According to the survey data show that the rate of new apartment sales between 38% -40% is feasible. Office buildings, commercial buildings have different operating rates. Operating rate is too low, some of that investment program costs not considered. Too high, then the poor management. All this shows that too low or too high too risky.
(2) debt income ratio. Net operating income is net income after payment of all costs is the primary source of funds to repay debt. It reflects the ratio of debt obligations borrowers ability to repay loans. As the risk measure related to real estate investment project the probability distribution of possible outcomes, which can be used as probability theory and mathematical statistics, real estate investment risk identification method. Investment results here mainly refers to the return of real estate investment return. The return of the probability distribution of returns is not easy to obtain. Although it is possible for market research, information projects have been developed, using mathematical or statistical methods estimate the distribution obtained, even by statistical test, but the results only in a relative sense, on behalf of the probability distribution of the proposed development project. This is because the differences between the various real estate projects in large, sometimes ten meters away from the location, even if other conditions are the same, return on investment returns, there are very different. The sampling methods and the combination of subjective probability judgments to determine the return on real estate investment rate of return is the actual probability distribution of workers commonly used method.But if a real estate investment return rate of return there are several possible outcomes, each of the possible results of its probability of xi Pi, then the mathematical expectation:If investors expected return on investment for the mathematical results obtained comply with reasonable expectations. In the statistical sense, because the real return on investment in the largest probability of about mathematical expectation. Then the standard deviation to describe the expected results and actual results of the "average" degree of change, it can be used as a measure of risk. Standard deviation the greater the risk the greater the standard deviation of the smaller, less risk. Measured with a standard deviation of the concept of investment risk has the advantage of relatively clear and intuitive, you can borrow a set of sophisticated mathematical theory and statistical methods. To reduce investment risk in the portfolio theory, this measure has good performance. The disadvantage is that the probability of accurate sub-city of Pi is not easy to find. Taking into account the same standard deviation for expectations of different
