This three-bedroom, three-bathroom split-level offers views of the open bay and the Robert Moses Causeway, says listing agent Jerilyn Kaich of Ramsay Realtors. “Pretty much every room, including the bedrooms, has a water view,” she says. That includes the upper-level great room, which features a fireplace, vaulted ceilings with skylights and sliding glass doors that open to a balcony. Beyond the foyer on the main level of the 1960 house is an eat-in kitchen with stainless steel appliances and sliders, and a formal dining room. On the next level is the master bedroom, with French doors opening to a deck in the backyard, and two additional bedrooms and two full baths. All three bathrooms in the house have been updated within the past five years, Kaich says. The 75-by-150-foot property, with taxes of $16,219, includes 75 feet of new bulkhead and a one-car garage.

This bayfront high-ranch, with five bedrooms and four full bathrooms, includes new bulkhead, says listing agent Tina Canaris of Douglas Elliman Real Estate. The 1964 stucco house, overlooking Merrick Bay, has had expansions on both the upper and lower levels, she adds. “Besides the extra living space, it’s not the typical high-ranch,” Canaris says. The den on the lower level has a full-wall, brick fireplace and French doors that open to the backyard. A bedroom on the lower level also has French doors offering water views. The main level, with hardwood floors, includes the living room, extended eat-in kitchen and formal dining room. The master bedroom, also extended, has two full bathrooms, Canaris says. The 0.15-acre property, with taxes of $30,701, has an attached two-car garage. Tina Canaris, Douglas Elliman Real Estate, 516-695-8462
