What MLS sync should actually cost in 2026
The pricing is opaque on purpose. Here's the real picture.
Multiple Listing Service integration — the thing that lets buyers search every active listing in your market on your site — is the single most confusing line item in agent-website pricing. It shouldn't be. Here's the real picture in 2026, board by board, vendor by vendor.
The four ways to get MLS data on your site
- RESO Web API direct. The modern standard. Every major U.S. MLS now exposes a RESO-compliant feed. Set up once, you own the feed.
- Aggregators (Spark / FBS, Bridge Interactive, MLSGrid). A layer in front of RESO that normalizes feeds across boards. Saves engineering time.
- IDX widget vendors (iHomefinder, IDX Broker). Drop-in widgets. Easy to deploy, expensive over time, and your data lives on their servers.
- Direct via your brokerage. Some brokerages provide an aggregated feed to all their agents. Free, but quality varies wildly.
What you actually pay
Real 2026 numbers from across our clients:
- RESO Web API: Usually $0 board-side (the MLS itself doesn't charge for the feed if you're a board member). You pay your developer for the integration once — typically $1,500–$5,000 — and that's it. We include this in every Broker.Sale plan.
- Spark Platform: $99–$149/mo. Most popular aggregator. Reliable.
- Bridge Interactive: $149/mo, requires Zillow Premier Agent in some markets.
- iHomefinder: $39.95/mo entry, $99.95/mo full. Cheap but the widget is dated and the SEO penalty for offloading content to their domain is real.
- IDX Broker: $59.99/mo entry, $99.99/mo platinum. Same shape as iHomefinder.
The hidden cost: SEO leak
When you use an iframe-based IDX vendor, the listing pages live on their domain. Every search-engine visit to a listing page lands on idx-broker.com or ihomefinder.com, not yours. You're paying for traffic you don't own. RESO Web API direct (or a server-rendering aggregator) puts every listing under your domain — and the SEO compound interest of that adds up fast.
What Broker.Sale includes
Every Broker.Sale plan — even Basic — includes:
- RESO Web API integration with your MLS board.
- Server-rendered listing pages on your own domain (SEO captured).
- Schema.org RealEstateListing markup baked in.
- Refresh frequency that respects your board's rules (most are 15-min syncs).
- Compliant display logic for each board's specific disclosure requirements.
If your board offers a feed (every major U.S. board does), we wire it up during onboarding. No extra fee, no monthly add-on.
The detection trick
The signup wizard automatically detects which MLS board you're likely on from the markets you list. Type "Aspen, Colorado" and we know you're on the Aspen-Snowmass MLS plus REcolorado for Denver-metro listings. Type "Manhattan, NY" and we know REBNY RLS is your primary board. Twenty-eight boards mapped today, growing weekly. Try it.
