Milwaukee. restricted:
City publishes a delinquent-tax-certificates XLSX (~12K parcels), but in-rem foreclosure is a rolling petition process — no scheduled annual auction. We surface these as OTC inventory with NULL auction_date so they don't expire daily, but they are NOT scheduled-sale parcels in the way Baltimore's tax sale is. Investors must contact the City Treasurer directly to acquire.

How we rate these
Every listing says one of four things: Worth a look, Needs review,
Screened out, or Not enough data yet. Next to it is a count of how
many of the checks we have finished, and what that much evidence is good enough for.
One number cannot say both how good a parcel looks and how much we actually know
about it, and a low number reads as a verdict. So we do not print one.
“Not enough data yet” is not a judgement about the property.
