|---|---|---|---|
| 30 years | $3,919 | $790,777 | — |

What one percentage point of rate is worth here
On a $620,000 loan, going from 6.5% to 7.5% adds $416 a month — and $149,872 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 $4,779 — principal, interest, tax, insurance — that implies roughly $204,825 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.
