Use current property tax and assessment context as underwriting inputs, then stress-test rather than assuming today's bill remains constant.
What this guide is for
Use public property intelligence to improve underwriting questions.
Investors need to know which numbers are current facts, which are assumptions and which property exceptions deserve more money or time before closing. Watchdog can organize annual taxes, assessment context, transaction chronology, property characteristics, permits, environmental screens and change history around one asset.
The platform should make diligence more disciplined, not create false certainty. A source-backed exception is a reason to verify, stress-test or hand the issue to the right specialist.
Boundary: Watchdog does not provide investment advice, predict returns, guarantee future taxes, establish property condition or replace title, legal, engineering, environmental, insurance or contractor diligence.
01 · Workflow
High-value investor workflows.
Use the property record to test the acquisition story and decide what needs deeper diligence.
Use permits, property characteristics, changes, sale history and environmental screening to prioritize direct verification.
Use common town and county definitions so candidate properties are not compared with mixed tax years, incompatible rates or stale context.
Save candidate and held properties so material assessment, permit or record changes can re-enter the diligence or asset-management workflow.
02 · Interpretation
Read the property fields as underwriting inputs.
Keep sourced facts, Watchdog-derived signals and your own financial assumptions clearly separated.
Annual property taxA recurring expense input that should be reconciled and stress-tested rather than copied blindly into a long-term pro forma.
Assessment / equalizationHelps explain the tax environment and assessment sensitivity. It is not a prediction of a future bill or sale value.
Recorded saleTransaction chronology and price context, subject to independent diligence on conditions, consideration and relevance.
Property class / characteristicsUseful for segmenting a pipeline and spotting inconsistencies in an acquisition memo.
Permit / change signalsCan reveal follow-up questions about work, closure, timing or public-record accuracy.
Environmental / flood contextAn early risk screen that should be handed to authoritative environmental, engineering or insurance review when material.
03 · Hypothetical examples
How Watchdog assists investment diligence.
These examples use fictional properties and no real residential address.
An investor models a hypothetical acquisition with today's tax bill, then runs a higher-tax scenario instead of assuming the present amount is permanent.
A property is marketed as recently improved while the public permit/change picture is incomplete. The investor requests direct documentation before crediting the improvement in underwriting.
Several candidates meet the same price target. Watchdog helps rank which ones need immediate diligence based on tax, change and risk exceptions.
A municipal assessment shift appears during the hold. The investor revisits carrying-cost and buyer-affordability assumptions instead of discovering the issue at disposition.
04 · Before you act
Investor diligence checklist.
Ask these questions before a property-data observation is promoted into the underwriting model.
Which numbers are sourced facts and which are underwriting assumptions?
How sensitive is the deal to a change in annual taxes or assessment context?
What public-record exception could create time, capital or closing risk?
What needs a contractor, attorney, title, environmental or insurance specialist?
Am I comparing properties using the same source vintage and definitions?
