The brokerage's legacy web platform relied on outdated RETS sync scripts that ran every six hours. Property listing updates, price changes, and pending status modifications were frequently out of sync with live MLS records, frustrating home buyers and causing agents to present outdated listing data.
Engineering a High-Performance RESO Web API Listing Aggregator for Residential Brokerages
A regional residential real estate brokerage operating fifteen offices required a custom web listing portal to display inventory from four regional Multiple Listing Services (MLS).
Challenge
Solution
FlipWorks developed a high-speed listing aggregation service utilizing the RESO Web API standard. We built real-time event listeners and high-performance caching layers that ingest updated listing records, normalize property attributes across different MLS schemas, and serve instant search queries.
Result
- Accelerated property listing update sync cycles from six-hour batch runs to real-time event updates.
- Standardized property search attributes across four distinct regional MLS databases into a single web portal.
- Improved web search performance, delivering sub-second property search query response times.
