Contracting property, how to make a profit?

There are similarities with other enterprises. If you can do it well, you will lose it if you can't. The difference is that the property directly faces the owner, who serves the owner within the agreed scope and collects service fees. The owner is satisfied, and there is hope to earn after paying the property fee, but it is not absolute. It depends on how to look at it, how to pay, and how to compensate.
