Buying a landlord’s interest in a long-leased home: higher LTT rates
Long leases and higher LTT rates
Buying a landlord’s interest in a home subject to a qualifying long lease can fall outside the higher-rates LTT rules.
- The buyer must be buying the interest behind the lease.
- More than 21 years must remain on the lease.
- The leaseholder must not be connected with the buyer.

Buying a landlord’s interest in a long-leased home: higher LTT rates

Buying a landlord’s interest in a long-leased home: higher LTT rates
Higher LTT rates may not apply when you buy a landlord’s interest in a home already subject to a long lease. LTT is Wales’s property tax, often called stamp duty.
A tenant’s existence alone is not decisive. To satisfy the test, the lease, the interest being bought and the relationship between the parties must all qualify.
What this rule is about
People often assume that the higher LTT rate applies whenever residential property is bought, regardless of the interest acquired, the lease terms or the parties involved. That is not always right.
A freehold, or another landlord’s interest, may have less practical value where another person holds a long right to occupy the home.
That distinction is reflected in the law. Some purchases are excluded where the buyer acquires the interest that returns after a long lease ends.
This interest is called a reversionary interest. In practical terms, you buy the landlord’s future interest, not the leaseholder’s present right to live there.
What the official source says
Official guidance says that a purchase is not treated as a higher-rates residential property transaction under this rule if all the following facts exist at the end of the effective date.
- The home you buy is subject to a lease.
- You are buying the interest that sits behind that lease.
- The lease has more than 21 years still to run.
- The leaseholder is not connected with you.
For an individual buying a single home, several homes bought in one deal, and buyers that are not individuals, such as companies, the same lease test applies.
Timing is important. In a normal completed purchase, the effective date is usually completion.
An earlier date may apply if a contract has been substantially performed. For example, this can happen where possession is taken or most of the price is paid.
What this means in practice
This is not a special lower rate for landlords. Instead, it is a rule that may take a purchase outside the higher-rates test.
All other LTT rules that apply to your purchase must still be considered.
What determines the answer? Look to the legal documents. A property listing described as “tenanted” does not settle the issue.
- Check whether you are buying the freehold or another landlord’s interest.
- Check that the lease is still in force on the effective date.
- Count the unexpired lease term on that date.
- Check who holds the lease, including any company or trust involved.
- Keep documents that show the lease terms and ownership structure.
If your conveyancer says higher rates apply, ask whether the property is subject to a qualifying long lease and whether the other statutory conditions are met. That answer may change.
How to analyse it
Consider the questions in sequence. Do not begin with the lease length alone.
A lease with more than 21 years left is necessary. On its own, however, it is not enough.
- What exact interest are you buying?
- Is there a lease affecting that interest at the end of the effective date?
- Is the interest you buy reversionary on that lease?
- Does the lease have more than 21 years left to run?
- Who holds the lease?
- Are that person and the buyer connected under the statutory definition?
- Are you buying one home or several in the same transaction?
When several homes are bought, a long-leased home might not qualify as a home for the relevant higher-rates test.
For a company buying one home, the rule can exclude the purchase from the higher-rates rule where every condition is met.
Example
Asha buys the freehold of a flat for £180,000. The flat is let on a lease with 35 years left.
An unrelated leaseholder owns the lease and remains in place when Asha completes. Asha buys the landlord’s interest, which will return to her when the lease ends.
On these facts, the long-lease exception may mean that the purchase is not treated as a higher-rates transaction under this rule.
One changed fact can produce a different result. With only 21 years remaining, the condition is not met: the law requires more than 21 years.
This exception also cannot apply if the leaseholder is connected with Asha.
Why this can be difficult in practice
Although the phrase “subject to a lease” appears straightforward, it is not always straightforward in a property file.
Leases may have been varied, extended, assigned or partly surrendered. The relevant date also matters.
Another frequent trap is connection. Connected-person rules in the Corporation Tax Act apply under the law.
Do not assume an arrangement falls outside those rules merely because the parties are not close relatives.
- A lease extension may change the remaining term.
- A variation may affect what rights the leaseholder has.
- Company ownership can matter when checking connection.
- A trust arrangement may make the true ownership position less clear.
- Completion may not be the effective date if the deal was substantially performed earlier.
Key takeaways
- A long lease can stop higher LTT rates applying to a landlord’s interest.
- More than 21 years must remain on the lease at the relevant time.
- The leaseholder must not be connected with the buyer.

Official guidance
The pages below are the Welsh Revenue Authority’s guidance. Guidance is not law. It sets out how the Welsh Revenue Authority 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. the Welsh Revenue Authority can also change or withdraw guidance, and it may not cover your facts.
Where this is not settled
- Whether an interest is truly reversionary on a lease can depend on the property documents and the rights being transferred.
- The connected-person test can be wider than an ordinary understanding of family or business links.
- The statutory currency notice requested in the brief was not present in the mounted skills, so the current status of the supplied statutory text should be checked before relying on it for a live transaction.
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 lease and any variations
- the number of years left on the lease at the effective date
- the transfer or contract showing what interest is being bought
- details of any relationship between the buyer and leaseholder
- the date of completion and any earlier substantial performance
