Can you change your mortgage to a buy-to-let?

As a homeowner, you may find yourself in a position where you want to rent out your property instead of living in it. This is especially common in the UK, where the buy-to-let market is thriving. But can you change your existing residential mortgage to a buy-to-let mortgage? In this article, we’ll explore the process of switching your mortgage and discuss important factors to consider.

Can you change your mortgage to a buy-to-let?

Understanding by-to-let mortgages

A buy-to-let mortgage is a type of mortgage specifically designed for landlords who want to purchase a property to rent out. It differs from a traditional residential mortgage in several ways, including the interest rates, lending criteria, and the way affordability is assessed. Lenders typically require a larger deposit for a buy-to-let mortgage (usually around 25% of the property value) compared to a residential mortgage, and they may also charge higher fees and interest rates.

Can I change my mortgage to a buy-to-let?

In many cases, it is possible to change your residential mortgage to a buy-to-let mortgage, provided you meet certain criteria. Here are the key steps involved in the process:

Speak to your current lender: Before making any changes, it’s essential to discuss your plans with your current mortgage provider. Some lenders may be willing to grant a “consent to let” agreement, which allows you to rent out your property without switching to a buy-to-let mortgage. This can be a temporary or permanent arrangement, depending on the lender’s policy.

Assess your affordability: If your lender requires you to switch to a buy-to-let mortgage, you’ll need to ensure you meet the affordability criteria. This may involve providing proof of income and an assessment of your existing financial commitments. Keep in mind that lenders may require you to have a higher level of rental income than your mortgage repayments, typically around 125% to 145% of the monthly mortgage payment.

Apply for a new mortgage: If you meet the affordability requirements, you can apply for a new buy-to-let mortgage. This may involve paying additional fees and undergoing a new property valuation. Be prepared to provide documentation such as proof of identity, proof of income, and details of your rental plans.

Pay off your existing mortgage: Once your new buy-to-let mortgage is approved, you will need to pay off your existing residential mortgage. This is typically done by using the funds from your new mortgage to pay off the outstanding balance on your old one.

Important factors to consider

Before you decide to switch your mortgage, consider the following factors:

Tax implications: Renting out your property can have tax implications, such as the need to pay income tax on rental income and potential capital gains tax when selling the property. Be sure to consult a tax professional to understand the implications of becoming a landlord.

Landlord responsibilities: Becoming a landlord comes with additional legal and financial responsibilities, such as ensuring the property meets safety standards and managing tenant issues. Make sure you are prepared to take on these responsibilities before switching your mortgage.

Market conditions: The buy-to-let market can be volatile, and property values may fluctuate. Research the local rental market to ensure there is sufficient demand for your property and that you can achieve the rental income you require.

In summary, switching your mortgage from residential to buy-to-let can be a viable option for homeowners looking to enter the rental market. However, it’s essential to consider the financial implications, responsibilities, and market conditions before making the switch. Be sure to consult with your current lender and seek professional advice to ensure you make the best decision for your circumstances.


Can I change my residential mortgage to a buy-to-let mortgage?

Yes, you can change your residential mortgage to a buy-to-let mortgage. This process involves switching from a mortgage designed for a home you live in into one meant for a property you rent out. It’s important to notify your lender and get their approval for this change.

What is the process for switching to a buy-to-let mortgage?

The process typically involves:

  • Contacting your current lender to discuss your plans.
  • Applying for consent to let if you wish to stay with your current lender.
  • Refinancing with a buy-to-let mortgage if your current lender doesn’t offer suitable terms.
  • Undergoing a new affordability assessment and valuation of the property.

Do I need permission from my current lender to switch to a buy-to-let mortgage?

Yes, you need permission from your current lender. This is often referred to as “consent to let.” Without this permission, renting out your property could violate the terms of your residential mortgage agreement.

What is “consent to let”?

“Consent to let” is a temporary agreement from your mortgage lender allowing you to rent out your property without switching to a buy-to-let mortgage. This is usually a short-term solution, and lenders may charge a fee or adjust the interest rate for this arrangement.

Will I need to pay any fees to switch to a buy-to-let mortgage?

Yes, there may be fees involved in switching to a buy-to-let mortgage. These can include early repayment charges if you’re leaving your current deal early, arrangement fees for the new mortgage, and possibly a valuation fee.

How will switching to a buy-to-let mortgage affect my interest rates?

Buy-to-let mortgages often have higher interest rates compared to residential mortgages. The exact rate will depend on factors like the lender, your financial situation, and the property’s rental income potential.

Are there any tax implications when switching to a buy-to-let mortgage?

Yes, there are tax implications. Rental income is subject to income tax, and you may also need to consider capital gains tax if you sell the property. It’s advisable to consult a tax advisor to understand your obligations.

What if my current lender doesn’t offer buy-to-let mortgages?

If your current lender doesn’t offer buy-to-let mortgages or suitable terms, you can remortgage with a different lender that does. This will involve paying off your existing mortgage and taking out a new buy-to-let mortgage.

How is rental income considered in a buy-to-let mortgage application?

Lenders will assess the potential rental income of the property to ensure it can cover the mortgage payments. Typically, they look for rental income to be 125% to 145% of the mortgage repayments, depending on their criteria.

Can I live in the property if I have a buy-to-let mortgage?

No, a buy-to-let mortgage is specifically for properties that you rent out to tenants. If you wish to live in the property, you would need to switch back to a residential mortgage.

What happens if I rent out my property without changing to a buy-to-let mortgage?

Renting out your property without notifying your lender and obtaining consent to let or switching to a buy-to-let mortgage can breach your mortgage terms. This can lead to serious consequences, including the lender demanding immediate repayment of the loan.

Can I switch back to a residential mortgage if I stop renting out my property?

Yes, if you decide to stop renting out your property and move back in, you can switch back to a residential mortgage. You’ll need to go through the application process with your lender to make this change.
