Which rental sites publish NYC apartments first?

Every NYC apartment hunter eventually asks the same question: which site should I actually be watching? To answer it with data instead of folklore, we tracked every rental listing we could find across 20 platforms, from StreetEasy, Zillow, and Craigslist to the aggregators, brokerages, and corporate-landlord portals, and matched them to a single apartment by building address and unit. Six weeks of peak season, June 1 to July 14: 50,130 apartments, over 1,100 a day.

The short answer: there is no right site. StreetEasy carried 77.1% of everything. That's the most by far, and it still leaves the biggest site in the city blind to almost a fourth of the market. Zillow carried less than half. And 51.3% of all apartments appeared on exactly one site.

How to use this finding

1. Start with StreetEasy for the broadest single-site coverage and the largest share of first observations.
2. Add OpenIgloo and Craigslist because each contributed meaningful first and exclusive inventory in this sample.
3. Check the relevant landlord portals for buildings you would rent in; their smaller feeds were often highly exclusive.

Caveat: this is an observed June–July 2026 sample, not a permanent platform ranking. Coverage can change, private and off-market rentals are absent, and sources without reliable unit numbers or timestamps receive more conservative overlap or speed treatment.

The chart's real story is in the dark segments. Zillow is enormous but adds little unique: 91% of what it carries is also somewhere else. The exclusives live at the extremes, with StreetEasy on one end (38% of its listings appear nowhere else) and the small feeds everyone skips on the other. 69% of OpenIgloo's inventory never appeared on any other site, and the corporate-landlord portals (Avalon, Glenwood, StuyTown) run 75–93% exclusive.

And it isn't a geography artifact. Restrict the comparison to Manhattan, every platform's home turf, and the ranking barely moves: StreetEasy 75%, Zillow 49%, OpenIgloo 15%, RentHop 9%, with 43% of apartments still on exactly one site. RentHop's Manhattan tilt is its own, not our lens: by its own borough pages it lists 7,272 Manhattan apartments against 84 in the Bronx.

Stacking sites is the only real fix

The two biggest sites in the city, watched together diligently, still missed nearly one in five apartments: 9,241 of them in six weeks. Real coverage starts at five sources, and the marginal ones are exactly the scrappy feeds nobody enjoys refreshing.

Fix the clocks, and the speed race flips

Our first pass ranked speed by each site's own displayed timestamps, and Zillow appeared to break listings a day before everyone else. That result is what led us to the timezone bug described in the correction above: Zillow's stamps ran 4 to 22 hours ahead of the moment its listings could actually be found. Measured by real visibility, the race looks like this:

So the giant is also the quick one: three-quarters of the market (75.5%) is findable on StreetEasy within 24 hours of surfacing anywhere, versus 40% on Zillow. Here's where you'd actually have seen each apartment first:

Even so, the biggest site is still not the first place you'd have seen 3 in 10 apartments, and the sites carrying those first looks (OpenIgloo, Craigslist, the landlord portals) are the ones nobody refreshes. Per site, across everything it cross-listed:

Two things fall out of the corrected table. First, Zillow is a fast mirror, not a source: it originates almost nothing, but it catches up on shared inventory in about an hour, which makes it a fine second screen and a poor early-warning system. Second, the genuinely slow feeds are the ones holding exclusives: Equity's portal surfaces its own buildings roughly 13 days after they appear elsewhere, RentHop runs about 5 days behind, and the brokerage sites publish dates without times, so half their races end unresolved. The market's first looks are scattered across the sites nobody checks hourly. That's the structural reason apartment hunting here feels like a part-time job.

There's a right time to look

• Monday–Wednesday is when inventory drops. Over half of new listings post in those three days, and weekends are dead on every site. (The original version reported a big Zillow Sunday spike; that turned out to be the timestamp bug, not renter-relevant behavior.)
• Landlord portals post before breakfast; aggregators after lunch. TF Cornerstone's feed runs at ~2:40 AM (99% of it on Thursdays and Fridays), Equity at 6:42 AM, StuyTown and Avalon by 8:40 AM. StreetEasy's median post lands at 1:45 PM.

Each site is a different market

Hold the borough constant and the sites still price like different cities. Median Manhattan asking rent, same six weeks:

Craigslist sits in its own universe because it carries what the aggregators never see: rooms, sublets, and small-landlord units. 41.7% of its listings asked under $2,500, versus 9% on StreetEasy. It's still the best budget source in the city, and the one that demands the most scam-vetting. It's also the outer-borough king: half its listings are in Brooklyn and 29% in Queens, the Bronx, or Staten Island, while RentHop, OpenIgloo, CitySnap, and KWNYC are ~70% Manhattan. At the other end, the white-shoe brokerage feeds (Douglas Elliman, Brown Harris Stevens) are tiny and skew ultra-luxury, with top asks reaching $125,000 a month.

And the cheaper the apartment, the worse a single-site search performs. Among the roughly 5,300 apartments asking under $2,500, 77% appeared on exactly one site. StreetEasy carried about two-thirds of the segment, Craigslist about a quarter, and they barely overlap. The renters with the least room for error are searching the most fragmented slice of the market.

One myth worth retiring: RentHop advertises about 10,000 active NYC rentals, but almost all of that standing stock is reposts and syndicated inventory that appeared elsewhere first. It carried 5.2% of the summer's apartments and trailed other sites on 82% of what it shared, by a median of five days. A big catalog is not the same thing as fresh inventory.
