InspectHome

Find Homes With Confidence.

InspectHome is an open-source, transparency-first real estate platform that replaces traditional listing systems with a verification-based property network. Every listing is required to include full disclosures, supporting documents, and source attribution before it can be published.

Unlike conventional real estate platforms that prioritize advertising and lead generation, InspectHome is built around truth, documentation, encryption, and accountability.

Specification

1. Mandatory Property Disclosure System

Every listing must complete a legally structured disclosure form before publication.

Required disclosure fields include:

Structural condition
Roof age and condition
HVAC system status
Plumbing and electrical systems
Water damage history
Flooding history
Pest or termite history
Known defects or repairs
Insurance claims history
Renovation history
Environmental hazards

Enforcement:

Listings cannot be published without full disclosure completion
Disclosure requirements adapt by state and jurisdiction
Missing or incomplete disclosures block publication

2. Document Vault (Encrypted Upload System)

Sellers and landlords can upload verified property documents.

Supported documents:

Property deed
Title documents
Home inspection reports
Surveys
Renovation receipts
Permits and zoning approvals
Warranties (roof, HVAC, appliances)
Insurance documentation
HOA documents
Maintenance records

Security:

All documents are client-side encrypted before upload
The server never has access to raw document data
Zero-knowledge architecture ensures the host cannot decrypt data

3. AI Listing Assistant & Compliance Engine

An AI system guides users through listing creation and ensures compliance.

AI capabilities:

State-by-state real estate advertising law compliance
Fair housing law detection and enforcement
Listing description improvement suggestions
Detection of misleading or illegal phrasing
Required disclosure prompting
Document recommendation system

Example enforcement:

Flags discriminatory language
Requires correction before listing publication
Prevents unsupported property claims

4. Government Data Integration

InspectHome integrates publicly available government and municipal property data to enhance listing accuracy and provide independent verification layers alongside seller-submitted information.

Integrated Data Sources May Include:

County property tax records
Parcel and cadastral data
Zoning and land-use classifications
Building permits and inspection filings
Code violations and enforcement records
Flood zone and environmental hazard maps
Property boundary and GIS data
Assessor and valuation records (where publicly available)

Purpose of Integration:

Cross-check seller disclosures against official records
Improve listing accuracy and reduce misinformation
Provide buyers with independent, verifiable context
Surface potential risks or inconsistencies in property history
Enhance transparency without relying solely on user-submitted data

Data Handling Principles:

Government data is treated as a read-only verification layer
No modification of official records is permitted within the system
Data is displayed alongside listings for contextual analysis only
All integrated datasets are attributed to their original public sources where required

5. Listing Source Attribution System

Every listing must include its original source.

Required fields:

Brokerage name (if applicable)
Original listing URL
Listing agent (where required by law)
Listing origin type (owner, brokerage, builder)

Enforcement:

Listings without valid source attribution cannot be published
Source links are permanently displayed on listing pages

6. Neighborhood Intelligence System

Provides contextual data about the surrounding area.

Includes:

School district quality
Crime trends and statistics
Flood and environmental risk
Insurance cost estimates

7. Property Timeline System

Each property includes a permanent chronological record.

Timeline events:

Construction date
Ownership transfers
Renovations and upgrades
Building permits
Inspections
Repairs and maintenance
Insurance claims (when available)

Listing history

The timeline evolves over time, creating a living property record.

8. AI Fraud Detection System

InspectHome uses AI to detect fraudulent or suspicious listings.

Detection includes:

Duplicate listings across platforms
Stolen or reused images
AI-generated or manipulated images
Metadata inconsistencies
Fake landlord or brokerage identities
Suspicious pricing patterns
Address mismatches
Forged or altered documents

Enforcement:

High-risk listings are blocked from publishing

Ownership portfolio size (number of properties held)

This helps reveal institutional ownership patterns in housing markets.

10. Property Risk Dashboard

Each property includes a risk summary.

Risk categories:

Flood risk
Insurance risk

Permit compliance risk
