Let's get something out of the way right now: the bank does not care about your Netflix subscription. They don't care about your grocery bill, your gym membership, your kid's travel soccer fees, or the fact that you like eating at a restaurant more than twice a year. When a lender tells you that you're "approved" for a certain amount, they're answering one question and one question only can this person make payments without defaulting on the loan?
That is a very different question from can this person make payments and still enjoy their life?
And that gap between what a lender will let you borrow and what you should actually spend is where a lot of homebuyers get into trouble. So let's break this down honestly. No sugarcoating. No sales pitch. Just math, real talk, and some scenarios you can actually use.
The golden rule: 28/36
If you've done any Googling on this topic, you've probably run into something called the 28/36 rule. It's been the standard guideline in mortgage lending for decades, and for good reason, it works. The concept is straightforward: spend no more than 28% of your gross monthly income on housing costs, and keep your total debt payments (including the mortgage) under 36%.
So if your household pulls in $7,000 a month before taxes, the 28% rule says your total housing payment that includes principal, interest, property taxes, insurance, and any HOA fees should stay at or below $1,960. And your combined monthly debt load (car payment, student loans, credit cards, plus the mortgage) shouldn't top $2,520.
Yes, lenders calculate based on your pre-tax income. But here's the thing: you don't live on your gross income. You live on what actually hits your bank account after taxes, insurance premiums, and retirement contributions. A household grossing $8,000/month might only take home $6,000. The 28/36 rule is a solid starting point, but the smartest buyers run the numbers against their net income, too. If 28% of your gross pay is $2,240, but that represents 37% of your take-home pay, you're going to feel it.
What your lender will approve vs. what you should spend
Here's where things get interesting and a little uncomfortable. In 2026, many conventional mortgage programs will approve borrowers with total debt-to-income ratios pushing into the mid-40s. Some automated underwriting systems will go as high as 50% for applicants with strong credit and solid reserves. FHA loans allow up to 43% on the back end, and VA loans use a 41% benchmark but can stretch further with compensating factors.
On paper, that means a lender might happily approve you for a monthly payment that eats up nearly half your gross income. That's not a recommendation. That's a risk assessment. They're betting you won't default. Whether you'll be able to save for retirement, take a vacation, or handle a $3,000 HVAC repair in July without a panic attack? That's not really their problem.
A mortgage approval is a ceiling, not a target. The smartest buyers aim well below it.
Dave Ramsey's team recommends an even more conservative approach: keep total housing costs under 25% of your take-home pay (not gross), and go with a 15-year fixed mortgage if possible. That's aggressive; most people won't do it, but it's worth knowing the spectrum. The sweet spot for most families is somewhere between "the bank's maximum" and "Dave Ramsey's ideal." Find where you're comfortable and build some breathing room in.
Let's run real numbers
Enough theory. Let's see what this actually looks like using today's market conditions. As of early April 2026, the average 30-year fixed mortgage rate is hovering around 6.4% to 6.5% according to Freddie Mac's latest Primary Mortgage Market Survey. The Texas median home price sits around $334,000 based on the Texas Real Estate Research Center's 2026 forecast, though that varies significantly by metro area, and here in Fort Worth, the median listing price is tracking a bit higher.
Here are two realistic scenarios:
The careful first-time buyer
The move-up buyer with room to breathe
The Texas property tax factor
If you're buying in Texas and especially here in the DFW metroplex, there's a wrinkle that catches a lot of people off guard: property taxes. Texas has no state income tax, which is great, but property taxes are among the highest in the country. The Tax Foundation reports that the statewide effective rate on owner-occupied homes is about 1.36%, but depending on your county, it could be much higher. In fast-growing suburban counties like Collin, Fort Bend, and Williamson, effective rates can push past 2%.
What does that mean in dollars? On a $340,000 home with a 1.8% effective rate, you're looking at roughly $6,120 a year or about $510 a month just in property taxes. That's on top of your mortgage payment. A lot of online calculators underestimate this, especially for Texas buyers. Always plug in your county's actual rates, not the national default.
If the home is your primary residence, you're eligible for a $100,000 homestead exemption on school district taxes. On a $340,000 home, you'd only be taxed on $240,000 for the school portion of your bill. That can mean real savings, sometimes $1,000 or more per year. File for it immediately after closing. It won't apply automatically.
The costs everyone forgets
Your mortgage payment is not the finish line; it's just the starting gun. Here are the expenses that blindside new homeowners every single time:
Closing costs. Expect 2% to 5% of the purchase price. On a $300,000 home, that's $6,000 to $15,000 out of pocket at the closing table in addition to your down payment. This covers things like title insurance, appraisal fees, lender origination fees, and prepaid taxes and insurance.
