Home Affordability Calculator

How Big a House
Can I Buy?

Most calculators only look at income. This one factors in your long-term wealth goals — so you can buy a home without compromising your financial future.

Buy the biggest home that still fits your future.

This calculator looks beyond lender approval. It estimates what you can buy after factoring in taxes, property costs, debt, your down payment, and the liquid wealth you want to preserve.

Shows conservative, balanced, and aggressive home-price ranges.
Accounts for assets, cash cushion, gifts, HOA fees, and taxes.
Helps avoid being approved for more house than you should actually buy.
