parcel-edge

Scored, dated, deadline-stamped COMMERCIAL property-tax over-assessment leads. Each lead is a parcel whose assessor implied-market value EXCEEDS its most recent CLEAN arm's-length sale price — a candidate over-payment a contingency tax-appeal firm pursues. Counties that publish a public sale price: cook-il, allegheny-pa, philadelphia-pa, king-wa, maricopa-az. (Texas/Georgia counties are non-disclosure — over-assessment is an honest null there; use exemption_flags instead.) Candidates from PUBLIC data; the firm confirms valuation. Not legal/valuation advice.

Fresh ASSESSABLE construction permits (funded builds) entering the permit→financing window — prospects for hard-money / construction lenders racing the permit-to-loan gap. HONEST: loan-absence is UNVERIFIED (no current free per-parcel mortgage feed); this is a time-boxed absence-window WATCHLIST, re-checked as financing appears. Cook County. Permit amount, age, window status, applicant, work description.

STALLED-PROJECT candidates for SURETY / DRAW-CONTROL firms + the exposed construction lender. Each is a large ASSESSABLE building permit (real funded build) whose status is still NOT CLOSED well PAST its size-appropriate build window — an issued-but-never-finaled permit (no certificate-of-occupancy proxy reached). Built off the SAME nightly Cook Assessor Permits pull; the permit carries its own status field. Permit amount, age, expected build window, overdue days/%, current status. HONEST: 'stalled' is a STATUS+RECENCY inference, NOT a verified work-stoppage (paperwork lag / phased builds / slow finaling can also leave a permit OPEN) — the surety/draw-control firm confirms on the ground. Counties that do NOT expose permit status return an honest null for this stream; Cook does, so it ships here. Cook County.

Non-conclusory exemption-contradiction FLAGS: parcels where a residential/homestead exemption coexists with a NON-OWNER-OCCUPANT owner of record (Allegheny: HOMESTEADFLAG=HOM + corporate owner; Cook: residential parcel deeded to an LLC/corp/trust grantee; Philadelphia: single-family homestead exclusion + entity owner; Travis TX: active 10% homestead appraisal cap on a homesite parcel + LLC owner; Fulton GA: homestead ExCode + entity owner; Harris TX: LLC/corporate owner on a residential parcel — owner-type watchlist, HCAD publishes no homestead boolean to confirm). Candidate improper exemptions for exemption-audit / recovery contractors (~30% contingency of recovered liens). Full owner/exemption EVIDENCE CHAIN. NEVER a fraud verdict — the contractor confirms occupancy. Counties: cook-il, allegheny-pa, philadelphia-pa, travis-tx, harris-tx, fulton-ga.

INVESTOR DESK (paid, $0.50 USDC/call; free preview): per-parcel tax-deed title-research report for a single Allegheny County PA PIN. Returns every UNSATISFIED County/School/Municipal tax lien on the parcel bundled into one surviving-lien stack with a per-taxing-body split + total, the tax-year span (a long tail signals a likely JUDICIAL 'free & clear' sale; a short one an UPSET sale where the buyer takes SUBJECT to surviving liens), and the PA statutory redemption posture (72 P.S. §5860 — PA has no general post-sale redemption; the risk is surviving liens). The cross-join a tax-deed investor pays $150–500/parcel for. CANDIDATE title input, NOT a title opinion — confirm sale type + named lienholders with the county/counsel before bidding.
