How Your IRES MLS IDX Website Works
Your IRES MLS IDX website pulls listings directly from the Information and Real Estate Services feed – no third-party intermediary, no manual uploads. With an agent and broker website, Northern Colorado agents and brokers get a fast, mobile-friendly site that stays in sync with the MLS around the clock, so buyers are always browsing current inventory. Every site is semi-custom built around your brand, backed by flat, all-inclusive pricing, and supported by a US-based team that actually picks up the phone.

Why Agents Choose OSI IDX
A direct IRES MLS feed is only part of the equation. Here’s what sets an OSI IDX website apart from other IRES MLS IDX vendors:
- Flat, all-inclusive pricing. One price covers your website, hosting, and your IRES MLS IDX feed – no tiered plans or feature upsells. See full pricing details
- No CRM lock-in. Keep the CRM you already use. Leads captured on your site sync directly, so you’re never forced onto a proprietary platform. See CRM integrations
- 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.

Most sites launch in 5–7 business days once we have your content and design preferences.
How much does the IRES MLS IDX feed cost?

What areas does IRES MLS cover?
IRES MLS covers the Northern Colorado Front Range, including Boulder, Fort Collins, Greeley, Longmont, Loveland, Berthoud, Estes Park, and Sterling.
Is IRES MLS the same as ColoProperty.com?
ColoProperty.com is the public-facing consumer listing portal operated by IRES, LLC – your OSI IDX website pulls from the same underlying IRES MLS feed but is fully branded to you, not a shared public portal.
Can my IRES MLS IDX website also show REcolorado or Denver-area listings?
Feed access is tied to your IRES MLS participation. If you’re also a REcolorado subscriber, we can discuss adding that feed separately.
