Mamaroneck Real Estate Market Update: August 2026
Single-family homes, condominiums, co-ops and multifamily properties
One of the pleasures of spending time in Mamaroneck is being able to walk around Mamaroneck Harbor and then head up Mamaroneck Avenue to Sal’s Pizza, just up the street. That short walk connects two familiar parts of the community: the waterfront and an active downtown filled with local businesses.
That personal experience is not a housing statistic, but it helps explain why local real estate cannot be understood only through numbers. Mamaroneck offers waterfront activity, neighborhood streets, local restaurants, shopping and transportation within a compact area. The August 2026 market reports add the data needed to understand how buyers and sellers were responding across different property types.

The most striking result was the shortage of single-family homes. Inventory fell 59% from one year earlier, leaving less than one month of supply. Condos and co-ops also recorded relatively small numbers of sales, while only two multifamily properties closed. Those sample sizes make it important to examine each segment separately and avoid applying one monthly median to every property.

Single-Family Homes: Less Than One Month of Supply
The single-family report showed an exceptionally limited supply of available homes. Inventory fell to 16 homes, down 59% from August 2025. That represented only 0.93 months of supply, a year-over-year decline of 60.4%.
- 35 sales, up 20.7% year over year
- $2,326,018 median sale price, up 12.8%
- 17 median days on market, down 10.5%
- $786 median sale price per square foot, up 7.5%
- 97% sold within 90 days
- 94% sold for more than 95% of list price
Less than one month of supply indicates that buyers had very few choices relative to the recent pace of sales. The combination of higher sales, a shorter median marketing time and sharply lower inventory is consistent with a competitive single-family segment during August.
The $2,326,018 median should still be interpreted carefully. The particular mix of homes sold during a month—including their size, location, condition and price range—can move the median. It does not mean every home in the Mamaroneck School District gained 12.8% in value.
Mamaroneck Condos: More Supply and Longer Market Time
Five condominiums sold in August, up 25% from August 2025. The median sale price was $645,000, down 13.7%, while the median price per square foot increased 1% to $633.
- 8 units in inventory, up 33.3%
- 2.46 months of supply, up 53.8%
- 56 median days on market, up 143.5%
- 80% sold within 90 days
- 100% sold for more than 95% of list price
The condo figures suggest that buyers had somewhat more selection and properties took longer to sell. However, only five transactions closed. A small change in the types of units sold can substantially affect the median price and market time.
Condo buyers and sellers should compare units by location, building, size, condition, parking, amenities, common charges and taxes. Those property-specific factors are often more useful than a single school-district median.
Mamaroneck Co-ops: Lower Inventory and Faster Sales
The co-op market recorded 6 sales, down 50% year over year. The median sale price was $309,500, down 1.3%, while the median price per square foot rose 4.2% to $362.
- 13 units in inventory, down 31.6%
- 2.05 months of supply, down 32.5%
- 28 median days on market, down 60%
- 83% sold within 90 days
- 100% sold for more than 95% of list price
Co-op inventory tightened and the median time on market dropped considerably, but the six-sale sample remains small. The nearly unchanged median price and modest increase in price per square foot provide additional context, yet individual building comparisons remain essential.
Co-op buyers need to evaluate monthly maintenance, included expenses, building finances, financing policies and board requirements. Buyers should review the complete financial and legal package with their attorney and lender. Sellers should gather building documents early to reduce preventable delays.

Mamaroneck Multifamily Homes: Two Sales Require Caution
Only two multifamily properties sold in August, unchanged from August 2025. The reported median sale price was $1,082,500, down 13.4% year over year.
- 14 median days on market, up 40%
- 7 properties in inventory, up 133.3%
- 9.33 months of supply, up 185.2%
- 100% sold within 90 days
- 100% sold for more than 95% of list price
Although the inventory and months-of-supply percentages increased sharply, they started from very small numbers. With just two sales and seven available properties, one or two listings can create a large percentage change. These results should not be treated as a broad valuation trend.
Multifamily properties require property-specific analysis. Unit count, rents, expenses, leases, legal use, taxes, condition and anticipated capital improvements can matter as much as recent sale prices.
What the August Market Means for Mamaroneck Buyers
Buyers should prepare according to the property type they are considering. The 0.93-month supply of single-family homes points to a highly competitive segment where financing, timing and a clear offer strategy matter. Condo buyers had slightly more supply, while the co-op market remained relatively tight.
- Obtain a current mortgage pre-approval or prepare proof of funds.
- Understand the complete monthly cost, including taxes, insurance and applicable common charges or maintenance.
- Review recent comparable sales before determining an offer strategy.
- Study building finances and rules when purchasing a condo or co-op.
- Evaluate leases, income, expenses and legal use when considering a multifamily property.
Competition should never replace careful decision-making. A sound purchase balances timely action with appropriate inspections, financial review and advice from qualified real estate, legal and lending professionals.
What the August Market Means for Mamaroneck Sellers
Single-family sellers faced very little competing inventory in August. That can create an opportunity, but it does not guarantee a particular sale price. Accurate pricing, preparation, photography and marketing remain important because buyers compare every property with the alternatives available at that moment.
Condo and co-op sellers should prepare building documents early and understand how monthly charges affect buyers’ total cost. Multifamily owners need an analysis that includes leases, operating information, property configuration and investment fundamentals.
Beginning the planning process before you are ready to list provides time to evaluate repairs, property presentation, required documents and a realistic pricing strategy without unnecessary pressure.
Thinking About Buying or Selling in Mamaroneck?
School-district statistics provide useful context, but your decision should be based on the segment that actually matches your home or search. I would be glad to prepare a focused analysis for a single-family home, condominium, co-op or multifamily property in the Mamaroneck area.
