How Your PACMLS IDX Website Works
Your OSI IDX website connects directly to the Pacific Regional MLS (PACMLS) feed, giving your visitors real, current listings from across Southeast Washington instead of a stale or third-party database. Whether you work the Tri-Cities, the Lower Yakima Valley, or Whitman County, your site reflects the same inventory your MLS shows you. All OSI IDX real estate websites are built to load fast, rank well, and convert visitors into leads, so you spend less time managing your website and more time closing deals.

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

Most PACMLS IDX websites launch in 5–7 business days, depending on your content and design preferences.

What areas does PACMLS cover?
PACMLS covers five counties in Southeast Washington – Benton, Franklin, Garfield, Whitman, and Yakima – including the Tri-Cities, the Lower Yakima Valley, and the Palouse region around Pullman.
Do I need to belong to one of PACMLS’s member associations?
Yes. PACMLS access requires membership with a participating association – Tri-City, Lower Yakima Valley, or Whitman County Association of REALTORS® – through a participating broker.
Is PACMLS the same as Northwest MLS (NWMLS)?
No. PACMLS is a separate, independent regional MLS serving Southeast Washington. Northwest MLS covers the Puget Sound side of the state, and Spokane runs its own separate system.
