When does Let to Buy actually make sense?
Let to buy makes sense when your current home can cover its own mortgage through rental income, and you can still comfortably qualify for a residential mortgage on the new one. Get that balance wrong and it turns into an expensive way to hold onto a property you should have sold.
For many homeowners, it’s a natural way to build a portfolio as they move into the next stage of life, without giving up a home they’re not ready to part with. But it comes with extra costs, extra admin, and extra risk, so it’s worth understanding exactly how it works before committing.
This guide covers what let to buy is, how it differs from buy to let, the advantages and disadvantages, and what to check before you apply.
What is Let to Buy?
Let to buy means keeping your current home as a rental property instead of selling it, while buying a new one to live in. Your existing mortgage switches to a buy to let mortgage, which frees you up to take out a standard residential mortgage on the home you’re moving into.
What is a Let to Buy Mortgage?
A Let to Buy mortgage allows you to rent out your current home while buying another property to become your main new residence.
Typically, your existing residential mortgage is replaced with a Let to Buy or Buy to Let mortgage, subject to the lender’s criteria, and you take out a separate residential mortgage on your new home.
Instead of selling your current property, you keep ownership of it and become a landlord. The aim is that the property generates rental income and may also increase in value over time, although property values can rise or fall and future performance can never be guaranteed.
Let to Buy can be particularly popular with couples who each own a property before moving in together. Rather than selling one home immediately, one property can become the family home while the other is rented out, allowing both parties to retain ownership of their existing property.
Why do people choose Let to Buy?
There are many reasons why homeowners decide to keep their current property instead of selling it.
Some people are relocating for work but hope to return to the area in the future. Others have built up significant equity and are financially able to own more than one property. Some simply see long term value in retaining a property that is likely to attract reliable tenants.
For homeowners interested in building wealth over time, keeping a property can provide two potential benefits. The first is rental income, which may help cover the mortgage and ongoing costs. The second is any future growth in the property’s value, although property prices can move both up and down.
Of course, becoming a landlord also means taking on additional responsibilities, and it is important to be comfortable managing these before proceeding.
When might Let to Buy be a good option?
A Let to Buy mortgage may be suitable if you do not need to rely on selling your current property to fund your next purchase. Having sufficient equity in your existing home and a stable income can make it easier to qualify for both mortgages.
It may also be worth considering if your current property is located in an area with strong rental demand and the expected rental income is likely to support the mortgage and other ownership costs.
However, every situation is different. What works well for one homeowner may not be appropriate for another, which is why professional mortgage and financial advice can be valuable before making a decision.
Should you rent out your home or sell it?
One of the biggest questions homeowners face is whether it makes more sense to keep their existing property or sell it.
There is no universal answer because it depends on your finances, your long-term plans, and the housing market.
If property prices increase over time, retaining your existing home could help you build additional wealth. On the other hand, if property prices fall, the value of your investment could decrease.
Many people take a long-term view when investing in property, recognising that housing markets naturally experience periods of growth and decline. However, no one can accurately predict future property prices, so decisions should not be based solely on market expectations.
How do mortgage rates compare?
Before renting out your current property, you should check the terms of your existing mortgage.
Most residential mortgages do not automatically allow you to let the property to tenants. If you rent it out without your lender’s permission, you could breach your mortgage conditions.
In some situations, your lender may offer Consent to Let. This is usually intended as a temporary arrangement, often for homeowners who need to move away for a limited period while keeping their existing residential mortgage.
If Consent to Let is not available or your plans are long term, you may need to switch to a Let to Buy or Buy to Let mortgage instead.
Changing your mortgage could involve additional costs, including early repayment charges if you leave your current deal early, arrangement fees, valuation fees, legal costs, and other lender charges.
Can you afford two properties?
Owning two properties naturally increases your financial commitments.
Although rental income may help cover the mortgage on your existing property, there may be times when the property is vacant or unexpected expenses arise. It is important to consider whether you could comfortably manage both mortgages if your rental income temporarily stopped.
Lenders will also assess whether your income and the expected rental income meet their affordability requirements before approving your application.
Having a larger amount of equity in your existing property can often improve your options, but each lender uses its own affordability assessment and lending criteria.
