In the Netherlands, we have rules that determine the maximum rent allowed for a dwelling based on its properties and quality. These rules are quite complex and can be found on the Huurcommissie's website.

We’ve built an open-source Python package to calculate the amount of points a house is worth based on these rules: woningwaardering.

woningwaardering means “home valuation” and it is a point system in which a dwelling is awared points based on its properties and qualities. The maximum rent for a dwelling is directly related to the amount of points it is awared.

Ed Donner fine-tuned a Llama-3.1–8B model to predict Amazon product prices based on their descriptions. This inspired me to try to predict the points of a dwelling based on its description, instead of using our own woningwaardering package.

At the social housing organisation I work, Woonstad Rotterdam, we have lots of data about our 60,000 dwellings. We’ve implemented data quality checks to determine which dwellings have near-perfect quality data using our open-sourced pyspark-testframework package. Of our ~50,000 self-contained dwellings, ~25,000 have a near-perfect data quality.

Even though the data quality of these 25,000 houses is very good, there are still limitations to the dataset. For example, we don’t… Read the full blog for free on Medium.
