How to Build a Real Estate Website With WordPress Across Multiple MLS Feeds

Last updated: September 17, 2026

How to handle listings from different MLS regions comes down to one setup: since version 7.2, our MLS Import plugin connects one WordPress install to several approved MLS boards over the RESO Web API. Each board is its own connection, and each connection runs as many import tasks as you need.

Each task filters on property type, status, city, county, ZIP, price range, agent ID, agency ID, or office ID, so one board’s inventory splits across as many task sets as the site plan calls for.

Each board keeps its own credentials, its own field mapping and its own import tasks, so adding a second board never changes the first. How many boards you can connect depends on your plan: 1, 3 or 7.

Before version 7.2, a second board meant a second WordPress install and a second subscription. That is no longer needed. Both boards import into the same site.

For the setup screen by screen, see how to connect two MLS boards to one WordPress site.

Which leaves the question this article spends most of its length on: once two boards feed one site, what does the public see, and what does NAR’s policy let you combine?

Key Takeaways

1. Since version 7.2, MLS Import connects up to seven MLS boards to one WordPress install; your plan sets how many.
2. Each connection runs multiple import tasks, filtered by type, status, city, county, ZIP, price, agent, or office. Each task belongs to one MLS.
3. On our reading of RESO’s field pages, Data Dictionary 2.0 standardizes field names; local values and board rules still vary.
4. NAR Policy 7.58 permits co-mingling two MLSs’ listings when you hold participatory rights in each.

How to handle listings from different MLS regions: one install, one connection per board

Start with the setup: everything else in a two-board build sits on top of it. MLS Import holds one connection per MLS board, and all of them live on the same WordPress install. You add them on the Connections tab in MLS Import Settings, which lists each MLS with its status and the time of its last test. Inside each connection, you create as many import tasks as the site needs.

Know the limits before you plan. A site holds up to seven MLS connections. Each import task pulls from one MLS. And multi-MLS works when listings are imported into WordPress, in standalone mode and with the supported themes. It does not work in the live “store nothing” mode.

Multi-board brokerages aren’t an edge case. RESO’s own MLS FAQ, pulled 2026-08-19, counts 489 MLS systems in the United States as of July 2026, plus more than 30 in Canada.

Two boards on one site means one dashboard, one hourly sync and one site to update. Each board still has its own credentials.

If you’re still weighing a direct feed against an IDX vendor, settle that first. Everything below assumes the access route is decided.

 

How does a brokerage show two boards to the public?

Both boards import into the same site, so your buyers see one site. Two things happen on the public side:

1. One search covers the listings from both boards, on your domain, with your contact forms.
2. A house listed on both boards shows once. MLS Import matches the two listings by street address, unit and city, and shows the copy from the connection that is higher in your priority order. The other copy is hidden, not deleted, and comes back if the shown copy leaves the market.

How the search looks is a template decision. MLS Import’s job stops at the pipeline: connect, filter, import, update, remove.

The legal ground is explicit. NAR’s Policy Statement 7.58 states that an MLS participant “may co-mingle the listings of other brokers received in an IDX feed with listings available from other MLS IDX feeds, provided all such displays are consistent with the IDX rules, and the MLS participant… holds participatory rights in those MLSs” (adopted 11/14, pulled 2026-08-19).

NAR describes who may combine listings, not how the software holds the feeds. Individual MLSs may require that listings from another MLS “display the source from which each such listing was obtained,” which Step 5 covers.

The implementation sequence

Step 1: Get credentials approved separately for each board

Each board approves its own credentials on its own timeline. Two boards, two credential sets. Each set becomes its own connection. Ask for RESO Web API access by name.

Check your board in RESO’s certification registry, whose own chart data (pulled 2026-08-19) counts 314 Certified Current, 77 Passed Current, 7 Certified Legacy, and 132 Uncertified. Passed Current is not “no Web API”: RESO defines it as a system that passed technical testing whose organization has not yet accepted those results for publication as certified. The RESO Web API connection details come from that approval.

Step 2: Add each board as a connection, then split it into import tasks

Add the first board in the setup wizard. Add the second on the Connections tab: click + Add MLS, pick the MLS, enter its credentials, then test and save. Nothing is saved until the test passes.

