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