My house is uninhabited all the year round. When I went back this time, I found someone living in it, which was rented out by the property. What should I do according to law! !

According to the property law, the lessee can be required to move out immediately. And ask the property management company to compensate you for your losses. The rent amount cannot be confirmed, but it can be quoted according to the local rent. The lease date can be based on the vacant time of your house. If the property company has any objection, you can ask the property company to provide evidence on its own. At the same time, you can also sue the property company and ask the court to judge the property company to compensate him for his infringement.
