What is Stamp Duty?

When you’re buying a home, you’ll likely hear the term: stamp duty. But what exactly does it mean, and how might it affect your property purchase?

Stamp duty is a land tax that you’re required to pay on property purchases. The rate you’re required to pay can vary depending on factors like the price of the property, whether it’s your first home or not, and where in the UK the property is situated.

You might be thinking: “Why is it called stamp duty?” The name goes back to the days when legal documents were validated by a physical stamp. Though we’re now in a digital age, the name has stuck around.

It’s also important to know there are different types of stamp duty. Stamp Duty Land Tax (SDLT) applies to England and Northern Ireland, while Land and Buildings Transaction Tax (LBTT) is for Scotland and Land Transaction Tax (LTT) is in place for Wales. Each has its own set of rules and rates.

The price, the type of property (residential or non-residential), and the status of the buyer (first-time buyer, homeowner or buy-to-let/investment) determines how much stamp duty you’ll pay.

You also need to pay stamp duty on leasehold properties. In these cases, the tax applies to both the lease’s purchase price and its annual rent. But remember, as with freehold property, tax rates can vary.

Understanding stamp duty is key when you are budgeting for a home purchase. As part of your pre-purchase considerations, determine whether you have enough savings to cover this cost upfront, or whether it’s better for you to add stamp duty to your mortgage.

How does Stamp Duty Affect Your Mortgage?

Once you’ve grasped the concept of stamp duty as a land tax, you’ll undoubtedly be wondering about its impact on your mortgage. Here, we delve into the nuts and bolts of it all.

Stamp duty might not be the first thing you think about when applying for a mortgage. Usually, mortgage calculations are based on the price of the property alone. Yet stamp duty can significantly increase the size of your mortgage if you choose to add it to the loan total. This decision might initially seem appealing, as it reduces the upfront costs. But it’s essential to be aware of the consequences.

By adding the cost of stamp duty to the mortgage, you’re essentially borrowing more money from the lender. Remember, this isn’t just a one-time cost; it’s an amount that you’ll be paying interest on for the duration of the mortgage term. While it may render the property purchase more accessible initially, you could end up paying more in the long run due to the accumulated interest.

Moreover, the additional borrowing might push you into the next Loan-to-Value (LTV) band which can carry a higher interest rate. This potentially means you’re subject to:

  • Higher interest rates affecting your monthly payments
  • More difficulty in switching mortgage products if a better deal comes along
  • Higher risk of falling into negative equity if house prices fall.

As responsible property buyers, you need to be mindful of these potential pitfalls. Understanding the impact of stamp duty on your mortgage, you can plan more efficiently and make informed decisions about what’s manageable for you to pay now, and in the future.

Pros of Adding Stamp Duty to Your Mortgage

While there are potential drawbacks to consider, there are certainly advantages to adding stamp duty to your mortgage. It might seem daunting to increase your loan amount, but there’s a number of potential benefits you should consider.

Firstly, it’s about cash flow. By adding the cost of stamp duty to your loan, you can relieve immediate financial pressure. This might be particularly advantageous if you’ve already stretched your budget to gather a deposit and cover the cost of moving house. With this method, you’re effectively spreading the tax burden over the term of your mortgage, rather than paying it all upfront.

Another advantage is that you can potentially provide yourself with extra immediate liquidity. This is especially useful if you foresee necessary refurbishments or improvements you’d like to make to the property immediately after purchase. Remember, homes are never perfect and it’s often the case that you’ll want to make changes once you’ve moved in. Having the extra financial buffer can provide peace of mind and flexibility.

Thirdly, adding the stamp duty to your mortgage could allow you better budgeting and financial planning. It’s easier to plan around a known, consistent monthly payment than dealing with ad hoc large cash outlays. The predictability of knowing what your mortgage repayment is each month allows for more strategic planning, helping you manage your money more effectively in the long-term.

Finally, integrating stamp duty into the loan might make sense if you believe property prices will rise in the future. Should the value of your property increase significantly, the added cost of borrowing this extra money could be offset by the capital appreciation of your home.

These are some of the key positives to reflect on when contemplating rolling stamp duty into your mortgage. You’re taking a bold step towards becoming a property owner in the UK, so it’s crucial that you consider every angle before making your final decision. And always be sure to get advice from a knowledgeable professional when handling such a significant financial commitment.

