When most people think of mortgages, they picture the traditional route: fixed rates, variable rates, and straightforward affordability checks. But the world of mortgages is far more diverse. Depending on your financial situation, goals, or values, there are specialised mortgage products that could save you money, increase your borrowing potential, or solve unique challenges.
In this guide, we’ll explore 10 niche mortgage types that go beyond the basics. Some might even help you pay zero interest!
1. Offset Mortgages
An offset mortgage allows you to use your savings to reduce the interest you pay on your mortgage. Here’s how it works:
Your savings balance is “offset” against your mortgage balance, and you only pay interest on the difference. For example:
• Mortgage balance: £200,000
• Savings: £50,000
• Interest charged: Only on £150,000.
If your savings match or exceed your mortgage balance (e.g., £200,000 in both accounts), you’d pay zero interest!
Why choose this?
• Your savings remain accessible, so you can dip into them if needed.
• You can save a fortune on interest while still working towards repaying the loan.
• Ideal for anyone with significant savings or those who value liquidity.
2. Contractor Mortgages
If you’re self-employed or a contractor, traditional lenders often struggle to assess your income, which can lead to rejection or limited borrowing options. Contractor mortgages, however, take a different approach:
• Lenders calculate your income based on your daily or hourly rate and project it across a year (e.g., £300/day for 5 days/week = £78,000 annual income).
• No need to rely on payslips or multiple years of accounts.
Example
Maria, a freelance graphic designer, earns £400/day on average but has only been contracting for a year. Traditional lenders required two years of accounts, but a contractor mortgage allowed her to borrow based on her projected annual income of £96,000.
3. Mortgages Based on Company Reserves
For directors of limited companies, most lenders only consider your personal income (e.g., salary and dividends) when assessing affordability. But what if you retain profits in the business to reduce tax?
Specialist mortgages allow lenders to assess your company’s retained profits alongside your personal income, significantly increasing your borrowing power.
Why choose this?
• Maximise your affordability without withdrawing unnecessary funds from your business.
• Great for directors who prioritise tax efficiency.
Example
Fola runs a small tech company and pays himself a modest salary of £30,000. His company has £200,000 in retained profits. Using a mortgage based on company reserves, Fola was approved for a £500,000 mortgage.
4. Joint Borrower, Sole Proprietor Mortgages
Parents often want to help their children buy a home but are wary of triggering additional stamp duty charges on second properties. A joint borrower, sole proprietor mortgage allows parents to co-sign a loan to boost affordability without being listed as property owners.
Why choose this?
• Avoid the 3% stamp duty surcharge for second homes.
• Help your child get on the property ladder while keeping the home in their name.
Example
Emma and her parents used this mortgage to secure a £300,000 property. By keeping her parents off the title deeds, they avoided an £8,000 stamp duty surcharge.
5. Flexible Mortgages
Life isn’t always predictable, and flexible mortgages are designed to adapt to your circumstances. They allow you to:
• Overpay when you have extra cash.
• Underpay during tight months.
• Take payment holidays if needed.
Why choose this?
• Perfect for those with fluctuating incomes, like freelancers or seasonal workers.
• Offers peace of mind during life’s ups and downs.
6. Guarantor Mortgages
If you’re struggling to get approved due to a low income or limited deposit, a guarantor mortgage could be the solution. A family member or friend acts as a guarantor by offering their savings or property equity as security.
Why choose this?
• Great for first-time buyers or those with a poor credit history.
• Opens the door to home ownership when other routes aren’t an option.
7. Green Mortgages
Eco-conscious buyers, this one’s for you. Green mortgages incentivise energy-efficient homes or upgrades by offering:
• Lower interest rates.
• Cashback rewards for improving your property’s energy rating.
Why choose this?
• Save money on your mortgage and energy bills.
• Contribute to a more sustainable future.
8. Professional Mortgages
Certain professions, like doctors, lawyers, or accountants, are considered lower-risk borrowers by some lenders. Professional mortgages account for your earning potential rather than just your current income.
Why choose this?
• Borrow more at the start of your career.
• Benefit from exclusive deals tailored to professionals.
Example
Sarah, a junior doctor earning £35,000, was approved for a £300,000 mortgage because her career trajectory suggested significant future income growth.
9. Buy-for-Uni Mortgages
Students can become homeowners while studying! With a buy-for-uni mortgage, students purchase a property and rent out spare rooms to cover the mortgage payments.
Why choose this?
• Build equity during university instead of just paying rent.
• Gain early experience in property ownership and management.
Example
Tom, a university student, bought a £200,000 flat with a buy-for-uni mortgage. Renting two spare rooms covered most of his mortgage payments, leaving him with a valuable asset after graduation.
10. Halal Mortgages (Islamic Home Financing)
For those following Sharia law, paying or earning interest is prohibited. Halal mortgages avoid interest by using a different structure:
• The lender buys the property with you.
• You pay rent plus an ownership share over time until you fully own the property.
Why choose this?
• Ethical and compliant with Islamic principles.
• Increasingly available in the UK through specialist lenders.
The Bottom Line
Choosing the right mortgage isn’t just about finding the lowest interest rate—it’s about aligning the product with your financial goals and personal circumstances. These niche mortgage options open up a world of possibilities, whether you’re self-employed, a student, or looking to save on interest.
