Can you afford a $300,000 mortgage?
A common lender guideline is the 28/36 rule: housing costs under 28% of gross monthly income, and all debt payments under 36%. The example payment of about $2,540 a month works out to a gross income of roughly $108,855 under the 28% test. Many loan programs allow higher ratios, but a payment that fits the guideline leaves room for repairs, savings, and everything else. Run your own numbers with the home affordability calculator and check your debt-to-income ratio.
With less than 20% down, conventional lenders add private mortgage insurance, roughly 0.5% to 1.5% of the loan a year, until you reach 20% equity (you can ask to cancel it then; it drops automatically at 22%). See what PMI costs and how to avoid it, and weigh the 15- vs. 30-year trade-off.

Calculation Formulas
P is the loan amount (home price − down payment), r is the monthly interest rate (annual APR ÷ 12), and n is the total number of monthly payments (years × 12). This yields the fixed principal-and-interest payment.
Example:
A $320,000 loan at 6.5% for 30 years: r = 0.0054167, n = 360 → M ≈ $2,023 per month in principal and interest.
Lenders escrow taxes and insurance, so your actual monthly payment adds one-twelfth of each annual cost to the principal-and-interest figure. PMI applies until you reach 20% equity.
Every payment over the full term, minus the amount you originally borrowed, is the lifetime interest cost — the number that reveals the true price of the loan.
Key Figures
| Figure | Value | Description |
|---|---|---|
| PMI removal threshold | 20% equity (80% LTV) | Point at which PMI can typically be cancelled on a conventional loan. |
| Automatic PMI termination | 22% equity (78% LTV) | Lender must remove PMI automatically per the Homeowners Protection Act. |
| 28/36 rule | 28% / 36% | Guideline caps: housing payment ≤ 28% of gross income; total debt ≤ 36%. |
