Home intelligence for homebuyers
A clearer picture of what any home is worth.
Great homes are made by better owners. Tarn makes that visible — permit history, code-era risk, and true cost of ownership, synthesized from public records in minutes.
Free while we're building. In exchange, we ask what wasn't useful.
Year built is optional, but it's what unlocks the code-era risk exam — lead paint, electrical panel and wiring era, and pipe material flags all depend on it. Without it you'll still get the detailed permit history, just not those findings.
The fourth opinion
You already get three opinions. None of them cover this.
Your walkthrough. Your agent, who's paid a percentage of the price and only paid if the deal closes. Your inspector, whose assessment is visual and limited to a few hours. None of the three gives you the property's actual history and risk profile — the record of what's really been done to a house, and what hasn't.
Tarn is the fourth opinion. It doesn't replace the other three — it's the layer none of them provide.
What Tarn answers
Four questions, before you're locked into an answer.
How good a deal is this house?
Not just the market price — what it's actually worth given its real condition, history, and risk.
What will I need to do to it?
A forward-looking work list based on the home's age, code era, materials, and region.
When will I likely need to do it?
Timelines, not just flags. Plan to replace within 3–5 years, not just "this is old."
What will it likely cost?
Budget ranges by item, so you can plan for ownership, not just the purchase.
Early access
We're still building this. Tell us where it falls short.

The deal is simple: you get a free report, and you tell us what's missing, wrong, or confusing — that matters more to us than what you liked.
