|---|---|---|---|
| 30 years | $4,172 | $841,793 | — |

What one percentage point of rate is worth here
On a $660,000 loan, going from 6.5% to 7.5% adds $443 a month — and $159,541 across the full term. At this size, a rate quote worth shopping for is worth more than most of the fees people negotiate instead.
The income a lender would look for
Lenders commonly cap housing costs at 28% of gross monthly income. On the full payment of $5,078 — principal, interest, tax, insurance — that implies roughly $217,624 a year before tax. It is a rule of thumb, not an underwriting decision: your other debts, credit score and deposit all move it. See what that salary looks like after tax.
