Predicting property type from mixed sources

The situation

In loan origination, property type matters. The business relied on the type each applicant stated. There was no quality check, and there were many gaps.

What we did

We built a model that infers property type from other characteristics of the property, together with images, planning data and graph typology. Each source fills gaps the others leave.

What changed

Every property now has an independent measure of its type. The number of properties that can be classified independently rose by 4%.

Why it matters

The lender no longer has to take the stated type on trust. Where the two disagree, it knows to look closer.
