When buying a home, understanding how much mortgage you can afford is crucial. Lenders assess your
debt capacity to determine how much you can borrow, but just because you are pre-approved for a certain amount doesn’t mean you should borrow the maximum. Instead, it’s important to create a realistic budget to ensure long-term financial stability.
The 28/36 Rule for Home Affordability
Lenders use debt-to-income ratio (DTI) to assess how much home you can afford. To calculate your DTI, divide your total monthly debt payments by your gross monthly income. This figure helps lenders determine your ability to manage additional debt.
A widely used guideline, the 28/36 rule, sets two key limits:
- 28% Rule: Your total housing costs (mortgage, property taxes, homeowners insurance) should not exceed 28% of your gross monthly income.
- 36% Rule: Your total debt payments (including mortgage, car loans, student loans, and credit cards) should not exceed 36% of your gross monthly income.
Example Calculation
If your gross monthly income is $5,000:
- Your mortgage payment should stay below $1,400 (28% of income).
- Your total debt payments should remain under $1,800 (36% of income).
Adhering to these limits helps keep your mortgage affordable and ensures room for other expenses.
Other Key Factors That Impact Affordability
Beyond your DTI, several other factors affect how much home you can afford:
1. Mortgage Term
The length of your loan term impacts your monthly payment. A 30-year mortgage typically has lower monthly payments than a 15-year mortgage, but you’ll pay more in interest over time.
2. Interest Rate
The interest rate directly influences your monthly mortgage payment. Lenders determine the rate based on factors like your credit score, down payment, and loan type. A lower interest rate leads to lower monthly payments.
3. Monthly Budget
In addition to mortgage payments, review your entire budget. Consider savings, emergency funds, and other financial obligations to ensure your mortgage fits comfortably within your financial situation.
4. Cash Reserves
Cash reserves refer to how many months of mortgage payments you could cover using your savings in case of unexpected events, like job loss. Most experts recommend having at least two to three months’ worth of mortgage payments saved.
5. Down Payment
You don’t need 20% down to buy a home. Conventional loans backed by Fannie Mae and Freddie Mac allow for as little as 3% down. However, putting more money down may lower your interest rate, reduce your monthly payments, and eliminate mortgage insurance, which can lower your overall costs.
6. Extra Costs
Along with your down payment, consider the following additional costs:
- Closing Costs (usually 2-5% of the loan amount)
- Property Taxes (varies by location)
- Homeowners Insurance (required by lenders)
