Overview

What this migration involves

IDX Broker is primarily an IDX (Internet Data Exchange) platform that lets real estate agents display MLS listings on their websites and capture leads from property searches. It has a basic CRM module for contacts and leads, but its data model centers on listings, saved searches, and lead routing—not the full lifecycle and deal management that growing real estate teams need. HubSpot is a full CRM with contact lifecycle stages, deal pipelines, custom objects, and automation workflows. The migration from IDX Broker to HubSpot requires mapping IDX Broker contacts and leads to HubSpot contacts and companies, translating real estate property data into HubSpot's custom Properties object, and preserving owner assignments through email matching. FlitStack AI extracts data from IDX Broker via their REST API and CSV exports, cleans and deduplicates records, maps every field to HubSpot's property system (including any IDX Broker custom fields), and validates field-level before committing the full migration. Automations, saved search alerts, and MLS feed integrations do not transfer—those require manual rebuild in HubSpot's workflow builder and a new MLS widget integration.

Why teams make this switch

Two sides of the same decision

Leaving

IDX Broker

What's pushing teams away

  • The subdomain-based IDX page hosting (yourwebsite.idxbroker.com) can hurt SEO performance since search engines index the subdomain instead of the agent's own domain, causing some agents to lose organic search equity when switching providers.
  • The MLS approval process requires paper agreements and board sign-off before IDX data access is granted, adding 3-7 days of waiting time that frustrates agents who need quick onboarding.
  • Agents with complex lead management needs find IDX Broker limited compared to full CRM platforms, prompting moves toward solutions like Follow Up Boss, BoomTown, or BoldTrail that combine IDX with pipeline management.

Choosing

What's pulling them in

  • Lowest barrier to entry of any major CRM — the free tier with unlimited contacts lets teams validate fit before committing to a paid plan, according to G2 and Capterra reviewers.
  • Native integration between the CRM and sales engagement tools (sequences, email tracking, dialer) means no separate sync configuration, a theme across G2 Sales Hub reviews.
  • Pipeline visualization, deal tracking, and automated workflows are consistently praised as intuitive and easy to set up without developer involvement.
  • Strong onboarding for new team members — reviewers on Capterra and G2 highlight how quickly new reps become productive without formal training.
  • The HubSpot platform ecosystem (Marketing, Sales, Service, CMS hubs) allows growing companies to consolidate tools without building new integrations.

Object mapping

How IDX Broker objects map to HubSpot

Each row shows how a IDX Broker object lands in HubSpot, including any object-level transformations, lookup resolution, or schema-design dependencies.

Typical mapping — final map is confirmed during the sample migration step.

IDX Broker

Contact (IDX Broker)

maps to

HubSpot

Contact (HubSpot)

1:1
Fully supported

IDX Broker contacts map 1:1 to HubSpot contacts. Name, email, phone, and address fields translate directly. IDX Broker's contact create/update timestamps are preserved as HubSpot custom properties since HubSpot's native CreatedAt is set at migration time. Owner resolution happens via email match against HubSpot users.

IDX Broker

Lead (IDX Broker)

maps to

HubSpot

Contact (HubSpot)

many:1
Fully supported

IDX Broker leads merge into HubSpot contacts. HubSpot has one contact object rather than separate contact and lead objects. The source lead status is preserved as a custom pick-list property in HubSpot, and lifecycle stage is set to 'lead' unless a more advanced stage was tracked in IDX Broker's extended fields.

IDX Broker

Company (IDX Broker)

maps to

HubSpot

Company (HubSpot)

1:1
Fully supported

IDX Broker brokerages and real estate companies map to HubSpot companies. Company name, domain, industry, phone, and address fields translate directly. If IDX Broker stores agent teams as companies, those map to HubSpot teams or companies depending on your target schema.

IDX Broker

Property / Listing (IDX Broker)

maps to

HubSpot

Custom Property Object (HubSpot)

1:1
Fully supported

IDX Broker property records (MLS listings with addresses, prices, MLS numbers, statuses, bedroom/bath counts) require a HubSpot custom object. FlitStack creates the Property object in HubSpot with custom fields for MLS number, listing price, status (Active/Pending/Sold), property type, square footage, and year built. Each property is associated to the relevant contact via a many-to-many relationship.

IDX Broker

Saved Search (IDX Broker)

maps to

HubSpot

HubSpot List

1:1
Fully supported

IDX Broker saved searches are MLS-criteria-based alerts tied to the IDX website engine. HubSpot lists use contact-based criteria and cannot store MLS field logic. We preserve saved search criteria as a custom text property on the contact so your team can manually recreate matching lists in HubSpot.

IDX Broker

Agent / Owner (IDX Broker)

maps to

HubSpot

Owner (HubSpot)

1:1
Fully supported

IDX Broker agents resolve to HubSpot owners by email match. If an IDX Broker agent record has no matching HubSpot user, the record is flagged for your team to either invite the agent to HubSpot or reassign to a fallback owner before migration commits.

