Buy To Let Remortgage
Buy To Let
Remortgage
A buy-to-let remortgage replaces the existing deal on a property you rent out with new terms, allowing you to secure a better rate, adjust the mortgage to suit your current financial goals, or release equity. These funds can then be used to expand your portfolio, renovate properties, or support other goals.
What Is A Buy To Let Remortgage?
A buy-to-let remortgage is when you switch your mortgage on a property you rent out. You can either move to a new lender or stay with your current lender and take a new deal, often called a product transfer.
Unlike the initial mortgage when you first bought the property, a buy-to-let remortgage replaces your existing deal with new terms. This can help you secure a better rate, release equity, or adjust the mortgage to suit your current financial goals.
Are They Different To A Residential Remortgage?
A buy-to-let remortgage differs from a standard residential remortgage in a few key ways:
Purpose of the Property
Buy-to-let mortgages are for properties you rent out, whereas residential mortgages are for homes you live in.
Lender Criteria
Lenders usually assess rental income, potential yield, and landlord experience for buy-to-let, rather than your personal income and affordability alone.
Deposit Requirements
Buy-to-let mortgages often require a larger deposit, typically 20–25% or more, compared with residential mortgages.
Interest Rates
Rates on buy-to-let mortgages may be slightly higher due to the increased risk for lenders.

Things to Consider
Benefits
Lower Interest Rates
One of the main reasons landlords remortgage is to secure a better interest rate. A lower rate can reduce monthly repayments and improve your overall cash flow, helping make the investment more profitable.
Release Equity
If the value of your rental property has increased, a buy-to-let remortgage can allow you to release equity. The funds you free up can be used for further investments, renovations, or other financial goals.
Switching Lenders
Switching to different buy-to-let mortgage product lenders could help you to secure more competitive deals with more favourable terms.
Fund Renovations
A buy-to-let remortgage can also fund property improvements. Upgrading a rental property can increase its value and appeal, potentially improving your rental income and long‑term returns.
Risks and Considerations
Fees Can Apply
Various costs can come with remortgaging, including arrangement fees, valuation fees, legal fees and early repayment charges (ERCs) from your current lender. These can affect how much you ultimately save.
Rental Income Assessment
Lenders will usually assess the rental income your property generates as part of affordability. If the rental income does not comfortably cover the new mortgage costs, some lenders may be more cautious.
Valid Reason for Remortgaging
Lenders typically want to understand why you’re remortgaging, such as to lower your rate, release equity, or adjust your product. You should be prepared to explain your motivation and how the new deal supports your long‑term goals.
Impact on Investment Returns
Being a landlord comes with ongoing costs and responsibilities. You’ll need to cover mortgage payments even if the property is empty, as well as repairs or emergency expenses like boiler replacements.
How Does A Buy To Let Remortgage Work?
When remortgaging a buy-to-let property, the process usually starts with the lender assessing the property’s value and your current financial situation.
A mortgage broker will review your circumstances and the range of available rates to help find the most cost-effective deal for you at the time.
Each lender has its own criteria, so it’s important to be matched with the deal that best suits your needs.
Keep in mind that remortgaging can affect your monthly repayments and the return on your investment, so it’s essential to ensure this type of remortgage aligns with your long-term goals.

How To Apply For A Buy To Let Remortgage
Rental potential
Lenders assess the rental potential of the property you’re looking to buy. In most cases, your projected rental income is used to calculate how you will make the mortgage repayments. Some lenders may require a rough estimate of your expected rental income, which should come from an Association of Residential Letting Agents, registered letting agent to ensure accuracy and reliability.
Income
Personal affordability plays a lesser role in buy-to-let mortgages compared to residential mortgages. However, it’s important to note that many buy-to-let lenders impose a minimum income requirement. This means that while your rental income is critical, lenders will still consider your overall financial situation before approving your application for a mortgage.
Employment status
There are no specific rules set by lenders regarding how you generate your income, allowing individuals with diverse income sources to qualify for buy-to-let mortgages and making property investment accessible. For instance, being self-employed is perfectly acceptable, as being a landlord is essentially considered a self-employed role.

Frequently asked questions
Got questions? Let’s answer them
What is a buy-to-let remortgage?
A buy-to-let remortgage is when you switch your mortgage on a property you rent out. You can either stay with your current lender with a new deal (product transfer) or move to a different lender for potentially better rates or terms.
How is it different to a residential remortgage?
A buy-to-let remortgage differs from a standard residential remortgage in a few ways, including:
- Purpose of the property: Buy-to-let mortgages are for properties you rent out, whereas residential mortgages are for homes you live in.
- Lender criteria: Lenders usually assess rental income, potential yield, and landlord experience for buy-to-let, rather than your personal income and affordability alone.
- Deposit requirements: Buy-to-let mortgages often require a larger deposit, typically 20–25% or more, compared with residential mortgages.
- Interest rates: Rates on buy-to-let mortgages may be slightly higher due to the increased risk for lenders.
Can you change a residential mortgage to a buy-to-let mortgage?
Yes, you can do this either through your current lender with their permission and guidance, or by remortgaging your residential mortgage to a buy-to-let mortgage with a new lender.
Additional fees may be charged by your lender to make this change. If your existing lender doesn’t consent to changing your residential mortgage to a buy-to-let arrangement, you can apply to switch your mortgage to a dedicated buy-to-let product with a different lender.
Is a buy-to-let remortgage more expensive than a residential remortgage?
Not always, but buy-to-let mortgages can have slightly higher interest rates and larger deposit requirements, typically 20–25% or more, because lenders see rental properties as higher-risk investments.
How does a buy-to-let remortgage work?
With a buy-to-let remortgage, the process usually starts with the lender assessing the property’s value and your current financial situation.
A mortgage broker will review your circumstances and the range of available rates to help find the most cost-effective deal for you at the time.
Each lender has its own criteria, so it’s important to be matched with the deal that best suits your needs.
What are the different types of buy-to-let mortgage?
The different types of buy-to-let remortgages are usually categorised by how interest is charged. Main options include:
- Fixed rate: Interest rate is locked for a set period, meaning your monthly payments stay the same.
- Tracker rate: Interest rate tracks the Bank of England base rate plus a fixed percentage, meaning your monthly payments can go up or down depending on base rate changes.
- Standard Variable Rate (SVR): Interest rate is a flexible rate set independently by your mortgage lender. If you don’t remortgage at the end of your term, you’ll usually be automatically switched onto this often much higher rate.
- Discounted variable rate: Interest rate is set at a specific discount below the SVR, meaning your monthly payments can go up or down depending on SVR changes.
How long does a buy-to-let remortgage take?
The process typically takes 4–8 weeks, depending on lender requirements, property valuations, and whether you switch to a new lender or stay with your existing one.
What fees are involved?
Various fees are associated with a buy-to-let remortgage, including product and arrangement fees, property valuation fees, solicitor and legal fees, and early repayment charges from your current lender – if you decide to remortgage with a different lender before the end of your existing term.
Can I release equity when remortgaging a buy-to-let?
Yes. If your property value has increased, remortgaging can allow you to release equity, which can be used for renovations, additional investments, or other financial goals.
Do I need to show rental income when remortgaging?
Yes. Lenders usually assess your rental income to ensure it comfortably covers your new mortgage repayments. This helps them calculate affordability and approve the remortgage.
