You have a prospect on the phone. They want a homeowners quote. You ask when the house was built and they say "I think the eighties?" You ask the square footage and they guess. You ask what the roof is made of and they go quiet.
Every agent who quotes personal lines knows this call. The carrier wants a dozen facts about the structure before it will rate, and the person who lives in it knows maybe four of them. So you open a second tab, then a third, and start hunting.
This post covers what an underwriter actually needs to know about a house, where agents usually go to find it, and a faster way to get all of it from one street address.
Whether you are keying into a carrier portal, a comparative rater, or an ACORD 80, the property questions are roughly the same:
Get any of these wrong and the best case is a re-rate at binding. The worse cases are a policy issued on bad information, a claim dispute, or a cancellation notice when the inspection report comes back.
There is no shortage of places to find property data. The problem is that each one has a piece of it.
| Source | What it is good for | Where it falls down |
|---|---|---|
| County assessor site | Year built, square footage, parcel number, owner of record | Every county has a different site, some are not online, and searches are by owner or parcel rather than address |
| Consumer listing sites | Beds, baths, photos, recent sale | Data is self-reported by listing agents and often stale once a house is off market |
| MLS | Detailed listing sheets | Requires a real estate license or a friendly agent, and only covers homes that were listed |
| Asking the client | Occupancy, updates, and anything not in a public record | Clients guess, and the guesses skew optimistic |
| Carrier prefill | Some carriers pull year built and square footage for you | Only inside that carrier's portal, and you still have to check it |
The usual workflow is to bounce between two or three of these, copy the numbers into the quote, and hope they agree. When the assessor says 2,140 square feet and the listing says 2,400, you pick one and move on. That is the moment a future claim problem is born.
The Property Data Lookup skill in the Agency Skills Library was built to replace that tab-hopping. You give it a street address and it returns a property profile with every field an underwriter cares about, pulled from multiple independent property record sources and cross-checked against each other.
You ask for it the way you would ask a producer sitting next to you:
Look up 2210 Hollow Oak Ct, Murfreesboro TN. I need year built, square footage, roof, construction and lot size before I quote the home.
And you get back something like this (example output, values illustrative):

That is the whole underwriting picture for the house in one place, with nothing to sign up for. The data cost is included in the library subscription, so there is no county account, no data vendor contract, and no API key to paste anywhere.
It works for any US address. There is no per-state setup and nothing changes when you quote a home two states over.
The most useful thing on that profile is not any single number. It is the marker next to it.
When two or more independent records agree on a field, the skill labels it confirmed. Those are the numbers you can quote to an underwriter with confidence. When the records disagree, the field is labeled unconfirmed and shows you the competing values instead of silently picking one:
Living area (sq ft): 2,318 [UNCONFIRMED: records disagree — also seen: 2,640]
That is your cue to ask the client one specific question ("did you finish the bonus room over the garage?") rather than a vague one. It turns a guess into a verified answer, and it leaves a paper trail showing you checked.
An agent who quotes on a confirmed square footage and asks about the unconfirmed one is doing exactly what the underwriter wants. An agent who copies the first number they found is not.
The owner section is where a lot of misquoted policies get caught early.
Owner coverage depends on what the public record carries, so some profiles come back without a name. When that happens the rest of the profile still stands. It is not an error, just a record that does not publish ownership.
The lookup is most useful right before you key a quote, and right before you re-rate a renewal. Some of the ways agencies use it:
A few of the prompts our own team uses word for word:
Get underwriting facts for this address before I quote the home.
What do public records show for the property at 118 Cherry St? Is it owner-occupied?
Pull the property at 4012 Elkins Ave, Nashville. I need year built, square footage, roof and construction for the ACORD.
It is worth being clear about the limits, because they are deliberate.
The year built is a public record held by the county assessor. Most counties post it online, but every site is different, and many search by parcel or owner rather than address. The Property Data Lookup skill returns it from multiple record sources for any US address and tells you whether they agree.
Yes. The profile includes the owner name, owner type (individual, LLC, trust) and owner mailing address where the public record carries them. That is usually enough to tell an owner-occupied home from a rental or a second home before you pick a policy form.
Yes. It uses national property record sources that cover all 50 states, so there is no per-state or per-county setup. The same prompt works in Tennessee, Texas and Ohio.
No. Property lookups are included in the Agency Skills Library subscription. There is no data account to open and no API key to configure. It works the moment the skill is installed.
It shows the roof type (composition shingle, metal, tile, and so on) and a year renovated when the record has one. Roof age itself is rarely in public property records. For that, you still need a permit search or the client.
Carrier prefill only works inside that carrier's portal, and it gives you one number with no indication of where it came from. This lookup runs before you pick a carrier, works for every quote, and labels each field as confirmed or unconfirmed so you know which numbers to trust.
Property Data Lookup is one of the skills in the Agency Skills Library, a set of Claude skills built by working insurance agents for the tasks that eat an agency's day: property lookups, ACORD forms, comparative rating, proposals, VIN decoding, management system connectors and more. One flat subscription covers your whole agency and every skill in the library, including the property data itself.
