MLSimport doesn’t include a built-in limit on how many listings you can import or display. Sites already run it on feeds with around 100,000 active properties without a software ceiling. The real brakes come from MLS rules and your hosting plan, which you can upgrade later. If your coverage area grows or your board joins a larger regional MLS(Multiple Listing Service), you can point MLSimport to the new feed without losing your WordPress site or SEO work.
Does MLSimport limit how many MLS listings you can import or show?
The software itself doesn’t cap how many listings you can import or display.
MLSimport is built to take in full RESO Web API feeds, even when “all active listings” means 50,000 to 100,000 properties. There’s no hard coded limit like “up to 10,000 listings” in the plugin. Your real limit comes from your server and MLS rules, not from an artificial number inside this setup.
You also don’t have to bring in everything if you don’t want to. MLSimport lets you filter by office code, city, county, price, property type, or other RESO fields during import. You can start with only your office listings or a few target cities. Later, you can change filters without touching themes, other plugins, or URLs.
Storage stays manageable even with many listings because photos don’t go into the WordPress media library. The plugin stores image URLs from the MLS or its CDN and uses those in property galleries. That cuts disk use when each home carries 20 to 40 photos. MLSimport then creates real WordPress property posts, so every imported listing appears in your theme search, maps, archives, and widgets like a normal post type.
- MLSimport has no hard listing count cap and already runs on feeds near 100,000 active properties.
- You can narrow imports by office, area, price, or more instead of loading an entire board at once.
- Remote image URLs keep disk use controlled even when you pass 50,000 imported listings.
- Each listing becomes a WordPress post, so your theme can show all imported properties.
How does site performance hold up with tens of thousands of imported listings?
With strong enough hosting, even very large listing volumes can stay fast and stable.
Once you pass a few thousand properties, the bottleneck usually moves from MLSimport to your server plan. The docs are pretty blunt that boards with around 100,000 active listings should live on at least a solid VPS, not a cheap shared host. When WordPress gets enough CPU, RAM, and a real cron job, query speed and background syncs stay steady even with hundreds of thousands of property rows.
The plugin’s sync logic matters here. MLSimport uses the RESO Web API on an hourly schedule by default and only asks for changed or new records. It doesn’t try to re-import every listing each time. That drops API calls and database writes, which helps with both MLS rate limits and PHP timeouts. Rough guide: if you can run hourly imports of 5,000 to 10,000 changed records, you’re in safe territory for a board with 50,000+ total listings.
On the front end, you lean on your theme’s performance tools instead of rewriting everything. With MLSimport feeding real posts into WPResidence or a similar modern theme, you can use map clustering, pagination, and search caching to keep results pages quick. Because images stay remote, database growth is mostly text and indexes, which MySQL or MariaDB handle well when tuned. As listing counts climb, you scale hosting, caching, and object cache, while MLSimport keeps doing the same light sync work.
What happens if my MLS coverage area grows but I stay in one MLS?
Growing inside the same MLS mostly means more data through the same setup.
When your board adds new counties or more listings become visible under your same credentials, there’s no rebuild step. MLSimport just sees more records from the same RESO Web API endpoint and creates WordPress posts for them at the next sync. You keep the same settings page, the same API keys, and the same layouts while inventory climbs.
You can also change import filters whenever your coverage plan shifts. Maybe you start with one city and a $300k–$800k price range. Later, you widen MLSimport queries to include nearby towns or a broader budget band as your team grows. Since the plugin writes into one property post type, new listings slide into your existing search forms, maps, widgets, and agent links without new wiring.
Your WordPress and SEO work stays in place while your footprint grows. Existing property URLs, sitemap entries, Yoast settings, and agent profile links keep working as thousands of fresh MLSimport records join the database. If server load rises, you adjust PHP memory, CPU, caching, and cron timing instead of tearing out your IDX setup or changing how listings display.
If my brokerage joins a larger regional MLS, will I have to rebuild everything?
Joining a larger MLS usually means reconfiguring the feed, not recreating your site from scratch.
