What factors should I consider when deciding between an estate agent valuation and a RICS probate valuation for my property?

The right choice depends on the property’s legal circumstances, the level of evidence required, the complexity of the asset and how the valuation will be used. An estate agent’s appraisal is usually a practical sales estimate, whereas a RICS probate valuation is a formal professional assessment designed to withstand scrutiny in an estate administration or tax context.

Consider the legal status of the property. A straightforward freehold home with clear ownership may be relatively easy to assess for marketing purposes. Probate cases can be more complicated where there are several beneficiaries, a surviving joint owner, an unusual form of ownership, restrictions on the title, an unregistered interest or uncertainty about who has authority to sell. These issues do not necessarily determine the value, but they can affect the assumptions made and the evidence needed.

Leasehold properties require additional checks. The remaining term, ground rent, service charges, planned major works, restrictions on subletting and the existence of a share in the freehold can all influence value. An estate agent may identify some of these matters when preparing a sales appraisal, but a formal probate assessment should record relevant information and explain how it has been treated.

Assess the condition and unusual features. An agent’s figure may be based largely on a visual appraisal and comparisons with nearby sales. That can be useful for setting a realistic marketing strategy, but it may not address defects in sufficient detail for a formal valuation. Consider whether the property has structural movement, fire or flood damage, Japanese knotweed, contamination, subsidence history, non-standard construction, significant disrepair or unauthorised alterations.

Other features may also require careful treatment, including an annexe, development potential, agricultural land, shared access, commercial use, a sitting tenant or a property that is difficult to insure or mortgage. Where these factors could materially affect the figure, a RICS-qualified valuer’s inspection and written reasoning are generally more appropriate than relying solely on an informal sales estimate.

Look at the quality of the comparable evidence. A reliable valuation should be supported by genuinely comparable transactions, not simply asking prices for properties currently advertised. Relevant comparisons may need to reflect the same locality, property type, size, condition, tenure and market conditions. If the property is unusual or there are few recent transactions, ask how the valuer has adjusted the evidence and how much professional judgement has been required.

An estate agent with strong local knowledge may provide useful insight into buyer demand, likely competition and the price at which a property could be marketed. That insight is valuable when planning a sale, but it is not equivalent to a formal valuation report. The distinction is particularly important where a figure may later be challenged by beneficiaries, HMRC or other parties connected with the estate.

Check the valuer’s qualifications and terms of engagement. Find out who will carry out the work, whether they are suitably qualified for the property and whether the report follows the relevant RICS valuation standards. The terms should identify the client, the property, the valuation date, the purpose of the report, the basis of value, any assumptions and the intended users.

Also check whether the person giving the opinion has a financial interest in securing the sale. An agent’s appraisal is commonly provided as part of a marketing relationship, so the figure may be connected to advice about winning instructions or attracting sellers. This does not automatically make it unreliable, but it is a factor when deciding whether the opinion is sufficiently independent for probate purposes.

Clarify the basis of value and the assumptions. A probate report should explain what is being valued and on what basis. It may need to address the property’s market value at a particular historic date, especially where the valuation is required following a death. It should also state assumptions about matters such as vacant possession, planning consent, title information, contamination, services and the condition of inaccessible areas.

Do not treat a single figure as meaningful without reading these qualifications. A valuation based on vacant possession may differ from one involving a tenant. Similarly, a property with potential for extension or redevelopment may need analysis of whether that potential is realistic, legally permitted and reflected in comparable transactions.

Consider the report’s evidential standard. Ask whether you need a brief indication, a written marketing opinion or a report that explains the methodology and supporting evidence. A formal probate valuation normally needs to be sufficiently clear for the personal representatives to retain with the estate records and, where relevant, provide to professional advisers or a tax authority. An agent’s verbal estimate or short appraisal may not provide the same audit trail.

The report should ideally contain the property description, inspection details, relevant documents considered, comparable evidence, valuation assumptions, limitations and the valuer’s reasoning. If the valuation is retrospective, ask how historic market evidence will be sourced and how later information will be prevented from influencing the conclusion improperly.

Factor in tax and estate-administration risk. An inaccurate value can affect the figures recorded for the estate and may create further work if the valuation is questioned. An artificially low figure may understate the estate, while an unsupported high figure may create problems when the property is later sold or the estate is reviewed. The appropriate tax treatment depends on the circumstances, so a valuer’s report should not be treated as a substitute for advice from a solicitor or tax adviser.

Compare the practical scope and cost. Obtain written details of what each option includes. Important questions include whether there will be an internal inspection, whether title or lease information will be reviewed, whether defects will be investigated, whether comparable sales will be cited and whether the report can be addressed to the people who need to rely on it. A lower fee is not necessarily better value if the resulting document cannot serve its intended purpose.

For many estates, the most sensible approach is to use the two services for different purposes: obtain a RICS probate valuation where formal evidence is required, then obtain separate estate-agent advice if the property is to be marketed. If the property is simple and the figure is needed only to guide an eventual sale, an agent’s appraisal may be useful. Where there is legal, physical, ownership or tax complexity, the additional formality of a RICS probate valuation is usually the more defensible choice.
