If you want to buy a house in the next 6 to 12 months, one of the worst things you can do is finance a vehicle right before applying for a mortgage.
And honestly, I’ve seen this mistake cost buyers their approval.
A car payment may not seem like a big deal when you are at the dealership, but mortgage lenders look at it very differently. When you apply for a home loan, your lender has to calculate your debt-to-income ratio, also called DTI.
That new car payment could be the difference between qualifying for a house and getting denied.
Why Buying a Car Can Hurt Your Mortgage Approval
Your debt-to-income ratio compares your monthly debt payments to your qualifying monthly income.
So if you finance a car and add a $600, $700, or $800 monthly payment, that payment gets counted against you when you apply for a mortgage. According to Experian, the average new car payment is around $734, and the average used car payment is around $525, which can make a real difference in mortgage qualifying.
Here’s the thing: mortgage lenders do not just care that you can make the car payment.
They care how that payment affects your ability to afford the mortgage payment, property taxes, homeowners insurance, HOA dues, and other monthly debts.
So if you are serious about buying a house soon, be very careful before financing anything major.
Avoid Financing Big Purchases Before Buying a Home
If your goal is to buy a home within the next year, try not to open new debt unless you absolutely have to.
That includes cars, furniture, appliances, personal loans, credit cards, and “buy now, pay later” financing.
Even if you can afford the payment, the lender still has to count it.
Don’t overcomplicate it: before taking on new debt, talk to a mortgage lender first. A five-minute conversation could save you from creating a problem that takes months to fix.
Work on Your Credit Early
The next thing you want to do is work on your credit score.
Different loan programs have different credit requirements. FHA allows down payments as low as 3.5% for eligible borrowers, and FHA guidelines are often more flexible than conventional loans.
That said, having a stronger credit score may give you more options, better pricing, and an easier approval process depending on the program and lender.
A good goal for many buyers is to get your score as strong as possible before you apply. Even small improvements can sometimes make a difference in your rate, mortgage insurance, or loan options.
Save More Than Just the Down Payment
A lot of buyers only think about the down payment.
But that is not the only money you may need.
For example, FHA loans may allow a down payment as low as 3.5% for qualified buyers. On a $300,000 home, that would be $10,500. But you may also need money for closing costs, inspections, appraisal, moving expenses, furniture, repairs, and cash reserves.
That is why I usually encourage buyers to save more than the bare minimum whenever possible.
A simple goal is to save around 5% of your estimated purchase price if you can. On a $300,000 home, that would be about $15,000. That gives you more breathing room instead of using every dollar just to get to closing.
Down payment assistance programs may also be available depending on your income, location, loan program, and state or county guidelines. But even with assistance, having some cash saved can make the process smoother.
Talk to a Mortgage Lender Before You Are Ready
This is probably the biggest one.
Do not wait until you need to buy the house to talk to a mortgage lender.
If your lease is ending in six months, talk to someone now. If you want to buy before the end of the year, talk to someone now. If you are not sure whether you qualify, talk to someone now.
Getting pre-approved does not mean you have to buy a house immediately.
It simply helps you understand where you stand.
A good mortgage lender can review your credit, income, debts, savings, and timeline, then help you build a roadmap. Maybe you are ready now. Maybe you need to pay down a credit card. Maybe you need to avoid financing a car. Maybe you need to save more cash.
Either way, it is better to know early.
Final Thought
If you want to buy a house in the next 6 to 12 months, protect your mortgage approval.
Do not finance a vehicle or take on major new debt without checking with your lender first. Work on your credit, save more than the minimum, and get a mortgage game plan before you are under pressure to move.
Buying a house is a lot easier when you prepare early.
