What is a Mortgage Affordability Calculator?

Recommendations & Key Insights
Financial Analysis
- At a moderate 40% DTI, you could afford up to $449,943 — often considered a comfortable, sustainable target.
- At your selected Aggressive scenario (48% DTI), your maximum is $547,349.
- Your down payment of $30,000 represents 5.5% of the aggressive-scenario home price.
Risk Assessment
- Estimated PMI of $202.63/mo is included in the aggressive scenario (rate ~0.47%/yr) — a larger down payment would reduce or eliminate it.
- Your existing monthly debts of $450 reduce your available housing budget before any mortgage payment is considered.
- Stretching from the conservative to the aggressive scenario buys $221,548 in additional home price, but leaves less room for other financial goals.
- This tool estimates from income, debts, and target housing costs only — it doesn't account for closing costs, cash reserves, or full loan-program underwriting.
Next Steps
Based on your scenario, here's what we'd suggest next:
- Review your monthly budget to decide which DTI comfort level fits your goals.
- Get a verified pre-approval to confirm your actual qualifying amount and rate.
- Ask about down payment assistance programs, or how a larger down payment would change your PMI.
- Contact a Mortgage Brothers loan officer to review your options and confirm eligibility.
