It has become very difficult to buy a commercial estate in this point of time, i think of a very wealthy person a bit a billionaire as it takes very large amount of money to buy a commercial building with running business.As the matter of fact, nobody wants to sale hi profit giving estate in theses days.But i would suggest you to get out of your living room and go the commercial area , there you find plenty of people who are more than willing to you help you with some commission to earn from you and other party.
