Payment breakdown

Amortization (yearly)

How much home can you afford?

Three budgets from your income and debts: the conservative 28/36 rule, a moderate 43% DTI, and the aggressive end of what underwriting allows.

Debts = minimum monthly payments on cards, auto and student loans, not utilities or groceries. PMI is added automatically when the down payment is under 20%.

Where each budget comes from

Refinance break-even

Monthly savings, months to recoup closing costs, and the lifetime-interest comparison most calculators skip. Resetting to a new 30-year term can lower the payment while raising total interest.

Total cost comparison

DSCR rental loan

Lender math: gross rent ÷ PITIA, qualifying on the lower of lease or market rent, with the interest-only variant and a max-loan solver at your target ratio. Investor cash flow shown separately: vacancy and management never enter the lender's ratio.
