Real estate listing alerts
Point SiteMonit at a broker's listings page, a builder's new-development page, or an FSBO board, and get an alert the moment something changes: a new unit, a lower price, a status flip. Built for pages that portal-wide saved searches don't cover well.
Free plan: 5 pages, checks every 15 minutes, no card. Paid plans check as often as every 2 minutes.
Zillow, Realtor.com and most big aggregators block automated monitoring aggressively, and no third-party tool gets around that reliably, ours included. If that's the site you had in mind, use their built-in saved-search alerts instead. Where SiteMonit is genuinely useful is the sites those portals pull data from: local brokerage and agency listings pages, regional MLS-fed portals, builder/new-development pages, and FSBO or Craigslist-style boards. Almost none of those run the same level of bot protection, and that's exactly where a change-monitoring tool adds something a saved search doesn't.
Most agency and MLS-portal sites load listings with JavaScript. SiteMonit renders the page in a real browser first, so it sees what you see, not an empty template.
Select a single price or status badge to track one property, or watch the whole listings grid to catch new units as they're added.
The alert shows exactly what changed, "$489,000" struck through and "$459,000" in its place, or "Active" replaced by "Pending", like tracked changes in a document.
Four steps, about a minute, no code.
Step 1
A brokerage's listings page, one property's detail page, or an FSBO board search results page.
Step 2
Click the price or status badge for one listing, draw a box around the "new listings" grid, or leave it as the full page.
Step 3
Every 15 minutes on the free plan, down to every 2 minutes on paid plans, useful when a hot listing might get an offer within the hour.
Step 4
Email, Telegram, Slack or webhook. The alert links straight back to the page, with the before/after diff attached.
This is the part most alert tools skip. Here's what each audience actually sets up.
Watch a specific brokerage's "new listings" or "just listed" page for your target neighborhood, and select a single price on a listing you're already interested in so you hear about a price cut before it's gone. A minute of lead time on a competitive listing is often the difference between seeing it and touring it.
Point SiteMonit at a few regional portals or investor-friendly FSBO boards and watch for new listings under a price ceiling, or for a status change to "back on market," which often signals a fallen-through deal and a motivated seller.
Track a competing brokerage's listings page for new inventory and price changes, so you know what's moving in your market and can price comparable listings accordingly. See also competitor monitoring for the broader use case.
FSBO listings on Craigslist-style boards move fast and rarely have saved-search alerts of their own. Builder new-development pages add units on their own schedule with no notification system at all. Both are good fits for a page-level watch.
Listing pages are noisy: rotating "featured agent" banners, a live visitor counter, a randomized "similar homes" carousel, a cookie-consent bar. If you monitor the full page, you'll get pinged for all of it. A few habits fix that.
For a single listing, click the price and the status badge specifically. That way an unrelated banner rotation or a "12 people viewed this today" counter never triggers an alert.
For a "new listings" page, draw a box around the results grid itself and exclude the header, ads and footer. You still catch every new card without the surrounding page noise.
A small threshold absorbs one-off rendering hiccups (a lazy-loaded image, a shuffled order) so you're only alerted on changes that look like actual content, not layout jitter.
Say you're watching a three-bedroom listing at $489,000 that's been sitting for six weeks, a classic price-cut candidate.
Paste the listing's detail-page URL, select the price element, set the interval to every 15 minutes (free) or every 2 minutes (paid), and choose Telegram as the alert channel since it's the fastest to notice on a phone.
The moment the listing agent updates the price, a Telegram message arrives showing "$489,000" struck through and "$459,000" in its place, with a link straight back to the listing, no need to keep refreshing the tab yourself.
A saved search on a portal only works inside that portal's own inventory and on its own alerting schedule, often batched hourly or into a daily digest. SiteMonit doesn't integrate with any specific real estate platform: it watches the page itself, so it works on brokerage sites, regional MLS portals, builder pages and FSBO boards that have no saved-search feature at all, and it can check as often as every 2 minutes when timing matters. The tradeoff is that it only knows about pages you point it at, so pairing a portal's own saved search with a couple of targeted SiteMonit watches on the sites that matter most usually covers a market better than either alone.
Does this work on Zillow or Realtor.com?
Rarely, and we'd rather tell you that upfront. Zillow, Realtor.com and similar aggregators block automated monitoring aggressively, and no third-party tool gets around that reliably, ours included. Their own saved-search alerts are usually the better option there. SiteMonit is most useful on local agency and broker sites, regional MLS-fed portals, builder pages and FSBO listings, which are almost never protected that way.
What exactly can it alert me about?
Anything visible on the page: a new listing card appearing on an agency's listings page, a price changing on a specific listing, or a status label flipping from Active to Pending or Sold. You choose whether to watch the whole listings page or one listing's price or status.
How fast are the alerts?
As often as every 2 minutes on paid plans, every 15 minutes on the free plan. In a fast-moving market that's often quicker than a portal's own saved-search digest, which can batch alerts hourly or daily.
Is it free?
Yes, for up to 5 pages with checks every 15 minutes, email or Telegram alerts, no card required. Paid plans start at $9.99/mo for more pages and faster checks.
Can I watch more than one agent or brokerage?
Yes. Each listings page or individual listing is a separate monitor, so you can track several agencies, a builder's new-development page, and a couple of FSBO boards at once, all reporting to the same inbox or Telegram chat.
