Buy to Let

Investing in property can be a powerful way to build long-term wealth, generate rental income and diversify your financial portfolio. A Buy-to-Let mortgage is the specialist financing product designed for landlords and property investors who want to purchase a rental property or refinance an existing investment.

At J Finance, we help both new and experienced property investors navigate the Buy-to-Let mortgage landscape with clarity, insight and tailored advice so you make confident decisions that align with your financial goals.

A Buy-to-Let mortgage is a loan used specifically for purchasing a property you intend to rent out rather than live in. These mortgages are structured around expected rental income and investment returns, rather than personal income alone.

Because the criteria differ from residential mortgages, Buy-to-Let lending requires specialist knowledge to secure the most appropriate product for your investment strategy.

Buy-to-Let mortgages are suitable for:

• First-time landlords, looking to buy their first rental property

• Accidental landlords, this is a term used for those who have inherited a property, or let out their previous residential home

• Experienced property investors expanding their portfolio

• Homeowners who want to move out but keep their existing property as a rental

• Portfolio landlords with multiple investment properties

• Landlords refinancing an existing Buy-to-Let mortgage

Whether you are buying one investment property or managing several, having the right mortgage structure is key to the long-term success of your investment.

Buy-to-Let lenders assess applications differently from residential mortgages. Rather than focusing solely on your personal income, lenders place significant emphasis on the rental income potential of the property.

Rental Income vs Personal Income

Lenders typically calculate how much rental income the property could generate — often requiring that the projected rent covers at least a set percentage of the mortgage payment (commonly around 125–145% of the monthly interest payment). This is known as the rental coverage ratio.

Your personal income and affordability still matter, but the property’s rental income plays a central role.

Interest-Only Structures

Most Buy-to-Let mortgages are offered on an interest-only basis, where you pay only the interest each month and repay the capital at the end of the term or by selling the property. This structure can improve cash flow but requires a plan to repay the capital amount.

Should you invest personally or via a limited company? We outline the pros and cons of each, and can introduce you to an accountant to discuss tax implications, helping you make an informed decision.

Larger Deposits

Buy-to-Let mortgages usually require a larger deposit compared with residential mortgages. Minimum deposits are often around 25% of the property value or more, depending on your profile and the lender.

Higher Rates and Fees

Because of the increased risk profile for lenders, Buy-to-Let mortgages may have higher interest rates and fees than standard residential products. Getting expert advice can help you find competitive terms that suit your circumstances.

Tax and Income Considerations

Rental income needs to be declared and may have tax implications that affect your net yield and overall return. Speaking with an accountant or financial adviser in conjunction with mortgage planning helps ensure you understand the full financial picture.

Buy-to-Let products can vary based on:

• Fixed-rate mortgages, giving certainty of payments for a set period

• Variable-rate mortgages, where the lender can move the rate up or down

• Tracker mortgages, which follow a base rate plus a set margin

• Interest-only vs repayment options depending on your exit strategy

Choosing the most appropriate structure depends on your investment strategy, risk tolerance and long-term plans. A tailored mortgage search ensures you get the best fit.