When your brokerage moves from a local board into a regional MLS, the main change is the data source, not your theme or page structure. You get new RESO Web API credentials from the regional MLS, then update MLSimport connection settings so the plugin reads the new endpoint. Your WordPress site, menu, design, and page templates don’t need to be thrown away, because listings already act as standard posts.
Since every property is a normal post type, your layout, navigation, and SEO plugins keep working after the cutover. You might see a period where old local-board listings age out while new regional listings flow in. During that time, you can use WordPress redirects or SEO plugins to point strong old URLs at new pages. MLSimport’s team also helps adapt field mappings when the new MLS uses different RESO names or statuses, so most of the switch is configuration, not custom coding.
| Change scenario | What you update | What stays the same |
|---|---|---|
| Move from local to regional MLS | MLSimport API endpoint and credentials | WordPress site theme menus structure |
| New RESO field names or statuses | Field mapping inside MLSimport | Property post type search templates |
| SEO preservation during switch | Redirect rules for old top URLs | Sitemap categories main slugs |
| Growing listing count in regional feed | Hosting tier caching cron settings | MLSimport import workflow admin UI |
This pattern means your risk in joining a much larger MLS is mostly about timing and hosting. Not design. You can even keep old imported posts online for a while as “historic” content while new regional data fills in. Then prune or redirect once traffic patterns are clear. With MLSimport handling RESO changes in the background, the switch feels more like a retune than a rebuild, though it never feels zero-effort.
How does MLSimport compare to “hosted IDX” when listing volume grows?
Scaling with this setup depends on your own hosting, not external IDX limits.
Because MLSimport imports listings as native WordPress posts, there’s no SaaS-style cap where a vendor decides how many properties you can index. If you want 80,000 active listings and several years of solds visible, your only constraints are MLS rules and server strength. Hosted IDX tools often keep data off-site and sometimes limit how many properties show on maps or result pages.
Your ceiling with this plugin is tuned by caching, database work, and PHP resources, which you can upgrade step by step. You also keep full control over search layouts, map behavior, and templates as volume grows instead of getting stuck in a fixed external IDX interface. At first that sounds like more work. It isn’t. MLSimport gives you a growth curve shaped by your choices, not someone else’s hard platform limit.
FAQ
Can one WordPress site with MLSimport connect to more than one MLS at a time?
One MLS connection per WordPress site is supported at a time.
MLSimport is designed to connect a single site to a single RESO Web API endpoint, which matches how most boards grant access. If your “regional” MLS is a combined system that already merges several areas under one API, that still counts as one connection and works fine. If you ever needed a second, separate MLS, you’d solve that with another site or a different setup, not by stacking feeds into one plugin instance.
Are there any daily caps on imports or API calls imposed by MLSimport itself?
The plugin doesn’t enforce a daily cap on listing imports or API calls.
MLSimport will request whatever the active sync job and your filters demand, usually on an hourly schedule, without adding its own daily limit. Real limits come from your MLS provider, which might throttle too-aggressive polling, and from your hosting if runs are too heavy. You stay in safe ranges by using incremental update mode instead of trying to re-pull the full feed every few minutes.
What happens to existing imported listings if my MLS renames fields or merges into a new RESO system?
Existing posts stay in WordPress, and you update mappings so new data flows correctly.
When an MLS changes its RESO dictionary or joins a different platform, the records you already imported remain regular posts and don’t vanish. You or MLSimport support then adjust field mappings so new and updated listings keep filling the right fields in those posts. In a full MLS merge, you may also point the plugin at the new API endpoint so future data comes from the new system while old URLs and SEO value stay in place.
Can I start by importing only my office listings and later expand to full-board coverage?
You can begin with a small subset and expand your imported pool at any time.
Many teams start by filtering MLSimport to their own office ID or a narrow city list so they can test performance and layout with a few hundred listings. Once everything looks good, they widen filters to include all IDX-allowed listings in their board without reinstalling or wiping data. The same WordPress property type, menus, and SEO structure hold while the site grows from a small office catalog to full-area coverage.
