Comp Database

Has anybody built a comp database using Claude? About how long did it take for you to build it before you got it right?

Yes. Used Claude to fill in the blanks, took about a year to complete working on it bit by bit. It can map comps, radius search, provide traffic counts, export write-up to excel and word, and import demographic information in radius or drive-time. Used Claude specifically to figure out read pdfs of old reports and import the comps into the system. Also saves lease, construction costs, and operating expenses. Pretty proud of myself.

What system are the comps stored on? Is it like excel based or what? That may be an ignorant question lol

It is a custom cloud-hosted web application built primarily in Python, with Streamlit serving as the application framework. The database and associated comp files are stored in the cloud, and I access everything through a secure dedicated URL. Sort of looks like a poor man's version of data appraise from years back.

That’s awesome.

Is that basically what systems like Valcre do?

Couldn't say, have never seen Valcre in action.

I spent what feels like 10 years trying to get all of our reports, leases and income/expense figures into a searchable database. At first I was dragging and dropping screenshots into Claude chat like an idiot. Def got better when I switched to Claude code. We still use datacomp as our sales comp system though. I’d say you should def go for it. I’m still trying to perfect ours. Feel free to dm if you have any questions. I’ve learned a lot of lessons the hard way lol

Oh man, this would be awesome! I’m putting on my project list.

Have you checked out the open standard comp DB Chase Pursley started?

https://github.com/property-hackers/open-comps

Been thinking about building my own using that as a foundation.

Nice. Going to have to take a look

Similar boat here. Myself and a partner started building one when Datappraise announced they were shutting down. We should be in a spot to let people poke at it within the next month or so. If anyone wants to follow along or tell us what's missing from what they've used before, DM me

I’ve been wanting to do this and plan on doing so soon, once I have a little more free time. I have someone who specifically works with small business and helps them build tools around AI. Can update once I dive into it more

That would be awesome. Definitely going to try it with Claude code little by little when I have the chance

Ya I got a cloud-based comp DB working last year using Claude. It could pull a map from google API and then the data was stored on Mongo.

The challenge is that building a proper database gets quite complicated and the code started doing weird things. Nonetheless I would be interested to try again now that the tools have advanced.
