How Your Realcomp IDX Website Works
Realcomp is Michigan’s largest REALTOR®-owned MLS. Because your OSI IDX website connects directly to that feed, there’s no delay and no third-party middleman standing between you and your listings. Whether you farm Oakland County or work listings across metro Detroit, your buyers see the same current inventory you see inside Realcomp. Compare that to other REALTOR® websites, and the difference shows up fast: your listings update sooner, and your brand shapes your site instead of a shared template.

Why Agents Choose OSI IDX
A direct Realcomp feed is only part of the equation. Here’s what sets an OSI IDX website apart from other Realcomp IDX vendors:
- Flat, all-inclusive pricing. One price covers your website, hosting, and your Realcomp 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.
- 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.
Frequently Asked Questions

Your OSI IDX website pulls listings directly from the Realcomp feed and refreshes automatically every 10 minutes, so buyers always see current inventory.

Most sites launch in 5–7 business days, depending on your content and design preferences.
How much does the Realcomp IDX feed cost?
The Realcomp IDX feed is $25/month. See full pricing details
What area does Realcomp cover?
Realcomp serves REALTORS® and brokers across Southeastern Michigan, including Wayne, Oakland, Macomb, and Livingston counties, through seven shareholder REALTOR® Associations.
Is Realcomp the same as MiRealSource?
No – Realcomp and MiRealSource are separate Michigan MLSs. Many Southeastern Michigan brokerages participate in one or both, so it’s worth confirming which feed(s) your office subscribes to before your site launches.
Is Realcomp only for Detroit-area agents?
No – while Realcomp is centered on metro Detroit, its shareholder associations extend coverage into the Thumb region and Livingston County as well.
Realcomp Coverage Area
Seven shareholder REALTOR® Associations own Realcomp, and together they serve brokers, agents, and appraisers across Southeastern Michigan.
