A friend is doing real estate industry, he now works in invest japan. I heard that he was working at invest Japan company at first, think he is very fierce. Because invest Japan is a large Real Estate Company, in the industry is very famous, so the competition is very fierce, can enter the invest Japan must have spent a lot of effort. But friends are also very good, so can have this achievement is a reason. I want to buy a house recently, would like to ask a friend in real estate aspects of things, who is also more convenient. And whether it is to buy a house or consulting, real estate information, friends will help me a lot.
