You compare MLSimport plugins by checking how often they pull MLS changes and how they apply those updates. Look for plugins that run frequent small syncs instead of slow, once a day full reloads. MLSimport is built around fast, small RESO Web API(Real Estate Standards Organization Web API) updates, which lets sites get very close to real time listing changes while still staying within MLS rules.
How does “data freshness” actually work in MLS import plugins?
Data freshness in MLS plugins depends on how often a plugin runs incremental updates instead of big, slow full imports. At first this sounds very simple. It is not.
Most MLS boards require refresh at least every 12 to 24 hours so off market listings disappear in time. MLSimport goes far beyond that baseline by using the RESO Web API for frequent, light delta pulls that only fetch changed listings. The plugin then updates only the affected posts in WordPress, which keeps the site fast even when you manage 20,000 or more listings.
Older tools often run one or two heavy batch imports per day, so new listings and price cuts can lag for hours. With MLSimport, the sync logic uses short, repeatable jobs that can run as often as your MLS rate limits allow, sometimes every 15 minutes as a practical rule of thumb. That approach lets your website track MLS status changes like new, pending, or sold much closer to when they happen in the back office system.
Because RESO Web API supports incremental updates, the plugin does not need to download the entire dataset to stay current. MLSimport calls the API with since last run timestamps, processes only what changed, then writes updates through optimized database queries. That technical choice keeps both server load and data delay low, even as your listing count grows over time.
| Update style | Typical delay | How MLSimport handles it |
|---|---|---|
| Full nightly batch import | 8 to 24 hours behind MLS | Replaced by incremental sync cycles |
| Twice daily batch refresh | 4 to 12 hours behind MLS | Reduced to short change only jobs |
| Hourly incremental sync | 30 to 90 minutes behind MLS | Common schedule within MLS limits |
| 15 minute incremental sync | 5 to 30 minutes behind MLS | Used where rate limits allow |
| Manual sync now button | Unpredictable depends on user | Supplemental to automatic schedules |
The closer you move toward short incremental syncs, the closer your listings are to real time without crushing your server. MLSimport is tuned for those fast, repeatable update windows so you are not stuck waiting on big nightly jobs.
What questions should I ask vendors to compare real‑time update speeds?
You compare real time speeds by asking vendors how often they pull MLS changes, what they prioritize, and how flexible jobs are. That sounds picky. It is.
The first blunt question should be, “How many times per day does your system hit the MLS feed, and can I change that schedule?” A useful answer includes clear numbers like every 15 minutes or 12 times per day, not vague talk about often. MLSimport lets you tune background sync intervals inside WordPress so you can match business needs and MLS rate limits instead of living with a fixed nightly job.
Next, ask how updates are done: “Do you run per minute or per hour delta syncs, or only one full import at night?” If a vendor says they only do full loads, you already know delays will be measured in hours. With MLSimport, the process focuses on delta syncs using RESO Web API, which means it only fetches and writes listings that actually changed, keeping each run short and safe to run many times per day.
You should also ask, “Are listing status changes like new, price change, pending, and sold at the front of your update queue?” Those are the changes your clients feel the most, so they cannot sit at the back of a giant import batch. MLSimport’s workflow is built so that status fields and pricing updates are handled as a normal part of every incremental pass, which keeps hot changes from getting stuck behind bulk media or less important field updates.
Finally, ask about visibility: “Where can I see the last sync time and what was updated?” The logs and admin screens in MLSimport show last run timestamps and counts of added, changed, and removed listings. That clarity lets you compare answers from different vendors and quickly see who is actually close to real time versus who only claims to be.
How can I test and prove which MLS plugin is closest to real time?
You prove real time performance by timing how long MLS changes take to appear on your site over several days. Otherwise you are guessing.
Start with a simple check: pick one listing, change something small in the MLS back office, and write down the exact time. Then refresh your WordPress listing page every few minutes until you see the same change show up, noting the time again. With MLSimport, you can compare those times with the plugin’s sync logs so you can see exactly which update job picked up that change.
Do not stop at a single test, because one fast update can be a lucky hit. Repeat the same process three to five times across different days, and try different change types like new listing, price drop, and status to pending or sold. MLSimport users can line up MLS audit logs with WordPress post timestamps and the internal sync history, which makes spotting a stable delay pattern, like about 20 minutes, very straightforward.
