If you are like many first time homebuyers, you are excited and eager to purchase your first home. Yet, your funds are somewhat limited, as you are just starting out. How do you calculate how much to spend on your first home?
One key calculation utilized by lenders is your debt-to-income ratio. Lenders use this ratio to determine how much mortgage debt you can handle and, consequently, the maximum loan amount you will be offered. This ratio is based on how much personal debt you carry, (including auto loans, student loans and minimum credit card payments) in relation to how much you earn, or your gross income.
To determine this ratio, you’ll need to do a little math.
1. First, determine your monthly gross income. Remember, your gross monthly income is the before-taxes total earnings from the month, not how much money you actually take home after paying taxes, social security and other deductions. Multiple your monthly gross income by .36, which will give you the monthly debt payment number that experts have identified.
2. Next, add up all your family’s fixed monthly debt expenses, such as car payments, your minimum credit card payments, student loans and any other regular debt payments.
3. Then, subtract the second number (your fixed monthly debt expenses) from the first (your debt payment number) to determine the maximum mortgage payment you can make per month. Keep in mind that this number includes private mortgage insurance, homeowner’s insurance and property taxes.
To determine the price of home you can afford based on this amount, use an online home affordability calculator.
Finally, in addition to the above calculations, sit down and go over your monthly budget and make sure you feel very comfortable with your estimated monthly mortgage payment. If your mortgage payment needs to be lower to give you flexibility in your budget, reduce it accordingly.
