How to calculate the value of a house and set the right selling price

How to calculate the value of a house

To calculate the value of a house, it is necessary to analyse the property's characteristics, compare them with similar homes that have recently sold, and consider the level of demand in the area. This information provides an estimate of the property's market value, which serves as the starting point for determining the asking price.

The analysis should assess the property as a whole rather than relying solely on the price per square metre or on listings for similar homes. Market value is determined by a combination of factors and by the level of interest the property is likely to generate among buyers at a specific point in time.

Although there are online tools that provide a quick estimate, these should only be regarded as an initial reference. A more accurate valuation requires interpreting the market and assessing the property as a whole.

What is taken into account when calculating the value of a house?

The main factors considered include:

• The location and level of demand in the area.

• The size of the property and the layout of its living spaces.

• The condition of the property: whether it is move-in ready or requires renovation.

• The orientation, natural light and views.

• Outdoor spaces, such as a terrace, garden, garage or swimming pool.

• The property's energy efficiency and the overall condition of the building.

None of these factors alone determines the value of a property. Two homes with similar characteristics can achieve different prices depending on market demand, current market conditions or the profile of potential buyers. For this reason, a thorough valuation always considers all relevant variables rather than focusing on a single aspect in isolation.

Market value, property valuation and selling price: what are the differences?

These terms are often used interchangeably, but they refer to different concepts.

• Market value is the price a buyer would be willing to pay under current market conditions.

• A property valuation is a professional assessment carried out by a certified valuer, usually for mortgage purposes.

• The selling price is the final amount agreed upon once the marketing and negotiation process has been completed.

Understanding the difference between these concepts is essential to avoid unrealistic expectations when selling a property.

From market value to asking price: how to set a competitive price for your property

Knowing a property's market value is the starting point, but setting the asking price requires analysing demand, competition and current market conditions. The goal is to establish a competitive price that generates interest from the outset without undervaluing the property.

A valuation does not provide a single fixed figure. Instead, it typically establishes a value range that serves as a reference for defining the sales strategy.

From there, the asking price should be adapted to the market context and the property's characteristics. Marketing a home in an area with strong demand and limited supply is very different from selling in a market where many similar properties are competing for buyers.

It is important to remember that market value is not determined by the owner, but by the market itself. In other words, it is based on the price buyers are willing to pay for a property with similar characteristics in a specific location and at a given point in time.

When determining the asking price, it is also important to analyse factors such as:

• The number of comparable properties currently available.

• The level of demand in the area.

• The average time it takes for comparable properties to sell.

• The profile of interested buyers.

• Recent market trends.

All these elements help establish a competitive asking price from the very beginning.

Working with a real estate professional makes it possible to interpret this information more accurately and turn a property valuation into a sales strategy that reflects current market conditions.

The most common mistakes when calculating the value of a house

One of the most common mistakes when valuing a property is relying solely on personal perceptions or unreliable references. Using property listings as the only source of information, allowing emotional attachment to influence the price, or believing that setting a higher price leaves more room for negotiation can make a property harder to sell.

Calculating the value of a house requires decisions based on data rather than expectations alone. These are some of the most common mistakes:

Relying only on property listings

Looking at similar homes advertised on property portals can provide an initial reference, but it does not offer a complete picture of the market.

Property listings show the prices that owners hope to achieve, not the amounts at which properties are ultimately sold. In fact, some homes remain on the market for months because their initial asking price does not reflect current market conditions.

It is also common to receive several valuations with different figures. In these cases, rather than focusing on the highest estimate, it is advisable to analyse the data supporting each valuation and the sales strategy behind it. A higher figure may seem appealing, but it does not necessarily reflect the price the property can realistically achieve under current market conditions.

For this reason, a professional valuation is based not only on property listings, but also on comparable sales, buyer demand and in-depth knowledge of the local market.

Letting emotional attachment influence the property's value

It is perfectly natural for homeowners to value their property differently from potential buyers. After all, it is a place filled with personal memories, where improvements have been made for the family's comfort and where they may have lived for many years.

However, the market does not make decisions from this perspective. Buyers compare different options and prioritise the features that best suit their needs and budget. While some are looking for a move-in-ready home, others prefer a property they can renovate to their own taste. Some prioritise the location, while others value outdoor space or the internal layout.

For this reason, a property's price should reflect the value recognised by the market at that particular time rather than the owner's personal perception. An objective assessment helps balance both perspectives and supports better decision-making.

Believing that a higher asking price leaves room for negotiation

Many homeowners believe that listing their property above its market value will allow them to negotiate later without sacrificing the price they ultimately hope to achieve. However, this strategy does not always produce the desired result.

The first few days after a property is listed usually generate the greatest level of buyer interest. If the initial asking price is clearly above market value, many potential buyers are likely to dismiss the property before even arranging a viewing.

As the weeks go by, the property loses visibility as new listings enter the market, and it may become what is known as an overexposed property. When buyers see that a home has been listed for a long time, some assume there must be an issue with it or that the owner will eventually accept a significant price reduction.

In these situations, successive price reductions do not always restore the initial level of interest and may weaken the seller's negotiating position.

Setting a competitive asking price does not mean selling below market value. It means generating enough interest to attract the right buyers from the very beginning.

Why does a professional property valuation make a difference?

A professional property valuation combines objective data, local market knowledge and experience with comparable transactions to develop a pricing strategy tailored to each property. Beyond calculating a property's value, it helps homeowners make more informed decisions throughout the entire sales process.

Calculating the value of a house involves interpreting much more information than property listings alone can provide. In addition to the property's characteristics, it is essential to understand:

• how demand is evolving,

• which properties are directly competing with it,

• and how buyers are behaving in that particular area.

For this reason, a professional valuation is about much more than assigning a price. It also helps define a realistic marketing strategy, identify opportunities to improve the property's positioning in the market and reduce the risk of unnecessarily extending the selling process.

At Engel & Völkers, this analysis is based on extensive local market knowledge, comparable sales data and broad experience marketing properties across different market segments.

We understand that every homeowner wants to achieve the highest possible value for their property. That is precisely why a thorough valuation and a pricing strategy based on real market data generally deliver better results than setting a price based solely on the expectation of future negotiations.

Frequently asked questions about calculating the value of a house

How can I calculate the value of my house?

You can obtain an estimate by analysing similar properties, the average price per square metre in your area and your property's characteristics. However, for a more accurate valuation, it is advisable to also consider current demand and the sale prices of comparable properties.

What is the difference between market value and the selling price?

Market value is an estimate of the price a property could achieve under current market conditions. The selling price is the final amount agreed upon after negotiations between the buyer and the seller.

Is it advisable to value a property based only on property listings?

No. Property listings show the asking price set by each owner, but not the final sale price. For a more accurate valuation, it is advisable to analyse comparable sales and current market conditions.

What happens if I list my house at too high a price?

An asking price above market value can reduce initial buyer interest, lead to fewer viewings and extend the time the property remains on the market. In some cases, this may require later price reductions to regain buyer interest.

When should I request a professional property valuation?

Whenever you are considering selling your property. A professional valuation helps you understand its market value, define a pricing strategy suited to current market conditions and approach the sale with greater confidence.
