Why Agents Choose OSI IDX
A direct MiRealSource feed is only part of the equation. Here’s what sets an OSI IDX website apart from other MiRealSource IDX vendors:
- Flat, all-inclusive pricing. One price covers your website, hosting, and your MiRealSource IDX feed – no tiered plans or feature upsells. See full pricing details
- Direct MLS data feed. Listings sync straight from your MLS every 10 minutes – accurate, current inventory, not a stale or third-party feed.
- Semi-custom design. Your site is built around your brand, not a one-size-fits-all template shared with hundreds of other agents. Browse sample websites
- Family-owned since 1982. OSI IDX is a product of OSI Express, a family-run real estate technology company with over four decades in the industry – not a VC-backed startup.
- US-based, real support. Talk to a real person on our support team, based in the US, not an offshore call center or a chatbot.

Does MiRealSource cover my area if I’m outside Southeast Michigan?
Yes. Through the Great Lakes Repository data-sharing network, MiRealSource reaches roughly 92% of Michigan’s active listings, giving your site broad statewide coverage beyond its core Macomb, Oakland, St. Clair, and Wayne county market.
Is MiRealSource run by a REALTOR® association?
No – MiRealSource is Michigan’s largest broker-owned MLS, independent of any single REALTOR® association, which is part of why it can offer its platform to other boards across the state.
What is a partner association MLS?
A partner association MLS is a REALTOR® Association’s own MLS that runs on MiRealSource’s Paragon platform under an agreement – it gets MiRealSource’s technology and data standards while keeping its own board, branding, and independent rules. It’s different from a merger; each partner association still operates on its own.
