BatchData: Property Data API for Real Estate Professionals
BatchData provides access to a massive database of 155 million U.S. properties, each with over 700 data points, covering 99% of the population. By pulling data from more than 3,200 sources, including county assessors, recorders, mortgage servicers, and MLS feeds, BatchData ensures a steady stream of updates – even during county-level outages.
Features and Capabilities
BatchData’s API offers powerful tools for property data enrichment, delivering details like square footage, year built, tax assessments, open liens, and estimated equity. For skip tracing, it boasts a 76% right-party contact rate, which is about three times the industry average. This is achieved using verified contact information from over 20,000 active feedback sources.
The platform also provides CASS-certified address validation, which cleanses mailing lists by removing duplicates and invalid entries. For bulk operations, BatchData handles millions of records daily, offering delivery via REST API, AWS S3, SFTP, or Snowflake Data Sharing in formats like CSV, JSON, and Parquet.
Real estate wholesalers have reported recovering 30% more contacts from distressed property lists using BatchData’s skip tracing. The platform also includes DNC and TCPA litigator scrubbing, helping users stay compliant and minimize legal risks when running SMS or call campaigns.
These features highlight BatchData’s focus on delivering accurate, actionable data for real estate professionals.
Data Accuracy and Coverage
BatchData ensures 97% overall accuracy through rigorous daily updates and validation processes. Its coverage spans all 50 states and 3,143 counties, with urban areas receiving quarterly refresh rates exceeding 100%. While rural properties make up less than 1% of the database, the platform maintains near-perfect reliability with 99.99% uptime and sub-second response times for real-time queries.
Integration and Developer APIs
The RESTful API, designed for speed and efficiency, supports low-latency GET/POST requests (under 200ms) and uses JSON payloads with OAuth for secure access. Developers can leverage robust SDKs in Python, Node.js, and PHP, along with detailed documentation available through Swagger UI and GitHub.
For high-volume operations, BatchData processes up to 10 million records daily, with enterprise SLAs ensuring consistent performance. Integration with tools like Zapier, N8N, and Make.com simplifies workflows, reducing manual data entry by 80%, which is particularly valuable for agents managing large property portfolios.
With these integration options, BatchData enables real estate professionals to automate tasks and make faster, more informed decisions.
Smarty: Address and Property Data Services
Smarty processes and verifies U.S. addresses against a massive database of over 210 million records, including 20 million non-postal addresses, sourced from more than 10,000 data points. It also provides access to 350+ property attributes spanning structural, financial, and locational details.
Core Features
Smarty excels at standardizing addresses to USPS format, achieving an impressive 99% match rate. Each address is assigned a persistent SmartyKey®, a unique identifier that remains constant even if the address changes. With the ability to process over 25,000 addresses per second, Smarty allows real estate professionals to integrate datasets from multiple sources – like MLS and loan origination systems – without the risk of creating duplicate records.
The property data enrichment service dives deep into property details, offering:
- 150+ structural attributes: Includes square footage, roof material, and foundation type.
- 130+ financial metrics: Covers market value, assessed value, and mortgage loan amounts.
- 60+ locational attributes: Includes structure elevation, zoning details, and parcel boundaries.
Monthly updates ensure the data stays current, reflecting changes like renovations or ownership transfers. For spatial analysis and workflows like risk modeling or property valuation, Smarty also provides rooftop-level geocoding for pinpoint accuracy.
Data Accuracy and Coverage
Smarty’s dataset is updated every month and spans all 50 states, covering both residential and commercial properties. By incorporating 20 million addresses not found in USPS records, Smarty delivers a broader perspective, especially useful for rural or newly developed areas. The SmartyKey ensures that address data remains reliable over time, even as municipal boundaries shift or addresses are reassigned.
Developer Tools and Integration
Smarty makes its platform highly accessible for developers with a range of tools and integrations. These tools are essential for any developer building a real estate API solution. It offers SDKs in nine programming languages (.NET, Go, iOS, Java, JavaScript, PHP, Python, Ruby, Rust) along with no-code solutions like Excel add-ins, Google Sheets add-ons, and a QGIS plugin. Developers can explore functionality using API Playgrounds and detailed Postman documentation.
Additionally, Smarty supports ETag headers, which help reduce costs by returning a 304 status if data hasn’t changed since the last query, ensuring users aren’t charged unnecessarily.
For those interested in trying Smarty, the free trial includes 1,000 lookups with access to all 350+ property attributes. The Professional Plan is available for $350 per year, while custom plans can scale to handle anywhere from 50,000 to over 250 million lookups annually.
Feature Comparison: BatchData vs. Smarty
Property Data and Contact Enrichment
BatchData offers an extensive range of over 700 property data points, including core property details, valuations (AVM), sales history, mortgage specifics, lien balances, and pre-foreclosure data. Its database spans 160 million properties and 360 million property owners. What sets BatchData apart is its proprietary linking logic that reveals the individuals behind LLCs and trusts, a feature essential for real estate investors and commercial teams targeting decision-makers.
