Every buyer asks me some version of how much house can you afford in the first five minutes we talk, and almost every online calculator gives them the wrong answer. Not wrong in a dishonest way, just wrong in the way that matters: it tells you what a bank will lend you, not what actually makes sense for your life.
Here’s how I’d rather you think about it.
Start With Your Monthly Number, Not the Purchase Price
Two people can afford the exact same purchase price and have completely different monthly realities, because property taxes vary so much town to town out here. A $450,000 home in one town can carry a noticeably different monthly tax bill than the same price in another. That’s not a small detail. Over a 30-year mortgage, it can be the difference of tens of thousands of dollars.
So before you fall in love with a number on Zillow, figure out what monthly payment you’re actually comfortable with, taxes and insurance included, not just principal and interest.
Pre-Approved Is Not the Same As “Should”
A lender will often approve you for more than you should actually spend. That’s not them being predatory, it’s just how the math works on their end. Pre-approval tells you the ceiling. It doesn’t tell you where you’ll actually be comfortable living.
I always ask clients to sit with their pre-approval number for a few days and ask themselves honestly: if this were my monthly payment starting next month, would I still be able to travel, save, and not feel stretched? If the answer is no, we look at a lower range, even if the bank says yes to more.
Don’t Forget the Cost of Moving In
Closing costs, a moving truck, that first list of things every new house needs (a lawn mower, curtains, maybe a washer that isn’t 20 years old), it adds up fast. I tell every buyer to keep a cushion beyond the down payment for the first few months, because the house doesn’t stop costing money the day you get the keys.
The Real Question Isn’t How Much House Can You Afford
It’s “what am I actually trying to build here.” A starter home you’ll outgrow in three years calls for a different budget conversation than a forever home. Once we’re clear on that, the affordability number gets a lot easier to pin down.
If you want to actually run your specific numbers, not a generic calculator’s, that’s exactly what a free coaching session is for. We’ll go through your situation directly, whether you’re looking in Wheaton, Glen Ellyn, or anywhere else in the western suburbs, and figure out a real number together.
