You can manage your own home, but always take into consideration that it is a task that requires time and dedication. Your rental house is a business like any other and will take up a good deal of your time.
Besides paying bills and doing the cleaning and maintenance of the property (gardening, swimming pool, air conditioning filters, small repairs, etc), you must advertise it on the market, manage contacts, receive guests, and meet their demands. The advantage is that, besides keeping all the profit, you will have more control over who will be the people using your house. When you outsource this work, the criterion is no longer yours. In the case where there is a more emotional relationship with the property, this can be a major factor.
Hiring a company to manage your home
Many investors choose to hire companies that specialize in managing seasonal properties. These companies charge a percentage on the rental value (around 15%) but, in compensation, take responsibility for advertising, management, maintenance and payment of bills.
If you live far away, this is a highly recommended option.
