What These Numbers Mean for Mamaroneck Buyers and Sellers
The Housing Market Trends module above outlines a Mamaroneck market where competitive pressure and cautionary signals sit side by side. Inventory measures just 20 active listings against 1.3 months of supply, a level that structurally favors sellers, and 73.3% of homes sold above their asking price while the sale-to-list ratio holds at 107.54%. With 29 pending sales against 17 new listings each month, demand continues to absorb supply faster than it is replaced. For a buyer, that combination means well-priced homes require competitive, often above-list offers, and hesitation on the strongest listings is costly given that 37.9% leave the market within two weeks. At the same time, 45.0% of listings recorded a price cut, and the median sale price moved -24.1% year over year, which signals that overpriced or mispositioned homes are being reset rather than bid up. That split is where negotiating leverage concentrates: aggressive on move-in-ready inventory, patient on stale listings that have already dropped. Median time on market sits at 14 days, reflecting a -10 days change in market time, so pricing accuracy at listing has become more decisive than a year ago. For a seller, the takeaway is to price to the current comps rather than last year's peak, since the 45.0% price-drop share shows the penalty for anchoring too high, while correctly priced homes still clear above list. Across the area, 1,028 licensed agents compete for this business, and separating the ones who consistently price and negotiate well from the rest is where an informed choice matters most.

What to Look for in a Mamaroneck Realtor
Choosing an agent on name recognition alone overlooks what actually determines outcomes: transaction volume, negotiation results, and consistency across cycles. In Mamaroneck, EffectiveAgents has ranked 34 agents out of 1,028 licensed locally, using measured performance rather than advertising spend. The top-ranked agent, Cathy DeVore at Houlihan Lawrence, has closed 521 transactions with $768.1M in all-time sales volume, a track record that matters in a market where 73.3% of homes sell above list and pricing precision separates strong outcomes from price cuts. Negotiation skill is concrete here: in Rye Neck and across zip code 10543, an agent who reads the 107.54% sale-to-list environment correctly can guide a buyer's offer strategy or protect a seller from the 45.0% price-drop trap. When reviewing agents, look at review patterns over time rather than a single testimonial. Cathy DeVore's 28 reviews, read alongside verified transaction data, offer a fuller picture of how an agent performs across varied listings and negotiations than a headline count ever could.
How We Rank Mamaroneck 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 Mamaroneck 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.

Mamaroneck Real Estate Agent FAQs
Who is the best real estate agent in Mamaroneck, NY?
Cathy DeVore at Houlihan Lawrence is the top-ranked agent in Mamaroneck, NY, according to EffectiveAgents, with 521 transactions and $768.1M in all-time sales volume. EffectiveAgents ranks agents using verified transaction history, sales performance, and client reviews rather than advertising, analyzing 155 annual transactions across 1,028 licensed local agents to identify the 34 who consistently perform. The right agent for you depends on your neighborhood, price point, and whether you are buying or selling, so compare ranked candidates on results that match your situation.
How were these Mamaroneck 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 Mamaroneck?
Our data covers 1,028 real estate agents serving the Mamaroneck area. The count represents agents with transaction activity recorded in our Mamaroneck market data, not simply everyone holding a license.
What does the median sale price in Mamaroneck mean for sellers?
Mamaroneck's median sale price is $835,000 as of May 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 Mamaroneck?
Homes in Mamaroneck currently take a median of 14 days to sell, reflecting a -10 days change from last year. With 37.9% of homes leaving the market within two weeks, well-priced and well-presented listings move quickly, while 45.0% of listings that record a price cut tend to sit longer. Your actual timeline depends on pricing accuracy at listing, condition, location within zip code 10543, and seasonality. Pricing to current comps rather than last year's peak is the single largest factor in a fast sale.
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 Mamaroneck 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 Mamaroneck 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 Mamaroneck 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 Mamaroneck realtor before hiring them?
Ask how many homes they have closed in Mamaroneck 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.
