Financial guide for first-time home buyers

A home is the largest purchase of your life — know your numbers before you fall in love with a house.

First-time home buying is exciting and financially consequential in equal measure. The wrong purchase — too much house, underfunded down payment, high-rate mortgage — can constrain your finances for a decade. The right purchase, made with clear eyes, builds equity and stability. Start with the numbers: how much can you truly afford (not what a lender will approve), what your credit score qualifies you for, and whether now is the right time or if waiting 6–12 months to save more would meaningfully improve your terms. A 1% lower mortgage rate on a $500,000 home saves $175,000 over 30 years.
