Several options are available to you if you wish to resell your property.  First of all, you can turn to the real estate agency that originally sold you the property. They will be the best qualified to advise you and carry out an objective evaluation of the property.  If you made your purchase through a property developer, the latter may have a service to manage resales.   Finally, if you choose not to go through a real estate agency, you can take care of the resale of your property yourself.
