Alesco Data's homeowner and mortgage dataset, live on BigGeo, gives mortgage lenders and refi brokers loan-level targeting built on verified equity position, current loan attributes, and property value signals. Stop working lists that were built for someone else's market and start reaching the homeowners who have a financial reason to call you back.

Most data vendors sell you a national license to millions of records you will never contact. BigGeo works differently.You tell us where you sell, and we cut you exactly that geographic slice of the dataset. A single city.
A cluster of ZIP codes. A metro area. A county. Whatever matches your territory. The result is a lean, CRM-ready file containing only the companies in the markets you actually work, delivered at a fraction of the cost of a full national license.

Mortgage lenders and refi brokers are losing originator hours, marketing budget, and borrower relationships every day to the same root problem: prospect lists that do not know what a homeowner's loan actually looks like right now. The rate environment has changed, equity positions have shifted, and the homeowners worth calling are buried inside a list full of people who refinanced 18 months ago or have nothing to tap. That is not a volume problem. It is a data problem.
Access loan balance, origination date, and loan type per homeowner record so your team can instantly filter for the rate vintages and balance ranges that match your current product. No more calling people whose loan profile makes a refi economically pointless.

Equity estimates tied to current property value data let you target cash-out refi candidates with precision. Build segments around minimum equity thresholds and hand your loan officers a list where every name on it has something to work with.

Current property value data anchors every equity calculation to real market conditions, not purchase-price assumptions from years ago. When a market has appreciated sharply, you see it in the data before your competitors do.

Because the dataset lives on BigGeo's DGGS-indexed spatial layer, you can filter and segment by geography instantly. Draw a territory, define a market boundary, or score opportunity density by ZIP and census tract without exporting a single file or waiting on a GIS team.

BigGeo AI is live in ChatGPT and shipping in Claude, giving your team direct access to governed homeowner and mortgage data through the tools they already use every day. Instead of waiting on a data pull or a GIS analyst, a loan officer or marketing lead can ask a plain-language question and get a spatially grounded answer in seconds, backed by Alesco data, not a model's best guess. For the first time, your targeting questions get answered at the scale of the opportunity, not the scale of the effort.
The Alesco dataset is maintained and cleaned on a regular update cycle so that loan balances, origination dates, and equity estimates reflect current conditions rather than stale snapshots. Inside BigGeo, when a dataset is refreshed, the update flows through the Strata layer automatically, which means your segments and queries reflect the latest data without you having to re-pull or re-process anything.
Yes. Because the dataset includes loan balance, origination vintage, and equity position as separate attributes, you can build distinct segments for each campaign type against the same underlying data. In BigGeo's DataLab, you can define those segments as separate Variants, so each campaign accesses only the records appropriate to its offer without any manual list splitting.
Equity estimates are calculated using current property value data anchored to real market conditions, combined with recorded loan balance information, not just purchase-price assumptions. This means the estimates respond to market appreciation and depreciation rather than sitting frozen at the time of origination. Where property values have moved significantly, the equity signal reflects that movement.
Once you activate the dataset in BigGeo's DataLab, you can work with it directly inside the platform or export clean, filtered segments into your CRM, email platform, or dialing system. BigGeo also supports API access for teams that want to build automated refi opportunity scoring into their existing workflows without a manual export step.
After your access is provisioned, the dataset is live in DataLab immediately, indexed on BigGeo's spatial grid and ready for query. Most teams run their first meaningful segment within the same session. Request a sample below and we will walk you through the data in a 30-minute call so you can evaluate fit before committing to anything.
