THE INDEX

Why this MSI reads 59

Draft model

1 of 6 checked public signals observed, covering 100% of the model. The score is public; the signal-by-signal reasons, source documents, and owner details are in LienSuite.

Method and limits. MSI v0.2-cook-suburbs-2026-09 weights the six public signals available county-wide by how much each one changed the recorded six-month sale rate across all 677,000 suburban Cook County homes, checked on a holdout the model never saw (the top 1% of homes by score sold at 3.0× the suburban rate); the six City of Chicago signals cannot be checked outside the city and are left out of both the score and its coverage: bought within the last two years +9, delinquent property tax +9, owner mails out of state +13, permit valued at $25,000 or more +12, owner mails to the property +2, owned for 20 years or more -3. The "in 100 homes" figure is the model's fitted probability for this combination of signals. It describes homes like this one in aggregate; it is not a claim about this owner's intentions, and it is not LienSuite's paid deal score.
