What is a buy as is?
In a buy as is, the property price is agreed upon without considering the exact surface area, meaning that any discrepancies between the actual square footage and the recorded data do not lead to price adjustments. This is common in situations where parties want to avoid complications from differences between official documents (such as the Cadastre or Property Registry) and the physical reality of the property. In regions like the Costa del Sol and the Canary Islands, where the demand for new housing is high, this type of sale simplifies the purchasing process.
Legal meaning of buy as is
The buy as is is regulated by Article 1471 of the Spanish Civil Code. This article states that in the sale of a property at a lump sum price, no price adjustments are made even if the actual surface area differs from what is specified in the contract. The validity of the agreed price does not depend on the exact surface area, underscoring the importance of conducting a detailed inspection before formalizing the sale.
What does “buy as is” mean in a deed?

In a public deed, “buy as is” indicates that the buyer acquires the property in its current condition, and the surface area is not crucial to determine the price or form contractual consent.

This simplifies the transaction and avoids litigation, shifting the risk to the buyer.
Legal implications for buyer and seller
The buyer accepts the property as it is and cannot demand a price reduction or terminate the contract if the surface area is less than recorded. However, the seller remains responsible for hidden defects and contractual breaches. The buyer must rely on the seller’s good faith regarding the absence of hidden defects that may affect the property’s value or habitability.
Differences between buying by buy as is and by unit of measure
The main difference between buy as is and sales by unit of measure lies in how the property price is determined. In a sale by unit of measure, the price is set according to the property’s surface area, and any discrepancy can lead to price adjustments or contract termination.
In a buy as is, the price is fixed and is not adjusted for surface area differences. This modality is common in properties where precise measurements are less relevant, while sales by unit of measure are used when surface area is essential, such as agricultural or commercial land.
