The Problem

Homeowners and landlords face chaos with scattered warranties, invoices, appliance manuals, and insurance documents, lacking a unified historical record system. Real estate professionals use tools like DataTree for public records (tax, deeds, liens) but not personal document management. There are approximately 81 million owner-occupied homes in the US, with landlords managing millions more portfolios, currently spending on fragmented property management software like AppFolio (above average pricing). This gap multiplies willingness-to-pay for landlords handling multiple properties.

Core Insight

Creates a CarFax-like centralized system for home ownership records including public data integration plus private uploads for warranties, manuals, invoices, and insurance, targeting consumers and small landlords overlooked by pro-focused tools like PropertyShark and Reonomy which lack personal document storage.

Target Customer
Solo landlords and indie real estate investors managing 5-50 unit portfolios (multiplies WTP), plus individual homeowners; US market includes ~15 million small landlords amid 50+ million rental units.
Revenue Model
Tiered SaaS pricing at $29-99/month per property/portfolio (inspired by PropertyShark $50-150/month and Crexi $249+/month), with free tier for single homes to drive adoption and upsell to landlord multi-property plans

Does not provide a CarFax-like historical ownership record system accessible to owners.

PropertyShark

$50–$150/month (tiered)

Adjacent

Provides sales, title, zoning, and comps data primarily for NY and CA with a focus on professionals, missing comprehensive storage and organization of personal home documents like warranties, manuals, and invoices for everyday homeowners or landlords. Lacks a unified ownership history tracker like CarFax.

Reonomy

Tiered/enterprise pricing; free trial

Adjacent

Offers AI-driven commercial real estate intelligence on building, tax, ownership, and market data but neglects residential homeowner needs for managing scattered personal records such as appliance manuals and warranties, with no emphasis on landlord portfolio document centralization.

DataTree

Contact for pricing

Direct

Delivers comprehensive property ownership, tax records, deeds, and liens for professionals but does not serve as a personal document management system for homeowners to store and access warranties, invoices, manuals, or insurance in one place, limiting usability for indie users.

Adjacent

Specializes in comprehensive US public records, property, mortgage, and foreclosure data via APIs but fails to offer a user-friendly platform for individual homeowners or landlords to aggregate and manage private documents like appliance manuals and warranties alongside public records.
