A story behind the task


Reali is a US-based startup that disrupts the traditional real estate model by introducing a flat fee commission for buying or selling a house. Reali uses technology, which streamlines the buying and selling process and allows customers to get professional support from their real estate expert team. Price predictor is one of the core features of the Reali platform that supports the bidding process with more AI-powered decision making.

But there was a challenge…

How to ensure accuracy of prediction results based on data about houses as well as historical data about transactions?

Reali entrusted the Temy engineering team with validating the entire concept

How we started

First steps

Our initial cooperation began with a research project that we allocated one month to achieve a 95% prediction precision over the sample dataset. The initial dataset was split into training and test subsets to test the accuracy of the predictions.

In data we trust

Our approach

We used linear regression to understand how listing prices, area, year of construction, condition, and the number of rooms impacted the selling price of the house. Another useful insight that we uncovered was that some data entries from the initial dataset contained errors that resulted in low performance within the model. To solve this issue, we created a script that filtered incorrect input data.

What we are proud of

Temy’s role

As an outcome of this project, we have trained a set of models that were very close to the initial target that made it viable from the business perspective to invest further in this direction. In addition to that, we learned valuable business insights as well as challenges that should be addressed in the production version of the price predictor.
