Probate Valuation Guide
How to value an inherited property for probate, IHT, and CGT
Getting the valuation right on an inherited property is one of the most important steps in the probate process. The figure you use affects how much inheritance tax is owed, your capital gains tax position when you sell, and whether HMRC will accept or challenge your figures.
This guide explains the different types of valuation, when each is appropriate, how HMRC checks valuations, and the common mistakes to avoid. If you are looking to sell, our cash offer is based on current market conditions and reflects a fair price for the property as it stands today.

Why It Matters
Why the probate valuation is so important
The probate valuation is not just a formality. It has direct financial consequences for inheritance tax and capital gains tax, and getting it wrong can be costly.
Inheritance tax (IHT)
The probate valuation determines the value of the property within the estate for inheritance tax purposes. If the total estate exceeds the nil-rate band (currently 325,000 pounds, plus the residence nil-rate band of 175,000 pounds if the property passes to direct descendants), inheritance tax is charged at 40 percent on the excess.
An inaccurate valuation can mean paying too much tax if the property is overvalued, or facing a challenge from HMRC if it is undervalued. If HMRC believes the figure is too low, they can instruct the District Valuer to carry out an independent assessment, which can result in additional tax, interest, and in serious cases, penalties.
Capital gains tax (CGT)
The probate valuation becomes your base cost for capital gains tax. When you sell the inherited property, CGT is calculated on the gain between the probate valuation and the sale price, after deducting allowable costs such as legal fees and improvement works carried out after inheritance.
If the probate valuation is set too low, your base cost is lower, which means the taxable gain when you sell is larger and you pay more CGT. There is a direct tension between IHT and CGT: a lower valuation reduces IHT but increases CGT, and vice versa. The correct approach is always to use the genuine open market value at the date of death.
Key point: The valuation must reflect the open market value of the property at the date of death. This is defined as the price the property would reasonably be expected to achieve if sold on the open market at that date, assuming a willing buyer and a willing seller. It is not the price you hope to get, nor the price in a forced sale. It is the realistic market value on that specific date.
Types of Valuation
RICS valuation vs estate agent valuation
There are several ways to value an inherited property. Each has its place, and the right choice depends on the value of the estate and the complexity of the property.
Estate agent valuations
Most estate agents will provide a free market appraisal. Getting two or three estimates from local agents who know the area gives you a range of values based on recent comparable sales. This is sufficient for many estates, particularly those that fall below the inheritance tax threshold. Estate agent valuations are informal opinions, not formal reports, but they provide a practical starting point.
RICS surveyor valuation
A valuation carried out by a Royal Institution of Chartered Surveyors (RICS) registered valuer produces a formal report that carries significant weight with HMRC. The valuer inspects the property, reviews comparable sales data, and provides a written report with their professional opinion of the open market value at the date of death. This typically costs between 250 and 500 pounds for a standard residential property.
HMRC's District Valuer
The District Valuer (part of the Valuation Office Agency) is HMRC's own property valuation service. If HMRC suspects a probate valuation is too low, they will refer the case to the District Valuer for an independent assessment. You do not instruct the District Valuer yourself. Their valuation is used to determine whether additional inheritance tax is owed. You can negotiate with the District Valuer if you disagree with their figure.
Online valuation tools
Automated online valuation tools use algorithms and property data to estimate values. While these can give a rough indication, they do not account for the specific condition of the property, any defects, or features that affect value. They should not be relied upon for probate purposes. HMRC will not accept an automated valuation as the basis for an inheritance tax return.
Multiple valuations approach
For properties close to or above the inheritance tax threshold, the safest approach is to obtain both estate agent opinions and a formal RICS valuation. This gives you a range of evidence to support the figure you report to HMRC. If the estate agent figures and the RICS figure are broadly consistent, you can be confident that your valuation will withstand scrutiny.
Specialist valuations
Some properties require specialist valuation expertise. This includes listed buildings, agricultural properties, properties with development potential, mixed-use properties, or properties with unusual features. A general RICS surveyor may not have the expertise to value these correctly. In such cases, instruct a surveyor with specific experience in that property type to ensure the valuation is accurate and defensible.
HMRC Scrutiny
How HMRC checks probate property valuations
HMRC has sophisticated systems for identifying valuations that appear too low. Understanding how they check helps you prepare a valuation that will stand up to scrutiny.
