FAQs
A buy-to-let remortgage allows you to switch your existing mortgage on a rental property to a new deal, either with your current lender or a new one.
As a landlord, finding a better mortgage deal is worth considering, as lowering your mortgage costs can boost your profits. Remortgaging your buy-to-let property could help you save money or free up equity to invest in expanding your property portfolio or renovating your current property.
If you have sufficient equity built up, remortgaging could also allow you to release funds to use as a deposit for your next buy-to-let property or even buy it outright. Additionally, if you decide to rent out a property you currently live in, you’ll typically need to switch from a residential mortgage to a buy-to-let mortgage.
It’s important to plan for times when your property may be unoccupied, as you’ll still need to make your mortgage payments. Buy-to-let remortgage rates are often higher than standard residential rates, so having a contingency fund is essential.
What is a Buy to Let Mortgage and How Does it Work?
A Buy to Let (BTL) mortgage is a type of loan designed for those looking to purchase a property to rent out. Unlike residential mortgages, BTL mortgages are usually interest-only, meaning you only pay the interest each month, while the capital (the amount borrowed) remains outstanding. At the end of the mortgage term, you’ll need to repay the full loan amount, which can typically be done by selling the property or refinancing.
These mortgages are often taken out by landlords and property investors, and lenders assess applications based on the expected rental income rather than just personal income. However, affordability checks and minimum income requirements still apply.
What Types of Buy to Let Mortgages Are Available?
BTL mortgages come in different types, and choosing the right one depends on your financial situation and investment strategy. These include:
- Fixed Rate Mortgages – The interest rate remains the same for a set period, providing certainty over repayments.
- Tracker Mortgages – The interest rate follows the Bank of England base rate, meaning payments can fluctuate.
- Discount Rate Mortgages – A variable-rate mortgage offering a discount on the lender’s standard variable rate (SVR) for a set period.
- Capped Rate Mortgages – A variable mortgage where the interest rate won’t go above a certain limit.
- Offset Mortgages – Your savings are linked to your mortgage, reducing the interest you pay.
As experienced Buy to Let mortgage brokers, we can help you navigate the options and find the most suitable deal for your circumstances.
How Much Can I Borrow?
Lenders determine how much you can borrow based on your expected rental income rather than just your personal salary. They typically require rental income to be at least 125% to 145% of the monthly mortgage payment to ensure you can cover costs, even if interest rates rise. Some lenders may also take your personal income into account, particularly if you’re a first-time landlord.
What Are the Costs Involved with a Buy to Let Mortgage?
Aside from your deposit and monthly repayments, there are other costs to consider when investing in rental property. These may include:
- Mortgage arrangement fees – Some lenders charge upfront fees for setting up the mortgage.
- Valuation fees – The lender will need to assess the property’s value before approving your loan.
- Legal fees – You’ll need a solicitor or conveyancer to handle the legal aspects of the purchase.
- Stamp Duty – Buy to Let properties incur higher Stamp Duty charges than residential homes.
- Maintenance and repairs – Keeping your property in good condition ensures it remains attractive to tenants.
- Letting agent fees – If you use an agent to manage your property, they will take a percentage of the rent.
We help landlords budget for these costs and ensure their investment is financially viable.
What Happens at the End of an Interest-Only Buy to Let Mortgage?
Most Buy to Let mortgages are interest-only, meaning that at the end of the term, you still owe the full amount borrowed. It’s essential to have a repayment strategy in place to settle the debt when the time comes. Common repayment strategies include:
- Selling the property – Many landlords plan to sell the property and use the proceeds to pay off the loan.
- Remortgaging – Some investors choose to refinance onto a new mortgage to extend the loan term.
- Using savings or investments – If you have other assets, you may choose to repay the mortgage using personal funds.
Having a clear exit plan is crucial to avoid financial strain when the mortgage term ends. We can help you assess your options and find the best long-term strategy for your investment.
What Does a Solicitor or Conveyancer Do?
A solicitor or conveyancer plays a crucial role in transferring legal ownership of the property and ensuring everything is in order. They will:
- Review the property contract and ensure all legal requirements are met.
- Carry out searches to check for planning issues, flood risks, or other potential problems.
- Confirm rental restrictions or leasehold conditions that may affect your ability to rent out the property.
- Arrange the exchange of contracts and set a completion date.
- Handle the payment of Stamp Duty (which is higher for Buy to Let properties).
- Register your ownership with the Land Registry.

Do I Need a Special Buy to Let Mortgage If Purchasing Through a Limited Company?
If you’re buying a rental property through a Limited Company, you’ll need a specialist Buy to Let mortgage. Many landlords choose this route for tax efficiency, particularly higher-rate taxpayers, but it’s important to seek advice from a tax adviser before making any decisions.
Limited Company Buy to Let mortgages often have higher interest rates, compared to personal Buy to Let mortgages. However, they can offer tax advantages, including different ways of structuring profits and expenses. We can help you compare both options and determine which approach best suits your investment strategy.
How Much Deposit Do I Need?
A larger deposit can help secure better mortgage rates. While some lenders allow BTL mortgages with a 15% deposit, most require at least 25% of the property’s value. Higher deposits often mean access to lower interest rates and better overall mortgage deals.
It’s also important to factor in additional costs, such as mortgage fees, legal fees, and potential refurbishment expenses, when planning your investment.
Do I Need a Survey for a Buy to Let Property?
Yes, a survey is recommended before purchasing a Buy to Let property. This can help identify any structural issues that may require costly repairs. There are different levels of surveys available, and we can guide you on which type best suits your needs.
Additionally, your lender will require a mortgage valuation to ensure the property is worth the amount you’re borrowing. This helps the lender assess the risk and confirm they are willing to provide the loan.
