Thinking of buying a second property? Whether it’s for extra space, family use, a future investment, or even the occasional getaway, many people eventually find themselves asking, “Can I get a second mortgage?” The short answer is yes, second home mortgages are entirely possible and far more common than you might think. However, the process can feel quite different from buying your first home. Lenders look more closely at your overall financial position, from your existing mortgage commitments to your long-term affordability. You’ll also need to consider how much of a deposit you can put down, what type of second property you want to buy, and how the lender’s criteria change depending on whether it will be used privately, rented out, or treated as an investment. Understanding these factors early on can make the journey to owning a second property much smoother.
What Is a Second Mortgage?
To put it simply, it is an additional mortgage you take out on top of your existing one. There are two main routes:
Second home mortgage – A standard mortgage used to purchase a completely different property while keeping your current residence.
Second charge mortgage – A different product entirely and covered separately in another guide.
Provided that a lender is satisfied you can afford repayments on both loans, it is a viable option for many people looking to expand their mortgage borrowing and property funding. That’s why speaking to a mortgage broker experienced in second residential mortgage options is so helpful.
Can I Get a Second Mortgage to Buy Another Home?
The answer to this question will really depend on a few key factors:
Affordability
Lenders need to be confident that you can comfortably afford both your existing mortgage and the repayments on your new second home mortgage. When you apply for a second loan on a property, the combined monthly payments are assessed using the lender’s full affordability model, which takes into account your income, regular outgoings, debts, financial commitments, and even future interest rate changes. Because your overall level of borrowing becomes higher, lenders typically apply stricter affordability rules to make sure you won’t be overstretched. This means your income, spending habits, and financial stability are all under closer scrutiny than they might have been with your first mortgage.
Credit History
A strong credit score makes getting any type of mortgage significantly easier, and second home mortgages are no exception. Lenders use your credit history to judge how reliably you’ve managed borrowing in the past, and whether you’re likely to keep up with repayments going forward. If your credit score is weak or you have recent credit issues, some lenders may be hesitant to take on the extra risk of approving a second mortgage. That said, a less-than-perfect score doesn’t automatically rule you out, it just means specialist advice and a more tailored search for suitable lenders becomes even more important.
Deposit Levels
Most second home loans and mortgages for second homes require a larger deposit than a standard main residence mortgage. This is partly because lenders tend to view second properties as slightly higher-risk and therefore want you to contribute more upfront. The amount you’ll need can vary depending on your financial circumstances, the type of second property mortgage you’re applying for, and whether the home is for personal use, family use, or investment purposes. Generally, the bigger your deposit, the broader your choice of lenders and interest rates, which can make the borrowing more affordable overall.
Purpose of the Property
How you plan to use the property plays a major role in shaping the type of mortgage you’ll be offered. Lenders differentiate between second homes you intend to live in occasionally, properties you want to let out, and homes purchased purely for investment potential. If you’re planning to rent the property or use it as a holiday let, you may need a specific mortgage product designed for that purpose. While holiday homes and investment properties are common motivations for taking out a second loan, this guide focuses mainly on general second-home use, properties purchased for personal enjoyment, family convenience, or additional living space.
Location
Lenders also consider the practicality and overall viability of the purchase. A mortgage for a second property right around the corner from your main residence may prompt questions about why the additional home is needed, and whether it truly qualifies as a second property. On the other hand, a second residence in another area, whether for work, family, or lifestyle reasons, is usually easier to justify. Location can also influence lender confidence if market demand, property values, or local conditions differ from your primary home’s area, making it an important factor in the approval process.
How to Get a Second Mortgage
Here’s the process:
Review your finances – Understand your affordability using a mortgage calculator or by speaking with a broker.
Check your credit report – Improve errors or weak areas before applying.
Prepare your documents – Income, debts, bank statements, property information.
Compare lenders – Not all lenders offer these types of loans, so using a broker can be essential.
Apply for mortgage approval – The lender will run checks to determine whether you meet their criteria.
Can I Get a Second Home Mortgage?
To approve a second home mortgage or 2nd home mortgage, lenders will review:
- Income and outgoings
- Your current mortgage balance
- Your credit score
- The purpose of the second property
If you’re unsure how much you could borrow, brokers can help you get pre-assessed before you officially apply for mortgage products.
How Much Can I Borrow on a Second Mortgage?
One of the most common questions is: “How much can I take out on a second mortgage?”. Like all mortgages, you will need to be assessed by the mortgage lender (bank or building society) to determine how much you can actually borrow.
The lender will base this on:
- Debt-to-income ratio
- Existing mortgage payments
- Potential rental income (if applicable)
- Deposit size
- Property value
As with any mortgage, the stronger your income and the lower your debts, the more likely you can get another mortgage, with favourable terms. The higher your debt-to-income (how much monthly debt you pay compared to how much is coming in), the less the lender will be willing to lend you.
How Much Deposit Do I Need for a Second Mortgage?
Most second-property lenders look for 15–25%, though this varies with some lenders requiring 40% or more depending on their own criteria and your own mortgage affordability. All of this will be considered and evaluated by your mortgage adviser for you. Many people use equity from their current home to help fund the deposit for a mortgage second home purchase.
A larger deposit generally means:
- Lower risk for lenders
- More competitive mortgage rates
How Much Does a Second Mortgage Cost?
Many buyers ask whether second loan rates are higher than on main residence mortgages. If you do find yourself in the privileged position to be able to purchase a second property, then generally every cost will go up! Including taxes. But typically the following are considerations that need to be taken into account.:
- Second home mortgage rates can be higher, due to the increased lender risk.
- Arrangement, valuation and legal fees may also apply.
- Monthly repayments depend on the mortgage term, borrowing amount and general market conditions.
Can I Afford a Second Mortgage?
The ultimate question! Mortgage affordability is one of the most important parts of getting a new mortgage of any kind. If you can’t afford to borrow what you need, then your new mortgage application will be dead in the water. As well as income, there are other factors that you must include in your mortgage affordability calculations. Before taking out another loan, you MUST consider:
- Council tax, insurance and maintenance
- Utility bills
- Possible periods of vacancy if you later rent it out
- Rate changes over time
- Leaving a financial buffer for unexpected expenses
- Being realistic now can prevent financial strain later.
How Quickly Can You Get a Second Mortgage?
There’s no strict rule. Some lenders prefer you to have held your current mortgage for 6–12 months before applying for a 2nd property mortgage. Others may consider applications sooner if income and equity are strong.
Speak to a Mortgage Advisor
So, it absolutely is possible, but it does require some careful planning and a clear understanding of what lenders are looking for.

Every situation is unique, and having someone who can explain the options, assess your affordability, and highlight any potential hurdles can make the whole process far less daunting.
