A pre-approval can help you see a possible purchase range and ask better questions about payments, down payment, and conditions. It is a planning tool, not a reason to stretch your comfort level.

The best question is personal.
Instead of only asking what amount you can qualify for, ask what monthly payment supports your savings, family plans, and peace of mind.
