Run the numbers before

the conversation.

Get a realistic picture of your monthly payment, what you can afford, whether refinancing

makes sense, or if it's time to stop renting. No login required. No data collected.

Estimate your monthly payment including principal, interest, taxes, insurance, and PMI. Adjust the home price, down payment, and rate to see how they affect your bottom line.

How Much Can I Afford

Enter your income and debts to see the maximum home price that fits your budget. We'll calculate based on standard debt-to-income guidelines that lenders actually use.

Find out how many months it takes for your monthly savings to cover the cost of refinancing. If you plan to stay past the break-even point, refinancing could save you thousands.

Rent vs Buy

Compare the true cost of renting against buying over 3, 5, 7, or 10 years. Factors in equity, home appreciation, rent increases, maintenance, and your total wealth at the end.

Want real numbers, not estimates?

Calculators give you a starting point. A conversation gives you the actual picture — your rate, your programs, your options. No pressure, no obligation.

These calculators are for educational and estimation purposes only. They do not constitute a loan offer, pre-approval, or commitment to lend. Actual rates, payments, and terms will vary based on your credit profile, loan program, property type, and other factors. Brondt Cook Group | One Mortgage | NMLS #13988 | Equal Housing Lender.
