How Buying Here Works
The product overlap is nearly total: Midtown addresses across from the beach, walkable to Worth Avenue, with large mid-century lines that renovate beautifully. The divergence is structural. The co-op vets buyers and limits financing, the condominium does neither, and the recorded spread between the two is the market's price for that freedom.
Buyers should decide the structure question first. Cash buyers comfortable with boards unlock the co-op's discount, while financed buyers and future landlords generally need the condominium's rules.
The Alternative
The table below puts the pair side by side. Four Hundred South Ocean's premium per foot is the condominium's flexibility priced in, and the co-op's discount survives because its buyer pool is structurally smaller. Neither number is mispriced. They are two correct answers to different ownership questions.

Timing and Leverage
Both buildings run on Midtown's winter calendar, and both trade thin enough that one listing changes the market. The practical edge goes to buyers tracking both doors at once, since the right line in either building answers the same underlying brief. Crossing the street is cheaper than waiting a season.
The Checklist
Before the offer: the governance documents for whichever structure, with maintenance and assessments compared honestly. Renovation rules differ between the two, and the per foot spread belongs against the latest recorded trades. Structure first, line second, price third.
Bottom Line
Three Hundred and Four Hundred South Ocean sell the same Midtown life under different constitutions, and the per foot spread is the price of the condominium's freedom. Buyers who settle the structure question first find the rest of the file settles itself.
The working rule on this block: decide co-op or condominium before touring either lobby, and the right building chooses itself.
