Jumbo vs Conforming Loans
Jumbo loans historically carried rates 0.25-0.5% higher than conforming loans, but competitive markets sometimes offer jumbo rates at or below conforming rates. The trade-off is stricter qualification requirements—higher credit scores, larger down payments, and more documentation make jumbo loans less accessible than government-backed options.

What an Extra Payment Buys
Every dollar above the required $2,212 goes entirely to principal, which removes all the future interest that principal would have accrued:

|---|---|---|---|---|
| $50 | $2,262 | 28 yr 1 mo | $34,081 | 23 months |
| $100 | $2,312 | 26 yr 6 mo | $62,627 | 42 months |
| $250 | $2,462 | 22 yr 9 mo | $126,604 | 87 months |
| $500 | $2,712 | 18 yr 7 mo | $193,603 | 137 months |
Before Paying Extra
- Check for a prepayment penalty. Uncommon on mortgages now, still present on some auto
- Tell the servicer to apply it to principal. Many default to holding it as the next
- Compare against the alternative. Paying down 6.5% debt is a guaranteed
- Keep the emergency fund. Money paid into a loan is not retrievable without
