Can First Time Buyers borrow extra money on a mortgage for renovations?

It can get quite confusing if you don’t understand the logistics of how a deposit and a mortgage works against a property purchase. First Time Buyers looking to buy their first property often want to get a new bathroom or new kitchen. Or, they fall in love with the property but all the decor needs changing, or they need to do a loft conversion.

Let’s say, you’re buying a property for £200,000. You might wonder if you can get a mortgage for £230,000, giving you £30,000 to carry out the renovations. But generally in that scenario, lenders will say no.

The reason is that you can’t get a mortgage for more than 95% of what you’re paying for the property. Lenders won’t allow that. But if you have a 15% deposit you were planning to put down, a better way to do it is to reduce that deposit contribution: that 15% might go down to 5%.

Then, the money you were going to put towards the property as a deposit is instead used to renovate the property.

How much can I borrow extra on my mortgage for renovations as a First Time Buyer? What would the minimum deposit be?

The minimum deposit for buying your first home is generally 5%, at the time we’re recording in January 2025.

If you’ve only got a 5% deposit, it would be really difficult for you to use any funds to renovate the property.

Like Neezam said, if you’ve got more than a 5% deposit, perhaps 10% or 15%, you could use some of that towards the renovations, bringing it down to that minimum of 5%.

Can you borrow more than the purchase price to fund renovations?

Generally, that is not something you can do. When you buy a property, your deposit and the mortgage combined cannot be more than the purchase price or the property value, whichever is lower.

For example, if you are buying a house for £200k, you cannot ask the lender for £220k just so you have an extra £20k to spend on a new kitchen or an extension. If you are planning renovations, you normally need to have separate savings or cash aside to pay for those. For most first-time buyers or people upsizing, you cannot borrow extra on the mortgage to fund renovations when you buy the property.

How do lenders assess whether to lend extra for property improvements?

This depends on when you are asking to borrow the extra money. If you are asking at the point of buying the property, the majority of lenders will not take planned improvements into account. They will base the mortgage on what the property is worth today, not what it might be after the work is done.

If you are looking to borrow more after you have owned the property for a while, the lender will look at how much your home is worth and how much you still owe on the mortgage. They will look at whether you are able to afford the higher payments and what the money is being used for. In effect, they will be looking at a full affordability assessment.

The lender will be checking things like your credit score and creditworthiness as well. They will also ensure you do not exceed a certain percentage of the property value. With a lot of lenders, that usually sits somewhere between 80% and 90%, and sometimes more.

What types of renovations can you include in your mortgage borrowing?

There is no real fixed list, but people commonly borrow extra for things like a new kitchen, a new bathroom, replacing windows, or rewiring their home. You could also install a new boiler, or take on something much bigger like an extension or a loft conversion.

The important thing is that the bank or building society you are applying with is checking that you are able to afford and sustain the repayments going forward.

They do have a duty to check what the money is for, and it needs to fit a purpose they are comfortable with. For example, if you are asking for £50k to do just a downstairs toilet, there might be questions around whether you are borrowing more than you need.

Home renovations cover a broad umbrella, and lenders will want to sense-check the project. You might occasionally be asked to provide builders’ quotes and plans, especially if you are borrowing a significant amount against the property valuation.

Whether you are making cosmetic updates or tackling bigger renovation projects, there are often options to borrow more. This works as long as it fits affordability, meets lender criteria, and your total mortgage borrowing does not exceed roughly 80% to 90% of the property’s current valuation.

Is it better to borrow extra on your mortgage or take a separate loan for renovations?

There are lots of pros and cons when you are deciding whether to remortgage to raise extra money for renovations or take out a personal loan with a bank. There are a few options available to you, but the answer depends on your own circumstances, the loan options you qualify for, and the interest rates you are looking at.

Your goals also play a part. Someone might have the goal of keeping payments to an absolute minimum, in which case a remortgage may be more suitable because you are able to stretch that borrowing out over a much longer term.

However, the downside is that you may end up paying a lot more interest back in the long term. You are also securing additional borrowing against your home, which puts your home at risk if you fall behind. A personal loan is usually unsecured, so you do not have that same level of risk.

Ultimately, it is about getting advice and speaking to an adviser like us. We’re able to help you understand what those options look like, lay out the pros and cons, and make sure it is clear and meets your preferences and plans.

Can you remortgage to raise funds for home improvements?

Yes, you’re able to remortgage to raise funds for home improvements, and in our experience, it is one of the most common reasons people remortgage. If your home has increased in value or you have paid down some of your mortgage, you may be able to borrow extra to carry out renovations.

This additional borrowing could fund a new kitchen, a fresh lick of paint, or an extension to your entire downstairs. Ultimately, the lender will look at how much your home is worth, how much you want to borrow, and whether you are able to afford the monthly payments.

Lenders need to ensure they are happy lending to you, and that the extra borrowing will not put you in a financially difficult position. They will look at your income and financial backing to validate the additional borrowing, ensuring you meet their affordability checks.

