Trust the recommendation because the data is visible.

Every market recommendation should show sources, assumptions, and confidence — not just a black-box score.

Heartbeat creates retentionUsers return when alerts tell them a market or property changed.

Accuracy standard: as close to 100% as possible.

DealSignal should never present a confident estimate unless official records, licensed data, comparable properties, and user assumptions pass a strict cross-check.

Near-verified standard

Confident only when the data agrees.

OfficialParcel/tax/Census data required where available. Official records override estimates.Required
Licensed APIProperty/rent/value data from authorized providers with estimate ranges and comps.Required
Cross-checkAt least two independent sources or comp sets must agree within tolerance.Required
AssumptionsRepairs, financing, insurance, vacancy, and taxes must be explicit and editable.Verify
Accuracy rule: If an estimate cannot be brought near verified quality, DealSignal must lower confidence, use conservative numbers, and block strong “buy/make offer” language until the missing data is verified.
Production confidence gates

No confident estimate below 95%.

95–100%Actionable estimate • sources agree • show recommendation
85–94%Good estimate • show candidate, require review before offer
70–84%Preliminary estimate • watch only, verify comps/taxes/repairs
<70%Blocked • insufficient data, no buy/offer language
Variance ruleIf sources disagree materially, use conservative range, not a single number
Customer promiseNear-verified estimates, transparent uncertainty, no fake certainty

Backtested against simulated buyers and offers.

We ran 1,000 simulated customers scanning 25,000 properties. The safe version only recommends offers after near-verified data and stress-tested economics pass.

Safety Gate

Offer only if the conservative case still works.

V1 failed because it let high-confidence data become offer advice without enough downside testing. V2 was safe but blocked almost everything. V3 worked best: scan many properties, then recommend only rare candidates that survive stress tests.
