Maplewood's housing market is running hotter than the headlines suggest, according to a local real estate team that tracks weekly data using a proprietary metric they call a 'hyper market index.' The standard measure most agents use, absorption rate, looks at closed sales divided by active inventory over the past six months. But in a market moving as fast as Maplewood, that number is already stale by the time it lands. For nearly 17 years, Mark Slade, who leads Mark Slade Homes, with his partner MaryCeu Nunes, has been tracking commuter markets across Essex and Union County on a weekly basis using a different measure entirely.
The hyper market 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. The logic is straightforward: under-contracts reflect recent decisions buyers have made, with the vast majority of deals made in the past one and a half to two and a half months. In contrast, absorption rate averages performance over six months, potentially masking current trends. As of late June 2026, Maplewood's index reading stands at 1.9, meaning there are nearly twice as many properties under contract as there are actively available. Slade views any reading above 1.0 as a hyper market. Other towns in the area show varying readings: Livingston at 0.8, West Orange at 1.1, Union at 1.3, and South Orange at 1.7.
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, meaning the two datasets measure different things. 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. 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 where it ended 2025 – with properties selling at 16.1% over asking on average. South Orange is at 15.5% over asking, with an average price of $1,221,000. Both towns ended last year below their current hyper market readings.
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. For buyers still waiting, the case for deferring a purchase is harder to make. In Maplewood, where the average sale price has risen roughly 22% since the end of last year and properties consistently close well above asking, the cost of waiting compounds quickly. Slade's position is direct: in a market where demand runs at nearly twice the available supply, buyers who sit out are not preserving optionality – they are watching the entry point move further away.
