Answer:
Fixed-rate
Explanation:
Fixed-rate loans and mortages are those that have a specific interest rate, and a specific payment that will not ever change over the duration of the loan because both are fixed. In other words, a fixed-rate loan is simply a annuity payment over a particular period of time.
For first-time buyers this is the easiest option because it is simple, it can be easily projected over time, and helps with financial planning.
