What factors are considered in a probate property valuation?

A probate property valuation is shaped by the interest being valued, the rights attached to the property, how it is occupied or used, and the evidence available to support the assessment. These factors help the valuer distinguish the property’s gross market value from debts, selling costs and other amounts that may affect the estate’s eventual net proceeds.

1. The ownership interest being valued. The valuation must establish whether the deceased owned the property outright or held only a share. A jointly owned property may need to be considered differently depending on the form of ownership and the rights of the surviving owner. A share in a property is not always worth exactly the same proportion of the value of the whole property, particularly where it cannot be sold independently without agreement from another owner.
2. The tenure and remaining lease term. A freehold interest and a leasehold interest are valued on different bases. For a leasehold property, the valuer may review the unexpired lease term, ground rent provisions, service charges, repair obligations and any restrictions on use or transfer. A short or costly lease can affect the value of the interest, even where the building itself is otherwise suitable for occupation.
3. Who occupies the property and on what terms. Vacant possession, occupation by family members and occupation by tenants can produce different valuation outcomes. An existing tenancy may provide an income stream, but it can also limit a purchaser’s ability to occupy or alter the property. The valuer may therefore examine the tenancy agreement, rent being paid, deposit arrangements, notice position and whether the occupation appears to comply with the agreed terms.
4. Any income-producing or mixed-use element. A property used partly for business, letting or another income-generating purpose may require more than a straightforward residential assessment. Separate accommodation, holiday letting, home businesses, garages or other parts producing income can influence how a purchaser views the interest. The valuer may consider rental records, occupancy information and the division between residential and non-residential use, rather than treating every part of the property as ordinary living accommodation.
5. What is included in the property interest. The assessment should identify fixtures that normally remain with the property and distinguish them from movable contents belonging to the estate. Built-in units, fitted equipment and items physically attached to the building may be relevant to the property value, whereas furniture, artwork, vehicles and removable appliances are generally dealt with separately. Clear identification prevents personal possessions from being incorrectly included in the property figure.
6. The quality and completeness of supporting evidence. A valuer may need to verify ownership records, lease documents, tenancy paperwork, rental statements, building insurance details and information about alterations. Missing or inconsistent evidence can lead to assumptions being recorded in the report. For example, uncertainty about a lease obligation or an undocumented ownership share may require the valuer to qualify the assessment or recommend further investigation before the figure is relied upon.
7. The valuation basis and reporting assumptions. Probate work normally requires an open-market assessment: the amount the relevant interest might reasonably have achieved between a willing seller and willing buyer, with both parties properly informed and neither forced to act. This is different from a distressed-sale figure, an estate agent’s asking price or the amount left after repaying a mortgage and paying selling expenses. The valuer should state the basis used, identify significant assumptions and explain any matters that could alter the conclusion.

Mortgages, arrears, probate expenses and estate debts should not usually be deducted from the property’s gross market value itself. They may affect the net value of the estate, but they are separate from the value of the asset being reported. Similarly, an anticipated quick sale should not automatically replace an open-market assessment unless the instruction specifically requires a different basis.

Where the property is jointly owned, occupied under a tenancy, subject to a lease or used for income, the executor should give the valuer complete information at the outset. The final report should make clear which interest has been valued, what documents were considered and which assumptions remain unresolved. That clarity helps the personal representatives use the figure consistently in the probate and inheritance tax paperwork.
