Educational tools

Run your own numbers first.

Every calculator here is for educational purposes only: your numbers in, a clearer picture out. Nothing is a quote, a rate, or an application, and nothing you type is sent anywhere. When you want the real version, I'm easy to reach.

How much house can I afford?

A working price range from your income, debts, and down payment. Perfect for buyers who want a realistic starting point before falling in love with a listing that might be a stretch too far.

Rent vs buy

A simple first-year side-by-side, including the part of a payment that builds your own equity. Good for data-driven renters, though owning has plenty of intangible benefits this won't capture.

Next step

Calculators start conversations. They don't finish them.

Every tool here leaves out things an underwriter won't: credit, program rules, property details, mortgage insurance, timing. When a result surprises you, that's the moment to send it to me.

Nothing here is a quote, an offer, an interest rate, an APR, a pre-approval, or a commitment to make a loan. Your actual numbers depend on full underwriting and credit approval.
