RETS Future Trends and Developments: What to Expect
April 16, 2025
9 minutes
Have you ever wondered how real estate listings get updated across dozens of platforms almost instantly? Behind the scenes, a powerful data standard called RETS (Real Estate Transaction Standard) is what makes this magic happen. But as real estate technology evolves, RETS is facing transformation.
This article breaks down what RETS is, why it matters, and what future trends you should watch - whether you're a first-time homebuyer, real estate professional, or seasoned investor.
What is RETS and Why Does It Matter?
RETS was developed by the National Association of REALTORS® to allow MLS (Multiple Listing Services), brokers, and real estate platforms to share listing data efficiently.
Before RETS, listing updates were manual, delayed, and inconsistent. Thanks to RETS, you could:
- See homes listed this morning on Zillow or Realtor.com within minutes.
- Sync real estate CRMs with MLS data.
- Enable mortgage calculators and alerts using real-time data.
Example: Let’s say you're browsing a 3-bedroom home in Miami on a broker’s site. RETS ensures the same listing also appears on Zillow, Redfin, and the MLS platform with the latest photos, price changes, and status.
But Here's the Challenge…
RETS has been around since the early 2000s. While it served its time well, modern APIs (Application Programming Interfaces) now offer:
- Faster data exchange
- More flexibility
- Better support for mobile and cloud platforms
That’s why RESO Web API (the newer standard) is now taking over.

RETS vs. RESO Web API: A Quick Comparison
Feature | RETS | RESO Web API |
|---|---|---|
| Launch Era | Early 2000s | Mid-2010s |
| Technology | XML-based | JSON / REST-based |
| Speed | Slower sync, batch-based | Real-time, event-driven |
| Mobile Compatibility | Limited | Native support |
| Adoption Trend | Declining | Rapidly growing |
Why it matters for you:
Modern APIs make it easier for apps like reAlpha, mortgage calculators, or listing portals to deliver real-time property data, improving your buying/selling experience.
Emerging Trends in RETS and Real Estate Data Integration
Let’s explore what’s changing and why it matters:
1. Full Migration to RESO Web API
MLSs are gradually phasing out RETS and adopting RESO Web API as a new industry standard.
Impact:
- Faster listing updates
- Better integration with mobile apps
- Enhanced data analytics for pricing, trends, and predictions

2. AI-Powered Listing Enhancement
As Web APIs enable cleaner data access, platforms are layering AI tools for:
- Auto-generating property descriptions
- Enhancing photos and 3D tours
- Predicting days on market or price drops
Example: You may see a home listed on reAlpha with a note:
“Predicted to sell within 6 days. 94% price confidence.”
This insight is driven by AI + structured data from RETS/Web API.
3. Real-Time Inventory Insights
Buyers no longer want weekly updates - they want to know if a listing changed this hour.
Platforms like reAlpha can now:
- Push real-time alerts for price drops
- Update listing status instantly (sold, under contract, available)
- Sync buyer preferences with dynamic inventory

4. Cross-Market Listing Syndication
A major hurdle in the past was MLS fragmentation. One MLS may not talk to another, making cross-region home searches painful.
With APIs replacing RETS, we’re seeing:
- Unified data feeds
- Broader search coverage (multi-county, multi-state)
- Better experiences for out-of-state buyers or investors
Investor Tip: If you're looking for properties in both Texas and Florida, modern APIs give you a seamless inventory view across markets.
5. Better Integration with Mortgage & Title
Imagine a scenario where:
- You find a home
- Your mortgage pre-approval adjusts automatically
- Your title company gets instant listing data
This is becoming possible with Web API-based integrations like those at reAlpha Mortgage, where:
- You get live pricing
- See estimated closing costs
- Unlock a substantial commission rebate by bundling services with reAlpha.

As a great communicator with excellent negotiation skills, I focus more on establishing unbreakable ties between my clients, as opposed to just helping them achieve their real estate dreams. As a representative of both buyers and sellers, I understand how to lead a transaction process to ensure that the needs of both are met. My track record speaks for itself. Since I ventured into the industry in 2013 as a realtor, I have not only helped many buyers land perfect homes, but I have also assisted tons of owners and investors build wealth.
