Public-record property intelligence

Property intelligence, deep and clear

Sentry Lake watches the property market, metro by metro, and assembles county records, tax history, sales, and neighborhood risk into a single report — so you invest with eyes wide open.

10 yrs: of tax & sales history on every covered parcel
3: analysis modules in every report — motivation, build, strategy

Three ways to put it to work

Deep analysis on a single parcel, a finder that suggests candidates across the market, or a watcher that alerts you the moment records change.

Individual property analysis

Looking at a specific deal? Get the full parcel picture — value, taxes, sales, structure, flood and ground risk, neighborhood context, plus seller-motivation, lot & building, and strategy feasibility. Pay per report or subscribe with a quota.

Property finder

Scanning for your next candidate? Set your criteria and the finder surfaces matched parcels in bulk — each with a lean profile and motivation signal. Promote any lead to a full analysis.

Property watcher

Already know the parcel? Watch it. Sentry Lake alerts you the moment county records change — tax liens, sales, permits, and value swings — so you act before the market catches on.

Open the watcher

Everything about a property, in one place

Where an appraiser digs through six county portals, Sentry Lake compiles the full picture and flags what matters.

County land & parcel records

Owner of record, legal description, zoning, homestead status, and assessed value straight from county GIS systems.

Tax & sales history

Actual taxes paid year over year, assessed-value trends, and the full public sales trail for the parcel.

Structure & permits

Dwelling type, year built, bedrooms, garage and basement detail — plus building permit history where public.

Flood & ground risk

FEMA flood-zone overlays, base flood elevations, soil behavior, and proximity to wetlands and special well areas.

Neighborhood context

Census income and affordability, crime activity within a half mile, and city-level rates benchmarked to state and U.S.

Seller motivation & feasibility

Public signals weighted into a seller-motivation read, lot and building potential from zoning, and strategy feasibility across buy & hold, flip, BRRR, house hack, and STR.

From address to insight in three steps

No phone calls to the county. No parsing PDF tax statements.

Access is gated behind your organization's identity directory. Your password never touches our servers.

Search any address

Enter a covered address and narrow it with property type, value, bedrooms, and year-built filters.

Read the report

One clean report — value, taxes, sales, structure, risk, and neighborhood — ready to export and act on.

Watch the yield, not the heatmap

Our reports separate signal from noise — flood zones, permit timelines, rent growth, and census affordability arranged the way an investor actually thinks, not the way a county served it.
