How Much Is My House Worth? How to Value Your Property Realistically (and Avoid Disappointment)
Before putting a property on the market, the big question always arises: “So… how much is my home really worth?”
However, a realistic valuation is much more than comparing your house with what the neighbour is asking — or with the amount you would like to receive.
A solid valuation:
• Speeds up the sale
• Increases the number of potential buyers
• Avoids price reductions later
• Sets the right expectations from day one
Here is what you need to know to understand the real value of your property.
1. Professional Valuation: Based on Data, Not Guesswork
Contrary to what many people think, the value of a property is not determined “by eye”. It requires technical analysis and real market data, such as:
• Actual transactions of comparable properties in the area
• Market trends at that moment
• Condition and characteristics of the home
• Supply and demand locally
• Layout, usable area, extras, and energy certification
A professional valuer takes these and other factors into account to define a well-supported and realistic estimate — one that reflects the market and not only the emotional expectations of the owner.
2. What Influences the Value of Your Home
Every property is unique, but there are factors that heavily influence market value — and many owners overlook them.
Location
One of the biggest value drivers. Access to schools, shops, transport, services, quality of the neighbourhood — all of these have major impact on price.
Condition and Maintenance
A well-maintained home is worth more than one that needs work. Here, elements such as:
• Wear and tear on floors, walls and ceilings
• Quality and condition of windows
• Renovation status of kitchen and bathrooms
• Electrical and plumbing systems
And something many sellers overlook:
• Small improvements can influence the energy rating.
-Replacing windows, improving insulation, upgrading to LED lighting, or installing more efficient equipment can improve the EPC rating — and this increases market value in the eyes of buyers.
Condition of Existing Equipment
If the home includes:
• Air conditioning
• Central heating
• Water heater
• Built-in appliances
• Solar panels
The state and age of these systems also matter. A property with modern and efficient equipment is worth more because it represents lower future costs for buyers.
Sunlight, Views and Orientation
They may seem like details, but they significantly impact the living experience — and therefore the price.
3. The Mistake of Comparing with the Neighbour’s Asking Price
It’s a common habit, but often misleading:
“The apartment next door is listed at X, so mine is worth the same.”
There are two problems with that:
❌ 1. The asking price is not the sale price
What we see on online portals is only the intention of sale — not what the buyer actually paid.
Only the deed confirms:
• The final agreed price
• Whether there was negotiation
• Whether the price dropped (and by how much)
Comparing property values using online listings is like comparing salaries based on what someone is asking in a job application — we only see what they want, not what they will receive.
❌ 2. Two flats in the same building can have very different values
A small change in:
• Renovation date
• Equipment condition
• Sun exposure
• View
• Layout
• Usable area
• Parking
• Storage room
• Energy rating
• Floor level
• Quality of finishes
• Noise levels
…can easily create differences of 10%, 15% or even more in market value.
4.Pricing Above Market Value: A Common Risk
Setting the price too high may feel like “It doesn’t hurt to try”, but the costs are real:
• The property stays longer on the market
• Fewer viewings
• Fewer qualified buyers
• Less visibility online
• Eventually justifies price reductions
Studies show that over-priced properties can take twice as long to sell — even after price cuts.
A price aligned with the market, on the other hand:
• Generates more interest
• Attracts faster offers
• Creates room for negotiation on equal terms
5. How to Understand the Real Value of Your Property
If you want a realistic idea before speaking to a professional, you can compare similar properties — BUT with objective criteria.
When comparing, always check:
✔ Total and usable area
A T3 with 15m² more usable space is not the same property.
✔ Construction year and actual condition
Age and wear matter — even within the same building.
✔ Exact location
Same town does not mean same reality — values can change from one street to the next.
✔ Energy rating
Better efficiency = lower bills = higher value.
✔ Presence or absence of:
• Lift
• Parking
• Storage room
• Unobstructed views
• Balcony or terrace
• Included equipment
• Recent upgrades (new AC, windows, renovation, etc.)
✔ Actual sales in the area
More important than asking prices → is what similar homes actually sold for.
✔ Average time on the market:
If similar properties have been online for months, they may simply be overpriced.
If many similar listings are reducing prices, the market is signalling a correction.
Conclusion:
A realistic valuation does not mean selling below what your home is worth — it means:
• Selling strategically
• With aligned expectations
• With a better chance of serious and quick offers
The market defines the value, and the better we understand it, the better the results.
