Typical market rates are often in a mid-single-digit range, but they move over time and vary by deposit size, product type, and credit profile.

Repayment vs interest-only: repayment reduces what you owe each month; interest-only keeps the full balance outstanding, so you need a separate plan to clear the capital at term end.

Mortgage Balance Over Time

The curve is steepest early on because more of each payment goes to interest at the start. As the balance falls, interest costs drop and a bigger share goes to capital, so the loan clears faster later in the term.
