BatchData launches Buy Box API to match sellers with likely cash buyers

BatchData has released Buy Box API, a new tool that identifies investors most likely to buy a property based on their past transactions, then returns contact details and portfolio history. The launch aims to replace manual buyer searches for wholesalers, agents, builders and software platforms serving real estate sellers.

Why it matters: - BatchData is trying to solve a long-standing gap on the selling side of real estate: finding a buyer quickly after a property is under contract. - The Buy Box API is designed to turn buyer matching into a data workflow instead of a spreadsheet, relationship list or manual group text. - The tool could help sellers assign deals faster, reduce fallout from expired contracts and make buyer outreach more systematic.

What happened: - BatchData launched the Buy Box API today. - The product takes a property address and returns investors most likely to buy it based on what those investors have actually purchased. - Each match includes phone numbers, email addresses and portfolio history so outreach can start the same day. - The API is available now to property-selling companies and to software platforms that serve them. - BatchData also said teams can receive results as data files or use its managed data services. - Platforms can embed the product and deliver it under their own brand. - BatchData is expanding investor classification by type, recent activity, investment focus and geography. - More information is available through BatchData's sales contact page.

The details: - BatchData's Investor Pulse Q1 2026 report says investors made roughly 32% of all U.S. home purchases in the first quarter, the fourth straight quarter above 30%. - The report counts about 16 million investor-owned single-family homes in the U.S. - More than 96% of those homes are held by investors who own 10 properties or fewer. - About 40% of investor sales go to another investor, according to the report. - Buy Box starts with the property that needs to sell, then finds nearby homes that look like it using the same property-matching technology behind BatchData's Property Comparables product. - The system then returns the investors who own those homes or have bought and sold them. - Buyers can be ranked by portfolio size or by other user-selected signals. - The investor profile includes how many properties the buyer owns, how many were bought in cash, how many were purchased in the last 12 months and how long the buyer typically holds. - The contact record also shows whether a phone number has been reached recently. - Do Not Call and litigator flags are attached to each contact. - BatchData said the product uses the company's existing nationwide transaction and ownership infrastructure. - Results come back in the same standard investor profile format many BatchData customers already use.

Between the lines: - BatchData is betting that seller-side data is as valuable as buyer acquisition data, especially in investor-heavy housing markets. - The company is also positioning Buy Box as a replacement for proprietary matching scores that can be hard to explain to sales teams and platform customers. - The approach favors transparency: buyers make the list because they already own or have traded similar properties, not because of a hidden compatibility model. - For software vendors, the product lowers the need to build and maintain their own buyer graph, which BatchData says would take years. - The launch targets multiple user groups at once, including wholesalers, fix-and-flip investors, agents, brokers, builders, iBuyers, institutional sellers, landlords and portfolio owners.

What's next: - BatchData plans to keep expanding its investor classifications so users can target buyers directly, not only through a specific property. - The company says the long-term goal is to make buyer discovery fast enough that sellers can identify and reach likely buyers the same day. - Platforms that already serve sellers can add Buy Box as a branded feature rather than building the capability themselves.

The bottom line: - BatchData wants to make buyer matching a searchable data problem, and Buy Box is its first public attempt to bring that workflow to real estate sellers and the software they use.
