THE INDEX

Why this MSI reads 64

Draft model

2 of 15 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-milwaukee-2026-09 weights fifteen public signals by how much each one changed the recorded seven-month arm’s-length conveyance rate across all 123,000 residential parcels in the City of Milwaukee, reading every owner-side signal from the Assessor’s December-2025 roll so no signal reads the buyer’s state, checked on a holdout the model never saw (the top 0.5% of homes by score sold at 3.5x the citywide rate, the top 10% at 2.6x — a flatter top than Motsele’s other cities, because Milwaukee publishes few dated activity records).: vacant per the assessment roll +25, new-construction permit +21, alteration permit +17, litter or debris 311 request +16, owner does not live at the property +12, owned by a company or trust +12, building-disrepair 311 request +10, garbage or rodent 311 request +5, owner mails out of state +2, owner mails outside milwaukee +2, bought since 2024 -2, two or more dwelling units -3, built before 1920 -3, assessed under $50,000 -6, no arm’s-length sale since 2014 -8. 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.
