Technically, there's no such thing as a "high" interest rate – it depends on what kind of loan you're applying for and how much you're willing to pay! For a personal loan, a high interest rate would be around 36%, while for a mortgage, this high of an interest rate would be more or less unheard of. Personal loans with interest rates around 6 to 10% are considered to have low interest rates, but for a mortgage, that would be astronomical (at least in 2022).
For a mortgage, a high interest rate would be in the 5 to 10% range.
