A new measure developed by the Mark Slade Homes team reveals that Maplewood, New Jersey's housing market is performing significantly better than traditional metrics suggest. The "hyper market index," created by team lead Mark Slade and his partner MaryCeu Nunes, 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 considers it a hyper market. As of late June 2026, Maplewood's index stands at 1.9, meaning there are nearly twice as many homes under contract as there are available for sale, a clear indicator of seller-favorable conditions.
The standard absorption rate, which measures closed sales divided by active inventory over the past six months, often lags behind current conditions. Slade argues that this backward-looking metric can mislead buyers and sellers, especially during periods of rapid change. For instance, absorption rates average together slow months and strong months, whereas the hyper market index captures the present momentum. This real-time view is critical for sellers deciding when to list and for buyers determining how aggressive to be with offers.
Across the six towns tracked by Slade's team, the index readings vary significantly: Livingston at 0.8, West Orange at 1.1, Union at 1.3, South Orange at 1.7, and Maplewood at 1.9. Livingston, with the second-highest average price around $1,350,000, shows a different dynamic where supply outpaces buyer commitment, reflected in its 2.9% percent-over-asking figure. In contrast, Maplewood's average sale price has reached $1,323,000, with properties selling at 16.1% over asking, while South Orange averages $1,221,000 at 15.5% over asking.
Discrepancies between Slade's data and platforms like Zillow stem from different data sources. Slade pulls directly from the Garden State MLS, the primary listing system for agents in the corridor, while Zillow aggregates from multiple sources, including exclusive listings not on that MLS. This means Zillow's market reads can be materially different from the Garden State MLS-driven market where local transactions occur. For buyers and sellers in Maplewood and South Orange, relying on the most relevant local data is essential.
For buyers considering waiting, the data suggests that deferring a purchase may be costly. In Maplewood, average sale prices have risen roughly 22% since the end of 2025, and with demand nearly double the available supply, the entry point continues to move further away. Slade's team provides resources on navigating competitive offers, appraisal waiver programs, and market-specific guidance on their buyer resources page.
