The standard measure most agents use to read a real estate market looks backward. Absorption rate – closed sales divided by active inventory – tells you what happened over the past six months. In a market moving as fast as Maplewood, NJ, that number is already stale by the time it lands. For nearly 17 years, one Essex County team has been tracking the commuter markets across Essex and Union County on a weekly basis using a different measure entirely, and what it’s showing right now is a market with significantly more momentum than the conventional data suggests.

Mark Slade, who leads Mark Slade Homes, with his partner–MaryCeu Nunes–developed the measure he calls a “hyper market index” as a way to read market conditions in real time rather than in retrospect. The index compares the number of properties currently under contract against the combined total of active listings, properties in attorney review, and coming-soon inventory. When under-contracts exceed that combined figure, Slade calls it a hyper market.

What the Hyper Market Index Actually Measures

The logic is straightforward: under-contracts reflect recent decisions buyers have made to buy a home, with the vast majority of the deals being made in the past one and a half to two and a half months ago.  In comparison, the Absorption rate out undermines the immediacy and, especially at the turn of the year, can factor in performance that isn’t indicative of the current market.  As an example, if the market had a slow December and a strong March, absorption rate averages them together. The hyper market index doesn’t. It shows where the market is at this moment, which is what actually matters when a seller is deciding whether to list this week or next month, or when a buyer is deciding how aggressively to offer.

As of late June 2026, the index readings across Slade’s six tracked towns break down as follows: Livingston at 0.8, meaning more active listings than under-contracts; West Orange at 1.1; Union at 1.3; South Orange at 1.7; and Maplewood at 1.9. Slade views the turning point as any reading above 1.0 as a hyper market. Maplewood at 1.9 means there are nearly twice as many properties under contract as there are actively available, a significant imbalance that shows that the current deals far outweigh the available inventory and this imbalance favors sellers.

Why Zillow’s Numbers Tell a Different Story

Slade pulls his data directly from the Garden State MLS, which is the primary listing system used by agents operating in this corridor. Zillow aggregates from multiple sources, including private and exclusive listings that never appear on the Garden State MLS, which means the two datasets are not measuring the same thing. The discrepancy isn’t a matter of one being more sophisticated than the other – it’s a matter of what each is actually counting.

For buyers and sellers in Maplewood and South Orange, the practical implication is that Zillow’s market reads can be materially off from what’s actually happening in the Garden State MLS-driven market they’re transacting in. Slade is transparent about the limitation on his end too: if a Maplewood home is listed on the NJ MLS rather than the Garden State MLS, his data won’t capture it. But for the market his clients are operating in, the Garden State MLS data is the most relevant one.

What the Numbers Mean for Each Town

The percent-over-asking figures reinforce what the hyper market readings suggest. As of the week ending June 21, Maplewood’s average sale price is running at $1,323,000 – up roughly $220,000 from where it ended 2025 – with properties selling at 16.1% over asking on average. South Orange is at 15.5% over asking, up significantly from 10.5% at year-end 2025, with an average price of $1,221,000. Both towns ended last year below their current hyper market readings, with South Orange actually below the hyper threshold at 0.7 in December.

The outlier in the group is Livingston, which has the second-highest average price at approximately $1,350,000 but the weakest percent-over-asking result at 2.9%. Its hyper market ratio of 0.8 means supply is outpacing buyer commitment – a different market dynamic to the one playing out in Maplewood and South Orange, and one Slade connects directly to how inventory is being handled there.

What This Tells Buyers Who Are Still Waiting

The case for waiting in this market is harder to make than it might appear. In Maplewood, where the average sale price has risen roughly 22% since the end of last year and properties are consistently closing well above asking, the cost of deferring a purchase compounds quickly. Slade’s position is direct: in a market where demand is running at nearly twice the available supply, buyers who sit out are not preserving optionality – they are watching the entry point move further away.
