Standard valuation works by comparison: find five similar sales, adjust, average. That is adequate for an ordinary apartment in a block of forty. It says very little about a converted mill, a modernist villa on a double plot, a townhouse with a hotel licence, or a finca whose value sits in the land rather than the built square metres.
For properties like these the market price is not something you find. It has to be constructed.
Where the method sits
Silent Sale is a private sales practice. Property is offered off-market — to a selected circle of buyers, without public listing, and without the exposure that costs a property its price while it waits.
That work begins with a figure. An off-market sale is a conversation with few participants, and in a conversation that narrow there is no crowd to correct a wrong number: a price set too high goes unanswered, a price set too low is accepted immediately and quietly. Where comparable sales exist, establishing that figure is routine. Where they do not, it requires a method.
Valor Singular is that method. It is the instrument Silent Sale uses to establish what a property is worth when there is nothing to compare it with — before deciding how, and to whom, it should be offered.
Who it is for
Valor Singular is for owners of property that has no equivalent: singular architecture, an irreplaceable view or position, a plot that could not be assembled today, a documented history or cultural standing, a project that exists nowhere else.
It is for owners whose asset changes value with its use — a building that could become a hotel, an estate that could be divided, land whose worth depends on what may be built on it.
And it is for anyone who cannot answer a simple question: what is this worth, when there is nothing to compare it with?
What the method considers
Alongside what can be measured and compared — surface, plot, condition, legal and planning standing — the method reads what cannot: architectural singularity, history and provenance, previous owners, the view and whether it is protected, privacy, the interiors and the art within them, and the question that decides more than any other, whether the property could be built again today.
It weighs the desire the property commands and the friction that stands against it, and returns a coefficient — the Coeficiente de Singularidad — and from it a figure, expressed as a range with the conditions under which it holds.
A modo de ejemplo, la posición del coeficiente se extrae de su propiedad, no es fija.
Where it stands in relation to regulated valuation
Spanish regulated valuation, governed by Orden ECO/805/2003, recognises four methods: comparison, cost, residual and income capitalisation. Between them they account for everything a property can be measured by. None of them contains a coefficient for singularity, and the regulation itself acknowledges that comparison loses reliability on atypical property, where it calls instead for the reasoned judgement of the valuer.
Valor Singular is built in precisely that space: the four regulated methods establish the measurable base, and the Coeficiente de Singularidad reads what they are not designed to reach.
What singularity looks like
A house where a head of state once stayed. A building that carries the name of an architect who shaped the region. The only penthouse in the tallest residential tower in Europe. A finca whose pine woodland took forty years to reach the height it stands at now, on land where nothing of the kind would be permitted again.
Each of these is a plain fact about a property. None of them appears in a comparison of price per square metre. Each of them changes what the property is worth, and to whom. Valor Singular exists to answer the question that follows: what does it mean in euros?
What may make a property singular
Owners often undervalue what is least replaceable about their property, simply because they have lived with it for years. Mark anything below that applies. There is no wrong answer, and nothing here is required.
- Architecture by a named or notable architect
- A documented history, or a connection to a historic event or figure
- Previous owners of note
- A view that cannot be built out or recreated
- Exceptional natural light, or an orientation that cannot be repeated — a terrace that holds the afternoon sun, rooms that no future building can overshadow
- Privacy — no overlooking neighbours, no passing traffic
- Something that could not be built again today, under current planning rules
- A relationship to its setting: the property belongs where it stands
- Mature trees, woodland, or established gardens that took decades to grow
- Water as part of the setting: sea frontage, a river, a lake
- Water as a resource: a spring, a well, irrigation, or registered water rights
- Interiors, decorative work, antiques or art that form part of the property
- A concept — the property was conceived as a single idea, not assembled over time
- Scarcity: few or nothing comparable comes to market now
- International appeal — the property would be recognised beyond Spain
- Potential to become something else: a hotel, a division, a restoration, a development
This is not a calculator.
Describe the property below. It is read against the method by the advisor who prepares the assessment — by hand, at Silent Sale, with no automated valuation at any stage — and verified before it is sent.
The first assessment is approximate, the data being limited, and it says so plainly. It sets out what carries the value, what stands against it, and what a fuller reading would require.

A first assessment is free.
A full Valor Singular dossier is prepared individually for each property. It requires a conversation, documents, and in most cases a visit: the deeper the information, the closer the figure. The dossier sets out the valuation logic, the price achievable under each scenario, the buyer the property is likely to find, and the route by which it should reach that buyer — publicly, privately, or not at market at all.
Questions
What is Valor Singular?
The valuation method used by Silent Sale for property with no comparable sales. It combines measurable factors — surface, plot, condition, legal standing — with unmeasurable ones — architectural singularity, history, view, privacy — and returns a coefficient and a value range.
Who is it for?
Owners of property that has no equivalent: singular architecture, an irreplaceable position, a plot that could not be assembled today, or an asset whose value depends on its use.
Who prepares the assessment?
It is prepared by the advisor at Silent Sale and verified before it is sent. The method is applied by hand; no automated valuation is used at any stage.
Why does a valuation method belong to a private sales practice?
Because for a property offered off-market, price and placement are one decision. An off-market sale is a conversation with few participants, and a figure that ignores who the buyer could be leaves that conversation without a basis.
How does it differ from a tasación?
Valor Singular is a strategic valuation and positioning assessment, not a formal appraisal, and does not constitute a tasación oficial under ECO/805/2003. Formal valuations are arranged separately through certified partners.
How does Valor Singular relate to Spanish regulated valuation methods?
Spanish regulated valuation, governed by Orden ECO/805/2003, recognises four methods: comparison, cost, residual and income capitalisation. None of them contains a coefficient for singularity, and the regulation itself acknowledges that comparison loses reliability on atypical property, calling instead for the reasoned judgement of the valuer. Valor Singular is built in precisely that space: the four regulated methods establish the measurable base, and the Coeficiente de Singularidad reads what they are not designed to reach.
What does it cost?
A first assessment is free and approximate. A full dossier, prepared individually after a conversation and usually a visit, is a separate engagement.
Which properties count as singular?
A converted mill, a modernist villa on a double plot, a townhouse with a hotel licence, a finca whose value sits in the land, or any property whose history or standing is part of its worth.
This is a strategic valuation and positioning assessment. It is not a formal appraisal and does not constitute a tasación oficial (ECO/805/2003). Formal valuations for banking or legal purposes are arranged separately through certified partners.