IDX Broker

Showing Request (IDX Broker)

maps to

HubSpot

Task (HubSpot)

1:1
Fully supported

IDX Broker showing requests map to HubSpot tasks assigned to the relevant agent/owner. Task subject, property reference, requested date, and contact association are preserved. Original request timestamps and owner assignments carry over. If a showing references a property, the task links to the HubSpot Property__c custom object and task status reflects IDX Broker status (Scheduled, Completed, Cancelled), allowing your team to track showings in HubSpot.

IDX Broker

Note (IDX Broker)

maps to

HubSpot

Engagement Note (HubSpot)

1:1
Fully supported

IDX Broker notes on contacts, leads, and properties migrate to HubSpot engagement notes. Original timestamps, owners, and the parent record association (contact or property) are preserved. Notes attached to specific properties link to the corresponding custom Property object in HubSpot.

IDX Broker

Attachment / File (IDX Broker)

maps to

HubSpot

HubSpot Files

1:1
Fully supported

IDX Broker file attachments (property images, documents, PDFs) are downloaded and re-uploaded to HubSpot Files. Files are linked to the parent contact or Property record in HubSpot. HubSpot's 25MB per-file limit applies; large media files over this threshold are flagged for selective upload.

IDX Broker

Custom Field (IDX Broker)

maps to

HubSpot

Custom Property (HubSpot)

1:1
Fully supported

Any IDX Broker custom fields on contacts, leads, or properties translate to HubSpot custom properties. Field types map: text to single-line text, number to number, date to date/datetime, pick-list to pick-list. Enterprise-only IDX Broker custom objects translate to HubSpot custom objects following the same association rules as standard property objects.

IDX Broker

Lead Source (IDX Broker)

maps to

HubSpot

HubSpot Source Property

1:1
Fully supported

IDX Broker lead source tracking (website form, MLS search, referral, etc.) maps to HubSpot's hs_analytics_source field on contacts. If your IDX Broker uses a custom lead source taxonomy, it migrates as a custom pick-list property and is mapped alongside the standard source.

IDX Broker

Tag / Label (IDX Broker)

maps to

HubSpot

HubSpot Tag

1:1
Fully supported

IDX Broker tags on contacts and leads map to HubSpot tags. Tags are preserved as‑is; HubSpot’s tag model supports the same flat‑label structure that IDX Broker uses for contact classification. During migration, FlitStack AI imports tags exactly as they appear, preserving any hierarchical naming conventions you use. After migration, tags can be used in HubSpot workflows, lists, and reporting for segmentation and automation without any re‑tagging effort.

Pair-specific challenges

  • IDX Broker saved searches have no HubSpot equivalent and must be rebuilt manually

    IDX Broker saved searches store MLS field criteria (price range, beds/baths, neighborhood polygon) tied to the IDX website search engine. HubSpot lists use contact-based criteria and cannot store MLS field logic. We preserve the original search criteria as a text property on each contact so your team knows what to rebuild, but the actual alerts and matching logic must be manually recreated in HubSpot as lists using contact properties rather than MLS fields. This is a structural limitation of migrating from a real estate IDX platform to a general CRM.

  • IDX Broker wrapper pages conflict with HubSpot page hosting and require re-integration

    IDX Broker auto-creates wrapper pages on your website subdomain (e.g., yoursite.idxbroker.com) that display MLS listings with your site's header and footer. HubSpot hosts pages on your portal domain. After migration, the IDX Broker wrapper pages and MLS widget shortcodes on your website will no longer function. You must install a new IDX plugin (IDX Broker, iHomefinder, or another MLS provider) on your HubSpot-hosted or external site and re-add the listing widgets. This is a separate configuration step from the data migration and may require developer support.

  • HubSpot has no native MLS listing object — property data requires a custom Properties object

    IDX Broker's core object is the Property/Listing with MLS fields, pricing, and status. HubSpot has no native listing object. For real estate teams that store active listings as data records (not just contacts with notes), we create a HubSpot custom object called Property__c with fields for MLS number, listing price, status, property type, and address. However, HubSpot custom objects are only available on Enterprise tiers, and creating the schema, associations, and any related workflows requires upfront planning before migration data lands.

  • IDX Broker API rate limits extend data export timelines for large datasets

    IDX Broker's API enforces rate limits on daily and hourly requests. For migrations with tens of thousands of contacts, leads, and property records, we paginate exports across multiple API windows to stay within limits. This extends the extraction phase beyond what a simple CRM-to-CRM migration would require. We monitor rate limit responses and back off automatically, but large IDX Broker datasets (50k+ records) should budget an extra day for the extraction phase.

