First-Time Buyer and Second-Time Buyer Mortgage

Steven Hargreaves explains how a joint mortgage process works when one person is applying as a first-time buyer and the other has bought before.

Will we be treated as first-time buyers or second-time buyers when applying together?

From both a mortgage and a stamp duty perspective, you will be classed as second-time buyers – because one of the people on that mortgage has already had the benefit of being a first-time buyer. Unfortunately, you do lose that benefit.

But with most mortgages there’s very little difference between a first-time buyer and a second-time buyer scheme.

Lenders class customers as first-time buyers, home movers, remortgages and Buy to Lets. But in essence, the difference between a first-time buyer and a second-time-buyer deal is negligible. They’re often exactly the same and have identical interest rates.

Do we still qualify for first-time buyer benefits like stamp duty relief or other schemes?

Unfortunately, you don’t. Let’s imagine I owned my own house and you were a first-time buyer. If we were buying together, I’ve already had the benefit of zero stamp duty as a first-time buyer, so both of us would be treated as second-time buyers.

There would be stamp duty to pay, unfortunately, and the percentage would be dependent on the price of the property.

How is stamp duty calculated when there is one first-time buyer and one second time buyer?

In my example, you’re the first-time buyer and I’m a second time buyer. If we’re buying a home together, we will both be treated as home movers.

People often think they won’t have to pay stamp duty because the house is under a certain amount of money. But if one person has already had the benefit of being a first-time buyer, you can’t make use of that again.

How will an existing mortgage or past property ownership affect our borrowing potential? Is affordability based on both incomes equally?

With affordability, there isn’t a lot of difference between a first-time buyer and a second-time buyer.

Some lenders do offer higher income multiples for a first-time buyer, but equally some have that for second-time buyers. As a mortgage broker, we would recommend a solution based on what the client is looking to borrow.

How do lenders view our other commitments?

Other commitments are taken into account within a lender’s affordability calculator. Imagine you had a loan with more than six months left on it, at £200 a month. We would multiply that £200 by 12 and deduct that off your income – and then apply the income multipliers.

These days lenders’ income affordability calculators can be more complex than that, but that’s the old way of doing it.

With a couple of lenders, being a first-time buyer has advantages. We’re currently in October 2025 and criteria changes on a weekly basis, but at the moment with TSB, any loans or finance aren’t deducted off your income. That is brilliant from a first-time buyer’s perspective.

It can mean you can borrow more with TSB, because those loans or hire purchase agreements aren’t taken into account.

In most cases, though, a lender would lend exactly the same as for a second-time buyer. So if a first-time buyer is buying with a second-time buyer, your affordability shouldn’t be significantly affected. You should still be able to afford a similar amount.

Are there lenders that specialise in mixed first-time and second-time buyer applications?

There isn’t a lender that specialises in it. All lenders would take this kind of application.

What we’re actually talking about is the affordability. Some will lend more than others, and there can be a massive swing. I was chatting to some clients recently where the difference in borrowing between one lender and another was £140,000.

That’s the benefit of coming to chat to a mortgage broker, because if you need a bit more, we’d go to a different lender. It doesn’t necessarily affect the interest rate, but each lender offers their own affordability calculations – and the differences can be huge.

Should we apply for a mortgage jointly or should the first-time buyer apply alone?

It depends on what you’re buying and whether that first-time buyer can afford it on one income.

If I have my own house and we’re looking to buy together, you would probably assume that we’re buying a home with a higher value property. If the first-time buyer’s income could support that on its own, that’s fine. But if you need my income to buy the property you want, it needs to be a joint application.

Should we choose between joint tenants or tenants in common? What’s the difference for us?

We’re verging into questions for solicitors rather than advisors, but roughly speaking a husband and wife would usually do this as joint tenants. In that case, if one person dies, their share of the property goes to the other owner.

Tenants in common often applies when friends are buying together – to get higher up the housing ladder by teaming up. They would tend to do this as tenants in common. If one person dies, their share of the property goes to their next of kin – whether that be parents, brothers or sisters, rather than the other owner.

How does the size or source of our deposits affect our application when one of us is a first-time buyer?

We could actually delete the word first-time buyer from this – because whether you’re a first-time buyer or second-time buyer, it has exactly the same effect.

The size of the deposit makes a huge difference to the interest rate. When a bank is looking at lending money, they look at risk. A high Loan to Value mortgage of 95% or 99% is very risky for them, because if the customer misses payments and they repossess the property, the chance of them getting their money back is quite slim. Therefore, the interest rate with a high Loan to Value is more expensive.

If you go to a 90% mortgage, i.e. you put a 10% deposit down, the interest rate reduces greatly. If you come down to 85%, 80%, 75%, the interest rate comes down each time.

If you’re buying a house at £100,000 and take a £60,000 mortgage, that’s a 60% Loan to Value. The size of the deposit is so important, whether you’re a first or second-time buyer. The larger the deposit, the less risk to the lender, and the cheaper the interest rate.

The source is very important from an anti-money laundering perspective. Any lender, solicitor or mortgage broker will need to establish where that money’s come from.
If £50,000 has just arrived in your account, we need evidence of where it’s come from.

If it’s a gift from a parent or work or whatever, we’ll want confirmation. In most cases we would want a gifted deposit letter from the donor, explaining that it’s a gift and not a loan. Even if it’s coming from your mother or father, a solicitor may ask for six or 12 months’ bank statements to see a build-up of funds. It’s to make sure there’s no money laundering.

It’s a little bit easier when you’re using equity. If you’ve just sold a house at £100,000 and you had a £60,000 mortgage, you’ve got £40,000 equity to transfer. We don’t need to see proof of that.

Are there alternative ways to structure the purchase to reduce costs?

Yes, and the most obvious one is a Joint Borrower Sole Proprietor mortgage. Let’s say I had a small mortgage on my property, and we’re looking at buying together.

I’m going to sell my property, and if you could almost get a mortgage in your name we could use Joint Borrower Sole Proprietor. The mortgage will be in joint names, but the deeds are just in your name.

The benefit here is that you would have no stamp duty as a first-time buyer. I’ve done this on a number of occasions for clients. There is a trade-off, because in that example, the joint borrower still has to get independent legal advice, so there are additional legal fees for that.

How can a mortgage broker help? Any final thoughts?

If you’re dealing with a decent mortgage broker, they’ll talk to you about everything that we’ve covered here – we’ll chat through it all with you.

We’ll make sure that the rate you’re going for is optimal, whether it’s a Joint Borrower Sole Proprietor, whether you’re paying stamp duty and whether it’s a first-time buyer deal or a second-time buyer deal.

It can be a bit of a minefield. In the past I’ve had a client who has put themselves down as a first-time buyer – but they sold a house a year ago. Once it gets down to the legal side, the solicitor asks if you have ever owned a property. The client says yes and suddenly there’s stamp duty to pay.

You’re always better discussing your circumstances with your advisor in full. Then we can work out the best way of moving forward.
