Real Estate Trisha Cook July 1, 2025
For decades, buyers have been told to follow one simple rule:
Don’t spend more than 30% of your income on housing.
That is the gold standard. The budget benchmark. The line in the sand between “affordable” and “overextended.”
But in 2025, that line no longer seems attainable.
According to a Realtor.com® Affordability Report, the typical U.S. household would need to spend 44.6% of their income to buy a median-priced home today. And in cities like Los Angeles, that number jumps to over 100%.
So if you’re staring down home prices, crunching the numbers, and wondering why the math doesn’t add up anymore, you’re not alone. The old rulebook doesn’t work in this market.
But that doesn’t mean you’re stuck. It just means it’s time to budget differently.
The 30% rule was never meant to be a law. It came from a 1969 housing policy called the Brooke Amendment, with capped public housing rent at 25% of a tenant’s income. In the early 1980s, that cap increased to 30%, and eventually became a go-to formula for financial advisors, mortgage lenders, and online calculators.
And for a while, it worked.
It helped buyers avoid overspending and left room for things like savings, emergencies, and daily life.
But here’s what it missed:
It doesn’t account for regional cost differences (a $1,200 mortgage hits differently in Savannah vs. San Francisco).
It ignores existing debt, child care, or medical costs.
It assumes stable interest rates and steady home prices.
In today’s market, sticking to 30% can feel impossible. So instead of trying to squeeze your dream into an outdated formula, here’s a better approach.
Forget percentages for a moment. Ask yourself:
How much are you comfortable spending each month on housing, while still living the life you want?
Look at your:
Current rent or mortgage
Other fixed expenses (car, insurance, groceries)
Debt and loan payments
Savings goals and emergency fund
Travel, hobbies, or childcare
The right number doesn’t have to be 30% of your income, but it does need to keep you financially stable, secure, and sane.
When you see a home listed at $450,000, that’s not your monthly payment.
Here’s what you need to factor in:
Mortgage principal and interest
Property taxes
Homeowners insurance
PMI (if putting down less than 20%)
HOA fees (if applicable)
Maintenance and utilities
Online estimates can get you in the ballpark, but a good Realtor or Lender can break it down line by line, even before you fall in love with a house. Choose a local lender for closer estimates on taxes, HOA, etc
If your housing costs are hovering above 30%, it doesn’t automatically mean you’re in trouble, especially if you don't have a lot of debt outside of your monthly housing payments.
But if you’re creeping up toward 50% and also juggling credit card debt, student loans, or a variable income, that’s a red flag, and means you should pause and re-evaluate.
Affordability isn’t just about price. It’s about opportunity.
Here are a few levers that can shift the numbers in your favor:
Broaden your search area. A 15-minute drive can mean a 15% price drop.
Look at new construction. Builders may offer incentives that reduce monthly costs.
Ask about rate buydowns or creative financing. Sellers are becoming more motivated than in the past couple of years.
Focus on what you can comfortably afford now. Your first (or next) home doesn’t have to be your forever home.
The 30% rule might be outdated, but the goal behind it isn’t.
You still want a home you can comfortably afford. One that fits your lifestyle, not just your loan approval. And the good news? That’s still possible in 2025.
You just need a more personal approach.