  • Automations, email templates, and lead routing rules do not transfer

    IDX Broker automations (lead routing, auto-responders, showing confirmation emails) have no direct equivalent in HubSpot's workflow engine. These must be rebuilt from scratch in HubSpot using HubSpot's workflow builder, enrollment triggers, and sequence tools. We export IDX Broker automation definitions as a JSON reference file your team or implementation partner can use to rebuild them. Workflow rebuild is not included in standard migration pricing and should be scoped as a separate implementation project.

Migration approach

Six steps for a successful IDX Broker to HubSpot data migration

  1. Scope and export IDX Broker data via API and CSV

    FlitStack connects to your IDX Broker account via the REST API and exports all contacts, leads, companies, properties, saved searches, showing requests, and notes. For large datasets, we paginate across IDX Broker’s rate‑limited API windows and supplement with CSV exports where available, ensuring complete data retrieval even for high‑volume accounts. During extraction, we capture custom field definitions, tag taxonomies, and owner records to build a full field inventory before mapping begins. This step also identifies any missing critical fields (e.g., contacts without email) for data‑quality review.

  2. Clean data and plan HubSpot schema

    We deduplicate contacts, standardize address formats, and flag records with missing critical fields (no email, no name). For property records, we assess whether your team needs a HubSpot custom Properties object (Enterprise required) and, if so, deliver a schema plan specifying every custom field, pick-list value, and association before migration runs. Owner resolution maps IDX Broker agent IDs to HubSpot users by email match.

  3. Build field-level mapping and create HubSpot custom properties

    Every IDX Broker field maps to a HubSpot property (standard or custom). We create HubSpot custom properties for IDX Broker extended fields, property-specific data (MLS number, listing price, bedrooms), and audit fields (original create dates, source system IDs). For saved searches, we store the criteria as text on contacts. If a custom Properties object is needed, we provision it and its fields during this phase.

  4. Run sample migration with field-level diff

    A representative slice of 100–500 records migrates first—covering contacts, companies, properties, and a few showing requests. We generate a field‑level diff that displays the original IDX Broker value, the mapped HubSpot field, and the destination value for each record, allowing you to verify mapping accuracy and data integrity before the full run. You review the sample in HubSpot, confirm that lifecycle stages, custom property values, and owner assignments meet your expectations, and approve the mapping before FlitStack commits the complete migration.

  5. Execute full migration with delta-pickup window

    Full data migration runs against HubSpot, processing all contacts, companies, property records, showing requests, notes, and attachments in a single coordinated run. A delta‑pickup window (typically 24–48 hours) captures any new or modified records created in IDX Broker during cutover, ensuring HubSpot reflects the final state at go‑live. FlitStack maintains an audit log of every operation, and if reconciliation detects discrepancies, a one‑click rollback reverts the changes for correction. After validation against your source data, your team can start using HubSpot while IDX Broker is decommissioned.

Platform deep dives

Context on both ends of the pair

IDX Broker

Source

Strengths

  • Dedicated IDX platform with broad MLS board coverage across US regions via standardized data feeds.
  • WordPress plugin and drag-and-drop search builder let non-technical agents configure IDX pages without code.
  • Three pricing tiers ($60-$149/month) offer a clear upgrade path as agent volume grows.
  • API access via middleware.idxbroker.com supports custom integrations and data extraction for migration.
  • G2 reviewers consistently rate the platform positively for ease of use and customizable design options.

Weaknesses

  • Subdomain-based IDX page hosting can dilute SEO equity since search engines index the IDX subdomain rather than the agent's own domain.
  • MLS data access requires paper agreement and board approval, adding friction to initial setup and any provider migration.
  • Limited CRM features beyond lead capture — agents needing pipeline management or transaction tracking will need a separate platform.
  • Lead and contact data export capabilities are not prominently documented, making self-service migration difficult.

Destination

Strengths

  • Genuinely useful free CRM tier with no seat limit on contact records.
  • All-in-one sales engagement layer (sequences, email tracking, calling, dialer) embedded natively in the CRM, eliminating a separate integration.
  • Intuitive interface and fast onboarding for individual reps, per G2 and Capterra reviews.
  • Workflow automation triggers across contacts, deals, and tickets with a visual builder.
  • API coverage for all standard objects including custom objects at Enterprise tier.

Weaknesses

  • Pricing model is contact-based at the marketing layer — importing all records as marketing contacts can multiply the monthly bill by 4×.
  • Feature tier cliffs are frequent surprises: sequences, calling, advanced reporting, and quoting are all gated, often requiring plan upgrades mid-implementation.
  • Mandatory onboarding fees at Professional ($1,500) and Enterprise ($3,500) are not prominently disclosed on the pricing page.
  • API rate limits are restrictive for bulk migration — burst limits of 100-200 req/10sec and search endpoint limits of 4 req/sec require careful job queuing.
  • Custom objects, additional pipelines, and advanced forecasting are Enterprise-only, making cost projections difficult for growing teams.
