A $450,000 home: why the mortgage payment is not the budget
Assume a 20% down payment, a $360,000 fixed-rate loan at an illustrative 6.5% annual interest rate, and 360 monthly payments. The rate is a teaching assumption, not a current offer. Taxes and insurance below are invented inputs, not estimates for a location.
Example breakdown in U.S. dollars
Item
Amount or result
Principal and interest
$2,275.44
Property tax: $5,400 / 12
$450.00
Insurance: $2,400 / 12
$200.00
Utilities
$300.00
Maintenance reserve
$375.00
Monthly housing budget
$3,600.44
How to reproduce the calculation
Monthly principal and interest = L × r / (1 − (1 + r)^−n), where L = 360,000, r = 0.065 / 12 and n = 360. Add $1,325 of other monthly inputs. If annual tax rises to $6,600 and annual insurance to $3,600, the budget rises by $200 to $3,800.44. Those higher inputs are a stress test, not a forecast.
What changes in your decision
A buyer with a $3,700 monthly limit fits the initial housing budget but exceeds it in the stress test. Before proceeding, obtain an address-specific insurance quote and check the post-purchase tax treatment. Add HOA, mortgage insurance, separate hazard cover and transport if applicable; this example assumes none. A maintenance reserve is savings for future work, not a guaranteed repair bill.
For the same $450,000 purchase, assume a $90,000 down payment, $13,500 of closing charges including prepaids, a $9,000 deposit already paid and credited, and a permitted $3,000 seller credit. Assume no other adjustments or financed closing costs. These are hypothetical amounts.
Example breakdown in U.S. dollars
Item
Amount or result
Down payment
$90,000
Closing charges including prepaids
+ $13,500
Deposit already paid and credited
− $9,000
Seller credit applied to eligible costs
− $3,000
Remaining funds due at closing
$91,500
How to reproduce the calculation
Remaining closing funds = $90,000 + $13,500 − $9,000 − $3,000 = $91,500. Total buyer transaction cash, including the deposit already paid, is $100,500. Keeping a separate $10,000 reserve requires $110,500 across transaction cash and retained savings. The reserve is not a charge payable to the closing agent.
What changes in your decision
Subtract only deposits actually credited on the closing statement. Do not subtract a seller credit again if your fee total already includes it. Verify the credit is permitted and usable with the lender and closing agent. Compare the Loan Estimate with the final Closing Disclosure; prorations and other adjustments can change the amount. Confirm payment instructions through a trusted phone number before transferring funds.
Discount points: a lower rate can cost more over a short stay
Compare two hypothetical $360,000 fixed-rate loans with the same 30-year term and all other fees identical. Offer A has a 6.5% rate and no points. Offer B has a 6.25% rate and one point costing $3,600 paid upfront, not financed. Neither rate is a live quote.
Example breakdown in U.S. dollars
Item
Amount or result
Offer A monthly principal and interest
$2,275.44
Offer B monthly principal and interest
$2,216.58
Monthly payment saving
$58.86
Extra upfront cost
$3,600
Simple payment break-even
61.2 months / meses
How to reproduce the calculation
Simple break-even = $3,600 / approximately $58.86 = 61.2 months. After 36 payments, payment savings are approximately $2,119; after 84 payments, approximately $4,944. These compare payment cash flows only. Different remaining principal balances, the time value of money, taxes and opportunity cost are excluded; this is not a total-cost comparison.
What changes in your decision
For a possible sale or refinance after three years, the lower payment has not recovered the upfront points through payment savings alone. Ask for matching Loan Estimates, APR and the five-year comparison, then compare the actual intended holding period and remaining balances. A lender credit reverses the trade-off: a higher rate can reduce cash needed upfront. Choose using the written offers, not the advertised rate alone.
