IDX Coverage

HAR MLS IDX Real Estate Websites.

Add live Houston MLS listings and property search to your website with iHomefinder IDX.

Yes — iHomefinder provides HAR MLS IDX for real estate agents, teams, and brokers who want live property listings and home search on their own website. HAR listings, photos, prices, open houses, and status changes update automatically through the IDX feed — including residential rentals. iHomefinder works with WordPress and other website platforms, or provides the complete website — either way, listings are embedded directly on your domain, no iframes, no subdomains. IDX search, lead capture, CRM, saved searches, and listing alerts are included in one platform.

The Houston Association of REALTORS® is the second-largest local Realtor® association in the United States, serving the Greater Houston metro through its MLS subsidiary, Houston Realtors Information Service (HRIS). You may know it as HAR MLS, HARMLS, or the Houston MLS — same database.

The Houston Question

HAR.com Already Exists — Why Do I Need My Own Website?

Fair question — HAR.com is one of the most successful MLS consumer portals in the country, and it genuinely sends leads to Houston agents. Your own website doesn’t replace it. It does a different job:

HAR.com is the marketplace.

Every Houston agent is on it. Your profile sits alongside tens of thousands of others, and the buyer relationship starts on HAR’s platform, on HAR’s terms.

Your website is your storefront.

It ranks for the neighborhoods you farm, captures leads that belong only to you, feeds your CRM with behavior data — who’s searching, what they’re saving, when they’re ready — and compounds value year over year on a domain you own.

The agents winning in Houston use both: present on the marketplace, building equity in their own storefront. iHomefinder is the storefront — with HAR’s live listing data inside it.

Listing Data

What HAR Listings Can I Display?

  • Active listings —  house, condo, lots/land, multi-unit residential, and farm — updated approximately every 2 hours
  • Open houses — included in HAR IDX; unusual among MLSs and valuable in Houston’s lease market
  • Open houses — dates and times synced from the MLS
  • Status changes — pending, price changes, and back-on-market updates as they post
The Texas Data Shares

Does the HAR Data Share Network Change What’s on My Website?

  • HAR is the only Texas MLS partnered with three others.

    HAR shares data with LERA MLS (San Antonio), Unlock MLS (Austin), and NTREIS (Dallas–Fort Worth) — and HAR subscribers also see 61,000+ international listings across Mexico and Central/South America inside Matrix.
  • What this means for your website: 

     Data shares primarily affect what you see inside Matrix. What displays on your IDX website depends on your IDX feed and each MLS’s display rules. 
  • Working Houston plus another Texas metro?

     iHomefinder supports multiple MLS feeds on one website and in one CRM — HAR + NTREIS, HAR + Unlock, or HAR + LERA. The number of included feeds depends on your plan.
The Platform

What You Get with iHomefinder HAR IDX

Listings on your domain

Property search and listing pages live on your domain rather than a framed page or vendor subdomain — giving you stronger control over search visibility, analytics, and lead capture.

IDX + CRM + automation, one login

Every iHomefinder plan includes IDX, CRM, and marketing automation. When a buyer saves a search in Katy or favorites a townhome in the Heights, that activity appears in your CRM.

Rentals working for you too

With residential rentals in the feed, lease-side clients search on your site instead of a portal — and today’s renters are next year’s buyers, already in your CRM.

Multi-MLS on one site

iHomefinder supports multiple MLS feeds on one website and in one CRM. The number of included feeds depends on your plan.

Works with Follow Up Boss

iHomefinder integrates with Follow Up Boss, automatically forwarding new IDX leads into the CRM your team already uses.

The fastest setup we offer

No IDX paperwork for HAR members — a quick email after signup, approval normally within one business day.

Compatibility

Does HAR IDX Work with My Website?

Yes — three ways. iHomefinder integrates with your existing WordPress site, works with other website platforms, or builds and hosts the complete site. In every case, listings render on your domain, and iHomefinder handles configuration and feed setup — no developer required.