Understanding the costs of being a landlord:
Many first-time landlords focus primarily on the mortgage, but there are several other costs that should be factored into your
calculations.
You may experience periods where the property is empty between tenants, meaning there is no rental income coming in. You will also remain responsible for maintenance and repairs, whether that involves replacing a boiler, repairing a roof, or dealing with general wear and tear.
If you choose to use a letting agent, you should also budget for management fees. Landlord insurance, safety certificates, and ongoing maintenance costs should all be included when assessing whether Let to Buy is financially sustainable. Building a financial buffer for unexpected expenses can help reduce pressure if things do not go exactly as planned.
The costs of buying your new home:
Keeping your existing property is only one part of the financial picture. You also need to consider the cost of purchasing your new home, including your new residential mortgage payments, legal fees, survey costs, moving expenses, and Stamp Duty Land Tax where applicable.
If you are buying an additional property in England or Northern Ireland, you will usually pay the higher rate of Stamp Duty because you will own more than one residential property at the time of completion.
Depending on your circumstances, you may be able to reclaim the additional Stamp Duty if you later sell your previous main residence within the time limits set by HM Revenue and Customs. Eligibility rules apply, so professional tax advice may be appropriate.
How is rental income taxed?
Rental income may be subject to income tax, and landlords are responsible for declaring any taxable rental income to HM Revenue and Customs where required.
The tax treatment of rental income depends on your individual circumstances and current tax legislation, which can change over time. Tax rules relating to mortgage interest relief and allowable expenses have also changed significantly in recent years.
Because tax can have a major impact on the profitability of a rental property, it is sensible to speak with a qualified tax adviser or accountant before proceeding with a Let to Buy arrangement.
Will you pay Capital Gains tax?
When you eventually sell a property that is no longer your main residence, Capital Gains Tax may apply if the property has increased in value.
The amount of tax payable depends on several factors, including how long the property was your main residence, when it was rented out, your overall taxable income, and the Capital Gains Tax rules in force at the time of sale.
Tax legislation changes regularly, so it is important to seek professional tax advice based on your personal circumstances rather than relying on general guidance.
How Is Let to Buy Different from Buy to Let?
Although the two mortgage types sound similar, they are designed for different situations.
A Buy to Let mortgage is typically used when you are purchasing a property specifically as an investment or refinancing an existing rental property.
A Let to Buy mortgage is designed for homeowners who already live in a property but want to keep it as a rental while buying another home to live in themselves.
The distinction is important because lenders assess these applications differently and often have separate eligibility criteria.
What are the lending criteria for Let to Buy Mortgages?
Every mortgage lender has its own lending policy, so criteria will vary.
Many lenders will assess the expected rental income from your existing property alongside your personal income and affordability for your new residential mortgage.
Some lenders may limit the maximum loan to value available, require evidence that you are purchasing a new main residence, and apply maximum age limits at the time of application or at the end of the mortgage term.
Because lending criteria differ significantly between providers, working with a mortgage broker can help identify lenders whose requirements best suit your circumstances.
What are the advantages of Let to Buy?
For many homeowners, Let to Buy provides greater flexibility than selling immediately.
It can reduce the pressure of trying to coordinate the sale of one property with the purchase of another, helping to simplify what can otherwise be a stressful property chain.
Keeping your existing property also allows you to retain an investment that may generate rental income while potentially benefiting from long term capital growth, although future property values cannot be guaranteed.
What are the potential downsides?
Let to Buy is not suitable for everyone.
You will usually be responsible for two mortgages, which increases your financial commitments. Mortgage rates on Let to Buy borrowing may also be higher than standard residential mortgage rates.
If your property remains vacant, you will still need to meet your mortgage payments. There is also the possibility that property values could fall, affecting both homes you own.
In addition, becoming a landlord involves legal responsibilities, ongoing maintenance, and compliance with rental regulations.
Is Let to Buy Right for you?
A Let to Buy mortgage can be an effective solution for homeowners who want to move without giving up ownership of their existing property. It offers flexibility, the opportunity to generate rental income, and the potential to build a long-term property investment.
However, it also involves greater financial responsibility, additional costs, and the practical realities of becoming a landlord. Before making a decision, it is important to carefully assess your finances, understand the risks, and consider both the short term and long-term implications.