Automated screening
HMRC uses data from HM Land Registry, the Valuation Office Agency, and other sources to screen inheritance tax returns automatically. Their systems flag cases where the declared property value appears significantly lower than comparable sales in the area. Properties that are sold shortly after the grant of probate for a price materially higher than the probate valuation are also flagged. This automated screening means that even if you are not selected for a detailed review, your figures are being checked against market data.
District Valuer referral
If the automated screening raises concerns, or if HMRC has other reasons to question the valuation, they will refer the case to the District Valuer. The District Valuer may inspect the property (though they often work from desk-based assessments using comparable evidence) and provide their own opinion of the open market value at the date of death. You will be notified of the referral and given the opportunity to provide additional evidence to support your figure.
The negotiation process
If the District Valuer arrives at a higher figure than your original valuation, you are not obliged to accept it. There is a negotiation process where you can present your evidence, including RICS reports, estate agent opinions, photographs of the property's condition, details of comparable sales, and any factors that reduce the property's value. In many cases, a figure is agreed somewhere between the original valuation and the District Valuer's initial assessment. If you cannot reach agreement, the matter can be referred to the First-tier Tribunal (Tax Chamber) for a binding decision.
Sale price comparison
One of the strongest triggers for an HMRC enquiry is when a property is sold for significantly more than the probate valuation within a short period after death. If you value a property at 200,000 pounds for probate and then sell it for 280,000 pounds six months later without carrying out any improvement works, HMRC will want to know why. A genuine increase in market conditions can explain some difference, but a large discrepancy will almost certainly lead to a review. This is another reason why accurate valuation at the outset is so important.
Getting It Right
How to get the right valuation for your inherited property
Follow these steps to ensure your probate valuation is accurate, defensible, and compliant with HMRC requirements.
Get multiple opinions
Obtain at least two or three estate agent market appraisals from local agents who are active in the area. Ask them to provide their opinion in writing, including the comparable properties they used. For estates above or near the inheritance tax threshold, also instruct a RICS surveyor. Having multiple consistent opinions gives you a strong evidence base.
Document the property condition
Take detailed photographs and notes of the property's condition at the date of death. Record any defects, necessary repairs, outdated features, or issues that reduce value. This evidence is invaluable if HMRC later challenges the valuation. If the property needs significant work, photographs showing its true condition at the relevant date can justify a lower figure.
Use the date of death as the valuation date
The valuation must reflect the property's value at the date of death, not the date of the valuation appointment or the date of probate. If the market has moved between the date of death and the date of the valuation, the valuer must adjust their figure to reflect conditions at the earlier date. Make sure your valuer is clear about this requirement.
Mistakes to Avoid
Common probate valuation mistakes
These are the errors we see most frequently. Avoiding them will save you time, money, and stress when dealing with HMRC.
Deliberately undervaluing to reduce IHT
Some people are tempted to understate the property value to reduce inheritance tax. This is risky and potentially illegal. HMRC has access to extensive property data and will identify valuations that are significantly below market level. If they find deliberate undervaluation, you could face penalties of up to 100 percent of the tax underpaid, on top of the additional tax and interest.
Overvaluing to increase the CGT base cost
Conversely, some people inflate the probate valuation to create a higher base cost for capital gains tax, reducing CGT when the property is sold. This results in paying more inheritance tax than necessary and, if HMRC identifies the overvaluation, could lead to questions about your motives. The correct approach is always to use the genuine market value.
Relying on a single informal estimate
Using just one estate agent's opinion, or worse, your own estimate, leaves you vulnerable to challenge. A single valuation provides no range or corroboration. If HMRC's figure differs from yours, you have limited evidence to argue your case. Getting at least two or three professional opinions, ideally including a RICS valuation for higher-value properties, provides much stronger protection.
Not accounting for the property's condition
A common mistake is to value the property as if it were in good condition when it actually needs significant work. Properties inherited from elderly relatives often require updating, repairs, or clearance. These factors reduce the open market value and should be reflected in the valuation. Ensure your valuer sees the property in its actual condition and notes any issues in their report.
Using the wrong valuation date
The valuation date for inheritance tax purposes is the date of death, not the date when you get around to having the property valued or the date probate is granted. Property values can change materially over several months. If you instruct a valuer six months after the death, they must be asked to provide a retrospective valuation reflecting conditions at the date of death, not current conditions.
Forgetting to keep evidence
Even if HMRC does not query the valuation immediately, they can open an enquiry for up to four years (or longer in cases of careless or deliberate inaccuracy). Keep all valuation reports, estate agent letters, photographs, and correspondence safe. If HMRC raises questions years later, you need to be able to demonstrate how you arrived at the figure you used.
