Prime Opportunity in Carnegie Hill

Welcome to Unit 1C at 108 East 91st Street, a rare flexible-use opportunity nestled in a stunning Neo-Renaissance boutique co-op just off Park Avenue. Spanning approximately 600 square feet, this ground-floor unit is currently configured as an office space but can be converted into a charming residential residence, offering endless potential for end-users or investors.

Featuring 9-foot ceilings, the space feels open and airy, enhancing its flexibility whether used for commercial or residential purposes.

The building exudes timeless elegance with a part-time doorman on duty from 8 AM to midnight, seven days a week, and the convenience of a live-in resident manager. Additional amenities include a laundry room for residents and a pet-friendly policy, all within a well-maintained, prewar setting that blends historic charm with modern service.

Perfectly situated just two blocks from Central Park and around the corner from the iconic 92nd Street Y, the location offers immediate access to the very best of the Upper East Side-world-class museums, cultural institutions, restaurants, and shops. Commuting is a breeze with the 86th Street 4/5/6 trains and the Second Avenue Q line.

The margin for this adjustable rate mortgage may vary with your unique credit history, and terms of your loan.

** Mortgage Rates are subject to change, loan amount and product restrictions and may not be available for your specific transaction at commitment or closing. Rates, and the margin for adjustable rate mortgages [if applicable], are subject to change without prior notice.

The rates and Annual Percentage Rate (APR) cited above may be only samples for the purpose of calculating payments and are based upon the following assumptions: minimum credit score of 740, 20% down payment (e.g. $20,000 down on a $100,000 purchase price), $1,950 in finance charges, and 30 days prepaid interest, 1 point, 30 day rate lock. The rates and APR will vary depending upon your unique credit history and the terms of your loan, e.g. the actual down payment percentages, points and fees for your transaction. Property taxes and homeowner's insurance are estimates and subject to change.  The Total Monthly Payment does not include the estimated HOA/Common Charge payment.
