Get Your Hattiesburg Area Association of REALTORS® (HAAR) IDX Website
A fast, modern real estate website with a direct HAAR data feed – built for agents and brokers across Mississippi’s Pine Belt.

A fast, modern real estate website with a direct HAAR data feed – built for agents and brokers across Mississippi’s Pine Belt.
If you’re a REALTOR® or broker in the Hattiesburg Area Association of REALTORS® (HAAR), your website should show the same listings your clients see everywhere else – not a delayed or partial feed. OSI IDX connects directly to HAAR’s data feed, so your site refreshes automatically every 10 minutes with accurate, current inventory across the Pine Belt.
Your site is more than a data feed, though. It’s a fully branded, semi-custom real estate website for REALTORS® built around your name and your market – not a template shared with hundreds of other Pine Belt agents. Flat, all-inclusive pricing means no surprise upsells, and if you ever need help, you’re talking to a real person on a US-based support team.
Trusted by 1,000+ REALTORS® & Brokers
A direct HAAR feed is only part of the equation. Here’s what sets an OSI IDX website apart from other HAAR IDX vendors:
How often does my HAAR IDX website update with new listings?
Your OSI IDX website pulls listings directly from the HAAR feed and refreshes automatically every 10 minutes, so buyers always see current inventory.
How long does it take to launch my website?
Most HAAR IDX websites launch in 5-7 business days once we have your content and design preferences.
How much does the HAAR IDX feed cost?
The HAAR IDX feed is $25/month. See full pricing details
Will my website reflect the look and feel of the Pine Belt?
Yes. Our design team builds your site around your own brand and photography, layered with professional imagery and video that showcase the Hattiesburg area and the surrounding Pine Belt.
Does my HAAR IDX website cover the whole Pine Belt region?
Yes. Your site covers HAAR’s full service area – Forrest, Lamar, Marion, Perry, and Covington Counties, with reach into parts of Jones and Pearl River Counties.
How does my website connect to HAAR’s listing data?
Your OSI IDX website connects directly to the Hattiesburg Area Association of REALTORS® data feed, and your listings go live automatically once your membership is verified.
Your HAAR IDX website is built for South Mississippi’s Pine Belt region. HAAR’s primary service area covers Forrest, Lamar, Marion, Perry, and Covington Counties, with reach extending into parts of Jones and Pearl River Counties – from Hattiesburg and Petal out to Columbia, Laurel, Poplarville, and the surrounding communities agents and buyers already know.
