Stop Buying At Your Max Pre-Approval Amount

If you make around $100,000 a year, or you and your partner combine to that, there are two very different numbers you need before you look at a single house. The first is what a lender will approve you for. The second is what you can actually afford to live with. Your lender's number is built on their risk using your debt-to-income ratio. Your comfortable number is built on your take-home pay and your goals. Those two numbers are usually thousands of dollars apart.

I'm Ian, a mortgage broker, and I work with first-time buyers, investors, and business owners every day. I have watched the same mistake play out over and over. A lender hands someone a pre-approval letter, the buyer shops right at the tippy top of it, and a few months after closing they are house poor. Beautiful home, zero breathing room. Let's make sure that is not you.

What is the lender's number and why is it too high?

The lender's number comes from your pre-approval. It is the most a lender is willing to hand you. It is not a bad number, it just is not the one you want to go shopping with, because it is not built around your life. It is built around the lender's risk.

Lenders don't only look at how much you make. They look at how much debt you carry compared to your income. That is your debt-to-income ratio, or DTI. They take your minimum monthly debt payments, like your car payment, minimum credit card payments, and student loans, and stack that against your gross monthly income. Gross means before taxes and before anything comes out. See the problem? You do not spend your gross income. You spend what actually hits your bank account. But the lender's math runs on the bigger number.

How do front-end and back-end DTI work?

There are two ratios in play. Your front-end ratio is just your housing payment as a percentage of your income. Your back-end ratio is your housing payment plus all your other debts as a percentage of your income. The lender runs both, takes the lower result, and that becomes your max payment. The Consumer Financial Protection Bureau has good plain-language material on how debt-to-income affects your borrowing.

Every loan program has its own limits. On an FHA loan, best-case ratios can stretch toward 47% on the front and around 57% on the back. Conventional loans mostly lean on the back end, which can climb near 50%. USDA keeps you on a tighter leash. VA barely uses DTI at all and instead looks at residual income, the cash left over after your bills, which is why VA loans can go higher.

Read those numbers back. 47%. 50%. That is the lender saying you can spend nearly half your pre-tax income on housing. Would that be smart to actually do? In most cases, no.

Why do self-employed buyers get approved for less?

This one trips up business owners the most. Lenders do not qualify you on what you deposit. They qualify you on what you net after write-offs on your tax returns. So your approval number can feel low compared to how you actually live. That makes knowing both of your numbers even more important if you are self-employed.

What counts as debt in the calculation?

Car loans and leases, the minimum payment on your credit cards, student loans, and child support or alimony if you pay it. Rule of thumb: if it shows up on your credit report, it is in the math.

What does not count? Your rent, utilities, phone bill, groceries, gas, and car insurance. None of that is on your credit report, so the lender does not see it. That is kind of wild, because that stuff is your actual life, and it is the exact stuff that gets hard to pay when your mortgage payment is too high.

When does going up to your max make sense?

There are a few times going near the max works. If it is just you on the loan because your partner's credit is not ready, but you have household income helping carry the payment. If you have a roommate covering part of it who is not on the loan. If you have a raise or bonus you are genuinely sure about. The theme is simple. You can stretch when you have something real backing it up. What you do not want is to stretch to the ceiling with nothing behind it but hope.

How do I find my comfortable number?

There are a hundred affordability rules out there. The 28/36 rule. The 25% of take-home rule. The three-times-income rule. None are fully right or wrong, because the right number fits your budget and your goals, not a formula.

Here is where I start most people. Take about 33% of your gross income. On a $100,000-a-year example, that lands you around a monthly payment that, depending on rates, taxes, and insurance, points you toward a moderate purchase price. That is a starting line. If you want to kill debt fast or travel and enjoy your money, go under it. If a specific house in a specific spot matters most and you decided that on purpose, maybe you go up.

What is the practice-payment test?

This test is powerful and almost nobody does it. Say you pay a certain amount in rent now, but the home you are eyeing costs more per month. Before you commit, test the gap. Open a separate savings account and every month move that difference into it while you keep paying rent as normal. You are making practice payments.

Do that for two or three months and pay attention. Is it comfortable or stressful? If it is comfortable, you proved you can handle the real payment. If it is stressful, you saved yourself from an expensive mistake and you adjust your number down. Either way, that savings account becomes your down payment. You cannot lose.

What is the payment behind the payment?

When people picture a mortgage, they picture principal and interest. But your real payment is more. It is principal and interest, plus property taxes, plus homeowners insurance, plus mortgage insurance if you have it, plus HOA dues if the place has them. In many markets, taxes and insurance are a real chunk that can make two identical-looking homes cost very different amounts.

When you stare at a friendly estimated payment online, scroll down and check the inputs. Those calculators often assume 20% down by default, and most buyers are not putting that down. Check the real inputs every single time. Then budget for what renting hid from you: utilities, maintenance and repairs (a rough rule of thumb is about 1% of home value a year), and the fact that taxes, insurance, and HOA dues tend to creep up.

Does my first home have to be my forever home?

No. Many people build real wealth with a stepping-stone approach. You buy the home that checks maybe half your boxes, live in it, and pay it down. Historically, over the long run and not as a promise, home values have risen around 4% a year on average. A few years in, your balance is lower and your value is likely higher. That gap is your equity, and it can become the down payment on a bigger home later.

So buy a home for your life, not for someone else's. When you scroll past gorgeous homes online and wonder how everyone affords them, a lot of those owners are maxed out and stretched thin. You are not behind. You are just seeing the highlight reel.
