First, Determine How You'll Pay Interest

Before you get started learning about loan types, you might want to take some time to read up on interest rate options, because, yes, you've even got choices for those. Here are the three most common interest rate options in modern mortgages.


  • Interest rate remains the same throughout the duration of the loan
  • Payments remain the same throughout the duration of the loan
  • Very predictable monthly payments


  • Interest rates may start out lower for a set period, then flux to match current interest rates
  • Rates may increase or decrease depending on the economy
  • Monthly payments are unpredictable and may increase or decrease


  • Also called 5/25s or 7/23s
  • Offers an initial fixed interest rate for the first 5 to 7 years, then converts to current market rates
  • Can be convertible (buyer can choose another fixed-rate loan) or nonconvertible (automatically switches to adjustable)

Next, Choose Your Loan

Now that you've got an idea of the interest rates that might work best for you, it's time to take a look at some of your loan options.
