The Payment Isn't the Cost
What your lender doesn't tell you about the real cost of homeownership
Your mortgage payment is just the beginning. Most buyers focus on getting approved and locking in a rate — and then they're blindsided by everything that comes after closing. Here's the full picture.
When a lender tells you that you're approved for a $2,200/month payment, that number is just the principal and interest on your loan. It doesn't include property taxes, homeowner's insurance, HOA fees, or PMI if you put less than 20% down. Add those in and you're often looking at $500–$900 more per month than the payment you were quoted.
Then there's maintenance. The general rule of thumb is to budget 1–2% of your home's value per year for upkeep. On a $350,000 home, that's $3,500–$7,000 annually — or $290–$580 per month — just to keep the house in good shape. HVAC systems, roofs, water heaters, appliances: they all have a lifespan, and they all eventually need replacing.
There's also opportunity cost. The down payment you put into a home is money that isn't in the market. That's not an argument against buying — homeownership builds equity and provides stability — but it's a real cost that rarely shows up in the affordability conversation.
None of this means you shouldn't buy. It means you should buy with eyes open. Before you fall in love with a payment, run the full number. I help every buyer I work with build a realistic monthly cost picture before we ever write an offer.
