My friend asked me to analyze a project to see if it is worth investing: there is a factory building 10000 square meters for sale, which has been built and used for 10 years. If you buy it, it will include. First of all, look at the location, whether there is obvious room for appreciation, and whether the formalities of the house are ok. Don't give it a hole. After all, it is a big investment. If it's okay. Look at your fortune, you can't put all your eggs in one basket and rent it in an industrial factory. For such a large fund, the risks should be separated and the investment should be dispersed. You should have enough cash flow and it is not easy to get stuck in depth. Just like I do finance, stocks and futures, I will invest separately. You can't just buy one stock, you can't just buy stocks, you can't just do futures.
