THE INDEX

Why this MSI reads 65

Draft model

2 of 12 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-chicago-2026-09 weights twelve public signals by how much each one changed the recorded six-month sale rate across all 566,000 Chicago homes, checked on a holdout the model never saw (the top 1% of homes by score sold at 4.8× the citywide rate): vacancy complaint +22, new-construction or demolition permit +17, renovation permit +16, unpermitted-work complaint +16, upkeep complaint +15, bought within the last two years +11, building-violation complaint +9, delinquent property tax +8, owner mails out of state +4, permit valued at $25,000 or more +4, owner mails to the property -5, owned for 20 years or more -10. 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.
