Choosing a Real Estate Website and IDX Platform: What to Check Before You Switch

Start with the job you need done

Choose the main reason you are considering a change:

• Build or improve a branded website. You want a better way to present your business, services, listings, or local expertise.
• Add IDX search and property listings. Your site works, but it needs property search or listing information.
• Capture and follow up with leads. You need inquiries to reach the right person and trigger the right next step.
• Replace or connect marketing tools. You are considering changes to forms, CRM, lead routing, email or text follow-up, or reporting.
• Support a team, brokerage, or individual agent. Your setup needs to fit your users, assignments, branding, and reporting needs.

Keep your choice in mind. The decision guide at the end maps each job to a next step.

Map your current setup before you compare platforms

Trace what happens when someone visits your site, searches for a property, or submits a form. For each step, note the tool and the person responsible.

Then mark each part keep, replace, connect, or unsure. This helps you assess whether a new platform will simplify your tools or create overlapping forms, contacts, alerts, or reports.

A website platform and an IDX layer can solve different problems

A real estate website platform focuses on the site itself and may include IDX. An IDX layer focuses on displaying property search and listing information on a website. These can be separate products, or parts of one platform.

ATG’s AgentFire vs. Luxury Presence comparison compares two website-centered offerings with different positioning. It describes AgentFire as a real estate website with built-in IDX, and Luxury Presence as a premium brand and growth platform that includes website and IDX capabilities. Review the specific plan and workflow you need before deciding whether either matches your setup.

The AgentFire vs. iHomefinder comparison illustrates a different distinction: a fuller website platform versus a product positioned around adding IDX search and lead capture to an existing site. The AgentFire review and iHomefinder review provide additional context about each product’s current positioning.

These examples can help you frame the decision, but they do not determine which MLS, integrations, or workflows will work for your business. The broader Real Estate Software Comparisons page includes these and other side-by-side comparisons.

Check MLS coverage and local requirements

NAR describes IDX as a policy that lets MLS participants authorize limited electronic display of listings by other participants. Your MLS and broker can tell you which requirements apply to your account and market. Because MLS rules vary, confirm coverage, approval steps, and any related fees before choosing a platform. See the checklist below for the questions to ask.

Ask vendors to demonstrate the full lead path

A demo should show what happens from a visitor’s first action through the CRM—not just a homepage or search page.

Ask the vendor to walk through a realistic example:

1. A visitor searches for a property and saves a search or requests information.
2. The visitor submits an IDX inquiry or site form.
3. The inquiry is assigned under your routing rules.
4. The right agent receives a notification.
5. The contact and relevant activity appear in your CRM.
6. Your follow-up emails or texts start, or you confirm another tool will handle them.
7. You can report where the lead came from and what happened next.

If possible, use your actual CRM and a representative example of your routing rules. Ask which fields and activities transfer, how quickly they sync, whether a separate plan or connector is needed, and what happens if the connection fails.

Vendor-demo checklist

Start with the six questions marked Priority. Then use the follow-up questions to clarify what is included.

1. MLS and IDX — Priority

• Is my specific MLS supported for the product, account type, and display I need?
• Who handles MLS approval and paperwork?
• What MLS or data fees may be added to the platform cost?
• Which search features and listing fields are available in my market?

2. Leads and CRM — Priority

• Can you demonstrate an inquiry moving from the site into my CRM and through my assignment rules?
• Which contact details and activity data transfer?
• What notifications are available, and what happens if a sync fails?
• Can my current email or text tools handle follow-up, or would I need to change them?

3. Existing tools and integrations

• Does the platform connect with my current CRM, forms, email or text tools, analytics, and reporting?
• Is each connection included, or does it require an add-on, separate plan, or third-party connector?
• Can you show the integration working with my account or a comparable setup?

4. Migration and ownership — Priority

• Which pages, articles, images, forms, old page links, and page titles will be moved?
• Can existing leads, saved searches, alert subscriptions, and contact records be transferred?
• Who owns my domain, site content, design files, and lead data?
• If I leave, what can I export, what remains usable, and what stops working?

5. Setup, timeline, and support

• What do I need to provide, and what will the vendor configure?
• What is the expected timeline, including MLS approval and content review?
• What training is included, and who can attend?
• Who handles ongoing site, listing, and integration maintenance?
• What support channels and hours are available, and which issues do they cover?

6. Total cost and contract — Priority

Ask for a written estimate that separates:

• Setup or design fees
• Onboarding or migration services
• Hosting and recurring platform fees
• IDX, MLS, or data-feed charges
• User or agent seats
• Add-ons and third-party integrations
• Optional marketing or managed services
• Renewal, cancellation, and early termination terms

Compare the full cost for the period you expect to use the system, not just the headline subscription. Confirm which features are included in the quoted plan and whether fees change with users, markets, leads, contacts, or listing feeds.

Decision guide: choose your scope before you switch

• Build or improve a branded website: Compare website platforms that fit your design and content needs. Confirm IDX coverage, CRM handoff, migration, and ongoing responsibilities.
• Add IDX search and property listings: If your current site works, evaluate IDX options that support it and fit your lead-capture and CRM needs.
• Capture and follow up with leads: Review your forms, routing, notifications, and CRM first. A new website alone may not fix a follow-up problem.
• Replace or connect marketing tools: Map each workflow you expect to move. Ask the vendor to demonstrate it and identify what will remain in your current setup.
• Support a team, brokerage, or individual agent: Confirm user roles, assignment rules, shared reporting, branding, and how the system handles staff changes.

Before switching, ask: What specific problem will this change solve? Which tools will it replace or connect? What work and cost will remain after launch? If a vendor cannot answer clearly, hold off on committing until you have the details in writing.
