Multi-signal distress

Multi-signal distress means reading several independent public indicators on one property together, rather than treating any of them as the whole picture.

Why single-signal analysis fails#

Foreclosure alone misses most of it. Foreclosure requires a mortgage, and it appears only months before a sale. Property with no lender — inherited houses, vacant buildings, land held by absentee owners — never generates a foreclosure filing at all. It goes through tax forfeiture instead, over years, and a foreclosure-only view never sees it.

Tax delinquency alone is noisy. A single year of unpaid tax can mean a bill sent to a stale address, an owner who died, or a parcel somebody forgot. Most first-year delinquencies resolve.

Code violations alone say nothing about money. A correction order describes a building's condition. Plenty of well-financed owners get them.

Each signal is incomplete in a different direction, which is precisely why combining them works.

What combination produces#

Corroboration. A property with a tax delinquency and a code violation and a vacancy registration is not a data artefact.

Sequence. The order in which signals appear carries information. Maintenance stops before payments stop. A code violation followed a year later by a delinquency describes a different situation from a delinquency followed by a violation.

Timeline. Different signals imply different remaining time. A sheriff's sale sets a six-month clock. A tax judgment sets a three-year one. Knowing which is running is the difference between an urgent situation and a slow one.

Population. Signals in combination separate groups that look identical in isolation — an occupied home with a struggling owner, a rental whose landlord has stopped investing, and an empty inherited house nobody has authority over.

The hard part#

Not collecting the records. Reading them onto the same property.

Sources use different identifiers. Counties assign parcel numbers independently and the same number exists in several counties. Cities index by address, courts by party name, assessors by parcel. Owner names appear in different formats, with entity variations, across sources that never intended to be joined.

Getting a foreclosure filing, a code violation and a probate case onto the same parcel and the same owner is most of the work, and doing it badly produces confident nonsense.

What it is for#

Describing what is actually happening to a property, early enough for the description to be useful — to an owner who has time to act, to a counsellor deciding where to direct help, or to anyone trying to understand a neighbourhood's trajectory rather than count its foreclosures.
