A ‘term’ is the length of time that borrowers spread their loan repayments over. Choosing the term length of a mortgage is a crucial decision that can have a significant impact on a borrower’s financial situation. While long-term and short-term mortgages both have their advantages and drawbacks, determining which option is better depends on various factors such as financial goals, affordability and personal circumstances. 

This comprehensive guide aims to explore the pros and cons of long-term and short-term mortgages, helping borrowers make an informed decision based on their unique needs.



How Do Long-Term Mortgages Work?


Long-term mortgages typically have a term length of 30 years, although 25 year and 40 year terms are also available. In fact according to UK Finance, there has been a dramatic increase of borrowers choosing 40 year mortgages over the past 2 years.

Here are the key advantages and disadvantages of choosing a long-term mortgage:

Advantages  Disadvantages
Lower Monthly Payments – A key benefit of long-term mortgages is the lower monthly payment. By spreading the loan repayment over a longer period, borrowers can enjoy more affordable monthly installments, making homeownership more accessible. Higher Interest Costs – The longer repayment period of a long-term mortgage translates into higher total interest costs over the life of the loan. Borrowers end up paying more in interest compared to shorter-term mortgages, reducing the overall return on their investment.
Improved Cash Flow and Budgeting – Lower monthly payments free up cash flow and provide borrowers with more financial flexibility. This can be especially beneficial for individuals with other financial obligations or those who prefer to allocate their money towards investments, savings or other expenses. Slower Equity Building – While long-term mortgages enable the accumulation of equity, the process is slower due to the extended repayment period. Borrowers may have to wait longer to fully own their homes and enjoy the benefits of homeownership, such as potential rental income or the ability to leverage equity for other purposes.
Stability and Predictability – Long-term mortgages offer stability and predictability in terms of monthly payments. Since the interest rate is usually fixed for the entire term, borrowers can accurately budget and plan their finances without worrying about fluctuations in interest rates.
Accumulation of Equity – Over time, borrowers gradually build equity in their homes through regular mortgage payments and potential property value appreciation. Long-term mortgages allow borrowers to accumulate equity at a slower but steadier pace, which can be advantageous for long-term homeownership goals.


How Do Short-Term Mortgages Work?


Short-term mortgages, often referred to as “term loans” or “fixed-rate loans,” typically have term lengths of 15, 10 or even 5 years. Consider the following advantages and disadvantages of choosing a short-term mortgage:

Advantages Disadvantages
Lower Total Interest Costs – Short-term mortgages generally come with lower interest rates compared to long-term mortgages. This translates into substantial savings in total interest costs over the life of the loan, allowing borrowers to build equity faster. Potential Affordability Challenges – Short-term mortgages come with higher monthly payments due to the compressed repayment period. This can pose affordability challenges for borrowers with limited income or higher debt-to-income ratios.
Faster Equity Building – With higher monthly payments and a shorter repayment period, borrowers build equity at an accelerated pace. This can be advantageous for those seeking to fully own their homes quickly or leverage equity for other investment opportunities. Limited Financial Flexibility – Higher monthly payments associated with short-term mortgages leave borrowers with less discretionary income for other financial priorities. It is important to carefully consider cash flow requirements and the ability to comfortably manage higher monthly payments.
Reduced Debt Burden – Paying off the mortgage sooner means borrowers become debt-free faster, providing a sense of financial freedom and security. It can also open up opportunities for other financial goals, such as saving for retirement or funding education. Vulnerability to Interest Rate Increases – Short-term mortgages often come with adjustable interest rates, which means the interest rate may change after an initial fixed-rate period. If interest rates rise significantly, borrowers could face higher monthly payments, potentially straining their budget.


What Factors Are There To Consider When Deciding Between A Long-Term Or Short-Term Mortgage?


When deciding between a long-term or short-term mortgage, borrowers should consider the following factors:


Financial Goals

Consider your short-term and long-term financial goals. If building equity rapidly and owning your home outright is a priority, a short-term mortgage may be more suitable. If cash flow and budgeting flexibility are important, a long-term mortgage may be the better choice.



Assess your current financial situation, including income, debt obligations and overall affordability. Short-term mortgages require higher monthly payments, so ensure you can comfortably manage the increased financial responsibility.


Interest Rate Environment

Consider prevailing interest rates and forecasts. If interest rates are low or expected to rise significantly, a long-term mortgage with a fixed interest rate can provide stability and protection against future rate hikes.


Time Horizon

Evaluate your plans for the property. If you anticipate selling or refinancing the home within a few years, a short-term mortgage can be a strategic choice. For those planning to stay in the home for an extended period, a long-term mortgage may align better with their objectives.


Financial Discipline

Consider your financial discipline and ability to save. Short-term mortgages require higher monthly payments but can accelerate equity building. If you have the discipline to save and invest the difference between short-term and long-term mortgage payments, you may achieve similar results with a long-term mortgage while maintaining greater flexibility.


Risk Tolerance

Evaluate your risk tolerance and comfort level with debt. Short-term mortgages involve paying off the loan faster, reducing overall interest costs but increasing monthly payment obligations. Assess your risk tolerance and determine what level of financial responsibility aligns with your comfort zone.




Deciding between a long-term or short-term mortgage depends on various factors such as financial goals, affordability and personal circumstances. Long-term mortgages offer lower monthly payments, improved cash flow and stability but come with higher overall interest costs and slower equity building. Short-term mortgages facilitate faster equity accumulation, lower total interest costs, and faster debt repayment but may pose affordability challenges and limit financial flexibility. 

Consider your financial goals, affordability, prevailing interest rates, time horizon, financial discipline and risk tolerance when making this important decision. Remember, what may be suitable for one borrower may not be the best choice for another. For instance, some first time buyers may prefer long-term mortgages, but a pensioner may prefer a shorter-term mortgage. Consulting with mortgage professionals and financial advisors can provide valuable guidance in selecting the mortgage term that aligns with your specific needs and objectives.
