Maplewood, NJ's housing market is showing stronger momentum than conventional metrics indicate, according to a new measurement tool developed by Mark Slade of Mark Slade Homes. The "hyper market index" compares the number of properties under contract against the combined total of active listings, properties in attorney review, and coming-soon inventory, providing a real-time snapshot rather than the backward-looking absorption rate.
As of late June 2026, the index readings across six tracked towns show Maplewood at 1.9—nearly twice as many properties under contract as actively available. South Orange follows at 1.7, while West Orange (1.1) and Union (1.3) also exceed the hyper threshold of 1.0. Livingston, at 0.8, is the only town where supply outpaces buyer commitment, according to Slade's data.
Slade pulls his data directly from the Garden State MLS, the primary listing system for agents in the corridor. He notes that Zillow aggregates from multiple sources, including private listings not on Garden State MLS, leading to discrepancies. 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 local market.
Percent-over-asking figures reinforce the index readings. Maplewood's average sale price is $1,323,000—up roughly $220,000 from year-end 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 has the second-highest average price at approximately $1,350,000 but the weakest percent-over-asking result at 2.9%.
Slade emphasizes that waiting is costly in this market. In Maplewood, where demand runs at nearly twice the available supply, the cost of deferring a purchase compounds quickly. "Buyers who sit out are not preserving optionality—they are watching the entry point move further away," he said.
