The 5 Most Common Mistakes Property Owners Make When Valuing a Property

If you've ever been involved in selling or buying a property, you know how stressful it can be. The value of your home is not just a number; it is tied to memories, effort, and future plans. Yet, many owners, in their attempt to estimate a property's worth on their own, make mistakes that cost them time, money, and opportunities. At Spitigkonzalez, we see daily how important it is to avoid these mistakes and rely on trustworthy data rather than guesses. In this article, we will explore the 5 most common mistakes owners make and how you can avoid them.

1. Rely on emotion instead of data

The most classic mistake. A house is full of memories: holidays, the child's first steps, summers on the balcony. However, the market does not pay emotional value. When a owner overvalues the property because it means something to them, they lose serious buyers.

Tip: View the property through the buyer's eyes. Use objective criteria and appraisal tools.

2. Compare with the wrong properties

The neighbor sold it for €200,000, so I want the same. A comparison that is often unfair and incorrect. Every property has unique features (year of construction, condition, view, access). If you compare your home with wrong examples, the price you come up with will be wrong.

Tip: Base your estimate on real market data today, with reliable information on prices, areas, and trends.

3. Underestimate small details

Moisture on the wall, an old bathroom, or lack of parking can significantly reduce value. Many owners ignore these elements, considering them insignificant. In reality, the buyer notices them first.

Tip: Do a small check before the evaluation process. Sometimes, small fixes make a big difference in price.

4. Ignore market trends

The real estate market is not static. Prices change depending on the economy, demand in a area, new infrastructure. Many owners insist on last year's prices or what they heard from acquaintances, missing the timing.

Tip: Stay informed about current trends and rely on official data, not rumors.

5. Do not seek professional help

Perhaps the biggest mistake. The idea that I will do it myself often costs a lot. Without specialized knowledge, the chance of falling into traps is high.

Tip: Trust platforms and professionals who know the market. At Spitigkonzalez, for example, we base the evaluation on real data and provide a clear picture without ads and misinformation.
