Study On Perfecting Of Real Estate Appraisal Approach

With the integrating of global economy and the development of information thruway, the real estate, which possesses a territory in global market, is internationalized more and more obviously. With joining in WTO, Chinese economy intimately contact with international economy. For the development of real estate is in high direct proportion with economic development, real estate in our country will be influenced by all and even part of the international economy change more and more obviously. As a new industry, real estate appraisal, is less perfect than some foreign developed country either on system, police, code or on study of theory and approaches. Joining in WTO will accelerate the real estate agency in our country to approach the international routine in one hand, on the other hand it will make our agency to face a serious challenge. AS this, the author thinks that enhancing the study of real estate appraisal theory and technique, connecting the qualitative with quantitative and static state with dynamic analysis, are all in favor of increasing the technological content of real estate appraisal and international competitive power in the academic and practical significance. So in this thesis, I studied three appraisal approaches: market data approach -income approach and cost approach, which are in common use by the numbers through aiming at the domestic and overseas actuality and the questions exited in our present appraisal techniques. The contents of this thesis conclude in market data approach based on fuzzy mathematics, income approach based on grayer forecast theory and the quantitative study of buildings' value depreciation modify.(1) Firstly applying the notion of appropinquity in fuzzy mathematics to solve the scientific choice of optional instances. Secondly using synthetical judge to confirm the amendatory coefficient of territorial and separate factor. Lastly applying appropinquity and choosing close principle again to rationally confirm the appraisal result.(2) Anatomising the connote of capitalization rate and arising a view that capitalization rate should be the add of industry fiducial return and opportunity interest and less than industry IRR. Based on real estate havinglong life, it has long return life. So there is a firstly advanced view in this thesis that is to use grayer forecast theory to resolve the net return's forecast of appraisal object. The new technique overcame the defect of other forecast technique such as linear regress and long trend etc.(3) Through taking account of the influences of time and price fluctuant, I mended the old method of discount calculation and used AHP to make the influences quantitative.
