MANHATTAN NEIGHBORHOOD GUIDE
Flatiron Apartments for Sale
Loft conversions, full-service condominiums and new development around Madison Square Park.
By Anthony Guerriero, Manhattan Miami Real Estate | Updated August 2026
Flatiron rewards buyers who read the blocks carefully. Ladies' Mile loft conversions west of Fifth Avenue, full-service towers near Madison Square Park and quieter residential streets toward Gramercy offer different light, scale and resale audiences. I would not collapse this market into NoMad simply because both face the park.
Flatiron Real Estate Map
Flatiron runs from East 14th Street to East 23rd Street, between Sixth Avenue and Park Avenue South, with Madison Square Park and the Flatiron Building anchoring the neighborhood’s northern edge at 23rd.

Flatiron at a Glance
Flatiron Market Overview
Prewar stock dominates. Unlike NoMad (north of 23rd) which is predominantly new-development tower inventory, Flatiron’s fabric is older, prewar commercial lofts converted to residential, co-op buildings from the early 20th century, and a handful of new-construction insertions. This creates a mixed co-op/condo market with more entry points than NoMad but fewer trophy-tier towers.
New development scarcity. Available new-development inventory in editorial Flatiron concentrates along the 22nd Street corridor (Madison Square Park Tower, One Madison, 5 East 22nd, 21 East 22nd). Once these buildings sell out, resale is the primary transaction path. Trophy product on the Madison Square Park north edge (10 Madison Square West, 212 Fifth Avenue, The Whitman) sits just north of 23rd in NoMad and is occasionally cross-marketed under either label.
Park proximity premium. Madison Square Park is the neighborhood’s northern anchor at 23rd. Buildings within one or two blocks of the park trade at meaningful premiums to comparable units further south. Floor height and exposure direction (north vs south, park view vs avenue view) are the primary differentiators within the same building.
Co-op vs condo mix. Flatiron is roughly 40% co-op, 60% condo, a more balanced mix than the condo-dominant markets to the north and west. Co-ops provide lower per-foot entry pricing but carry board approval, sublet restrictions, and financing requirements that international and pied-à-terre buyers may find prohibitive.
Price Ranges by Property Type
| Property Type | Typical Price Range |
|---|---|
| Studios & 1-Bedrooms (co-op) | $800K-$2M |
| 1-Bedroom (condo) | $1.2M-$2.5M |
| 2-Bedroom (condo) | $2.5M-$5M |
| 3-Bedroom | $4M-$10M |
| Penthouse / Full-Floor | $10M-$50M+ |
Pricing varies by building (prewar loft vs new-development tower), floor height, park exposure, and renovation state. Buildings within one or two blocks of Madison Square Park trade at material premiums over equivalent units further south within the neighborhood.
Notable Buildings

Buildings frequently grouped with Flatiron in marketing, 10 Madison Square West (24th), 212 Fifth Avenue (26th), and The Whitman (21 E 26th), sit just north of 23rd along Madison Square Park’s north edge and are editorially NoMad. They are flagged here for buyers comparing the broader Madison Square Park corridor.
Living in Flatiron
Madison Square Park anchors the neighborhood’s northern edge. The park sits just north of 23rd Street, framing the Flatiron Building at the apex of the neighborhood and serving as the primary green space for residents. Buildings in the upper Flatiron blocks (20s) trade at premiums tied to walking distance from the park.
Design and food culture. Flatiron hosts Eataly, a dense restaurant tier along Park Avenue South and Broadway, and a retail spine combining fashion, beauty, and home design. The neighborhood’s daytime energy is driven by tech and creative office tenants (the original Silicon Alley), giving it a live-work density that persists after hours.
Prewar architecture. The stock is predominantly lower-rise prewar lofts and landmark commercial buildings converted to residential, with boutique new construction threaded between them along the 22nd Street corridor. This mixed fabric is part of Flatiron’s appeal, architectural variety within a compact footprint.
