A hyper market index developed by a local real estate team is showing that Maplewood, NJ's housing market has significantly more momentum than conventional data suggests. Mark Slade, who leads Mark Slade Homes with his partner MaryCeu Nunes, created the index to read market conditions in real time rather than retrospectively. The index compares the number of properties 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.
As of late June 2026, the index readings across six tracked towns show Maplewood at 1.9, meaning there are nearly twice as many properties under contract as there are actively available. South Orange follows at 1.7, West Orange at 1.1, Union at 1.3, and Livingston at 0.8. Slade views any reading above 1.0 as a hyper market, indicating a significant imbalance favoring sellers. In contrast, the standard absorption rate, which looks at closed sales divided by active inventory over the past six months, can be stale by the time it lands, especially at the turn of the year when it averages performance from months with different conditions.
Slade pulls his data directly from the Garden State MLS, the primary listing system used by agents in the corridor. Zillow aggregates from multiple sources, including private and exclusive listings that never appear on the Garden State MLS, so the two datasets are not measuring the same thing. For buyers and sellers in Maplewood and South Orange, the practical implication is that Zillow's market reads can be materially off from what is actually happening in the Garden State MLS-driven market they are transacting in.
The percent-over-asking figures reinforce the hyper market readings. As of the week ending June 21, Maplewood's average sale price is $1,323,000, up roughly $220,000 from the end of 2025, with properties selling at 16.1% over asking on average. South Orange is at 15.5% over asking, up from 10.5% at year-end 2025, with an average price of $1,221,000. Livingston, with the second-highest average price at about $1,350,000, has the weakest percent-over-asking result at 2.9% and a hyper market ratio of 0.8, indicating supply is outpacing buyer commitment.
For buyers waiting to enter the market, the cost of deferring a purchase compounds quickly. 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, buyers who sit out are watching the entry point move further away. Slade's team offers resources for navigating competitive situations, including their buyer resources page, which covers appraisal waiver programs and market-specific guidance.
