Car Payments and Home Buying Power: How $700/Month Can Cost You $100,000

How a Car Payment Could Cost You $100,000 in Home Buying Power

When you’re house hunting in today’s market, every dollar counts — and sometimes, it’s not your income holding you back from qualifying, it’s your monthly liabilities. One of the biggest culprits? Your car payment.

You wouldn’t believe how often I see someone with solid income, good credit, and savings — but they’re stuck because of that $700 a month car loan. The truth is, a $700 monthly payment can reduce your home purchasing power by roughly $100,000, depending on the interest rate and loan program.

Let’s unpack what this really means and how certain loan programs might allow you to work around it — or not.


🚗 The Math Behind Monthly Payments and Purchasing Power

In today’s rate environment (as of April 2025, the average 30-year fixed rate sits around 6.625%), $700 a month in mortgage payment roughly equals $100,000 in purchasing power. That means if you didn’t have that car loan on your credit report, you could potentially afford a home that’s $100,000 more expensive — and still have the same monthly mortgage payment.

Now, let’s say you’re carrying a car loan with a remaining balance of $15,000, and you’ve got $700/month going out the door on it. If you’re trying to buy a house and your debt-to-income ratio (DTI) is a little too tight, that car loan could be what’s blocking your approval — especially if you’re working with a lender who takes a rigid view on how installment debt is treated.


🏡 What Is “Paying Off Debt to Qualify”?

Some mortgage lenders might ask or even require you to pay off the car loan at or before closing to help you qualify for the house. It’s a strategy we call “paying off debt to qualify.” And it works — but it’s not always the only route.

If you’ve got the funds, yes, paying off a $15,000 car loan could increase your purchasing power and lower your DTI. But it’s not always the most efficient use of cash, especially if you’re tight on reserves or need that money for closing costs or your down payment.

Here’s where loan type really matters.


When You Don’t Need to Pay It Off: Installment Debt Guidelines by Loan Type

Let’s break it down by loan program. If you’re carrying an installment loan (like a car loan) with 10 or fewer payments remaining, here’s how the major loan types treat it:

Conventional Loans (Fannie Mae/Freddie Mac)

Installment loans can be excluded from your DTI if:

  • You have 10 or fewer payments left

  • The payment is not substantial (typically not more than 5% of your gross monthly income)

If the payment is considered “significant,” underwriters may still count it — even if there are only a few months left.

FHA Loans

The most conservative of the bunch. Installment debt may be excluded if:

  • There are 10 or fewer payments remaining, and

  • The total remaining payments are less than or equal to 5% of your gross monthly income

If the remaining balance is large or the payments push you over that 5%, FHA will count the debt against you.

VA Loans

The most flexible program. Installment debt with 10 or fewer payments left can usually be excluded, regardless of payment size — as long as the underwriter believes it doesn’t impact your ability to repay the mortgage. No strict 5% rule here.


🧠 What This Means for You

This is where working with the right lender makes all the difference. Not every lender interprets guidelines the same way. Some will count the debt regardless. Others — like myself — take a strategic look at your profile, understand the flexibility within the loan guidelines, and structure your loan to get you into the home you want without unnecessary roadblocks.

If you’re carrying a near-end car loan and trying to qualify, don’t assume you’ll have to pay it off — there’s a real possibility you won’t need to. Depending on your income, loan type, and what’s remaining on the note, we may be able to exclude that payment entirely, giving you the purchasing power you need.


💬 Final Thoughts

So, if you’re looking at homes and feel a little boxed in by your payment range, take a second look at your current liabilities — especially your car loan. The difference between qualifying or not might come down to less than a year of payments you’re already on the hook for.

And if you’re not sure what your DTI looks like or whether you can omit that payment — reach out. I’ll walk you through your options and help you figure out a plan that works for your goals.

Let’s keep it simple, smart, and strategic.

Refinancing Strategies to Reduce Credit Card Debt and Buy a Home

Refinancing Strategies to Reduce Credit Card Debt and Buy a Home If you’re sitting on…

When buying a home, it’s natural to want the lowest mortgage rate possible. But sometimes, chasing a slightly better rate from another lender—especially after your offer has already been accepted—can backfire in a big way. Let’s walk through a real-world scenario. You’ve got an offer accepted on a house. You’re working with a lender who has you approved, documents in underwriting, and a 21-day close of escrow in place. Everything is moving forward. Then you hear from another lender offering a rate that’s 0.25% lower, with slightly better closing costs. It’s tempting. But before you make a jump, here’s what you need to consider. Switching Lenders Comes with Time Costs When you pivot to a new lender mid-contract, they’ll need to: Re-underwrite your entire loan, Order a new appraisal, Disclose and sign new loan documents, Submit the file for final loan approval, Schedule and fund closing—all over again. This doesn’t happen overnight. Even in ideal circumstances, the new lender is likely going to need at least 25–30 days to close. If you’re in a fast-moving or competitive market, this is a real problem. Most sellers won’t grant a contract extension just because you’re switching lenders. So, what happens next? A Contract Extension Can Jeopardize Your Deal Asking for a contract extension means the seller must agree to delay closing. But that delay introduces risk—especially if the seller has backup offers or simply wants certainty. They may not grant the extension. Or worse, they could cancel the deal outright and take another buyer’s offer. Even if the seller agrees to extend, your earnest money and negotiation power could take a hit. And for what? A slightly lower rate that might save you $50 to $75 a month? Mortgage Rates Aren’t as Far Apart as You Think Here’s the truth: all mortgage lenders get their money from the same place—the bond market. The pricing differences between lenders usually range from 0.125% to 0.25% in rate on any given day. If one lender seems to be offering dramatically better pricing, the first thing you should ask is: How? Head over to FreddieMac.com and check the average 30-year fixed rate posted weekly. This is one of the most reliable benchmarks for where rates truly stand in the market. If a lender is quoting you a rate that’s well below that average, ask for the details: Are they charging extra points? Is this a teaser rate with a prepayment penalty? Is it based on a different loan product or risky structure? Often, what sounds “too good to be true”… is. Consider the Bigger Picture Think long-term. If you’re financing $600,000, a 0.25% lower rate may reduce your payment by roughly $75/month. But what if you lose the house and have to start over? That monthly savings doesn’t mean much if you’re outbid on your dream home or lose your deposit. Also, remember: you’re not going to keep this rate forever. Today’s homebuyers typically refinance when rates drop by about 0.75% or more. So if rates fall within the next year or two, you’ll likely be refinancing anyway. Instead of paying extra points now or risking the entire deal for a minor monthly savings, it may be better to accept a slightly higher rate—knowing you’ll refinance when the time is right. The Real Risk Isn’t the Rate—It’s the Delay When shopping for a home loan, don’t just ask, “What’s your rate?” Ask: Can you close on time? Is this rate sustainable or based on hidden costs? Will switching lenders delay or jeopardize my contract? A home purchase contract is a binding agreement between you and the seller to perform within a set timeframe. If you can’t meet those dates because you're chasing a slightly better rate elsewhere, you may want to reconsider if now is the right time to buy. Final Thoughts Yes, interest rates matter. But execution matters more. Before making a switch mid-transaction, talk to your lender. Have an honest conversation about pricing, timelines, and strategy. You might find that staying the course, securing the house, and planning to refinance later offers a better path to financial security. Want to Know Your Options?
