Your lender tells you you're approved for $400,000. That feels exciting, maybe even a little validating. But here's a question worth sitting with: just because you can spend $400,000, should you? The answer, for most people, is more nuanced than the pre-approval letter suggests.
How Lenders Calculate Your Number
Lenders use two primary ratios to determine your maximum loan amount. The front-end ratio (housing costs to gross income) typically targets 28% or less. The back-end ratio (all monthly debt payments, housing, car loans, student loans, credit cards, to gross income) targets 36–43%, depending on the loan program.
Notice I said gross income. Before taxes. Before retirement contributions. Before childcare, groceries, insurance premiums, and the dozen other things that consume your actual paycheck. A lender-approved payment of $2,800/month assumes you can absorb that on top of everything else, with no margin for the unexpected.
The Comfort Gap
In my experience, there's almost always a gap between what someone is approved for and what they'd actually feel comfortable paying each month. That gap, call it the comfort gap, is where financial stress lives.
A family approved for $400,000 may be genuinely happier and more financially secure in a $320,000 home. Not because they can't afford the higher payment, but because the lower payment gives them room to save, invest, travel, handle emergencies, and actually enjoy their lives without the constant low-grade anxiety of a stretched budget.
A Better Framework: Start With Your Budget
Instead of starting with the pre-approval and working backward, try this:
- Figure out your actual monthly housing budget. Not the lender's number, your number. What are you paying now for housing? What feels right to you, given your other financial goals?
- Work backward to a home price. Once you know your monthly budget, back-calculate what home price that supports, including Texas property taxes (typically 2–2.5%), homeowners insurance, and any HOA fees.
- Factor in the full picture. Don't forget maintenance (budget 1–2% of your home's value annually), utilities, and the lifestyle you want to maintain. A house payment that leaves no room for life isn't a win.
I've built a Comfort Range Finder tool that does exactly this, you enter your comfortable monthly budget, and it back-calculates the home price you should actually be shopping for, factoring in Texas property taxes and insurance. It takes the guesswork out of the equation.
Texas-Specific Considerations
Texas adds a wrinkle to this calculation because of our property tax rates. At 2–2.5% of assessed value, taxes on a $350,000 home can run $550–$730/month, significantly higher than many other states. Add homeowners insurance ($300–$400/month in many Houston-area areas), and your true monthly housing cost on a $350,000 home with 20% down could easily exceed $2,600–$2,800.
This is exactly why starting from your actual budget, not the lender's maximum, is the smarter approach. In Texas, the numbers work differently than buyers from other states expect.
