How Much House Can I Afford?
by Mark Munzenberger, Financial Education Manager, UMCU
Determining how much house you can afford is a balance between what a lender is willing to capitalize and what your personal monthly budget can actually sustain. While lenders often look at your gross income and a debt-to-income ratio (DTI) of up to 45%, a more sustainable approach for most homeowners is the 28/36 rule, which suggests spending no more than 28% of your gross income on housing costs. To find your true "comfort zone," you must look beyond the purchase price and factor in the total cost of ownership, including interest rates, property taxes, homeowners insurance, and ongoing maintenance. By weighing these mathematical rules against your unique lifestyle goals—like future family plans or career changes—you can move forward with a monthly payment that fits your life as well as it fits your home.
Finding the Right Mortgage in Southeast Michigan: Who Decides Your Budget?
Who Decides on What I Can Afford Each Month?
There are many things to consider when purchasing a home.
In short – you. It’s important to separate the underwriting process used with the mortgage application from your personal household budget. After submitting a mortgage application, your lender will respond with the maximum loan amount you qualify for, based on income, current debts, credit score, and a few other factors. Lenders will use your gross income, which is the total amount of money an individual earns in a month before any deductions, such as taxes, insurance, or retirement contributions.
Factoring in Other Debt - The 28/36 Rule
The debt-to-income (DTI) ratio used in mortgage underwriting is the percentage of your gross monthly income that goes towards paying monthly debts, including the new mortgage payment, credit cards, and other loans. Lenders use the DTI to assess your financial ability to manage the monthly mortgage payment based on a pre-approval amount.
While many lenders accept applicants with a DTI of up to 45%, according to the well-known 28/36 rule, you should spend no more than 36% of your gross monthly salary on housing, credit cards, car loans, and other debts. Of that 36%, no more than 28% should be allocated towards the mortgage and other housing costs.
My Monthly Budget - The 35% Rule
A common rule of thumb used by budget and housing counselors is that homebuyers should commit no more than 35% of their net monthly income to overall housing expenses, including the mortgage payment and utilities. Net monthly income, often called "take-home pay," is the actual amount of money you receive in your bank account after all deductions are taken from your gross pay. Especially when looking for low-interest home loans, knowing your net limit is vital.
The Borrower Makes the Final Decision
Each borrower is different, and deciding on exactly how much to borrow (which dictates the monthly payment) should be based on individual factors. Working with an Ann Arbor mortgage lender can help you tailor these decisions to our local cost of living. Consider these questions:
Are you planning to have children now or in the future, which would increase monthly expenses?
Will household income decrease in the future based on a change of employment status or a retirement?
Do you have plans to return to school?
Are there other planned major expenses such as transportation, charitable giving, or health care, which could impact the monthly cash flow?
Finally, owning a home will always come with maintenance and upkeep responsibilities which will occur regularly.
Creating a solid budget makes home affordability achievable!
What Goes into Your Mortgage Payment?
Your monthly payment will be influenced by a variety of factors, such as:
Mortgage principal and interest - Your lender will charge interest in the form of a percentage of the total principal you borrowed. Higher interest rates result in higher monthly payments.
Property taxes and homeowners insurance – It’s standard practice for lenders to set up an escrow account for property taxes and insurance payments to be deposited into.
Private mortgage insurance - If you put less than 20% down on a conventional mortgage, you’ll have to pay private mortgage insurance.
In summary, borrowers need to be empowered to establish a monthly housing payment that they feel they can comfortably afford, both now and into the future.