Every lender looks at these situations a little differently, meaning there is no black and white answer as to what the right option is for you. A conversation with an adviser allows us to ask the right questions, understand your circumstances, and review your priorities and budget to guide you through your options.

If you are planning to buy a property that needs work, or if you are thinking about improving your current home, it is worth getting advice early. This helps you understand your options clearly and avoid nasty surprises down the line.

What documents will a mortgage advisor need to see for me to be able to borrow more on my mortgage for a renovation as a First Time Buyer?

You will need to have prepared the standard documents that most banks and building societies request when assessing your affordability and deciding whether to lend to you. You need photo ID and proof of income. If you’re employed, usually that’s the latest three months’ payslips. If you have annual bonuses, commission or overtime, they might want to see a P60 or additional payslips.

They’ll also want to see your latest three months’ bank statements to assess your everyday spending and bills. They also use those to verify if you’ve got any loans or credit cards you’re paying off.

A credit report is very helpful. When we talk to clients, we don’t necessarily have any of those documents before the call, but we’ll leave the client with a clear understanding of what we need to get them an Agreement in Principle, which would be the next step.

If you’re self-employed, it depends on how you’re set up. We often need the latest two years’ tax returns or tax calculation summaries, which you’ll get from HMRC when you submit your self-assessment. There’s also another document called a tax year overview.

If you’re a limited company director, lenders might also want to see your company accounts showing your turnover, net profit and profit and loss breakdown. We talk people through those documents specifically based on their circumstances, but having those prepared will put you on the front foot.

Speak To An Adviser

Should I use a special type of mortgage broker as a First Time Buyer if I’m looking to borrow more on my mortgage to renovate my property?

It definitely helps to use a mortgage broker that works a lot with First Time Buyers. We have a lot of experience in that area.

We understand what challenges you might face and what you might experience throughout the journey. For anyone looking to buy their first home, especially if it’s a house needing a bit of work, a mortgage advisor will help you through each step.

Buying your first home is a daunting process, and you need to know what this particular property could mean for you. It might have a certain problem and be selling really cheap. We can’t necessarily advise, but we can give you the benefit of our experience.

Can I borrow more on my Buy to Let mortgage to renovate?

If you’re a First Time Buyer and you plan to buy a property not to live in, but to let out, it’s not impossible to get a mortgage – but your options will be very limited.

Most Buy to Let lenders want you to already own a property that you live in, so that limits your options. In terms of borrowing more, it works in exactly the same way. Again, if you want funds to renovate the property, it’s just a case of reducing that deposit down.

The challenge here is that most Buy to Let mortgages require you to put a 20% or 25% deposit down as a minimum. So you may not have the room to put less down for a Buy to Let mortgage.

If that is something you’re looking at, speak to an advisor. We could help you understand your options. There are also a lot of other things to factor in if you’re looking at a First Time Buyer Buy to Let mortgage.

What are the pros and cons of borrowing extra money on my mortgage to renovate?

The biggest negative is that as you’re reducing your deposit, you’re likely to qualify for a less competitive interest rate. It’s not a given, but generally interest rates are dictated by the size of the deposit.

The more you can put down, the more competitive mortgage products you’ll get. So the downside to borrowing extra is you have a bigger mortgage, and you could be hit with a higher interest rate as well.

It could be costing you a lot more in interest and monthly payments than if you weren’t renovating a property.

The pros with borrowing extra is that it could increase the property value long term. Renovating generally adds value to the property. It might not have an immediate impact, but you could qualify for better rates in the future. You’re almost taking a hit now to potentially benefit later.

How much will my monthly repayments rise if I borrow extra?

Everyone wants to know, of course, how much it will cost each month to borrow more. Unfortunately the answer to that question is just dependent on too many factors. There’s no set amount. It’s not £100 for every £10,000 you borrow, or anything like that.

It depends on how much you’re borrowing and what the mortgage term is. If you have a longer mortgage term of 35 or 40 years, the payments will increase less than on a shorter term of 10 or 15 years. It depends on the interest rate you’re paying as well, of course, and on the lender you’re approaching. Things will also vary based on your situation, your credit score, income and outgoings.

The only way to really find out is to pick up the phone and speak to an advisor. We would normally help our clients understand this in our first ‘discovery’ call. If you wanted to know how much your monthly payments would increase if you borrowed more, that’s something we can answer on the phone once we understand your circumstances and the interest rates.

How can a mortgage broker help here? Have you got anything else to add?

Seek out a mortgage broker that specialises in helping First Time Buyers. They can share with you – like we have – the pros and cons of borrowing that little bit more. We would compare the costs of renovating and not renovating in terms of mortgage borrowing.

We can also help you plan for your new property purchase, even if you’re just starting to look for properties. We’ll explain what documents are required and what you need to consider.

As we say on a lot of these podcasts, preparation is key for mortgage success. There are lots of things a mortgage broker can help with, but in particular understanding what it’s going to cost to borrow the extra to renovate the property and the pros and cons of doing that.
