The Biggest Mistakes Salespeople Make (and How to Avoid Them)

Setting the bar too high and making adjustments too late

The most costly mistake is setting an asking price based on hope rather than on numbers. The property attracts the most attention in the first two weeks; if that attention isn’t converted into viewings, the listing will drop down in the search results.

Lowering the price after three months actually works against you. Buyers see the history and conclude that there’s something wrong with the property. It’s better to be competitive from day one and let the market do its work.

Accept a poor presentation

Photos taken with a phone, a cluttered living room, a floor plan that doesn’t match—it happens more often than you think, and it costs you money right away. Buyers filter listings online, and anyone who gets weeded out that way will never come back.

A professional photographer, an accurate NEN measurement, and a well-designed brochure are not luxuries but basic requirements. They cost a fraction of what you stand to lose if you fail to make a good first impression.

Concealing Defects

As a seller, you have a duty to disclose any defects of which you are aware and that interfere with the normal use of the property. Failing to disclose such defects can lead to disputes after the transfer and, in the worst case, to liability.

It is much wiser to identify known defects in advance and, if desired, include a structural report. This builds trust, prevents negotiations after the fact, and almost always results in a smoother process.

Letting Emotion Determine the Negotiation

Your home is the place where you’ve lived for years. When a buyer makes comments about the kitchen from 2004, it feels personal, but that’s just part of the game. If you let yourself get carried away, you’ll close doors that would be better left open.

That’s why we negotiate on your behalf. We maintain a professional distance, understand the arguments, and know when an offer is serious and when it’s just an opening move. You make the decision; we handle the negotiations. In practice, this results in both a better price and a smoother sales process.
