Seasonal averages from the last 24 months of Mountainside, NJ sales. Individual results vary with price, condition, and how the broader market moves. A local agent can pinpoint the right timing for your home.
What These Numbers Mean for Mountainside Buyers and Sellers
Mountainside operates as a low-supply, high-demand market, and the numbers behind the Housing Market Trends module above make that clear. With only 16 active listings against 21 pending sales and 2.2 months of supply, buyers face genuine scarcity in zip code 07092. The clearest signal of seller leverage is that 72.8% of homes closed above their asking price, and the average sale-to-list ratio sits at 106.24%. When roughly three of every four homes clear above list, a buyer submitting at or below asking is likely to lose to competing offers.
That said, the picture is more nuanced than a straight seller's market. Median days on market registered 18, reflecting a +2 days change in market time, and 14.5% of listings recorded a price reduction. Meanwhile median sale price moved -14.2% year over year to $1,004,496, or about $505.6 per square foot. For buyers, that combination means the properties priced correctly move fast (about 23.6% sell within two weeks), while overpriced listings sit and become negotiable.
For sellers, the data argues for disciplined pricing rather than aspirational pricing. Homes anchored to recent comparable sales tend to attract the competing bids that push final prices above list, whereas a stretch asking price often triggers the reductions showing up in the price-drop share. With 463 licensed agents active locally, the difference between an agent who prices to the current data and one who does not is measurable in both days on market and net proceeds.

What to Look for in a Mountainside Realtor
Choosing an agent in Mountainside should rest on verified performance rather than name recognition or advertising volume. Transaction history, review depth, and pricing accuracy tell you more about likely results than a familiar face on a sign. Among the 463 licensed agents working zip code 07092, EffectiveAgents has ranked 42 based on measured outcomes. Patricia Emma at Keller Williams Realty leads that group with 284 career transactions and $168.6M in all-time sales volume. That experience matters in a market where 72.8% of homes close above list and the average sale-to-list ratio reaches 106.24%, because negotiating a competitive offer or fielding multiple bids requires an agent who has done it repeatedly. In a compact borough where inventory holds near 16 listings, familiarity with how homes move across the entire 07092 area is a practical advantage for both pricing and offer strategy. Emma's 29 reviews reinforce a pattern seen among top-ranked agents: consistent client feedback tracks closely with consistent transaction results.
How We Rank Mountainside Real Estate Agents
Our rankings are built from verified MLS transaction data, not advertising spend. For every agent we analyze more than fifteen performance signals, including sales volume in your city and zip code, recent and all-time transactions, days on market, negotiation results (how far above or below list price an agent's clients actually close), price-point fit, and verified reviews. The agents shown first are those whose verified results put them at the top of the Mountainside market today.
Agents cannot pay for placement in these rankings. The underlying data refreshes as new closed transactions are reported, so rankings shift with real market performance. Learn how we rank agents.

Mountainside Real Estate Agent FAQs
Who is the best real estate agent in Mountainside, NJ?
Patricia Emma at Keller Williams Realty ranks as the top EffectiveAgents-verified agent in Mountainside, NJ, with 284 career transactions, 29 client reviews, and $168.6M in all-time sales volume. EffectiveAgents ranks agents using measured outcomes such as transaction history, sale-to-list performance, and review consistency rather than advertising. Of the 463 licensed agents serving the area, 42 meet the ranking criteria. Comparing several ranked agents against your specific price range and timeline is the recommended way to identify the right fit.
How were these Mountainside real estate agents ranked?
Rankings are built from verified MLS transaction data. We analyze more than fifteen performance signals for every agent, including sales volume in your city and zip code, recent and all-time transactions, days on market, negotiation results, price-point fit, and verified reviews. Agents cannot pay for placement.
How many real estate agents are in Mountainside?
Our data covers 463 real estate agents serving the Mountainside area. The count represents agents with transaction activity recorded in our Mountainside market data, not simply everyone holding a license.
What does the median sale price in Mountainside mean for sellers?
Mountainside's median sale price is $1,004,496 as of July 2026. Half of recent sales closed above that figure and half below. It is a useful baseline for understanding the market, but an experienced local agent will price your home against comparable recent sales in your neighborhood, not the citywide median.
How long does it take to sell a house in Mountainside?
In Mountainside, the median home sells in about 18, and current data shows a +2 days change in market time compared with last year. Roughly 23.6% of homes go off the market within two weeks, so well-priced listings can move quickly. Actual timelines depend on pricing accuracy, condition, and season. Because 14.5% of listings eventually reduce their price, homes anchored to recent comparable sales in zip code 07092 tend to sell faster and closer to their original list price.
Does it cost anything to use EffectiveAgents?
No. EffectiveAgents is free for home buyers and sellers, with no obligation to work with any agent we match you with.
Do agents pay to be ranked or featured?
No. Agents cannot pay for placement anywhere in these rankings. Positions are earned from verified transaction performance only.
What commission do Mountainside realtors charge?
Commissions are negotiable and vary by agent, service level, and transaction. There is no set rate, and recent industry changes have made commission structures more flexible than ever. Discuss the structure directly with your agent before signing a listing or buyer agreement.
Should I use a local Mountainside agent or a national brand?
The individual agent matters more than the brand on the sign. Offices within the same national franchise vary widely in performance, and the agent you hire, not the logo, prices your home, negotiates your contract, and manages your closing. A strong local agent brings firsthand knowledge of Mountainside neighborhoods, pricing patterns, and buyer activity. Compare agents on verified local results such as recent sales, days on market, and negotiation outcomes rather than name recognition.
What questions should I ask a Mountainside realtor before hiring them?
Ask how many homes they have closed in Mountainside in the past year, what their average sale-to-list ratio is, and how much of their business is in your neighborhood and price range. Ask how they will market your home or find you listings, and how often they will communicate. Strong agents answer with specifics. Verified transaction data is the fastest way to confirm what you hear.
