Realtors report a surge of New Yorkers looking to buy homes in Connecticut, a trend dubbed the “Mamdani effect” after the election of Zohran Mamdani as New York City mayor. Buyers are expanding searches, especially in Fairfield, New Haven and Litchfield counties, citing concerns over potential tax and cost increases from Mamdani’s policies. Agents say the demand is strong, driving up competition for available homes and creating a tight housing market in some towns.