Inside each connection, each import task filters on property type, status, city, county, ZIP, price range, agent ID, agency ID, or office ID. A task pulls from one MLS, chosen when you create it, and can’t be moved to another MLS after you save it. So a region on the second board gets its own task, with that board’s own city, status and property type values.

Step 3: Normalize the fields to the RESO Data Dictionary

Map every import to the Data Dictionary’s field names, not to your first board’s labels. Each connection has its own field mapping: the Listing Details tab has an Editing fields for selector that switches between boards. DD 2.0 is the current version for RESO certification, approved October 23, 2023 (dd.reso.org, pulled 2026-08-19).

The targets are StandardStatus for listing state, PropertyType and PropertySubType for classification, and the Media resource for photos.

Step 4: Normalize the taxonomies before the first import

Field normalization gets the data in. Taxonomy normalization makes it searchable. Your theme keeps its own property-type categories, and both boards’ values must land in the same ones or your search filters split into near-duplicates.

RESO’s Data Dictionary wiki records 99% usage adoption for PropertyType and 95% for PropertySubType (pulled 2026-08-19). High, and still not the same as two boards populating them identically.

Step 5: Import and display each board’s required attribution

Two clauses of NAR’s Policy Statement 7.58 govern this. An IDX display “must clearly identify the name of the brokerage firm under which they operate in a readily visible color and typeface.” A clause amended 11/21 adds the listing firm plus its “email or phone number… not smaller than the median used in the display of listing data.”

On a blended page, label which board each listing came from; some boards require it. See our notes on MLS display rules, attribution, and internet flags.

Step 6: Set a refresh schedule each board’s rules allow

Each board sets its own refresh rules, so check both boards and meet the stricter one. NAR sets the floor: the IDX download “must be refreshed… no less frequently than every twelve (12) hours” (Policy Statement 7.58, amended 5/17).

Some boards cap the other end: Contra Costa Association of REALTORS states authorized vendors “may pull new listing data up to six times a day” (ccartoday.com, pulled 2026-08-19). Six is a ceiling, not a goal.

Step 7: Don’t run two large first imports at the same time

Both boards now run on the same host, so starting the first full import of each board in the same hour is the failure that costs a weekend. WordPress’s Plugin Handbook says WP-Cron “is only triggered on page load,” and PHP’s manual lists a default max_execution_time of 30 seconds.

So a big job can get cut mid-run, and the front end shows half-updated listings or a stalled queue. Let the first board’s import finish before you start the second, then define DISABLE_WP_CRON in wp-config.php and add a system cron entry. More on avoiding overlapping import tasks.

📌 Pro Tip: check max_execution_time on your host first; no amount of spacing saves a job that dies at 30 seconds.

Step 8: Monitor each feed separately and alert per feed

Check each connection on its own. The Connections tab shows each MLS with its status. If one token expires, only that connection’s tasks pause, the other board keeps syncing, and the failing row shows an Update credentials action. The statuses MLS Import treats as off-market (Closed, Deleted, Expired, Withdrawn) can trigger removal, so a listing that should have dropped and did not is your first signal.

The daily cleanup runs per board. If one board’s API is offline, the plugin skips that board’s cleanup for the day and deletes nothing, so its last synced listings stay on the site. Related: fix outdated listings on a WordPress real estate site.

Worked example: the same three fields across two boards

“Different MLS regions use different field names” is a common misconception. But once both boards are RESO Data Dictionary certified, it’s wrong: standardizing those names is the point of certification. What varies is the values inside them, plus board rules outside the Dictionary. That reading is ours, from RESO’s field pages.

Table 1: status and property type. RESO field names are real and cited; “Board A” and “Board B” are illustrative, not real board values.

RESO defines StandardStatus as “the status of the listing as it reflects the state of the contract between the listing agent and seller.” MlsStatus sits beside it by design, documented as “an open enumeration… Providers may use local values.” That is why normalization exists.

Table 2: photos. Three real boards, three different published rules, each cited to its own page.

Three boards, three different rules on photo count and timing. Read each board’s own rulebook.

