Answer: 1. the rate on the variable loan is open to fluctuations.
A variable interest rate loan is a loan with an interest rate that varies as market interest rates change. As a result, payments can change too. On the other hand, fixed interest rate loans are those in which the interest rate charged in the loan remains fixed for the entire term of the loan, no matter what happens with market interest rates.
The disadvantage that a variable loan has when compared to a fixed rate loan is that the variable loan is open to fluctuations in market interest rates. This uncertainty means that it is possible for your payments to increase in the future.