Home maintenance. The industry rule of thumb is 1% to 2% of your home's value per year. For a $340,000 home, that's $3,400 to $6,800 annually. And it's not evenly distributed. Some years you'll spend almost nothing, and then your HVAC dies in August, and you're writing a $7,000 check. North Texas foundations, in particular, are notorious for needing attention due to the expansive clay soil in the region.
Private mortgage insurance (PMI). Put down less than 20%, and you'll pay PMI, typically 0.5% to 1% of the loan amount per year. On a $270,000 loan, that's an extra $112 to $225 a month. It's not permanent; you can request removal once you hit 20% equity, but it adds up in those early years.
Homeowners insurance. Texas rates tend to run higher than the national average due to hail, wind, and storm risk. Expect to pay anywhere from $2,000 to $4,000+ per year, depending on coverage, location, and the age of your roof.
The stuff you didn't know you needed. A lawn mower. Window blinds. A water softener. The weird adapter for the dryer hookup. That first trip to the hardware store after closing will cost more than you think. Budget at least $3,000 to $5,000 for move-in essentials and small surprises in the first six months.
How interest rates change everything
This is the part that makes people's eyes glaze over, but stick with me, it's arguably the most important piece of the puzzle. A small shift in your interest rate has a dramatic impact on what you can afford.
| Interest rate | $2,000/mo buys you… | Total interest paid (30-yr) |
|---|---|---|
| 5.5% | ~$352,000 loan | ~$368,000 |
| 6.0% | ~$334,000 loan | ~$386,000 |
| 6.5% | ~$316,000 loan | ~$404,000 |
| 7.0% | ~$300,000 loan | ~$420,000 |
Look at that table again. Between a 5.5% rate and a 7.0% rate, the same $2,000/month payment gets you $52,000 less house, and you'll pay over $50,000 more in total interest. That's not a rounding error. That's a swimming pool. That's two years of college tuition. Your rate matters enormously, which is why shopping multiple lenders, not just going with whoever your agent recommends, is one of the highest-ROI moves you can make.
A smarter way to think about it
Here's my challenge to you: forget about the maximum for a minute. Instead of asking "what's the most I can afford?", flip the question around. Ask yourself: what monthly payment would let me still do everything else I want to do?
Start with your actual take-home pay. Subtract the things you refuse to give up: retirement savings, your kids' activities, a reasonable food budget, and some fun money. What's left? That's your honest housing budget. Work backward from there to a price range, and you'll land on a number that's actually sustainable.
Because here's the thing that no calculator will tell you: the right home at a comfortable price beats the "dream home" that keeps you up at night. You should own your home; your home should not own you.
Your action plan before you start shopping
Pull your credit report. You're entitled to a free one from each bureau annually at AnnualCreditReport.com. If your score is below 680, spend three to six months cleaning it up before you apply. A higher score means a better rate, and as we just showed, even half a point makes a real difference.
Calculate your real debt-to-income ratio. Add up every monthly debt payment, car, student loans, credit cards, and personal loans, and divide by your gross monthly income. If you're already above 25%, you've got less room than you think.
Save beyond the down payment. You need money for closing costs (2–5% of the purchase price), a moving budget, those first-month surprises, and an emergency fund. Ideally, you want three to six months of total expenses in reserve after you close. Buying a home with zero cushion is a recipe for stress.
Get pre-approved, not just pre-qualified. Pre-qualification is an estimate. Pre-approval means a lender has actually verified your income, assets, and credit. It's the difference between a guess and a commitment, and sellers take it much more seriously.
Run the stress test. Before you commit, ask yourself: could I still make this payment if my income dropped by 20%? If property taxes go up next year? If rates rise and I can't refinance? If the answer is "barely" or "no," you're too close to the edge.
The bottom line
Buying a home is probably the biggest financial decision you'll ever make, and the excitement of house hunting can make it dangerously easy to overextend yourself. The math is your friend here. Run the 28/36 rule as a baseline, adjust for your actual take-home pay and lifestyle, account for the full cost of ownership (not just the mortgage), and leave yourself a buffer for the unexpected.
In a Texas market where the median home price sits around $334,000 and mortgage rates are in the mid-6% range, being realistic about what you can handle isn't pessimism, it's wisdom. The buyers who do this well are the ones who enjoy their homes for years without regret. And that's the whole point, isn't it?
You've got this. Take your time, run your numbers, and make your move the right one.
