Rate locks: common assumptions to revisit

A rate lock establishes specified pricing for a stated period subject to its terms.

Common assumptions to revisit

A familiar rule of thumb is only a starting point. An extension or a changed application may affect the final cost. In the context of rate locks, ask whether an assumption came from your own documents, an advertisement, a friend’s transaction, or a lender’s review of your file. Those sources do not carry the same weight. Replace uncertain figures with documented estimates and label anything that remains unresolved.

Put the tradeoff in context

An extension or a changed application may affect the final cost. Ask what happens if closing moves beyond the lock expiration. Your primary residence is both a place to live and a continuing financial responsibility. A financing decision should fit the time you expect to own the home, the money left after closing, and the other priorities in your household. An estimate is useful only when you understand what it includes.

Turn the idea into an action

Gather written lock confirmation and closing timeline. Write down the questions that remain and ask which answers depend on a specific property or loan program. Keep a dated copy of the information you use. If a number changes, revisit the comparison rather than continuing with an outdated budget.

• Identify the decision: Ask what happens if closing moves beyond the lock expiration.
• Document the uncertainty: An extension or a changed application may affect the final cost.
