Buying on One Income: How to Set a Payment You Can Actually Live With
Buying a home on one income is not automatically risky just because there is only one paycheck.
The bigger risk is building your home-buying plan around a payment that uses nearly all of that paycheck.
A lender may approve you for a certain amount, but approval and affordability are two different things. The goal is to find a payment that works not only on paper, but also with your real life, your savings goals, and the unexpected expenses that come with owning a home.
Before you choose a price range, build your own personal payment ceiling using five numbers.
1. Start With Your Monthly Take-Home Pay
Use the amount that actually lands in your bank account each month—not your gross income.
Your take-home pay already accounts for things such as taxes, insurance, and retirement contributions, giving you a more realistic starting point for your budget.
2. Subtract Your Fixed Obligations
Look at the expenses that have to be paid every month.
This can include:
- Car payments
- Student loans
- Credit card minimum payments
- Child care
- Child support or other support obligations
- Insurance
- Other recurring monthly commitments
These expenses are already taking a portion of your income before you add a mortgage payment.
3. Account for Normal Life
This is where it helps to be honest with yourself.
Estimate what you normally spend on groceries, gas, health-related costs, subscriptions, personal spending, entertainment, and the other everyday expenses that make up your life.
Don’t build your budget around your best month.
Use a realistic average.
4. Plan for the Costs of Being a Homeowner
Your mortgage payment isn’t the only new expense that comes with owning a home.
Think about utilities, routine maintenance, lawn care, and a repair or maintenance buffer.
These costs can vary from one home to another, so it’s important to consider them separately from the mortgage payment.
5. Protect Your Savings
Decide how much you want to continue saving each month after you become a homeowner.
Also determine the minimum amount of cash you are comfortable having left after closing.
Buying a home shouldn’t mean draining your savings just to make the purchase work.
Now Calculate Your Personal Payment Ceiling
Start with:
Take-home pay
− Fixed obligations
− Normal living expenses
− Future homeowner costs
− Monthly savings target
= Your personal ceiling for the total housing payment
Once you have that number, that’s where your mortgage loan officer can help.
Instead of looking only at the purchase price or interest rate, have your MLO price the home using the full monthly housing payment, including:
Principal and interest
Property taxes
Homeowners insurance
Mortgage insurance, when applicable
HOA dues, when applicable
That gives you a much clearer picture of what the home will actually cost each month.
Approved Doesn’t Always Mean Comfortable
A loan approval answers the question, “Can you qualify for this mortgage based on the lender’s guidelines?”
Your personal budget answers a different question:
“Does this payment allow me to own this home and still live the life I want?”
Those two numbers don’t always have to be the same.
If the verified total housing payment is above your personal ceiling, the home may simply be too expensive for your plan—even if you qualify for the loan.
The goal isn’t necessarily to buy the most expensive home you can qualify for.
It’s to build a homeownership plan that leaves room for saving, maintaining your home, handling the unexpected, and enjoying life after the closing.