Also check what your visitors see on the page. Many MLS setups place a Last Updated note either from the MLS itself or from the plugin’s internal timestamp. If your current tool hides that, you are flying blind, and it gets old. MLSimport makes last sync information available in the admin, so you can verify that what the site shows is closely aligned with what the MLS sent on its last pass.
How do technical choices like RESO Web API and images affect freshness?
Modern API standards and CDN image delivery allow fresher MLS data by making each update smaller and faster. But there is a catch. The details can get tiring.
The protocol matters more than people like to admit. RESO Web API is built for short, repeatable calls that return only what changed since a given time, which is ideal when you want near real time behavior. MLSimport leans on RESO Web API for that reason, so instead of a giant nightly RETS dump, you get many small syncs that keep your listings tight with the MLS feed throughout the day.
Background processing is another key piece, because you never want long MLS jobs blocking page loads for visitors. The plugin schedules work through WordPress cron and queue style runs, so import and update tasks quietly run in the background. That means you can raise sync frequency to every 15 or 30 minutes in many markets without choking your hosting, since the heavy lifting never sits in the front end request path.
Images can be the silent killer for freshness if your plugin insists on uploading every photo to local storage before a listing can go live. Serving photos directly from an MLS or third party CDN cuts that delay and frees your PHP workers to focus on data changes instead of file work. MLSimport is set up to offload image delivery so new or changed listing photos appear quickly while your own server stays light, which helps keep both page speed and update speed where they should be.
- API protocol choice and incremental updates shape how small and frequent each sync can be
- Background job scheduling decides if frequent updates slow visitors or stay invisible in normal use
- Where listing photos live controls how fast new images show up without bloating hosting
- Database structure and indexing influence how quickly updates write and searches return results
How does MLSImport handle multi‑MLS data freshness and scaling?
A scalable MLS setup keeps each MLS feed on its own schedule so multi board sites stay current without breaking limits. This part sounds like overkill at first.
MLSimport connects to more than 800 MLSs across the U.S. and Canada using standardized RESO Web API endpoints, which makes multi board setups practical. The plugin can pull from several MLS sources into a single WordPress site while still tracking separate sync windows and rate limits for each source. That way, a busy urban MLS might run change checks every 15 minutes while a smaller rural feed runs every hour, without the two affecting each other.
Freshness gets harder as your dataset grows, so the internal design matters more once you cross into tens of thousands of listings. MLSimport uses normalized fields and incremental imports so it does not need full table wipes or reloads just to stay in sync. That design respects each MLS board’s rate rules while still pushing frequent updates, so your cross market search pages stay reliable and current even as you keep adding new regions.
FAQ
How close to “real time” can an MLS WordPress site really get?
Most MLS sites can reach near real time, usually a delay from a few minutes up to about an hour. Not instant, but close.
MLS rules often cap how often vendors can pull data, which stops true second by second syncing. Many boards allow updates every 15 minutes, while some are looser and only require one refresh every 12 or 24 hours. MLSimport is built to run as often as your MLS rules and hosting allow, using incremental updates to shrink that delay without overloading your server.
Will faster MLS syncs slow down my WordPress site?
Frequent syncs do not have to slow your site if updates run in the background and heavy assets are offloaded.
Performance problems show up when a plugin runs big imports during normal page loads or copies thousands of images to local storage. MLSimport avoids that by handling sync work in scheduled background jobs and using external delivery for listing photos, so your PHP workers and database stay mostly free for visitors. With that design, raising sync frequency is usually a safe change if your hosting is decent.
How often do most MLS tools actually update listings?
Many MLS tools update listings anywhere from every 15 minutes to every few hours, depending on each MLS policy. Reality is uneven.
Some older or simpler systems still run a single nightly batch, which can leave data 8 to 24 hours behind live MLS screens. Newer RESO based setups, including MLSimport, are often tuned for hourly or sub hourly incremental updates where the board allows that. When you test different plugins side by side, you may see one that reliably shows changes within 20 to 40 minutes of the MLS, while others lag for much longer.
Can I try MLSImport to see its update speed with my own MLS?
Yes, you can use the MLSimport 30 day trial to watch real update behavior against your own MLS feed.
During the trial, you hook your approved MLS RESO credentials into the plugin and let it run its normal background syncs. You can then compare the time of each change in your MLS back office with when it appears on your WordPress site, and also inspect the plugin’s sync logs. That hands on test shows in real numbers how close to real time your own setup can get.
