Interest rate and amortization
| Rate / term | Monthly payment |
|---|---|
| 6.0% / 30 yr | $599.55 |
| 7.0% / 30 yr | $665.30 |
| 8.0% / 30 yr | $733.76 |
| 7.0% / 15 yr | $898.83 |
A one-point rate change moves the payment by roughly $65–70 per $100,000 on a 30-year loan. Shorter amortization builds equity faster but raises the payment and lowers cash flow.
For current rate context, the Federal Reserve Bank of St. Louis publishes the weekly Freddie Mac 30-year average; investment-property quotes typically differ from that owner-occupied benchmark.
