Investment Insights

Based on property information with market context.

This grand, sun-filled mansion is located on a prime park block on the Upper West Side. The 25-foot wide building features a French Renaissance style facade in excellent condition. The interior walls have been mostly removed, highlighting the incredible proportions of the original mansion. With six above-grade floors and ceilings up to 14 feet tall, this townhome is suitable for entertaining or living. The parlor floor is large enough to accommodate a grand living room, dining room, and spacious kitchen all on one floor. The 1,075 square foot roof deck features panoramic views in all directions, including open sky, the New York Historical Society, the San Remo, and a side view of Central Park. Originally built in 1898 and designed by the architecture firm Cleverdon & Putzel, this townhome requires renovation. The townhome was previously purchased by a prominent family with a renowned art collection for use as a private gallery. The spacious townhome could also serve as a home for a school, foundation, or institution. It is located near Central Park and one block from the Museum of Natural History, in the heart of Upper West Side dining, cafes, and shopping. Fully DOB approved plans are available by Zivkovic Connolly Architects.

Financial Insights

Estimated NOI and Cap Rate

NOI = area × lease_rate × (100 − vacancy) / 100 × (1 − expense_ratio). Net Operating Income — what the owner takes home each year before mortgage payments and income tax. Effective rent (asking rent minus vacancy losses) minus operating costs (taxes, insurance, maintenance, management).
NOI / Yr
$384,846
Cap rate = NOI / list price × 100. Capitalization rate — annual return on a fully cash purchase, before financing. NOI divided by price. Higher means more income per dollar invested, but usually also more risk or older condition. 5–8% is typical for stabilized commercial property; double digits often signal distressed deals.
Cap Rate
3.58%
Suggested Prices Based on Cap Rates Cap rates vary significantly by property type, market, and asset quality. Typical U.S. stable-market ranges: Multifamily — 4.5% to 6.5% (Class A in primary markets often sub-5%; Class C in secondary markets 6%+) Industrial / Logistics — 5.0% to 7.0% (compressed heavily in recent years due to e-commerce demand) Office — 6.5% to 9%+ (wide spread post-2020; CBD Class A vs. suburban Class B varies dramatically) Retail — 5.5% to 8.5% (grocery-anchored on the low end, unanchored strip centers higher) Hospitality / Hotels — 7.5% to 10%+ (higher due to operational risk) Self-Storage — 5.5% to 7.5% Medical Office — 6.0% to 7.5% Net Lease (single tenant, credit) — 5.0% to 7.0% depending on tenant credit and lease term Rules of thumb: Primary markets (NYC, SF, LA, Boston, DC) trade at lower cap rates than secondary/tertiary markets, often by 100–200 bps (bps, aka basis points; 1 bp = 0.01%). Class A assets trade ~50–150 bps tighter than Class B, and Class B tighter than Class C. Cap rates move inversely with price — a lower cap rate means a higher price for the same NOI. Spread to the 10-year Treasury is a common benchmark; historically 200–400 bps over the 10-year.
