THE INDEX

Why this MSI reads 64

Draft model

3 of 19 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-philadelphia-2026-09 weights nineteen public signals by how much each one changed the recorded four-month deed-transfer rate across all 465,000 Philadelphia single- and multi-family homes, checked on a holdout the model never saw (the top 0.5% of homes by score changed hands at 5.7× the citywide rate): trade permit +26, new-construction permit +18, vacant-structure violation +12, unsafe-structure violation +12, construction complaint +11, sheriff-sale flag (june 2022 list) +9, upkeep violation +3, maintenance complaint +3, delinquent property tax (june 2022 list) +3, structure violation +2, owner mails out of state +2, dangerous-building complaint +1, make-safe permit -2, bought since 2024 -3, owner mails elsewhere -13, no recorded sale -15, alteration permit -17, owned for 20 years or more -28, homestead exemption (owner-occupied) -35. 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.
