145-147 West 105th Street is a boutique HDFC co-op consisting of two connected prewar brownstone buildings with 20 units total on a prime Upper West Side block. The self managed cooperative maintains exceptionally low monthly fees while making continuous capital improvements without assessments or maintenance increases. Recent upgrades include replacement of all windows and railings, a new roof with solar panels that generate credits to reduce shareholders' electric bills, and included Spectrum cable, HBO, and 1 gig internet service. The building has no underlying debt and maintains significant reserves, with planned lobby and hallway renovations also funded without additional costs to residents.
Apartments feature classic prewar details including high ceilings ranging from 9.5 to 11 feet, decorative mantles with non operational wood burning fireplaces, original hardwood floors, solid wood entryways and doors, intricate moldings, pocket shutters, and glass transoms above door frames. Units typically offer south facing exposures with strong natural light, large closets, and flexible layouts. The cooperative is accommodating with renovations subject to board and DOB approval, and residents in various lines have successfully relocated kitchens, added bathrooms, and installed central air systems. Many available units require full renovation, presenting opportunities for customization.
Building amenities include a shared courtyard with porch swing, gas BBQ, and pizza oven for residents' use, in-unit washer/dryer installation permitted, free bike storage, and additional basement storage available for $25 monthly. The cooperative is pet friendly with a live in superintendent and operates as a walk up building without elevators. A 5% flip tax is paid by sellers. As an HDFC cooperative, income restrictions at 165% of Area Median Income apply, though gifting is allowed, with maximum income limits ranging from approximately $137,940 for a single person to $310,200 for a family of six depending on the current AMI levels.
The location offers easy access to Central Park and Riverside Park, with the 1, B, and C subway lines within a few blocks and multiple bus lines nearby. The neighborhood features abundant dining and shopping options including Whole Foods, H Mart, Silver Moon Bakery, Absolute Bagels, Blue Bottle Coffee, and dozens of restaurants, cafes, and specialty food shops.

For some co-ops, instead of price per square foot, we use an estimate of the number of rooms for each sold apartment to chart price changes over time. This is because many co-op listings do not include square footage information, and this makes it challenging to calculate accurate square-foot averages.
By displaying the price per estimated room count, we are able to provide a more reliable and consistent metric for comparing sales in the building. While we hope that this gives you a clearer sense of price trends in the building, all data should be independently verified. All data provided are only estimates and should not be used to make any purchase or sale decision.
