You have to charge your tenant according to the rates that are going on in your locality. You can't charge him for more than what you deserve. The rent of your house also depends on the locality that you stay; it also depends on the quality of your household. If you are giving them a completely furnished house with Television and Fridge and Air Conditioner, then you can demand for a higher price. When the tenant comes to have a look at your house make sure that you demand something a bit higher than the actual price you are interested in. by doing this if the client bargains you can demand for the actual price that you were looking for in the first place, this is a very common method which is used by mortgaging companies.
