To answer that question you must first think about the fact that if you did not decide to rent you certainly would not have any operating costs but neither would you have any income.
Renting an apartment is obviously not cost-free and you have to consider a number of outgoings such as:
Dry rent
Housekeeping and linen supply: these are costs borne by the Guest, varying according to the type or size of the house.
Utility bills
Turning on policy for damage coverage: liability policy, although not mandatory, is strongly recommended; we also require a deposit from guests to cover any damage caused during their stay. This combination offers greater protection and peace of mind to both guests and apartment owners, providing greater security for both parties.
Property Manager Compensation: The amount of the commission varies depending on the proceeds and/or the number of services requested.
Possible promotion on major OTA (Online Travel Agency) platforms: Varies depending on the area and type of promotion,
Certainly you could think of doing it yourself and avoid the cost of the Property Manager, but you must be prepared to put in a lot of your free time and make yourself available at all times to solve any problems.
From this comes the judgment that guests will have of your apartment and will influence the choice of your property by future guests; and even if you were willing to commit your time, it is still not certain that the earnings will be the same as a professional can guarantee you with the experience and channels available to him, so the game may not be worth the candle.
