    • Exemple Résolu

    A $900,000 home with 20% down. Jumbo rate 7.25%, conforming rate 6.75%, 30-year term.

    1. Down payment: $900,000 x 20% = $180,000
    2. Loan amount: $900,000 - $180,000 = $720,000
    3. Amount over conforming limit: $720,000 - $766,550 = -$46,550 (under limit in this case)
    4. Jumbo payment at 7.25%: $720,000 over 360 months = $4,912.19
    5. Conforming comparison at 6.75%: $766,550 over 360 months = $4,971.75
    6. Jumbo total interest: $4,912.19 x 360 - $720,000 = $1,048,388
