1. 825 Fifth Avenue
One of the Gold Coast’s best co-ops—so why such a dizzying swing in prices? The eighteenth-floor monster has 64 feet fronting Central Park; the small two-bedroom is in the back.

Apt. 18ABC, 18D: $14 million.

Apt. 6DE: $1.675 million.
Two-bedroom, two-bath. Maintenance: $3,131. (Barbara Cardozo, Elliman.)

2. 29 East 64th Street
Maintenance is a bear at this white-glove co-op, so you won’t need the servant’s room with bath in 6C. Then face the un–New Yorkish dilemma of dealing with an extra bed and bath.

Apt. 9A:
$3.35 million. Three-bedroom, two-bath; 2,250 square feet. Maintenance: $3,657. (Lauren Muss, Corcoran.)
Apt. 6C: $2.995 million.

Apt. 10D: $5.9 million.
Two-bedroom, 2 1/2-bath; 2,800 square feet. Maintenance: $5,028. (Caroline Guthrie, Edward Lee Cave.) Ignore the excessively floral décor—this grande dame co-op has north-facing floor-to-ceiling windows, as well as views to the east and west.

4. 601–603 Park Avenue: $30 million.
Five-story townhouse. (Brian J. Manning, Brown Harris Stevens.) Think of it as a megayacht moored on Park Avenue—one with 100 feet of façade.

5. 32 East 64th Street: $6.995 million.
Four-bedroom, 4 1/2 bath. Maintenance: $5,720. (Michele Kleier, Gumley Haft Kleier.) Footing the bill for the additional 2% flip tax helps buy you into a premier landmarked building and impeccable apartment with all the trimmings, including fireplace, tons of closets, park views, and solarium.

6. 118 East 64th Street: $4.9 million.
Four-story townhouse; 3,200 square feet. (Suzanne Sealy, Elliman.) This 12 1/2-foot-wide jewel-box townhouse is snug but still covetable—it’s James Ware’s city version of his upstate Tyrolean folly, the Mohonk Mountain House.

7. 121 East 64th Street: $12.95 million.
Five-story townhouse; 7,000 square feet. (Cindy Bernat, Corcoran.) This landmarked twenties property has ten rooms, two outdoor spaces, and pristine old-world detailing. If it feels too collegiate-Gothic, just rip out the heavy wood paneling and bedroom chandelier.

8. 129 East 64th Street: $14 million.
Seven-story townhouse; 7,000 square feet. (Suzanne Sealy, Elliman.) Has Irish pine floors, four working fireplaces, and a somehow ungarish elevator padded with yellow leather. But what would former owner Otto Preminger have made of the Panic Room security?

9. 136 East 64th Street
Apt. 9F: $1.7 million.
Two-bedroom, two-bath; 1,350 square feet. Maintenance: $2,143. (Leslie Crossley, Brown Harris Stevens.) With nine-foot ceilings and a stately living room, this small co-op apartment acts big—even without the mirrors and animal-print carpeting.

10. 176 East 64th Street: $15.9 million.
Five-story townhouse; 6,000 square feet. (Carrie Chiang, Corcoran.) You’ll have eleven rooms, including a basement with staff living quarters and a family room with a twenty-foot cathedral ceiling. Feeling boxed in? You can always escape to the 600-square-foot garden for a fountain-side retreat.

11. 188 East 64th Street: The Royale.

12. 301 East 64th Street: Regency East.
With a Gourmet Garage downstairs in this postwar co-op building, there’s no need to schedule your Sundays around FreshDirect—but also no room left for a gym, storage, or common spaces.

13. 340 East 64th Street: The St. Tropez.