For contact enrichment, BatchData delivers verified phone numbers and email addresses with an impressive 99.9% accuracy rate. It also includes daily-updated DNC and TCPA scrubbing, reducing legal risks for marketing teams. Smarty, by contrast, focuses on address standardization and property attributes, offering approximately 350 data points related to structural, financial, and locational information. However, Smarty does not provide skip tracing or contact enrichment services.
Both platforms enhance their data offerings with tools for bulk address verification and delivery, streamlining processes for users.
Address Verification and Bulk Delivery
In addition to its contact enrichment capabilities, BatchData integrates address verification into its broader property intelligence system, maintaining high performance in this area. Users can access data through REST API, Snowflake, S3, or flat file exports. Its pay-as-you-go pricing and custom data extraction options make it a flexible choice for real estate teams handling instant lookups or large-scale market analyses without long-term commitments.
Smarty, on the other hand, excels in fast and accurate address validation that complies with USPS standards. While both platforms provide reliable address processing, BatchData’s broader range of features makes it well-suited for more comprehensive real estate and marketing needs.
Scalability for High-Volume Operations
Both BatchData and Smarty excel in handling large-scale operations, but their strengths cater to different use cases.
BatchData supports unlimited API calls with a 99.99% uptime guarantee and processes over 10 million queries daily. This makes it a reliable choice for real estate firms managing extensive skip tracing campaigns, with response times consistently under 500 milliseconds. The platform’s tiered pricing ensures smooth scalability, accommodating growth from 100,000 to over 3,000,000 records monthly. For enterprise users, BatchData also offers a self-hosted data infrastructure option known as MCP Server, providing additional control and flexibility.
Smarty, on the other hand, leverages a cloud-based system capable of processing billions of validations annually. Its asynchronous batch processing can handle up to 1 million records per hour, with elastic throughput supported by global content delivery networks. Smarty guarantees 99.999% uptime, ensuring consistent performance. Property investment firms report smooth operations when enriching up to 500,000 leads per month without any noticeable slowdown.
While both platforms deliver enterprise-level scalability, BatchData is particularly well-suited for businesses needing detailed property intelligence at high volumes.
Real Estate Use Cases: Property Intelligence and Investment Analysis
Real estate investors and marketers can tap into BatchData’s tools to gain deeper insights into properties and enhance their investment strategies.
Property Intelligence and Market Research
BatchData provides data on 155 million U.S. properties, giving investors the ability to track market trends and identify undervalued properties. With access to ownership records, tax assessments, and sales history, users can create heat maps to visualize appreciation rates in specific neighborhoods. For example, investors can analyze bulk parcel data to pinpoint suburban areas showing 15-20% annual value growth based on historical comparisons.
The platform also monitors critical indicators like pre-foreclosure status, Notices of Default, auction dates, and unpaid balances. This helps investors discover off-market opportunities before they hit the open market. Filters such as estimated equity, Loan-to-Value (LTV) ratios, and Automated Valuation Models (AVM) ensure that potential deals offer solid investment margins. Additional insights, like absentee ownership, ownership length exceeding 20 years, and corporate versus individual ownership, help identify sellers who may be open to below-market offers.
Smarty, on the other hand, specializes in USPS-certified address verification with an impressive 99.99% accuracy rate. By appending latitude and longitude coordinates, Smarty enables spatial analysis, allowing real estate analysts to overlay data onto GIS maps. This often reveals trends such as proximity to amenities that can boost property values by 10-15% in urban areas. While Smarty is excellent for address standardization and market scanning, its ownership insights are less detailed compared to BatchData’s extensive property-specific data.
These insights are further enhanced by BatchData’s skip tracing capabilities, which are key for targeted marketing efforts.
Skip Tracing and Marketing Campaigns
BatchData’s skip tracing API takes property intelligence a step further by aggregating verified contact details, including phone numbers, emails, and owner information, from public records. The tool achieves 85-95% contact match rates, making it highly effective for reaching off-market property owners. Investors using this feature for direct mail and SMS campaigns report 25% higher response rates when sourcing wholesale leads. With access to over 200 million owner records and 92% accuracy for contact appends, BatchData is ideal for large-scale campaigns.
Smarty complements these efforts by focusing on address verification, which can reduce undeliverable mail by up to 98%. Its global autocomplete feature also supports targeted digital campaigns. When integrated with CRMs, Smarty validates contacts in real time, leading to a 30% increase in email open rates for real estate outreach. However, Smarty’s primary strength lies in cleansing and verifying contact lists rather than sourcing comprehensive contact details, making it a great tool for ensuring accuracy in marketing databases.
Feedback from real estate professionals highlights the strengths of each platform. Experts on REI BlackBook forums commend BatchData for its “end-to-end property-to-contact workflows”, earning it a 4.8 out of 5 rating on G2 for its data depth. Smarty, meanwhile, is praised on Capterra for its speed and reliability, earning a 4.9 out of 5 rating, particularly for its “bulletproof address tools.” Investors often choose BatchData for its comprehensive property insights, while marketing teams lean toward Smarty for accurate address validation.
