Buying With a Partner Where Only One Is a First-Time Buyer
First-time buyer relief is all-or-nothing on a joint purchase. If one buyer has ever owned property, the entire relief is lost and standard rates apply to the full purchase price.

Key Takeaways
- •FTB relief requires ALL buyers to be first-time buyers. If one is not, the relief is lost entirely.
- •At £350,000, this means paying £7,500 instead of £2,500, losing £5,000 of relief.
- •There is no time limit. Prior ownership 20 years ago is just as disqualifying as ownership last year.
- •Married couples and civil partners are treated as a unit. If either has ever owned, both lose FTB status.
- •Buying solely in the name of the genuine FTB is the main alternative, but requires a solo mortgage.

The All-or-Nothing Rule
First-time buyer SDLT relief is granted to a transaction, not to an individual buyer. When two or more people purchase together, the relief is only available if every single buyer on the transaction qualifies as a first-time buyer. This is sometimes called the all-or-nothing rule.
The logic behind this rule is straightforward: the relief was designed to help those who have never benefited from property ownership. If one buyer in a joint purchase already has or has had property, the household is deemed not to be in the position of a first-time buyer, and the full commercial advantage of the transaction is denied the relief.
Prior ownership at any point in a buyer's life is disqualifying. There is no cooling-off period, no time limit after which the prior ownership becomes irrelevant, and no partial relief proportional to the FTB buyer's share of the purchase.
This rule catches many couples off guard. The genuine first-time buyer in the partnership often feels aggrieved that their status counts for nothing, but the legislation is explicit: it is the transaction that must qualify, not any individual within it. A couple where one person sold a flat ten years ago will pay exactly the same SDLT as a couple where one person sold a flat last month.
No partial relief: If buyer A is a first-time buyer and buyer B is not, buyer A cannot claim 50% of the FTB relief. Either the full relief applies (all FTB) or none of it does (any non-FTB).
How This Affects Your Calculation
The table below shows the financial impact at different purchase prices. The extra cost column shows how much additional SDLT is payable when one buyer is not a FTB.
| Purchase Price | If Both FTB | Standard Rates | Extra Cost |
|---|---|---|---|
| £250,000 | £0 | £2,500 | +£2,500 |
| £350,000 | £2,500 | £7,500 | +£5,000 |
| £450,000 | £7,500 | £12,500 | +£5,000 |
| £500,000 | £10,000 | £15,000 | +£5,000 |
The figures in the table illustrate why this rule causes so much frustration. At £450,000, losing the relief costs an extra £5,000. That is a significant sum in the context of a property purchase, often enough to affect how much buyers can put toward their deposit or renovation costs. The closer the purchase price is to £500,000, the higher the cost of losing the relief.
Worked Example at £350,000
Sam (first-time buyer) and Jo (previously owned a flat, sold 5 years ago) are buying together at £350,000. Because Jo has owned property before, standard rates apply.
| Band | Rate | Taxable Amount | Tax |
|---|---|---|---|
| £0 to £125,000 | 0% | £125,000 | £0 |
| £125,001 to £250,000 | 2% | £125,000 | £2,500 |
| £250,001 to £350,000 | 5% | £100,000 | £5,000 |
| Total SDLT Payable | £7,500 | ||
Sam & Jo pay (standard)
£7,500
If both were FTB
£2,500
They lose £5,000 of relief
Married Couple Rules
HMRC treats spouses and civil partners as a single economic unit for FTB relief purposes. This means that if either spouse or civil partner has previously owned a residential property, even before the marriage or civil partnership, neither can claim first-time buyer relief on a joint purchase.
This rule applies from the date of the marriage or civil partnership. If you were a first-time buyer at the time of exchange but you married a previous property owner before completion, your FTB status is reassessed at the completion date.
Unmarried couples (whether cohabiting or not) are assessed individually on their own ownership history, but only when buying separately. On a joint purchase, all buyers must still qualify regardless of their relationship status.
This is one of the reasons some couples consider delaying the purchase until after any upcoming marriage, though in practice exchanging before the wedding and completing after is a very high-risk strategy. The completion date, not the exchange date, governs FTB status. If any doubt exists, the safest approach is to confirm marital status and both parties' ownership histories with a solicitor before proceeding.
Divorce and separation: If a spouse owned property that was transferred as part of a divorce settlement and they retain no legal or beneficial interest, HMRC may re-examine FTB status. Specialist advice should be taken before relying on this in practice.
Options Available
If one buyer's prior ownership is costing you the FTB relief, consider the following approaches. Each has its own trade-offs and the right answer depends on your mortgage position, the property price, and how much the saving is worth relative to other practical constraints.
Buy solely in the FTB name
If the first-time buyer can obtain a mortgage in their name alone, they can claim the full FTB relief. The non-FTB partner has no legal ownership but may be named on the mortgage as a guarantor. Note: the non-FTB must not be named as a beneficial owner.
Accept standard rates
If a solo mortgage is not possible, standard rates apply. Budget for the higher SDLT cost upfront. The saving on a £350,000 purchase is significant but may not outweigh the practical constraints of a joint mortgage.
