I have rented my property in secunderabad to a tenant based on a 11 month rental lease agreement. The tenant informed me after 6 months that they have built a new house and they will be moving to that premises. Based on that they requested me to deduct the 3 month advance given to me at the begining of the lease period.Now it has been more than 3 months and the tenant is overstaying without paying rent. He is also not vacating the house as promised. What are the options i have??
