🏠 How Much House Can You Afford in 2026?
Buying a home is the biggest financial decision most Americans ever make. But here's the truth: most buyers don't know their real budget until a lender tells them — and by then, they've already fallen in love with a house they can't afford.
This guide breaks down exactly how to calculate your home budget before you shop. You'll learn the 28/36 rule that US lenders use, the down payment math that determines your monthly payment, and the hidden costs most buyers forget. By the end, you'll know your number — down to the dollar.
Most US lenders approve you for a home that costs 3–4 times your annual gross income. If you earn $85,000/year, your max home price is typically $255,000–$340,000 — but your actual budget depends on debts, down payment, and credit score. Use the House Affordability Calculator for your exact number.
📊 The 28/36 Rule (What Lenders Use)
The 28/36 rule is the standard US mortgage approval guideline. Here's how it works:
Your total housing payment (mortgage + taxes + insurance + HOA + PMI) should stay under 28% of gross monthly income.
All monthly debt payments combined (housing + cars + student loans + credit cards) should stay under 36% of gross monthly income.
Real-World Example: $85,000/year salary
| Gross monthly income | $7,083 |
| 28% max housing payment | $1,983 |
| Existing monthly debts (car, card) | − $550 |
| Property tax + insurance + HOA estimate | − $550 |
| Left for Principal & Interest | $883/mo |
| → Max Home Price (at 6.75% rate, 20% down) | ~$265,000 |
Run your own numbers with the House Affordability Calculator — it applies the 28/36 rule automatically and shows your max home price.
💵 How Down Payment Changes Everything
If you put less than 20% down, you'll pay PMI (Private Mortgage Insurance) — typically 0.5–1.5% of the loan amount per year. On a $300,000 loan, that's $1,500–$4,500 per year on top of your mortgage. Putting 20% down avoids PMI entirely.
| Down Payment | Monthly Savings | PMI? |
|---|---|---|
| 5% | Baseline | Yes (~$150/mo) |
| 10% | − $120/mo | Yes (~$100/mo) |
| 15% | − $210/mo | Yes (~$50/mo) |
| 20% | − $260/mo | No PMI ✓ |
| 25%+ | − $300/mo | Best rates ✓ |
🧾 Costs Most Buyers Forget
- Closing costs: 2–5% of purchase price ($8K–$20K on a $400K home)
- Property tax: 0.5–2.5% annually, varies wildly by state
- Home insurance: $1,200–$2,400 per year on average
- Maintenance: Budget 1% of home value per year for repairs
- HOA fees: $0–$800/month depending on community
- Utilities: Often $200–$400/month for a single-family home
Just because a lender approves you for $600K doesn't mean you should spend $600K. Leave 10–15% headroom for emergencies, repairs, and life changes. House-poor is a real thing.
