First-Time Buyer and Second-Time Buyer Mortgage

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

Many mortgage lenders only require one applicant to be a first-time buyer to access certain products or enhanced income multiples. But for stamp duty purposes, you won’t be treated as first-time buyers. You can’t qualify for first-time buyer relief when buying with someone who has owned a property before.

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

You will not qualify for first-time buyer stamp duty relief. The requirement is for all applicants to be first-time buyers with no previous property or land ownership.

If one of you has owned a property before, you will lose your first-time buyer status in terms of stamp duty.

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

Standard rates will apply. As of 1 April 2025, you don’t pay any stamp duty on the first £125,000. You pay 2% on the portion from £125,001 to £250,000, and then you pay 5% on the portion from £250,001 to £925,000. Above that, it’s 10% up until £1.5 million and then 12% on anything over £1.5 million.

Standard rates would apply, because first-time buyer relief will not be available if one of you has bought before [all information correct at the time of recording in December 2025].

How will an existing mortgage or past property ownership affect our borrowing potential?

If your previous mortgage was maintained well, your borrowing potential will mainly depend on standard affordability checks. However, if you keep your current mortgage in the background as a Buy to Let or just as a second home, lenders will factor in those associated costs.

Will affordability be based on both incomes equally? How do lenders view our other commitments?

Affordability is generally based on both applicants’ income and their existing financial commitments will be assessed – whether these are joint or you hold personal loans and credit cards separately. It will all be included in the affordability assessment to calculate the final borrowing amount.

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

The short answer is no. This is not a specialist lending area. Most lenders regularly deal with applications involving first-time buyers and previous property owners, as well.

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

With a sole application for a first-time buyer, the borrowing amount will be based only on their income, which may be lower than on a joint basis. In this case, the property ownership must also be in their sole name.

We can’t have a situation where a first-time buyer buys a property with a mortgage in their name, but they want their partner to be a joint owner. You cannot be a legal owner of a mortgaged property unless you’re also on that mortgage.

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

The size and source of the deposit significantly impact your application, regardless of buyer status. Lenders must verify the source of all funds for anti-money laundering purposes and to confirm that any deposit is genuine and not an undisclosed loan.

A larger deposit reduces your Loan to Value ratio, which improves available interest rates, increases equity, and lowers monthly payments. Smaller deposits like 5% or 10% may still be acceptable through certain mortgage schemes.

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

You may consider a Joint Borrower Sole Proprietor (JBSP) mortgage, where both of you are named on the mortgage and assessed jointly for affordability. However, only the first-time buyer is named on the property title – they’re the sole owners of the property.

The supporting borrower has no ownership right or entitlement to any increase in the property value, despite being fully responsible for the mortgage debt. Many lenders require the supporting borrower to obtain independent legal advice, and some will not allow them to live in the property.

This option can work with a supporting partner, and is typically used by close family members or unmarried couples. It’s worth noting that not all lenders offer JBSP mortgages, and they each have different criteria. Guidance from a mortgage broker is really important here.
