Pre-approval tells you what a lender will allow. This is how to figure out what you should actually spend.
The maximum loan a lender approves and the payment you'll be comfortable with for the next decade are two different numbers. Underwriting looks at documented income and debts. It does not know about your daycare bill, your travel habits, or the fact that you'd like to keep investing.
Start from your take-home pay rather than gross income. A payment that consumes more than about 28% of gross — or roughly a third of net — starts crowding out everything else.
Count the whole payment
The number that matters is PITI plus any HOA: principal, interest, property taxes, homeowners insurance, mortgage insurance if applicable, and dues. Taxes and insurance alone can add several hundred dollars a month over the principal-and-interest quote you see advertised.
- Principal and interest — the loan itself
- Property taxes — varies enormously by county
- Homeowners insurance — rising fast in many states
- Mortgage insurance — applies under 20% equity on most non-VA loans
- HOA or condo dues — and check the reserve study
Budget for the first year of ownership
New owners consistently underestimate move-in costs: window coverings, a mower, a plumber, the appliance that dies in month three. Keep three to six months of full housing costs in reserve after closing. That cushion is what turns a house from a stressor into an asset.
