Approved for $600k—sleeping fine?
Underwriting can clear a payment that fits spreadsheets while your life runs on daycare, elder care, gas, and the furnace that dies in February. The lender’s job is bounded risk on paper; your job is solvency through messy months. Those are related—not identical.
Why “afford” is two different questions
Capacity to repay (what lenders model) is not the same as margin to thrive. A debt-to-income ratio can look fine while a thin emergency fund and a variable-income household mean one slow quarter away from stress. Debt math is sterile; life is not.
What lenders actually weigh
- Debt-to-income (DTI): required monthly debts vs gross income—caps vary by program; you can choose stricter.
- Down payment and reserves: more cash up front often buys rate stability and post-close breathing room.
- Credit and loan type: they change the rate you qualify for—which changes everything downstream.
From thumb rules to your numbers
Heuristics like 28/36 or “2.5× income” are cartoons. Real affordability needs PITI, HOA, utilities, maintenance (often 1% of value per year as a blunt benchmark), and savings goals—then stress the rate up 1–2% to see if you still want the house.
Try it yourself
Bank model vs household reality
Lender view: documented income, DTI, credit, assets Your view: maintenance, mobility, job risk, kids, savings goals Goal: payment + life costs + reserves — not payment alone
Concrete next moves
- Model payment at +2% rate shock before you fall in love with a listing.
- Keep emergency cash outside home equity—equity is not spendable in a crisis at will.
- Compare rent vs buy on a horizon you can commit to; short horizons often favor flexibility.
Expensive ones
- Borrowing the max because “the bank said yes.”
- Ignoring PMI, HOA, and utilities when mentally budgeting “mortgage only.”
- Assuming you will refinance later—rates and home equity owe you nothing.

FAQ
- Should I borrow the maximum I am approved for?
Only if that max still leaves savings, insurance against job loss, and room for real costs. Approval is not a recommendation.
- What DTI should I aim for personally?
Lower than the lender’s ceiling if you want cushion—exact target depends on income stability and fixed obligations.
- Is a bigger down payment always better?
Often for rate and PMI, but not if it strips your emergency fund—liquidity has value.
