646 9th Avenue, Apt 3RN - HDFC Co-op for Sale in Hell's Kitchen, Manhattan High-DesignLow Monthlies 1-Bedroom $549, 000 $395 Monthly Maintenance (Includes Taxes) This Hell's Kitchen HDFC co-op offers a rare opportunity to purchase a thoughtfully designed, low-maintenance apartment in Manhattan with a 165% AMI income cap. Located at 646 9th Avenue, Apartment 3RN has been fully reimagined for modern, flexible living-ideal for buyers who value efficiency, intentional design, and long-term affordability. What Makes This Apartment Unique HDFC co-op with 165% AMI income cap Ultra-low $395/month maintenance (includes taxes) Fully customized multi-functional transformer layout Private basement storage included Located in Hell's Kitchen with access to Midtown Manhattan A Reimagined Approach to One-Bedroom Living This is not a traditional one-bedroom designed around excess square footage or conventional layouts. Instead, the apartment has been engineered as a high-functioning, design-forward space that adapts to how you live throughout the day. At the center of the home is a custom motorized Horigotatsu platform-a true 3-in-1 living system that eliminates the need for separate living, sleeping, and dining areas. It functions as a minimalist lounge, converts into a full bed, and transforms into an elevated dining or workspace at the push of a button. This is not a compromise for space-it is a deliberate solution for modern Manhattan living. The layout supports a seamless daily rhythm: Morning: open, uncluttered lounge Midday: clean, elevated workspace ideal for remote work Evening: comfortable living and sleeping environment Climate control is handled by dual LG Artcool Gallery mini-splits, designed to resemble framed artwork while providing efficient heating and cooling-eliminating the need for traditional wall units. Streamlined Kitchen with High-Performance Appliances The open kitchen continues the theme of intentional design with: Quartz countertops Custom Cabinets Bosch dishwasher LG refrigerator Samsung microwave 2-burner gas range Each element has been selected for performance and efficiency without unnecessary excess. Bathroom as a Private Retreat The windowed bathroom is designed as a functional recovery space. It features: Jacuzzi soaking tub with integrated wall jets Rainfall showerhead Custom sliding wooden barn door for space efficiency An adjustable rod system provides a discreet in-unit drying solution, reinforcing the apartment's focus on intelligent, multi-purpose design. Storage Designed Differently Not only is there plenty of storage through the apartment there is also a private basement storage cage-allowing bulk and seasonal items to be stored on-site and keeping the living space clean and uncluttered. The layout supports a streamlined wardrobe solution near the entry, aligned with a minimalist lifestyle should you require additional hanging space. Financial Profile & Building Stability With maintenance at just $395 per month-among the lowest in Manhattan-this property offers a compelling combination of affordability and design. The building is a financially stable HDFC co-op with no long standing debt and strong reserves. This level of financial health is rare in income-restricted co-op buildings allowing the board to have undertaken hallway renovations and to build a roof deck in recent years. Building Amenities & Location Residents enjoy access to: Landscaped courtyard Furnished roof deck</
