in 94402 that have occurred since 7/1/23 have been lower in $/sf than the last Q average, hover over the line for exact metrics.
- - Or use the 'LA & Ventura' or 'SF & Bay Area' options under Sales or Rents to get an idea of ALL markets and their performance over time.
Hopefully this will stay up and I can get some feedback from you all! Looking forward to chatting below,

Thanks. That all makes sense, but how do you come up with a projection for renovated vs non-renovated properties? Doesn't that require classifying each property as one or the other to generate your stats.
For example, if there are 50 properties within the search radius and 20 have been renovated and 30 have not been renovated, then a projection for the after repair value cost of a house would be based on the sample of 20, and a projection for the current value cost would it be based on the projection of 30. But this requires you to put properties into one bucket or the other. How do you know which bucket to put a property in?
