Probate valuers assess properties with sitting tenants by applying a discount to the open market vacant possession value, reflecting the reduced price a buyer would pay for a property they cannot immediately occupy or redevelop. The size of that discount depends primarily on the type of tenancy in place, the rent being paid relative to market rent, and the tenant’s security of tenure. The sections below address the most common questions executors and solicitors encounter when a tenanted property forms part of a deceased estate.
What discount applies to a property with a sitting tenant for probate?
A sitting tenant discount for probate purposes typically ranges from 10% to 40% of the property’s vacant possession value, though in some cases it can be higher. The discount reflects the fact that a purchaser is acquiring a property subject to an existing occupancy, which restricts their ability to sell, occupy, or redevelop it freely. The exact figure is not fixed by law and must be justified by the specific circumstances of the tenancy.
For properties subject to regulated tenancies under the Rent Act 1977, where the tenant has strong security of tenure and the rent is set well below market levels, discounts at the higher end of the range are common. For assured shorthold tenancies with a short remaining term, the discount is generally modest because vacant possession can be recovered relatively quickly through the standard legal process. The valuer’s role is to assess what a willing buyer would pay in the open market on the date of death, knowing the tenancy terms in full.
How does tenancy type affect the probate valuation figure?
The type of tenancy in place is the single most significant factor in determining the tenanted probate valuation figure. Different tenancy types carry different levels of security for the tenant, different rent structures, and different timescales for recovering possession, all of which directly affect what a buyer would pay.
Regulated tenancies, which predate the Housing Act 1988, offer the strongest tenant protections. Rent is often set at a registered fair rent well below current market levels, and the tenant cannot be removed simply because the landlord wants vacant possession. These properties attract the largest discounts, sometimes exceeding 40%, because the investment proposition is constrained and the pool of buyers is narrow.
Assured tenancies under the Housing Act 1988 offer greater landlord rights but still provide meaningful security to the tenant. The discount applied is typically moderate, reflecting the balance between tenant protection and the landlord’s ability to recover possession on defined grounds.
Assured shorthold tenancies, which are the most common form of modern residential letting, carry the least security for the tenant. Provided the correct notice procedures are followed, possession can generally be recovered at the end of the fixed term or through a Section 21 notice. The discount applied to these properties is usually the smallest of the three types, often in the range of 5% to 15%, depending on how much of the tenancy term remains.
What evidence does a RICS valuer use to justify the tenanted value?
A RICS valuer justifies the tenanted probate valuation by reference to comparable market transactions involving tenanted properties, the specific terms of the tenancy agreement, and the relationship between the passing rent and the current open market rental value. This evidence base is what allows the valuation to withstand scrutiny from HMRC or any interested party.
The valuer will review the tenancy agreement in full to establish the type of tenancy, the rent payable, any rent review provisions, the remaining term, and any break clauses. Where the passing rent is significantly below market rent, this directly supports a larger discount. Where rent is close to market levels and the term is short, the discount is more limited.
Comparable evidence from sales of tenanted investment properties in the same area or property type provides the market context. The valuer will also consider the condition of the property, the tenant’s payment history if available, and any relevant legal factors such as whether a notice to quit has already been served. Every factor that a hypothetical buyer would weigh up in the open market must be reflected in the valuation report.
An RICS Red Book valuation documents this reasoning transparently, producing a report that sets out the methodology, the comparable evidence, and the rationale for the discount applied. This level of documentation is essential for HMRC compliance.
Can HMRC challenge a sitting tenant discount on a probate valuation?
Yes, HMRC can and does challenge sitting tenant discounts on probate valuations, particularly where the discount appears disproportionate to the tenancy type or where the valuation lacks adequate supporting evidence. HMRC’s Shares and Assets Valuation team has the authority to query any figure submitted on the Inheritance Tax account and to request further justification from the valuer.
The most common grounds for challenge are that the discount applied was too generous given the tenancy terms, that the comparable evidence cited does not support the figure, or that the tenancy itself is informal or undocumented and therefore may not bind a purchaser in the same way a formal agreement would. HMRC may also question whether the tenancy was genuine or whether it was created close to the date of death in a way that artificially reduces the estate’s value.
A valuation prepared by a RICS-registered valuer, grounded in documented comparable evidence and compliant with the Red Book standards, is significantly less likely to face a successful challenge. Where the discount is substantial, a well-reasoned report that sets out the legal basis for the tenancy and the market evidence for the reduction is the most effective protection against a dispute.
Should executors wait for vacant possession before instructing a probate valuation?
No. Executors should not wait for vacant possession before instructing a probate valuation. The valuation for Inheritance Tax purposes must reflect the open market value of the property as it stood on the date of death, including any tenancy that was in place at that time. Waiting until the tenancy ends would result in a valuation that does not represent the correct date-of-death position.
Under Section 160 of the Inheritance Tax Act 1984, the relevant value is what the property would have fetched in an open market sale on the date of death, with all its encumbrances. If a tenant was in occupation on that date, the tenancy is part of the asset being valued. Submitting a vacant possession figure when the property was tenanted at death would misrepresent the estate’s value and could expose the executor to HMRC penalties.
The practical implication is that executors should instruct a probate property valuation as promptly as possible after the date of death, providing the valuer with full details of the tenancy. The valuer can then inspect the property, review the tenancy documentation, and produce a compliant report reflecting the tenanted value at the relevant date.
Who should instruct a probate valuer for a tenanted estate property?
The executor or administrator of the estate should instruct the probate valuer, though in practice solicitors handling the probate administration frequently coordinate this on behalf of their clients. Either party can make the referral, and the instruction should come as early as possible in the estate administration process to avoid delays to the Inheritance Tax submission.
For tenanted properties in particular, it is important that the valuer instructed holds RICS registration and has demonstrable experience in valuing investment and tenanted properties for probate purposes. A general estate agent valuation is not sufficient. HMRC increasingly scrutinises probate valuations not prepared by a qualified professional, and for a tenanted property where a discount is being applied, the valuation report must be robust enough to withstand challenge.
Solicitors managing complex estates often prefer to work with a single specialist provider who can handle both the valuation and any associated administration, including house clearance, document retrieval, and property sale arrangements. This reduces the coordination burden on the legal team and ensures consistency across all aspects of the estate.
