Basic concepts of building valuation

The purpose will determine the method chosen to carry out the appraisal. Here are some reasons why a building appraisal or valuation might be useful:

  • To obtain mortgage financing
  • To determine the market price for a purchase and sale transaction
  • To process inheritance distribution or separation of assets
  • For judicial and administrative matters.

When conducting an appraisal, there are many aspects to consider, including:

  • The state of repair, quality, and age of the building
  • Its location in the municipality
  • Its intended uses and versatility
  • Its occupancy status

There are different methods for valuing and appraising a building depending on its purpose and regulations. These are some of the most common methods:

  • Comparison method. This involves valuing the building in comparison with other properties with similar characteristics.
  • Cost or replacement method. This is based on the building’s construction cost and its depreciation.
  • Income discount method. This is used for buildings that generate income, such as commercial premises or rental housing.
  • Static residual method. This is used for buildings that require comprehensive renovation for their most profitable use.

Valuing a building essentially means assigning it a fair and objective economic value. An appraiser analyzes the property’s condition, location, usage, and the market in which it is situated to calculate its worth.

There are several ways to value a building, and the appraiser selects the most appropriate method based on the type of property and the purpose of the valuation.

The most common methods are:

  • The comparison method, based on the sale prices of similar properties.
  • The cost method, which calculates the cost of rebuilding the property, minus depreciation.
  • The income capitalization method, which estimates value based on the income generated (ideal for rental properties or hotels).

It is advisable whenever you are about to carry out a major transaction—such as buying, selling, or mortgaging the property, contributing its value to a company, or putting it to income-generating use—or simply to get a clear idea of ​​your net worth. It is also recommended if many years have passed since the last valuation and the market has changed significantly.

The appraiser is a specialized professional who inspects the building, gathers all zoning and property registry documentation, analyzes the market, and applies the appropriate methodology to determine its value. Their knowledge and experience in appraisals form the basis of an accurate valuation.

They are valued by combining several factors: location, surface area, condition, use, income generated, zoning status, and market comparables. The aim is to understand the property as a whole and translate that into a reasonable economic value.

Unique buildings (such as landmark hotels, mansions, former convents, etc.) typically lack direct comparables; therefore, more detailed methods are employed, such as potential income studies, cost analyses, and the valuation of unique architectural or historical features. This work is carried out based on expert knowledge of the specific sector associated with the building’s use.

The main difference lies in the fact that buildings with heritage value are assessed not only based on their current use but also on their historical, artistic, or cultural significance. While this can increase their value, it may also restrict how they are utilized or renovated. In contrast, a conventional valuation considers only the property’s value as a real estate asset. Consequently, the complexity involved in the valuation process is a crucial factor; for buildings with heritage value, the appraiser’s experience and expertise are essential.

If the building is leased and generates stable income, the appraiser will take this heavily into account. High occupancy and solid long-term contracts increase the value. Conversely, if there are many vacancies or weak contracts, the estimated value drops because the risk is higher.

The basis may be the same, but the approach changes depending on the objective:

  • For a sale, it helps determine whether the price is fair.
  • For a mortgage, the bank wants to know how much it could recover if it had to foreclose on the loan.
  • For a company balance sheet, the aim is to reflect the asset’s true book value.

That is why the appraiser adapts the report to each specific purpose.

Such situations can significantly alter the valuation. A protected building often commands a higher value due to its unique character, yet this can also entail additional preservation costs or restrictions on renovations. Furthermore, if the property is located in an area slated for rezoning, its development potential could cause the value to skyrocket—or, conversely, require an adjustment to account for uncertainty until the rezoning is confirmed.

The ITE or IEE indicates the building’s actual condition—whether it has structural issues, dampness, deficiencies, etc. A building with favorable reports inspires confidence and maintains or increases its value. Conversely, if there are serious deficiencies, the appraiser will apply a downward adjustment.
