Choose a mortgage when

You need a large loan, have collateral, and want the lowest sustainable long-term borrowing cost.

Consider a personal loan when

You need funds quickly, but can still keep the monthly payment comfortably within your income.

Avoid using credit cards as long-term debt when

You expect to carry the balance for many months, because revolving APR can become the most expensive option.
