An exceptional opportunity for both end users and investors, the apartment is currently leased to an outstanding tenant paying **$20,000 per month**. The tenant has an impeccable payment history, has always paid rent on time, and has been a pleasure to work with. They are happy either to remain in the apartment, providing immediate rental income, or to vacate with an early lease termination should the purchaser wish to occupy the residence. This unique flexibility makes the property an outstanding investment opportunity, currently generating approximately a **5% yield**, while also allowing for future owner occupancy.

Opportunities like this are rare in this highly desirable Flatiron boutique condominium.

This expansive 2,260 SF loft offers two bedrooms plus a home office (easily a third bedroom) and three full baths, all framed by 10-foot ceilings, abundant southern light, and fresh, top-to-bottom renovations.

A key-locked elevator opens directly into an impressive gallery that flows into a vast living and dining area with four oversized windows overlooking 20th Street. The gas fireplace with stone surround sets the tone for elegant entertaining, while the dining area easily seats eight. The home is equipped with electric shades and a Control4 smart home system that manages Sonos audio, lighting, and more.

Unique to this residence, the kitchen has been completely opened to the living space and is anchored by a generous center island with seating. Outfitted with sleek Scavolini cabinetry, stone countertops and backsplash by Porcelanosa, and a full suite of high-end appliances-including a Sub-Zero refrigerator, Wolf range and oven, second Miele oven, Miele dishwasher, built-in Miele espresso maker, two wine refrigerators, and a Miele microwave-it is equally suited for everyday living and sophisticated entertaining.

The bedroom wing is arranged for maximum privacy. The king-sized primary suite boasts a custom walk-in closet and a spa-caliber five-piece bath featuring a double vanity, Robern medicine cabinets with built-in outlets, a rainfall shower, heated floors, an air-jet soaking tub with a built-in television, and a separate water closet. The second bedroom is serviced by a full bath with a glass-enclosed shower. A spacious home office (or third bedroom), full-size shelved laundry room, dual-zone central HVAC, wide-plank hardwood floors, and recessed lighting complete this exceptional residence.

**The Building**

Originally constructed in 1906 and fully redeveloped by Extell Development into a luxury condominium, 15 West 20th Street-also known as the Altair-combines the character and scale of a pre-war building with the infrastructure, finishes, and amenities of a modern luxury residence. The beautifully restored facade is a striking example of classic New York architecture, while the renovated lobby reflects the building's elevated design standards. With only 17 residences, Altair offers an intimate boutique living experience. Amenities include a part-time doorman, fully equipped fitness center, landscaped roof deck with grill and shaded seating, and oversized private storage for every residence.

**The Neighborhood**

Situated on a quiet block in the heart of Flatiron, you're moments from Madison Square Park, the iconic Flatiron Building, and renowned dining destinations including Eataly and ABC Kitchen. The neighborhood continues to flourish with sought-after additions such as Pura Vida, the Ritz-Carlton and its celebrated NuBeluz rooftop lounge, the Virgin Hotel, and the exclusive NoMad Members Club featuring Cecconi's restaurant. World-class shopping, cultural institutions, and multiple subway lines are all just moments away, placing the very best of Manhattan at your doorstep.
