A borrower has a $400,000 mortgage with monthly payments of $2,200. After 5 years, they still owe $380,000. What type of mortgage structure is this most likely to be?
Correct Answer
B) Interest-only mortgage
The minimal reduction in principal ($20,000 over 5 years) despite regular payments suggests this is likely an interest-only mortgage. With a standard principal and interest mortgage, the balance would have reduced significantly more over 5 years.
Why This Is the Correct Answer
Option B is correct because the minimal principal reduction of only $20,000 over 5 years, despite monthly payments of $2,200, is characteristic of an interest-only mortgage. In this structure, borrowers pay only the interest portion during the initial period, with little to no principal reduction. The monthly payment amount suggests sufficient income to service a much larger principal reduction if it were a standard principal and interest loan, making interest-only the most logical explanation for this payment pattern.
Why the Other Options Are Wrong
Option A: Principal and interest table mortgage
A principal and interest table mortgage would show significant principal reduction over 5 years. With monthly payments of $2,200 on a $400,000 loan, the principal balance would typically reduce by $60,000-80,000 over 5 years, not just $20,000. This payment structure would result in much greater principal reduction than observed.
Option C: Reducing balance mortgage
A reducing balance mortgage is essentially the same as a principal and interest mortgage, where payments reduce the outstanding principal over time. This would result in substantial principal reduction over 5 years, not the minimal $20,000 reduction shown. The payment amount would achieve much greater principal reduction in a reducing balance structure.
Option D: Revolving credit mortgage
While revolving credit mortgages allow flexible payments, the consistent $2,200 monthly payment pattern and minimal principal reduction doesn't align with typical revolving credit usage. Revolving credit facilities usually show more variable payment patterns and, if payments were consistently this high, would typically result in greater principal reduction over 5 years.
Deep Analysis of This Finance Question
This question tests understanding of different mortgage structures by analyzing payment patterns and principal reduction. The key insight is recognizing that minimal principal reduction ($20,000 over 5 years) despite substantial monthly payments ($2,200) indicates an interest-only structure. In New Zealand's lending environment, interest-only mortgages are common investment property financing tools, allowing investors to maximize tax deductions while preserving cash flow. This connects to broader financial literacy concepts essential for real estate agents, including understanding how different mortgage structures affect clients' financial positions, cash flow, and investment strategies. The calculation reveals that most of the $2,200 monthly payment goes toward interest rather than principal reduction, which is characteristic of interest-only loans during their initial period.
Background Knowledge for Finance
Mortgage structures in New Zealand include various payment arrangements. Interest-only mortgages allow borrowers to pay only interest for an initial period (typically 1-5 years), with principal repayments deferred. Principal and interest (table) mortgages require regular payments covering both interest and principal reduction. Reducing balance mortgages calculate interest on the outstanding balance, with payments reducing principal over time. Revolving credit mortgages function like large overdrafts with flexible payment arrangements. Understanding these structures is crucial for real estate agents advising clients on financing options and interpreting financial capacity.
Memory Technique
Remember 'SLOW' - when you see Surprisingly Little Owing reduction over Wasted years, think Interest-Only. If someone pays substantial amounts but the principal barely budges, they're likely paying interest only, like treading water - lots of effort but staying in the same place.
When you see exam questions with large payments but minimal principal reduction over several years, immediately think 'SLOW' and consider interest-only mortgages. Look for the mismatch between payment size and principal reduction as your key indicator.
Exam Tip for Finance
Calculate the expected principal reduction: with $2,200 monthly payments, a standard P&I mortgage would reduce principal by $60,000+ over 5 years. When actual reduction is much less, choose interest-only.
Real World Application in Finance
An investor purchases a rental property with a $400,000 interest-only mortgage at 6.5% interest. Monthly payments of $2,167 cover interest only, maximizing tax deductions and preserving cash flow for property improvements or additional investments. After 5 years, they still owe the full $400,000 principal but have benefited from rental income and potential capital gains. As a real estate agent, understanding this helps explain to investor clients why their mortgage balance hasn't decreased despite years of payments.
Common Mistakes to Avoid on Finance Questions
- •Assuming all mortgages reduce principal equally over time
- •Not calculating expected principal reduction for comparison
- •Confusing revolving credit flexibility with interest-only structures
