How to Build a Real Estate Website with Live MLS Listings | Airo AI Builder
TL;DR
You can build a real estate website with live MLS listings using Airo AI Builder by connecting an MLS API (like SimplyRETS, Spark, or Bridge) through the Secrets panel. The builder generates property pages with images, pricing, descriptions, and school data pulled directly from the MLS feed. No code required. The full build takes one prompt plus API credentials.
Why Do Real Estate Agents Need AI-Built Websites?
According to an Inman December 2025 survey, 79% of real estate agents believe being discoverable via AI is critical to their success. Corporate brokerage templates don’t differentiate agents in AI search results because the content is duplicated across hundreds of agent pages.
Houston ranks as the second-most diverse large city in the US (WalletHub, 2025). The Houston Association of Realtors supports agents communicating in over 100 languages through their HAR International program. Markets like this need custom sites, not corporate templates that can’t adapt to multilingual audiences or niche positioning.
This build came from a real question in the Airo AI Builder Discord community: how do you integrate real estate listings into a site built with Airo AI Builder?
What Can You Build? A Brokerage Site with Live Listings
The finished product is a fictional brokerage called Magnolia City Homes. The brokerage is fake. The listings are real, pulled live from an MLS database via API.
What Airo AI Builder produced:
- Homepage with live property listings pulled from the MLS database
- Individual property pages with images, pricing, home details, and school information
- API integration with SimplyRETS for MLS data
- Contact functionality that associates inquiries with the specific listing the visitor was viewing
The entire site was built through conversation. No code. No templates imported. Just a prompt describing the business, the API connection, and iterative refinements.
How Do You Connect MLS Listings to a No-Code Website?
Real estate listings live in a shared database system called MLS (Multiple Listing Service). Agents throughout North America access it to see what’s open and available. To display those listings on your site, you need an API connection to an MLS provider.
Traditional options like IDX (Internet Data Exchange) feeds require plugins, iframes, or custom development. With Airo AI Builder, you connect the API directly and the builder generates native listing pages from the data.
For this build, we used SimplyRETS because they provide demo credentials for testing. In production, your agent would subscribe to whatever MLS provider they’re authorized to use in their market (SimplyRETS, Spark API, Bridge Interactive, or any RESO-compliant feed).
Step-by-Step: Connecting the API
- Prompt Airo AI Builder that you want to integrate your MLS provider for live listings
- The builder asks for your API credentials
- Enter your key and secret in the Secrets panel (three dots menu > Secrets)
- Save, and the listings populate live on your site
The credentials are stored securely. Once connected, every listing on your site pulls real-time data from the MLS database.
What Property Data Can You Display?
What shows up on each listing page depends on what your MLS provider makes available through their API. In this build, each listing included:
- Property images (multiple per listing)
- Price
- About the home (description, beds, baths, square footage)
- School information for the area
You can prompt Airo AI Builder to customize the display. Add a mortgage calculator, filter listings by neighborhood, or configure the contact form to automatically reference which property the visitor was viewing. All through conversation.
What Compliance Rules Apply to Real Estate Websites?
Real estate websites are regulated. This is the part most AI builder tutorials skip.
Depending on your market:
- Texas Real Estate Commission (TREC) requires specific disclosures and display standards
- The National Association of Realtors (NAR) has IDX display rules including data attribution and refresh frequency requirements
- Your local MLS board may have additional rules about listing status indicators, broker attribution, and data accuracy
Airo AI Builder builds the site. You (or your agent) are responsible for ensuring the display meets local compliance requirements. The good news: even with compliance requirements, you can get from prompt to functional site quickly and layer in required disclaimers and attributions through follow-up prompts.
What Prompt Do You Need to Start?
The initial prompt included:
- Business type (Houston-based real estate brokerage)
- API integration (SimplyRETS for MLS data)
- What to show per listing (full description, school info, images, price)
- Areas to cover
From there, Airo AI Builder generated the site structure, connected the API when credentials were provided, and laid out the property pages with live data. The color palette was confirmed through a follow-up question from the builder.
If you already have a logo or brand colors, include them in your first prompt to skip that step.
Who Can Use This Approach?
This isn’t limited to Houston brokerages. The same API integration pattern works for:
- Solo agents who want a personal brand site with their own listings
- Teams that need a shared site with multiple agent profiles
- Property managers displaying available rentals
- Commercial real estate firms with portfolio sites
- International agents who need multilingual listing pages
- Brokerages replacing expensive IDX plugin subscriptions
Any business that pulls structured data from an API can use this pattern. Real estate is one of the clearest use cases because the data (listings) already exists in a structured format via MLS.

Frequently Asked Questions
Can I build a real estate website with live MLS listings without coding?
Yes. Airo AI Builder connects to any MLS API (SimplyRETS, Spark, Bridge, RESO-compliant feeds) through its Secrets panel. Property pages with images, pricing, and details are generated automatically from the API data.
How is this different from IDX?
Traditional IDX solutions embed listings via iframes or plugins, giving you limited control over design and layout. Airo AI Builder generates native pages from the API data, so listings are part of your site’s actual content. This is better for SEO and AI discoverability.
Which MLS providers work with Airo AI Builder?
Any provider that offers a REST API. This build used SimplyRETS for demo purposes. In production, use whichever MLS API your brokerage is authorized to access (RESO Web API, Spark, Bridge Interactive, Trestle, etc.).
Do real estate websites have compliance requirements?
Yes. TREC (Texas), NAR, and your local MLS board each have display rules covering broker attribution, listing status, data refresh frequency, and disclaimers. Build the site with Airo AI Builder, then add compliance elements through follow-up prompts.
Can the site update automatically when new listings appear?
Yes. The site pulls data live from the API. New listings appear automatically as they’re added to the MLS. No manual updates needed.
How much does it cost to build a real estate site with Airo AI Builder?
50 free credits to start. The Starter Plan ($9.99/month) includes 150 monthly AI credits, a published site with customizable subdomain, database integration, and the ability to download your code.
Can I build a multilingual real estate site?
Yes. Airo AI Builder supports building in any language. Given that HAR International members speak over 100 languages, this is relevant for agents serving diverse markets.
Is an AI-built real estate site good for SEO?
Yes. Unlike iframe-based IDX solutions, Airo AI Builder generates native HTML pages with unique content per listing. This means search engines (and AI models) can crawl and index each property page individually, improving discoverability.
