So, you’ve decided to take the leap and buy a home. Congratulations! But have you given some thought to what kind of mortgage you can afford? It’s essential to consider both the price of the home and the monthly payment you’ll be responsible for.
Banks evaluate your ability to pay the monthly mortgage when deciding whether to grant you a loan. By applying the same principles that lenders use, you can narrow your search to homes that fit your budget, putting you one step ahead in the home-buying process.
So how do you determine how much mortgage you can afford? Read on to find out.
How Much Can You Spend on a Mortgage?
Buying your dream home is a significant milestone, but overextending yourself can turn that dream into a nightmare. Therefore, it’s crucial to establish how much you can realistically spend on a mortgage before you start shopping.
Banks typically use a metric called the Debt-to-Income Ratio (DTI) to assess your monthly expenses in relation to your income. While different banks may have varying methods for calculating DTI, they generally follow one of two approaches:
- Front-End DTI Ratio: This formula calculates the percentage of your mortgage payment relative to your total gross monthly income. To find your front-end DTI, divide your mortgage payment by your gross (pre-tax) monthly income. For example, if you earn $5,000 a month and your mortgage payment is $1,000, your front-end DTI would be 20%.
- Back-End DTI Ratio: This formula offers a more comprehensive view of your financial situation. To calculate your back-end DTI, sum all your monthly payments, including the mortgage, and divide that total by your gross monthly income. For instance, if your monthly bills total $1,000 and your mortgage is also $1,000, your back-end DTI would be 40% ($2,000 / $5,000).
Lenders have guidelines regarding how much of your monthly income should be allocated to mortgage payments. If your DTI exceeds these limits, your loan application may be denied. While the acceptable percentages vary by lender, they typically range from 36% to 50%. For example, Fannie Mae and Freddie Mac, which issue conventional mortgages, will not approve loans if a borrower’s back-end DTI exceeds 36%. This means that if your total monthly bills (including your mortgage) exceed 36% of your income, you may not qualify for a loan.
In addition to DTI, lenders also consider factors like job stability and credit score. If your DTI is high and your credit score is low, you may face challenges in securing a loan. Similarly, if you’ve recently started a job, even a compliant DTI may not provide the stability lenders seek.
How Can I Use DTI to Determine How Much I Can Spend on a Mortgage?
Just because a lender is willing to loan you money doesn’t necessarily mean you can afford it!
While some lenders allow a DTI of up to 50%, it’s essential to assess whether you can genuinely manage that percentage of your income for mortgage payments. You know your financial situation best, but it’s easy to get carried away while searching for your dream home. Here are some formulas to help you stay within your budget:
Formula #1: The 28/36 Rule
Many lenders adhere to the 28/36 rule when evaluating loan applications. According to this guideline, your front-end DTI should not exceed 28%, and your back-end DTI should not exceed 36%. This means your mortgage payment should be no more than 28% of your gross income, while your total debt (including the mortgage) should not exceed 36% of your gross income.
Formula #2: The 25% Post-Tax Model
If you prefer a more conservative approach, the 25% post-tax model is an excellent way to gauge your mortgage affordability. This model suggests that your mortgage payment should not exceed 25% of your after-tax income. For instance, if you earn $5,000 a month after taxes, your mortgage payment should ideally be capped at $1,250. This conservative approach provides more financial flexibility for emergencies.
Formula #3: High-DTI
While many lenders aim to ensure you can afford your mortgage, some may approve loans for borrowers with high DTIs, even up to 50%. For example, if you earn $5,000 and have $2,500 in monthly expenses, you might still qualify for a loan. However, relying on this formula could lead to financial strain in the future. A high DTI, combined with a mortgage, can quickly become unmanageable, especially if unexpected expenses arise.
Now that you have some guidelines, you can calculate your DTI and create a plan to search for homes within your budget. Utilizing an online mortgage calculator can help you determine your true price range. By adhering to these guidelines, you’ll likely find that dream home without the stress of financial strain.
