Property Description

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
  • On-site laundry
  • Pet-friendly policies (subject to board approval)
  • Private storage
Located in the heart of Hell's Kitchen, the building is surrounded by dining, nightlife, and convenient access to Midtown Manhattan. The apartment's courtyard-facing orientation provides a rare sense of quiet and separation from the surrounding energy giving you the best of both worlds.

This is an HDFC co-op with a 165% AMI income cap.

  • 1 Person: $187,110
  • 2 People: $213,840
  • 3 People: $240,570
This apartment is built for someone who values design over excess, flexibility over fixed layouts, and low monthly costs over wasted space. If that mindset aligns with how you live, there are very few opportunities like this currently on the market.
