A property can be worth one figure to a hopeful buyer, another to a lender, and something rather different to HMRC. That is not the housing market being deliberately mysterious, although it does have a flair for drama. This guide to property valuation types explains which valuation you may need, what each one is designed to do, and where a valuation ends and a survey begins.
For buyers, the key point is simple: a valuation is evidence for a specific decision, not a crystal ball or a detailed health check for the building. Choosing the right one means you can proceed, renegotiate or walk away with clearer grounds than a hunch formed during a five-minute viewing.
Why the purpose changes the value
A valuation is a professional opinion of value at a stated date, prepared for an identified purpose. A RICS Registered Valuer considers comparable sales, the property’s size, layout, condition, tenure, location and any factors that affect saleability. In South East London, that can include anything from lease length and service charges to the premium attached to a particularly useful rail connection.
The valuer does not simply average nearby asking prices. Asking prices are aspirations. Sold prices are evidence, but they also need interpreting: was the sale recent, was the property comparable, and did it have a loft conversion, a long garden or a very enthusiastic estate agent?
The valuation date matters too. A probate valuation may be required as at the date of death, while a purchase valuation reflects the market at the inspection date. Same flat, different date, potentially different answer.
The main property valuation types
Market valuation for a private purchase or sale
A market valuation estimates the price a property should achieve if it were properly marketed, with a willing buyer and willing seller, after a reasonable period of exposure. It is commonly used when buyers want an independent view before committing, particularly where the agreed price feels ambitious or the property is unusual.
This can be useful for period houses, converted flats, properties with an annexe, or homes where comparable evidence is thin. It can also add useful perspective after a survey has identified defects. A roof repair, damp issue or short lease does not automatically reduce a price pound for pound, but it may affect what a prudent buyer would pay.
A market valuation is not a building survey. It will not give you a room-by-room diagnosis of defects, estimated repair priorities or a detailed condition assessment. If the building itself is part of your concern, arrange the appropriate RICS Level 2 Home Survey or RICS Level 3 Building Survey alongside it.
Mortgage valuation
A mortgage valuation is commissioned by the lender, not by you. Its central question is whether the property provides suitable security for the loan. It may be a brief inspection, desktop assessment or automated calculation, depending on the lender and property.
This is the source of one of property’s less charming misunderstandings: a lender’s valuation is not a survey, even if you have paid a fee towards it. The lender may decide the home is adequate security while missing issues that matter very much to you, such as ageing electrics, roof defects or damp behind fitted furniture.
If the mortgage valuation comes in below the agreed purchase price, you have a down valuation. That can be inconvenient, but it is useful information. You may need a larger deposit, a revised loan, a price renegotiation or, occasionally, a frank rethink of the purchase.
Probate valuation
A probate valuation establishes the market value of a property forming part of an estate, normally at the date of death. The figure may be used for inheritance tax reporting and for administering the estate, so it needs to be well evidenced and professionally prepared.
It is not based on what the family hopes the property will sell for after a quick repaint and a heroic garden clear-out. The valuer considers the property and market conditions as they stood at the relevant date. If a later sale price differs, that does not automatically mean the probate valuation was wrong, but clear supporting evidence is vital.
Shared ownership and Help to Buy valuations
Shared ownership valuations are often needed when buying additional shares, known as staircasing, or selling a shared ownership home. The lease or housing provider will usually set specific requirements, including that the valuation is carried out by a RICS Registered Valuer and has a limited validity period.
The valuation generally reflects 100 per cent of the property’s open-market value before your percentage share is calculated. It is worth checking the housing provider’s instructions before booking, as a perfectly sound report can still be unsuitable if it does not follow their required format. Admin, like mould, is best dealt with early.
Help to Buy equity loan redemptions have also historically required a RICS valuation. Schemes and procedures can change, so always confirm the current requirements with the relevant administrator before instructing a valuer.
Capital gains tax and other tax valuations
A tax valuation may be needed when a property has been let out, inherited, gifted, transferred between connected parties or used for more than one purpose. Capital gains tax calculations can depend on the property’s value at a particular historic date, rather than its value today.
These instructions need care. The valuer may need documents, dates of ownership, details of alterations and an understanding of the interest being valued. For example, the value of a share in a property may not simply be half the full market value. Tax advice itself should come from an accountant or tax adviser, while the valuation provides the property evidence they need.
Valuations for matrimonial, legal and financial matters
A formal valuation can support divorce proceedings, trust matters, estate planning, loan security, court-related disputes or private agreements between co-owners. Independence is particularly important here. A clear report sets out the basis of value, assumptions, comparable evidence and reasoning, giving all parties a defensible starting point.
Where the valuation may be relied upon in legal proceedings, say so at the outset. The scope, reporting requirements and inspection arrangements may need to reflect that intended use.
A guide to property valuation types versus surveys
A valuation asks, “What is this property worth for this purpose?” A survey asks, “What condition is this property in, and what could it cost or mean to put right?” They overlap, but they are not substitutes.
For a conventional flat or house in apparently reasonable condition, a RICS Level 2 Home Survey is often the sensible buyer choice. It flags significant problems and risks without turning the report into a Victorian novel. For older, altered, extended or visibly worn properties, a RICS Level 3 Building Survey gives a more detailed assessment.
The strongest buying decision often uses both strands of evidence. A survey tells you whether the building has expensive stories to tell; a valuation helps you judge whether the agreed price still makes sense once you have heard them.
What a RICS valuation report should make clear
A professional valuation should be readable, not mystical. It should identify the property and interest being valued, such as freehold or leasehold, state the valuation date and purpose, explain the basis of value, and give the valuer’s opinion with supporting rationale.
It will also record assumptions and limitations. If the valuer has not tested services, inspected concealed areas or verified planning permissions, that should be clear. These are not loopholes. They define what has and has not been assessed, so you know where further checks are needed.
For leasehold homes, expect attention to the remaining lease term, ground rent, service charges and material restrictions where information is available. A handsome flat with a dwindling lease can be less charming to lenders and future buyers than the photos suggest.
How buyers can choose the right valuation
Start with the decision you need to make. If you are worried about paying too much, ask for an independent market valuation. If you are relying on a lender’s mortgage valuation, treat it as the lender’s check, then consider a survey for your own protection. If your situation involves probate, shared ownership, tax or a legal matter, specify that purpose before the instruction is agreed.
Provide useful documents early: the sales particulars, leasehold information, floorplans, planning details, tenancy information where relevant, and any documents setting out scheme requirements. Better information produces a more tailored report and reduces last-minute back-and-forth.
Finally, do not wait for a valuation to grant permission to ask sensible questions. If a figure is lower than expected, ask what comparable evidence was used, what assumptions were made and whether a material fact has been overlooked. Clear insights and simple guidance are part of the service, not an optional extra.
Buying a home will never be entirely free of uncertainty. The right valuation does not remove every risk, but it replaces guesswork with an informed, professionally supported decision – which is a far better companion than blind optimism on completion day.
