Buying and selling

Refund window

The period during which a buyer can return a listing and get their money back.

The standard window matches the escrow hold, so an ordinary refund is a release of held funds rather than a clawback from a maker who has already been paid.

The window is stated on every listing before purchase, and it is the thing to check when a listing offers no sandbox.

Why it matters

Either a sandbox or a refund window should exist before you pay. Where neither does, you are being asked to carry all of the risk.

The mistake everyone makes

Discovering a runaway metered bill at month end, outside the window. Check spend on day three.
