01The problem

Everyone sells property records. Nobody sells the answer.

The records are free and already downloadable. Access was never the problem. The same building is a borough-block-lot in the tax roll, a parcel number upstate and an ACRIS document in the deed index. The same person is a dozen spellings across a dozen entities.

Nothing resolves them to one real thing, and nothing cites a source.

A lender asks

How much am I really lent to this one person, across every entity they use?

unanswerable
An investor asks

Who actually controls this building, and how do I reach them?

unanswerable
A diligence team asks

What is behind this borrower’s track record, and can I show my work?

unanswerable
02Plays

48 ways a building makes or loses money, checked at once.

An analyst holds a dozen of these in their head and checks them one at a time against a county website. Mimir holds 48 — development, tax incentive, operational, debt and risk — scans them all, and says which the record supports, which it contradicts, and which it cannot evidence.

  • 31 upside plays and 17 downside plays, both directions of the same scan
  • Three honest states, never a ranked list of recommendations
  • Hard blockers are dispositive — rent stabilisation kills a teardown regardless of the envelope

03Opportunities

Screen 22 million properties on what the record says.

Adjacent lots in the same hands. Owned free and clear. Held fourteen years. Debt maturing into a wall. Every filter is a recorded condition with its filing attached — so the screen is a fact, and the conclusion stays yours.

  • Results resolved to the person, so entities do not fragment your list
  • No seller-motivation score, deliberately — that hides which facts drove it
  • Save a screen and it becomes a standing alert

04Ownership

The name on the deed is a company. We find the person.

US companies do not file their beneficial owners in a public registry, so a registry lookup cannot reach the answer. Mimir infers control from behaviour — deeds, mailing addresses, registered agents, co-borrowers, timing — and shows the evidence and confidence on every hop.

  • 961K properties across NY and FL resolved through a company to a person
  • Chains up to six entities deep, each hop scored and sourced
  • Confidence shown per edge, never hidden inside one number

Twelve entities become one track record.

A sponsor who used a different company on every deal looks like twelve strangers in the county index. Resolve the person and they become one borrower with one history — every property, every mortgage, every lien that followed them.

  • Every entity a person has used, collapsed into one view
  • Real concentration across the whole portfolio
  • Adjacent parcels in separate entities surfaced as one assemblage

Read the debt before you commit.

Mortgages, assignments, satisfactions, liens, lis pendens and tax distress, assembled per building from the recorded instruments rather than from a borrower's summary of them.

  • Senior, mezzanine and junior positions with recorded amounts
  • Liens and lis pendens the borrower did not mention
  • Every line links to the instrument that created it

07Evidence

Cite every field, not just the report.

Provenance is carried per field, not stapled to the bottom of a PDF. Any value on screen opens to the government record it came from — the source, the record id, and the date it was recorded.

  • 100% of 21.4M owner records carry a source and a field-level map
  • Strong enough for a credit file or a securitization reviewer
  • Re-derivable: the same inputs always produce the same answer

08Alerts

The record changes. You hear about it.

Deeds, mortgages, liens, foreclosures and entity filings land continuously. Save a search once and the terminal tells you when something inside it moves — with the document attached, so the alert is a fact rather than a hunch.

  • Lis pendens, new mortgages and deed transfers as they record
  • Tax delinquency and code violations rolled up to the resolved owner
  • Every alert carries the instrument behind it

09Spatial

Quiet assemblage, made obvious.

Buying up a block through separate entities is invisible parcel by parcel. Resolve the controller and the pattern draws itself — the adjacent lots, the order they were acquired, and the entity each one sits behind.

12Why it matters

Five borrowers, or one?

Underwritten one entity at a time, a single sponsor reads as five unrelated names on five unrelated files. Resolved, the real exposure appears — and with it the question of whether you meant to take it.

Underwritten one entity at a time, this reads as five unrelated borrowers. Resolved, it is one.

The fastest way to judge the system is to watch it re-derive something that took you a day, with a citation on every step.
