lock period

Definition

The guaranteed timeframe during which your mortgage interest rate won't change, typically 30-60 days. It's a race between closing and your lock expiring, with your financial future hanging in the balance.

Example Usage

Our lock period expires in two days and the seller just asked for a week extension—time to panic.

Origin

Mortgage industry practice standardized in the 1980s during high interest rate volatility

Fun Fact

You can pay extra to extend a lock period, proving that even your interest rate has an expiration date and everything costs more than expected.

duplex

A single building cleverly divided into two separate dwelling units, allowing property owners to live in one half while collecting rent from neighbors who share their walls. It's the real estate equivalent of having your cake and eating it too, assuming you don't mind hearing your tenant's TV through the drywall. In postal circles, it's also a fancy stamp cancellation, but nobody cares about that definition anymore.
