What are the key differences between estate agents valuations and RICS probate valuations?

The key differences are the intended use, evidential weight, valuation method and reporting standards. An estate agent’s assessment is primarily a market appraisal to guide an asking price and marketing strategy, whereas a RICS probate valuation is prepared to establish a defensible figure for estate administration and, where relevant, inheritance-tax reporting.

Purpose and audience

An estate agent usually considers what buyers might pay in the current market and how the property could be positioned for sale. The appraisal may help an owner or executor decide whether to sell, select an asking price or compare likely marketing strategies. It is generally directed at a prospective seller rather than HMRC, a court or other parties reviewing the estate.

A probate valuation serves a different purpose. Executors need to identify the value of assets at the relevant date so that the estate can be administered correctly. The report may be reviewed by HMRC, beneficiaries, solicitors, accountants or other interested parties. Its content therefore needs to explain how the figure was reached, not simply state an expected selling price.

Methodology and evidence

Estate agent appraisals often draw on local market knowledge, recent comparable sales, current listings, buyer demand and the agent’s view of the property’s saleability. They may also take account of presentation, improvements and the price at which the agent believes marketing could begin. Different agents can produce different figures because they may use different comparables or make different judgements about pricing and demand.

A RICS probate valuation normally follows a more structured process. The surveyor considers relevant comparable evidence, the property’s physical condition, location, accommodation, tenure and any factors that could affect market value. The report should identify the valuation basis, assumptions, limitations and evidence used. If the valuation is retrospective, the surveyor must consider the circumstances and market conditions at the specified valuation date rather than simply applying today’s price.

Sale price versus reportable value

An estate agent may suggest an asking price that is intended to attract interest, create competition or reflect a particular marketing strategy. An asking price is not necessarily the same as the eventual sale price or the property’s formal market value.

A probate valuation is concerned with the value required for the estate’s particular purpose. It may need to reflect the property as it stood at the relevant date, including defects, tenancy arrangements, planning matters or other restrictions. The figure should not be adjusted simply because an executor hopes to achieve a higher sale price later.

Inspection and property information

An estate agent may inspect the property to prepare a market appraisal, but the extent of that inspection can be limited. The agent may rely substantially on information supplied by the owner and may not investigate matters such as title, planning permissions, structural defects or specialist legal restrictions in detail.

A surveyor preparing a probate report will usually record the scope of the inspection and any information that could not be verified. The report may highlight issues requiring further investigation, such as:

• unusual tenure or lease terms;
• occupancy or tenancy arrangements;
• development potential and planning constraints;
• access, rights of way or shared ownership matters;
• condition defects that could affect value; and
• restrictions, abnormal costs or other factors affecting marketability.

This does not mean that a valuation report replaces a building survey, title investigation or legal advice. Each professional addresses a different aspect of the property and estate.

Documentation and scrutiny

An estate agent’s appraisal may be provided as a brief letter, email or marketing proposal. It can be useful evidence of local opinion, but it may not contain the detail needed to demonstrate a valuation methodology to a tax authority or in a dispute.

A probate valuation should be sufficiently documented for another professional to understand the conclusion. Depending on the circumstances, this can include the property description, inspection date, valuation date, comparable evidence, assumptions, photographs, limitations and the valuer’s reasoning. The more complex the property or estate, the more important it is to retain supporting records.

Consequences of relying on the wrong assessment

Using an estate agent appraisal as the sole basis for probate reporting can create difficulties if the figure is not supported by appropriate evidence or does not reflect the required valuation date. An inaccurate value may affect inheritance-tax calculations, distribution between beneficiaries and later accounts of the estate. It can also prompt questions from HMRC or lead to the figures being revisited.

A RICS probate valuation does not remove the executor’s responsibility to provide complete and accurate information. Executors should still disclose relevant details, check whether the report covers all necessary assumptions and obtain advice from the estate’s solicitor or tax adviser where the position is complex. If the property is later sold for materially more or less than the probate figure, the difference should be discussed with the relevant adviser rather than assumed to prove that the original assessment was automatically wrong.

Fees and practical choice

An estate agent appraisal is normally associated with marketing advice, while a formal probate report involves a professional valuation service and its own fee structure. The cheapest assessment is not necessarily suitable for the purpose required. The correct choice depends on whether the figure is being used to plan a sale or to support estate administration and tax reporting.

In practice, an estate agent’s view can be useful as supplementary market information, particularly when considering saleability and likely buyer demand. It should not automatically be treated as a substitute for a properly prepared probate valuation where the estate requires formal, independently reasoned evidence.