What changes from board to board

Opt-in and opt-out participation models

NAR’s model policy makes IDX inclusion the default. MLSs “may not exclude any listings… except those listings for which a seller has affirmatively directed that their listing or their property address not appear on the Internet.”

The listing broker’s side starts from a similar default: consent “may be presumed unless a listing broker affirmatively notifies the MLS that the listing broker refuses to permit display.”

The practical question usually isn’t whether a board “lets you in,” but whether a seller opted a listing out. Presumed consent is a common default, not a universal rule.

Which fields you actually receive

A standardized field name is not a promise that the field is populated. RESO’s Data Dictionary wiki records StandardStatus at 94% usage adoption across 344 organizations (pulled 2026-08-19).

Go a level deeper and the spread widens. RESO’s Data Dictionary wiki puts lookup-value adoption inside StandardStatus at 94% for Active and 23% for Coming Soon (pulled 2026-08-19). Before you build a filter or a badge on any single value, check what that board’s feed actually sends.

Photo and media limits

Photo rules are set per board. MLS Now (Ohio) caps a listing at 50 photos (support.mlsnow.com, March 13, 2026). OneKey MLS (New York) sets a minimum instead: most listings need one front exterior photograph within 24 hours of entry, and photos “may not be deleted” once a listing is no longer Active, with narrow status exceptions (support.onekeymls.com, June 3, 2026). Realcomp II Ltd (Michigan) allows only the primary photo on pending and sold listings (Section 18.10, realcomp.com IDX rules).

Build the gallery to degrade to one image; on a Realcomp feed that’s sometimes all you get.

Refresh timing

Three independently published rulebooks state the same floor in nearly identical words. NAR: refreshed “no less frequently than every twelve (12) hours.” CVR MLS, Section 11.2.5: “at least once every twelve (12) hours.” Realcomp, Section 18.2.5: “at least once every 12 hours. (Revised 2014).”

The ceiling is a separate, local number: CCAR’s six pulls a day. A floor is a minimum you must meet. A ceiling is a maximum you must not exceed, never a target.

Local display rules

NAR’s attribution baseline is the brokerage name plus the listing firm’s email or phone number. Boards add their own layer on top. Realcomp requires that, absent a link through to a detail view, “the Listing Office Name and Originating MLS must be displayed in the summary display for every listing” (Section 18.3.3, realcomp.com IDX rules).

On a two-board site, “Originating MLS” stops being boilerplate and starts being load-bearing.

What MLS access itself costs, board by board, is in understanding MLS access costs. Adding a board to MLS Import is a plan change; see MLS Import pricing.

Frequently Asked Questions

How many MLS connections can one WordPress site have?

Up to seven. Since version 7.2, MLS Import connects several approved MLS boards to one WordPress install, and your plan sets how many: 1, 3 or 7. Each connection has its own credentials, field mapping and import tasks.

How do I set up IDX search to cover multiple regions for a team or brokers?

Create one import task per region. For regions on one board, the tasks use that board’s connection. For regions on a second board, add that board on the Connections tab and create tasks with its own city and status values. All listings land on the same site, so one search covers both.

Do different MLS boards use different field names?

On our reading of RESO’s published field pages, no. StandardStatus, PropertyType, PropertySubType, and the Media resource are Data Dictionary names. What differs is the local values inside them, plus board rules such as photo caps; MLS Import maps every board to the same Data Dictionary targets.

What happens when the same house is on both MLS boards?

Your site shows it once. MLS Import matches the listings by street address, unit and city, and shows the copy from the connection that is higher in your priority order. The other copy is hidden, not deleted, and it comes back if the shown copy leaves the market.

What does MLS Import cost for a brokerage on two MLS boards?

As of September 2026, MLS Import has three plans: Single MLS at $49 per month, 3 MLS at $99 per month, and 7 MLS at $199 per month. A brokerage on two boards takes the 3 MLS plan and runs both boards on one site. Yearly billing saves 15%.

What happens if an MLS listing changes status or goes off the market?

The statuses MLS Import treats as off-market (Closed, Deleted, Expired, Withdrawn) can trigger removal from the WordPress site during the normal sync cycle. If one board’s API is offline, only that board’s tasks pause, its daily cleanup is skipped with zero deletions, and the site keeps its last synced listings.
