Overview

Welcome to 6541 South Kostner Avenue, a beautifully maintained brick Cape Cod offering four bedrooms, two full bathrooms, and a fully finished basement. The main level welcomes you with beautiful hardwood floors that flow seamlessly through a bright living room and into a dedicated dining area. Cooking is effortless in the well appointed kitchen, which features stainless steel appliances alongside generous cabinet space. Two additional bedrooms are located on the upper level, providing comfortable and private accommodations. The finished basement significantly expands the usable footprint of the property.

Additional essential updates include a 2021 furnace, a 2019 garage door, and an air conditioning system from approximately 2018. The washer and dryer were added in 2018, rounding out a comprehensive list of improvements that also includes a 2013 water heater and a 2011 roof
