How Much House Can I Actually Afford? A No-Nonsense Guide to Your Mortgage Budget
I’ll never forget the night I sat on my couch my coffee gone cold and staring at a spreadsheet that was supposed to tell me if I could afford my dream home. My stomach churned could I swing the payments without sacrificing my sanity? If you are asking, “How much mortgage can I afford?” you’re probably feeling that same mix of excitement and dread. Don’t worry. This guide will walk you through figuring out what you can handle sidestepping traps and stepping into homeownership with confidence.
Why Getting This Right Is Everything
A 2024 study from the National Association of Realtors found 42% of first-time buyers wished they’d borrowed less. No one wants to be stuck eating instant noodles just to keep the lights on in a house that’s too expensive. This guide is about finding a mortgage that fits your life—not one that owns you.
Step 1: The 28/36 Rule—Your Financial Guardrail
Lenders swear by the 28/36 rule, and it’s a solid starting point. Your monthly housing costs—mortgage, taxes, insurance—shouldn’t eat up more than 28% of your gross monthly income. Total debt payments, including student loans or car payments, shouldn’t exceed 36%.
Real-World Example: Say you make $5,500 a month:
- 28% = $1,540 for housing
- 36% = $1,980 for all debts combined
Quick Tip: Plug your numbers into a mortgage calculator to see what this means for you. There’s a good one linked below.
Step 2: Don’t Forget the Down Payment
Your down payment shrinks your loan amount. Aim for 20% to avoid private mortgage insurance (PMI), which can add $50–$200 a month. For a $350,000 home:
- 20% down = $70,000
- Loan amount = $280,000
Big Mistake to Avoid: Don’t empty your savings for a down payment. Keep a rainy-day fund—3–6 months of expenses—to stay secure.
Step 3: The Sneaky Costs You Can’t Ignore
A mortgage is just the start. Plan for:
- Property taxes: Check your area’s rates (they vary wildly)
- Homeowners insurance: Around $1,500/year on average
- Upkeep: Budget 1–2% of your home’s value annually
- HOA fees: Could be $200–$600/month if you’re in a community
True Story: My buddy Mike got hit with a $2,800 repair bill his first year because he didn’t budget for maintenance. Don’t be Mike.
Step 4: Crunch the Numbers (and Double-Check)
Mortgage calculators are your best friend. Enter your income, debts, down payment, and the current interest rate (around 6.7% for a 30-year fixed in June 2025, per Freddie Mac). You’ll get a clear picture of your monthly payment and loan size.

Step 5: Test Your Budget for Cracks
What if interest rates jump or you hit a financial rough patch? Run your budget through a worst-case scenario: try a 1% higher rate or 10% less income. If the numbers make you sweat, consider a cheaper home.
Personal Lesson: I got approved for a $450,000 loan but went with a $320,000 home. That choice gave me room to breathe, save, and even take a vacation. Trust me—peace of mind beats a fancy address.
