If I wanted to answer this question briefly, I would say: in order to have more money and less problems. But the situation is a little more complicated than that.
Of course, you are also able to sell, utilize, renovate or rent out your property. The real question is rather at what price. How much time and energy does it take to understand real estate market movements? How much nervousness will be involved in choosing the right specialist, and what will you do if you are disappointed? Do you have time for all this? Can you afford to lose millions due to a delay or mistake? The real estate market is complicated. You have to slowly deal with it full-time in order to understand the trends exactly. Selecting and coordinating the right specialist, especially when there are several specialists at the same time, requires almost a whole person. And in the absence of reliable, up-to-date information, decisions related to real estate are often accompanied by anxiety and doubt. Expert support can protect you from these.
