Show HN: OpenAVMKit – open-source toolkit for real estate mass appraisal (AVMs)

https://www.openavmkit.com
4•larsiusprime•5mo ago
I'm the maintainer of OpenAVMKit. It's a free and open source toolkit for real estate mass appraisal. I want to make it easier for analysts, researchers, and assessors to build automated valuation models (AVMs) from public data sources. It's in early development, but has reached a stage where it's useable and I'm gathering public feedback.

Stuff it can do:

- Data enrichment: add additional data from public sources like OpenStreetMap, Overtrue, US Census, USGS, or your own shapefiles

- Modeling: run many different algorithms, such as MRA, GWR, LightGBM, XGBoost, CatBoost, as well as ensembles, all through one interface

- Reporting: generate IAAO (International Association of Assessing Officers) compatible ratio studies and other statistics and graphs

- Reproducible workflows: build data pipelines out of input data and settings file, so the same person can reproduce your work on another computer starting with the same ingredients

There's a "getting started" section in the docs with a minimal example that should let you download the test jurisdiction and run through the basic example notebooks.

I'm looking for feedback on what features people are the most interested in and what kinds of tutorials/documentation would be the most helpful for me to focus on.

The official site is here: https://www.openavmkit.com

The github is here: https://www.github.com/larsiusprime/openavmkit

We also have a bit of a writeup on it here: https://progressandpoverty.substack.com/p/openavmkit-a-free-...

Happy to answer any questions in the thread.
