When it comes to buying a home, one of the most important factors to consider is how much mortgage you can afford. With an annual income of $100,000, it’s crucial to determine a realistic budget that allows you to comfortably make your monthly mortgage payments while still meeting your other financial obligations. In this article, we will explore various aspects of affordability and provide insights to help you understand what mortgage you can afford on a $100,000 income.

Factors to Consider

Debt-to-Income Ratio: One of the key factors that lenders consider when determining your mortgage affordability is your debt-to-income ratio (DTI). This ratio compares your monthly debt payments to your gross monthly income. Generally, lenders prefer a DTI ratio of 43% or lower. To calculate your DTI, add up all your monthly debt payments (including credit cards, car loans, student loans, etc.) and divide it by your gross monthly income.

Down Payment: The down payment you can afford will also impact the mortgage you can obtain. While it’s possible to secure a mortgage with a low down payment, a larger down payment can help reduce your monthly mortgage payments and potentially qualify you for better interest rates.

Interest Rates: Interest rates play a significant role in determining your monthly mortgage payments. Higher interest rates will result in higher monthly payments, while lower interest rates will reduce your monthly expenses. It’s essential to stay informed about current interest rates and consider their impact on your budget.

Other Expenses: In addition to your mortgage payment, you need to consider other homeownership expenses such as property taxes, homeowners insurance, and maintenance costs. These expenses can vary depending on your location and the size of the property.

Calculating Affordability

To determine what mortgage you can afford on a $100,000 income, it’s crucial to consider your DTI ratio and other expenses. Here’s a general guideline to help you estimate your affordability:

1. Calculate your maximum DTI ratio: Multiply your gross monthly income by 0.43 to determine the maximum amount you should allocate towards debt payments.

2. Subtract your existing monthly debt payments: Subtract your current monthly debt payments from the maximum amount calculated in step 1. The remaining amount represents the maximum mortgage payment you can afford.

3. Estimate property taxes and insurance: Research the average property taxes and insurance costs in your desired area. These expenses can vary significantly, so it’s important to obtain accurate estimates.

4. Consider maintenance costs: It’s recommended to set aside 1-2% of the home’s value annually for maintenance and repairs.

5. Use an online mortgage calculator: Utilize online mortgage calculators to estimate the mortgage amount you can afford based on your down payment, interest rates, and the maximum monthly payment determined in step 2.


Determining what mortgage you can afford on a $100,000 income requires careful consideration of your debt-to-income ratio, down payment, interest rates, and other homeownership expenses. By calculating your affordability and considering these factors, you can make an informed decision about the mortgage that fits within your budget. Remember to consult with a mortgage professional to get personalized advice based on your specific financial situation.
