Home – Buy to Let Mortgage
A buy-to-let mortgage is specifically designed for purchasing a property that you intend to rent out rather than live in. It’s commonly used by landlords looking to generate rental income.
Like a standard mortgage, you’ll need to provide a deposit and borrow the remaining amount from a lender, which is then repaid over an agreed term. However, buy-to-let mortgages usually come with stricter criteria and often require a larger deposit compared to residential mortgages.
When it comes to investment properties, lenders focus mainly on the expected rental income rather than just your personal earnings. The amount you can borrow is typically based on the property’s rental yield.
In some cases, lenders may also review your personal finances—or your company’s finances if you’re purchasing through a limited company. Generally, lenders require the rental income to not only cover the mortgage repayments but exceed them by around 25% to 45%, helping to account for costs such as taxes, maintenance, and insurance.
Interest Rates Buy-to-let mortgages typically carry slightly higher rates due to the commercial and elevated risk associated with this type of investment.
Buy-to-let mortgages often utilize interest-only repayments, while residential mortgages are commonly based on capital repayment
Buy-to-let mortgage fees are typically higher and calculated as a percentage of the property value, although feefree options are available.
Generally, a minimum of 25% of the property value is necessary for buy-to-let mortgages, unlike residential mortgages, where 5% may suffice at times.
The criteria for buy-to-let mortgages are usually more stringent and comprehensive than those for personal homes.
Buy-to-let mortgage approval is primarily determined by rental yield rather than personal financial capability and credit rating, although these factors are also taken into account
While most buy-to-let mortgages are not regulated by the Financial Conduct Authority (FCA), exceptions exist, such as consumer buy-to-let and regulated (or family) buy-to-let mortgages.
As with other mortgage types, the size of your deposit plays a key role in securing favorable rates. A larger deposit reduces the loan-to-value (LTV) ratio, making you a lower-risk borrower in the eyes of lenders.
For buy-to-let mortgages, deposits typically start at 25%. However, aiming for around 40% can significantly lower your LTV to 60%, often unlocking the best available rates. A bigger deposit reduces lender risk, which can translate into more competitive interest rates for you.
Buy-to-let mortgages share similarities with standard residential mortgages, offering both fixed-rate and variable-rate options.
In addition, there are some unique buy-to-let mortgage options designed specifically for property investors, including:
In some specific cases, it’s possible to obtain a buy-to-let mortgage with FCA protection, similar to a standard residential mortgage. These include:
Recently, more investors are buying properties through limited companies rather than as individual landlords. This trend is largely driven by changes in tax rules, including the loss of mortgage interest tax relief and restrictions on using rental expenses to reduce personal tax, which can affect profitability.
A limited company buy-to-let mortgage usually involves a Special Purpose Vehicle (SPV)—a company created specifically for purchasing, managing, and selling residential properties.
Because tax regulations differ for companies compared to individuals, this structure can offer a more efficient and profitable way to manage property investments.
A let-to-buy isn’t a separate type of mortgage, but rather a scenario where you hold two mortgages at the same time.
Typically, this occurs when you refinance your existing residential property as a buy-to-let while also taking out a new mortgage to purchase another home.
This setup can help you cover your current mortgage if you want to move but aren’t ready—or able—to sell your existing property.
In recent years, buying property through a limited company has become increasingly popular compared to purchasing as an individual landlord. This trend is largely due to changes in tax rules, such as the removal of mortgage interest relief and restrictions on using rental expenses to reduce personal tax, which can affect overall profitability for individual landlords.
A limited company buy-to-let mortgage is usually arranged via a Special Purpose Vehicle (SPV)—a company created specifically to buy, manage, and sell residential properties. Because companies are subject to different tax regulations than individuals, this method can provide a more efficient and potentially more profitable way to manage investment properties.
If you’re planning to invest in an HMO (House of Multiple Occupancy)—such as a student rental property—it’s important to work with a lender that offers mortgages for this property type. Not all lenders provide buy-to-let mortgages for HMOs, and eligibility requirements may differ.
Despite the additional considerations, HMO properties often offer higher rental yields compared to single-family homes. Contact us to explore the best options and secure the right financing for your HMO investment.
Most lenders require borrowers to be at least 18–25 years old, while upper age limits tend to be more flexible than for residential mortgages. If you’re approaching retirement age, it’s worth seeking advice to understand your options.
Some lenders prefer applicants to already own a residential property, but this isn’t always mandatory.
Lenders usually assess your personal or business income, and some may impose a minimum income requirement.
The main focus is typically the rental income from the property you wish to purchase. Many lenders require an ALRA-registered letting agent to verify the potential rental income. For specialized buy-to-let mortgages, additional rules may apply—for example, HMO mortgages often come with restrictions on the total number of bedrooms.
Your personal or company credit history will influence the lender’s decision. Some flexibility may exist if your property has a high rental yield or if you already have a successful portfolio of investment properties.
There are lenders who specialize in applicants with lower credit scores, but expect higher interest rates in exchange for this option.
Investing in buy-to-let property comes with several tax considerations, so it’s important to factor these into your overall profit planning.

if you are looking to go with interest only mortgage, which most landlords do, you will need to know how you will repay the loan at the end of the mortgage terms, 25, 30 or 35 years terms. The bank/lender will want to know this, it could be by sale of the property, investment income, pension or other means.


We will need to see proof of deposit, Income records, bank details, and personal ID documents like proof of address & passport. if you are buying under a Limited company need the company registered as SPV (special Purpose Vehicle), company bank account details.
As your fixed-rate period comes to an end, your monthly repayments may increase when you move onto your lender’s standard variable rate. Rather than simply accepting their next offer—which may not be the most competitive—we explore a range of remortgage options tailored to your needs.
Speaking with us early can give you peace of mind, help you maintain a stable monthly budget, and potentially save you a significant amount over time.
If you’ve made overpayments, paid off a lump sum, or your property value has increased, you may now qualify for a lower loan-to-value (LTV) band.
A lower LTV often means access to better mortgage deals and lower interest rates. We’ll review your situation, check for any early repayment charges, and calculate how much you could potentially save each month by remortgaging at the right time.
If you’ve built up equity in your home, remortgaging can allow you to access those funds for a variety of purposes. This could include home improvements, extensions, or consolidating existing debts.
Using your home equity can often provide more competitive interest rates compared to personal loans or other borrowing options. We’ll carefully assess your circumstances and walk you through all available remortgage options, ensuring you fully understand the benefits and implications before making a decision.
