Stamp duty relief for alternative property finance
This stamp duty relief can prevent SDLT being charged twice when a finance provider buys a property, sells it to you, then takes a legal mortgage over it. Paperwork and the order of events matter. A deal that looks similar may not qualify.
What this rule is about
Some property finance is set up through two sales. First, a financial institution buys the property. It then sells the same interest in the property to you.
Without a special rule, both sales could be SDLT transactions. Section 73 is designed to deal with that structure. It can exempt one or both steps, but only where the legal conditions are met.
What the official source says
HMRC’s manual describes the three steps that must form part of the arrangements, and, although HMRC guidance is not law, those steps reflect section 73 of the Finance Act 2003. That is the framework.
- A financial institution buys a major interest in land. This is the first transaction.
- It then sells that interest to you. This is the second transaction.
- You grant the institution a legal mortgage over that interest.
- Only the interest bought may be sold back.
A major interest usually means a freehold or a qualifying leasehold interest. Although a legal mortgage has a specific legal meaning, that meaning differs slightly between England and Northern Ireland, so the relevant jurisdiction must be identified. That distinction matters.
What this means in practice
The two sales do not automatically receive relief just because a lender or finance provider is involved. Each sale has separate tests.
- Relief may exempt the provider’s first purchase if it buys from you.
- It may also be exempt in the further situation set out in section 73(2).
- Relief may exempt the sale from the provider to you.
- For that second exemption, the provider must meet its SDLT duties for the first purchase.
That last point matters. For relief on the sale to you, the provider must deal properly with SDLT on the first transaction, including any tax due on the required value, before that relief can apply. Relief for the sale to you depends on this.
How to analyse it
Start with the documents, not the product name. Calling an arrangement “alternative finance” does not settle the SDLT result.
- Identify who bought the property from the original seller.
- Check that the buyer was a financial institution for the statutory definition.
- Check what interest it bought: freehold, leasehold, or something else.
- Confirm that it sold that same interest to you.
- Read the mortgage deed and check that you granted a legal mortgage to the provider.
- Check the SDLT treatment of the provider’s first purchase.
- Before relying on section 73, check whether the first purchase was already exempt under Schedule 7, because that exemption means section 73 does not apply. If it was, section 73 does not apply.
Example
Illustration: Aisha wants to buy a £250,000 freehold home using this type of arrangement. The finance provider buys the freehold from the seller for £250,000. It then sells the same freehold to Aisha for £250,000, after which Aisha grants it a legal mortgage, completing the sequence required by this type of arrangement.
Those are the basic steps in the rule. If the provider meets the other conditions, section 73 can exempt the relevant transactions. If Aisha grants no legal mortgage, this particular relief does not fit the arrangement.
Why this can be difficult in practice
This is a document-heavy rule. Small differences in the contracts can change the answer. The source does not say that every finance provider, loan, or mortgage arrangement qualifies.
- A commercial label does not prove that the provider is a financial institution.
- A standard mortgage taken by a different lender may not meet the required structure.
- The provider must sell the interest it obtained, not a different interest.
- A failure to deal correctly with the first transaction can affect relief for the second.
- Other SDLT reliefs may not be used alongside this rule in the way parties expect.
Key takeaways
- This relief addresses a specific two-sale finance structure.
- You need a legal mortgage granted to the finance provider.
- Check every contract and the provider’s SDLT treatment of its purchase.

Official guidance
The pages below are HMRC’s guidance. Guidance is not law. It sets out how HMRC reads the legislation, and it is not binding on you, on a tribunal or on a court. Where guidance and the legislation differ, the legislation wins. HMRC can also change or withdraw guidance, and it may not cover your facts.
Where this is not settled
- Whether a provider meets the statutory definition of a financial institution needs checking against the facts and the relevant definition.
- The documents must show that the interest sold back is the interest the provider bought.
- For an older or future-dated transaction, the law in force on its effective date must be checked.
Evidence you would need
This kind of case is decided on the facts of the individual property. These are the records that usually settle it, and the ones an adviser would ask you for.
- The purchase contract between the seller and finance provider
- The sale contract between the finance provider and customer
- The mortgage deed
- Evidence of the provider’s status as a financial institution
- The SDLT return and tax treatment for the provider’s first purchase
