The land is indispensable and limited as the foundation of national living that has stronger public nature and social nature than anything else, and the purpose of the laws on real estate price notification and appraisal is to unify the appropriate price formation of land and the land evaluation in a way of contributing to the efficient use of land and the development of national economy. Accordingly, the state has to interfere on the demand and supply of land market directly or indirectly by the land policies of taxes, contribution and others. For this purpose, the land price is in need of finding out consistently in accordance with certain standard fundamentally. Pursuant to such a need, the implemented official land price system had some insufficient system operation in the beginning time of its introduction, however, through the continuous system improvement, the distorted land market has been drastically stabilized, and the role and function of the official land price has been expanded gradually to the private facilitation territory including the information provision, private transaction, financial collateral and others in the land market. This is indicative of having the stabilization of the land market and its predictability as well as he stable land policy and tax policy through the official land price. In addition, there has been substantial accumulation of appeal and case studies related to the remedy of people following the official land price system. However, all systems and operation cannot be completed, and the study on the advanced official land price system has to be the task undertaken by academy, government and industry.
On this matter, this study has surveyed and analyzed comprehensively for the appeal application data for the official land price with Seoul City as the case study area, and based on the result, the improvement plan for the official land price system is presented. Most of all, as a result of survey made on the appeal application data of the official land price, the demand of upward appraisal was three times more for the lots than the demand for downward appraisal in comprehensive terms. For a detail, the land presented for the upward adjustment has been the lots for various zoning clearance project area, including the new town and re-development and others in relative terms, and the land presented for the downward adjustment is relatively more in lots for various taxes, including the property taxes, than other causes of reduction of best use of land, declined in economy and others.
In addition, the following problems were presented on the current official land price system based on the comprehensive analysis of the B1 of the official land price; First, the individual official land price is shown to be too small for its scope of land category(slope) that is worked as determinant cause or too broad of width(range) of the official land price following the land difference. Second, this is the realistic rate of the official land price that is much lower than the price made in the actual land transactions. Third, in calculating the official land price, the application of multiple rate on the land category has too much of variables. And, fourth, there is an issue of dual system of the department that governs the official land price system and the housing notification price system.
As a result of the study, the following is the improvement plan by close analysis of the appeal status and issues for official land price. First, from the land category of land price standard chart and land information system that are important causes in determining the official land price, the slope and land category ratio have to be segmented and narrow down the range of the official land price for the land with similar characteristics to contribute to the appropriateness to the official land price.
Second, the current transaction price made in the actual real estate market at the time of determining the official land price for the standard land has to be applied actively, and upward realizing the individual official land price ultimately that the official land price has to be converted into the system for actual transaction price.
And, lastly, the dual official land price system and housing price system are unified in one agency to manage the land register and building register to contribute to the efficiency in administration and convenience of people.
Nonetheless, this writer does not believe this study is the most fundamental and complete resolution of the official land price system, and in the future it is intended for profound studies by more work done on broader range of area and overseas cases to contribute to the solidification of the official land price system.
