Maplewood, N.J. — For buyers and sellers trying to read the housing market in Maplewood and nearby towns, the standard metric most agents use — absorption rate — may be giving a misleadingly calm picture. A local team has developed an alternative measure that suggests the market is running significantly hotter than conventional data shows.
Mark Slade, who leads Mark Slade Homes with his partner MaryCeu Nunes, created what he calls a “hyper market index” to gauge market conditions in real time. The index compares the number of properties under contract to the combined total of active listings, properties in attorney review, and coming-soon inventory. When under-contracts exceed that combined figure, Slade considers it a hyper market — a condition that strongly favors sellers.
As of late June 2026, the index readings across six tracked towns show significant variation. Livingston sits at 0.8, meaning more active listings than under-contracts. West Orange is at 1.1, Union at 1.3, South Orange at 1.7, and Maplewood leads at 1.9. According to Slade, a reading above 1.0 indicates a hyper market. Maplewood’s 1.9 means there are nearly twice as many properties under contract as there are actively available, a clear imbalance that gives sellers substantial leverage.
Slade pulls his data directly from the Garden State MLS, the primary listing system used by agents in this corridor. He notes that Zillow aggregates from multiple sources, including private and exclusive listings that never appear on the Garden State MLS. This discrepancy means that for buyers and sellers in Maplewood and South Orange, Zillow’s market reads can be materially off from what’s actually happening in the Garden State MLS-driven market they are transacting in. Slade is transparent about the limitation on his end as well: 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.
The percent-over-asking figures reinforce the hyper market readings. 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 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 dynamic from Maplewood and South Orange.
For buyers who are waiting, the numbers suggest that deferring a purchase may be costly. 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 waiting 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.