Negotiate the purchase price
Reducing the purchase price can partially offset the SDLT cost, though it will not restore the FTB relief itself. Use the standard rate calculator to find the optimal price negotiation target. A reduction of £10,000 to £15,000 can meaningfully close the gap.
Common Mistakes to Watch Out For
Mixed FTB status purchases generate a high rate of SDLT errors, both in terms of overpaying and (more seriously) underpaying. These are the most common problems seen in practice.
Conveyancer files on FTB rates without checking both buyers
Some conveyancers assume FTB status based on what clients tell them without rigorously checking all joint buyers. If the return is filed on FTB rates and one buyer has prior ownership, HMRC can raise an enquiry and assess the unpaid tax plus interest and potentially a penalty. Both buyers must confirm their status in writing to the conveyancer before exchange.
Assuming overseas property does not count
A property bought in France, Portugal, or anywhere else in the world counts as prior ownership for FTB purposes. There is no geographic carve-out. Many couples where one partner has lived and owned abroad make this error.
Buying in joint names to add the non-FTB to the mortgage, then expecting FTB relief
Some buyers ask whether they can have the non-FTB on the mortgage but not on the title. Lenders vary in their policies, but the key point is that FTB status tracks beneficial ownership of the property, not mortgage liability. If the non-FTB is named on the title at all, they are a buyer on the transaction and the relief is gone.
Failing to model the solo purchase option early enough
If the saving is significant, it is worth getting a mortgage-in-principle for the genuine FTB before exchange. Some couples discover a solo mortgage is feasible only after they have already committed to a joint purchase. Modelling both routes early gives you options.
Forum Spotlight: Real Buyer Questions
These questions are drawn from discussions on Reddit r/HousingUK and MoneySavingExpert. Mixed FTB status purchases generate more confusion than almost any other stamp duty scenario. Here are the questions that come up most often.
Someone asked on a UK property forum:
"My girlfriend has never owned. I sold my flat in 2019. We are buying a house for £380,000. Is there any way to reduce our SDLT given that she is a genuine FTB?"
On a joint purchase, no. Because you have previously owned property, neither of you can benefit from FTB relief on this transaction. However, there is one alternative worth exploring: if your girlfriend can qualify for a mortgage in her name only, she could buy as a sole purchaser and would pay FTB rates on the full price. At £380,000 that would mean paying £4,000 instead of £9,000on a joint purchase, a saving of £5,000. You would have no legal interest in the property, which has implications for security of tenure and mortgage affordability. Both of you should speak to a mortgage broker and solicitor before deciding.
Someone asked on a UK property forum:
"We got engaged last month. My fiance owned a flat in the 1990s. We are buying our first home together in three months. Does the engagement affect anything for stamp duty?"
Engagement does not affect SDLT. You are not yet married, so HMRC does not treat you as a single economic unit for FTB purposes. However, if you marry before completion, the position changes and your fiance's prior ownership would then affect your FTB status. If you are buying jointly in any case, the relief is already lost because your fiance has prior ownership. If you were considering buying in your name only to claim FTB relief, make sure completion occurs before any wedding date.
Someone asked on a UK property forum:
"My husband co-signed his parents' mortgage 15 years ago but never had any equity or ownership share. He was removed from the mortgage after two years. Does this count as owning property?"
This depends on the precise legal arrangement at the time. Being a mortgage guarantor with no legal title and no beneficial interest does not constitute property ownership for FTB purposes. However, if he was named on the title deeds as well as the mortgage, that is a different matter and would likely count as prior ownership. The key question is whether he held any legal or beneficial interest in the property. Your conveyancer should review the documentation from the original transaction before filing the SDLT return on FTB rates.
Someone asked on a UK property forum:
"We're buying for £499,000. My partner owned a house years ago. We know we lose FTB relief. But is there any point negotiating below £500,000 for any other stamp duty reason?"
On your facts, no. Because you are already paying standard rates due to mixed FTB status, the £500,000 threshold is irrelevant to your SDLT calculation. The £500,000 ceiling only matters for FTB relief eligibility, which you have already lost. Your SDLT is calculated using standard residential bands regardless of whether the price is £499,000 or £501,000. The meaningful standard rate threshold to be aware of is £925,000, where the 10% band begins.
Frequently Asked Questions
Can I buy in my own name only to keep FTB relief?
Yes, but only if you can obtain a mortgage solely in your name. If you buy alone you are assessed as an individual first-time buyer. Your partner would have no legal ownership of the property but may still be added to the mortgage as a guarantor, provided the lender agrees.
My partner's previous property was sold 10 years ago. Do I still lose relief?
Yes. FTB relief is lost permanently once any joint buyer has previously owned residential property. There is no time limit or cooling-off period. The relief is simply unavailable where any buyer on the transaction has a prior ownership history, however long ago.
We're not married. Does my partner's ownership affect me?
Only if you are buying together. If you purchase solely in your own name you are assessed as an individual first-time buyer, regardless of what your partner has owned. It is only joint purchases that require all buyers to be FTBs.
What counts as owning property?
Legal ownership, beneficial interest, or holding property on trust all count as ownership for FTB purposes. Renting, being named on a mortgage without having any legal or beneficial ownership, or having a charge over a property does not constitute ownership.
