Why we exist
Buying a home forces several different questions into one decision: which records match the exact property, which closed sales deserve review, what ownership may cost, and which legal, physical, insurance, title, and financing facts are still unresolved.
Twellie organizes those questions into an auditable report. It does not assume that software can replace professional judgment, and it does not combine a strong signal in one area with a critical gap in another to produce a reassuring overall score.
Twellie was built for buyers who want to inspect the evidence themselves. It supports research and coordination; it does not replace an agent, appraiser, inspector, attorney, title professional, lender, or insurer.
What the report actually contains
- Closed-sale evidence — qualified sales with dates, prices, property facts, distance, qualification notes, and provider references.
- Evidence ledger — every decision component is marked supported, partial, missing, ambiguous, demo, or in need of professional verification.
- Condition observations — available listing-photo observations become inspection questions. They are not a professional inspection or an automatic price adjustment.
- Ownership-cost planning — mortgage, tax, insurance, HOA, maintenance, utilities, and closing inputs are shown as assumptions to verify, not quotes.
- Coverage status — source-backed, partial, missing, conflicting, or requiring professional verification.
- Due-diligence tasks — a record of the inspection, title, insurance, appraisal, financing, and closing questions still owned by the buyer and relevant professionals.
Who writes the content
Twellie's product team writes the current public methodology and buyer education. Some material is AI-assisted. A page should be treated as professionally reviewed only when it names the human reviewer, credentials, jurisdiction where relevant, and review date. See our editorial policy for the current process and limitations.
What we don't do
We don't write USPAP-compliant appraisals, and the current public product does not publish a Twellie value estimate, fair-price label, evidence range, or offer ceiling.
We don't replace a home inspection. Listing photos cannot establish structural, roof, HVAC, plumbing, electrical, moisture, pest, or concealed condition. Use an appropriately licensed inspector and specialists before removing protections.
We don't give legal advice. Real-estate contracts and attorney requirements vary by state and transaction. Obtain qualified local legal help when appropriate.
We don't sell your data. We're not an agent referral network, we don't earn commission on transactions, and we don't share your address searches with mortgage brokers, lenders, or anyone else. See our privacy policy for the full disclosure.
How we make money
The consumer offer is a $50 per-property evidence dossier with no recurring subscription. Checkout requires confirmed commercial data rights, live core sources, exact-property preflight, authentication, secure persistence, and Stripe. Twellie does not make a dossier more favorable based on whether the buyer proceeds.
Methodology and accuracy
The current property matching, closed-sale qualification, source-status, history, cost-assumption, and limitation rules are documented at our methodology page. Internal valuation research remains outside the public product until a prospective benchmark supports a separate release.
Our standards
- No unsupported accuracy claim. We do not publish a headline accuracy percentage until an out-of-time closed-sale benchmark can support it by segment.
- Claims must match the current product. Retired features and unverified coverage, savings, or accuracy claims do not belong in public marketing or structured data.
- No affiliate links. We don't recommend products to earn commission. When we cite a tool, it's because we think it's the right tool for the job.
- Primary-source preference. Material methodology and consumer-protection claims should link to primary regulators, standards bodies, or official guides; unsupported claims should be removed when found.
Where to start
Start with the sample property report. Then read the evidence methodology and use the home buyer due diligence checklist to see which checks remain outside any online report.
