Preparation and pre-approval
It starts with a conversation about your numbers — income, debts, savings, timeline. That is where you find out what is realistic, and where any preparation worth doing gets identified.
Pre-approval is the next step: a real review of your file that produces a letter you can put behind an offer. It is based on your information at a point in time, not a final commitment, and it has limits worth understanding before you rely on it. Getting pre-approved before you shop is what turns “I hope I can afford this” into a number.
