A business picked a source, signed a contract and moved on. In 2026, that decision has become strategic. Three developments, each moving on its own timeline, are reshaping how companies source and access property information: the spread of AI connectors, tighter privacy rules and changes to how listing data flows out of multiple listing services.\n\nProviders in the property intelligence category, including [SL Data Services](https://www.sldataservices.com), which organizes public records into business-ready property data, now operate where all three meet. For the lenders, investors, insurers and software firms that rely on that data, the changes raise new questions about origin, structure and governance.\n\n**AI connectors move research out of the search bar**\n\nThe way teams query data is changing quickly. The Model Context Protocol, an open standard for connecting AI systems to outside tools and data, has been integrated into Claude, Microsoft Copilot, Gemini and ChatGPT, [according to Campus Technology](https://campustechnology.com/Articles/2025/12/15/Newly-Launched-Agentic-AI-Foundation-Brings-Together-Tech-Giants-for-Open-Source-AI-Development.aspx). In December 2025, Anthropic [donated the protocol](https://www.anthropic.com/news/donating-the-model-context-protocol-and-establishing-of-the-agentic-ai-foundation) to the Linux Foundation's newly formed Agentic AI Foundation, which it co-founded with Block and OpenAI.\n\nFor property data, the practical effect is that more analysis now begins with a plain-language question to an assistant connected to internal and licensed sources. That raises the bar for structure. An AI tool reading inconsistent, duplicated or poorly linked records will still produce an answer, and it may sound confident while being wrong. Businesses evaluating data sources are increasingly asking whether a source is ready to be read by machines, not only by analysts.\n\n*An AI tool reading poorly linked records will still produce an answer. It may sound confident while being wrong.*\n\n**Privacy rules put a deadline on deletion**\n\nProperty records are public, but many of them connect to people. Owner names, mailing addresses and transaction histories sit close to personal information, and regulators have taken notice.\n\nCalifornia offers the clearest example. Under the state's Delete Act, residents have been able to submit a single deletion request through the Delete Request and Opt-out Platform, known as DROP, [since January 2026](https://www.alstonprivacy.com/drop-is-coming-due-what-californias-delete-act-means-for-data-brokers-in-august/). Since Aug. 1, 2026, registered data brokers have been required to access the platform and process those requests at least once every 45 days, [according to the California Privacy Protection Agency](https://privacy.ca.gov/drop-for-data-brokers/).\n\nInformation drawn from government records is treated differently under California privacy law than other personal data, which means compliance often turns on knowing exactly where each field came from. For businesses buying property data, provenance has become a governance question, not only a coverage question.\n\n**MLS rules change what listing feeds show**\n\nListing data has its own shifts. In March 2025, the National Association of Realtors introduced its [Multiple Listing Options for Sellers policy](https://www.nar.realtor/sites/default/files/2025-05/multiple-listing-options-for-sellers-faq-2025-05-21.pdf), which lets sellers delay public marketing of a listing through IDX and syndication feeds while keeping it available to other MLS participants. MLSs had until Sept. 30, 2025, to implement it, and each MLS [sets its own delayed marketing period](https://www.nar.realtor/about-nar/policies/summary-of-2025-mls-changes), including the option of zero days.\n\nThe result is a less uniform listing landscape. What appears in one market's public feeds may differ from another's, and a listing's visibility can depend on choices made by the seller and the local MLS. For businesses that blend listing data with public-record data, knowing which input is which, and what each one permits, matters more than it did a year ago.\n\n**Questions to ask a data source in 2026**\n\nTaken together, the three developments point to a short checklist for any business choosing where its property data comes from.\n\n**•** **Origin.** Is the data drawn from public records, licensed listing feeds or both, and is that clearly documented?\n\n**•** **Structure.** Is it organized consistently enough to work inside automated tools and AI assistants?\n\n**•** **Governance.** How does the provider handle privacy requests and use restrictions?\n\n**•** **Fit.** Does the source match the actual use case, whether investment research, lending, insurance or software?\n\n**The bottom line**\n\nThe 2026 property data market is short not on information but on clarity about where that information comes from and whether it is ready for the tools and rules now governing its use. Companies that treat sourcing as a strategic decision, and that work with providers such as SL Data Services that organize public records into a consistent, business-ready format, will be better positioned as AI connectors, privacy mandates and listing standards keep moving.\n\n© Copyright IBTimes 2026.
