I highly recommend you start with Mirna at Ajijic Rentals. They have a large bank of properties, and they are rental agents and property managers. We rent our house out through them, and use them as property managers for the house, for both our protection and the protection of our tenants, as we are not in town when we rent our house out. This way, all bills can be paid within the rental amount, and everyone knows exactly what is and is not included. Mirna knows her properties well, has excellent relationships with the property owners, and listens to the tenants' needs.
