Cooperative

Instead of owning your unit, you own shares in a corporation that owns the whole building. The shares give you the right to live in a specific unit. Common in older cities, especially New York.

Part 1 of 4

Why a seller cares

A co-op sale is a sale of shares and a lease, and the board has to approve the buyer. It adds an interview, a financial review and weeks to the timeline, and a board can decline without giving a reason.

Part 2 of 4

A simple example

Your co-op buyer submits a board package with tax returns and references. The board interviews them in week five and approves in week six.

In a co-op, the building chooses the buyer too.

What people get wrong

That a co-op sells like a condo. Ownership, financing and approval all differ, and the board is the biggest difference.
