There are two options involve in this situation, if we are talking about just one property it will be best if you manage it yourself since you don't have others to attend to, but if it's more than one property then for it to be easy for you it's best you involve competent and trustworthy personal to help you manage them and report to you directly about everything happening, that way you will have time to attend to others without having huge workload on yourself. Altgough most people will choose to do it all by themselves and you see at the end of the day they start complaining that they are stressed out from much work instead of making things easier for themselves by putting some of the business in a trustworthy person care.
