Navigating the world of mortgage loan types – fixed rate, adjustable rate, and more


Whether you’re planning to buy your first home, upsize, downsize, or invest in property, exploring the various types of mortgage loans is a critical step. Choosing the right type of mortgage loan can help save you thousands, while a wrong choice could lead you to financial constraints.

Main Forms of Mortgage Loans

1. Fixed-Rate Mortgages:
A fixed-rate mortgage loan is the most common type and is characterized by its stability over time. Regardless of market conditions, the interest rate on a fixed-rate mortgage loan stays the same throughout the loan’s duration. The principal and interest portion of your monthly payment does not change.

2. Adjustable-Rate Mortgages (ARMs):
Unlike fixed-rate mortgages, ARMs have fluctuating interest rates based on market conditions. They typically start with a low interest rate for a fixed period, usually 3, 5, 7, or 10 years. Afterward, the rate adjusts annually. However, there is a cap on how much the rate can increase, called a rate cap.

3. Interest-Only Mortgages:
Complex, but potentially beneficial under specific situations, interest-only mortgages allow you to pay solely the interest on your loan for a defined period. This approach significantly reduces your payments, but the outstanding balance remains unchanged. After the interest-only term, your required monthly payment will increase since you must repay the principal over a shorter period.

Detailed Overview

Fixed-Rate Mortgages:

Fixed-rate mortgages are incredibly predictable, making them appealing for those who prefer stability. They can range from 10-40 years, although 15 and 30 years are the most common terms. Your monthly payment is determined when you take the loan, helping you budget since your housing cost remains constant.

However, if you secure a loan when interest rates are high, you might be stuck with that rate unless you refinance. Moreover, fixed-rate mortgages generally have higher interest rates than adjustable-rate mortgages at first.

Adjustable-Rate Mortgages (ARMs):

The significant advantage of an ARM is the potential to save significantly on your mortgage payment. For the fixed initial period (with common formats like 5/1, 7/1, and 10/1), ARM rates are typically lower than fixed-rate mortgages, allowing you to afford more house initially.

However, the uncertainty and potential for increased payments is a downside. If the interest rate rises drastically, so can your monthly payment, potentially burdening you financially.

Interest-Only Mortgages:

For individuals who anticipate major financial fluctuations or have income tied to bonuses or commissions, interest-only mortgages can provide flexibility. With lower initial payments, they can buy a larger property or allocate money to other financial objectives.

The risk arises after the interest-only period. Payments can jump significantly, leading to ‘payment shock.’ Furthermore, since you haven’t reduced your principal in the interest-only period, you have less equity in your home.

Hybrid Types:

To increase flexibility, lenders often offer hybrid types of these primary mortgages. For instance, a Fixed Period ARM begins as a fixed-rate mortgage, then transitions into an ARM. There’s also a Two-Step Mortgage, featuring a constant rate for a specific period, then a different one for the remaining term.


When it comes to navigating the world of mortgage loans, it’s crucial to get acquainted with all options. Consider your financial situation, risk tolerance, and future projections. Consulting with a mortgage professional can further clarify your understanding, helping you make the most informed decision.
