| Item | Detail |
|---|---|

| Loan amount | Price × (1 − down %) |
| Payment | Amortizing PMT |
Lenders may use different overlays even when under the published limit.
How the estimate is built
Loan = price − down. Payment = loan.pmt(loan, rate, term months). Jumbo flag = loan > threshold.
Example scenario
$1.2M home, 20% down → $960k loan. If threshold is $806,500, the loan is jumbo; P&I follows your rate and term.