Cons of Adding Stamp Duty to Your Mortgage

While it may seem appealing to wrap up your stamp duty tax into your mortgage, it’s not without its drawbacks. This option may ease the immediate financial pressure, but let’s consider the flip side.

One of the key issues to be aware of is increased interest payment. By adding your stamp duty to your mortgage, you’ll naturally increase the total mortgage amount. This means you’ll be paying interest on a larger amount for the life of your mortgage.

Suppose you add £10,000 of stamp duty to a 25-year mortgage with an interest rate of 3%. Over the term of your mortgage, you could end up paying around £3,000 extra in interest. That’s a hefty sum!

Moreover, your loan-to-value ratio (LTV) also impacts. It describes the relationship between borrowed amount and property’s worth. By adding stamp duty to your mortgage, you’re increasing your LTV Ratio. A higher LTV Ratio can make it harder to secure favourable mortgage deals in the future, and may also come with higher rates now.

And remember, there are other ways you could fund your stamp duty payment. You could use savings or take out a personal loan with a lower interest rate.

Lastly, you should consider the impact if house prices fall. If you’ve added stamp duty to your mortgage and house prices drop, you could end up in negative equity (owing more on your mortgage than your house is worth).

Each situation is unique, and it’s crucial for you to weigh your options carefully. You should consider seeking advice from a mortgage adviser or financial planner to ensure you’re making the best financial decision for your circumstances. These professionals can provide you with tailored advice on the advantages and disadvantages of adding stamp duty to your mortgage. It’ll equip you with the knowledge and confidence to make the right move. It may seem like a trivial decision, but it can have long-lasting effects on your financial health.

That being said, every property purchase comes with its own set of challenges and considerations. Understanding the intricacies of adding stamp duty to a mortgage is just one part of the equation. Armed with the right knowledge, you’ll be better equipped to navigate through them.

Is Adding Stamp Duty to Your Mortgage a Viable Option?

Now that we’ve enlightened how stamp duty can influence your property purchase and mortgage, it’s time to delve a little deeper. Got all those pros and cons in your mind? Good. Let’s explore whether adding stamp duty to your mortgage is a viable option.

Of course, who doesn’t love the idea of avoiding an immediate financial burden? Adding stamp duty to your mortgage certainly offers temporary relief from a hefty cash outflow. On top of that, this decision could provide you with that much needed extra liquidity for any revamps or renovations your new home might require. It also allows for better budgeting and forward planning, taking into account your monthly outgoings.

But let’s flip the coin here. Adding stamp duty to your mortgage isn’t all rainbows and butterflies. Remember, adding extra costs to your mortgage increases your overall debt. As you can imagine, this means inflated interest payments over the life of the loan, resulting in you paying significantly more than the cost of the property alone. Moreover, you’ll also be operating at a higher loan-to-value ratio. This can prove problematic when seeking more favourable mortgage deals in the future. Finally, don’t ignore the elephant in the room – negative equity. If the property market takes a downturn, and you’re left owing more than your house is worth, well, that’s a sticky situation to say the least.

Seeking advice from a seasoned professional should be your next port of call. A mortgage advisor or financial planner will be able to guide you through the fog of property taxes and mortgage subtleties, enabling you to make an informed decision. It’s about weighing it all up.

In the next section, we’ll further shed light on understanding how stamp duty affects first-time buyers and those investing in second homes. So, buckle up! The journey through the world of stamp duty and its impact on mortgage decisions isn’t quite over.


Adding stamp duty to your mortgage can be a double-edged sword. It’s a strategy that might ease your immediate financial burden, yet it’s not without its pitfalls. You’ll be paying more in interest over the life of the loan, and it could impact your ability to secure favourable mortgage deals down the line.

Remember, every property purchase is unique and what works for one person might not work for another. It’s crucial to get professional advice tailored to your circumstances. Whether you’re a first-time buyer or investing in a second home, understanding the ins and outs of stamp duty can make a significant difference to your financial planning.

In the end, the decision to add stamp duty to your mortgage is yours to make. It’s all about balancing the potential benefits against the possible risks. So, do your homework, seek advice, and make an informed decision that suits your financial situation.
