One or several valuation approaches may be used for the purpose of attaining a valuation defined by a proper value principle. Three approaches defined and explained within the scope of this framework are the basic approached used in the valuation.

These methods;

  • Market Approach
  • Income Approach
  • Cost Approach

Market approach is principally used (precedent comparison) in the valuation studies of the structures such as residential-purpose housing, villa, etc. and commercial properties such as office, store, shops, etc..  

Use of cost approach is highly useful in the properties like industrial plants. However, points to be taken into consideration in regard to industrial plants are the valuation of machinery, equipment and production line which can be worth above the building and land values. For this reason, variables such as production capacity, market share, available incentives, distance to the raw material and market are taken into consideration as well as taking diffeent items such as land, building, machinery and equipment into account one by one by making cooperation with our experts in different training and expertise disciplines.

It is highly difficult to make the valuation study of the properties in valuation studies of commercial assets yielding money like plaza, shopping malls, A and B class office buildings with market approach. The number of property which can serve as a peer one-to-one for the said assets is generally limited and it cannot be possible to make an alignment with each other in terms of qualification. Therefore, valuation is performed by making cash flow calculations with income method in addition to the research of market sales and rental values in the valuations of properties yielding money. In addition to this, analyzing the demographical and socio-economic structure of the region where commercial properties yielding money are located in a detailed way and examination of technical properties, monthly rental figures, socio-economic environment and occupancy rates of other similar real estates located in this region constitute the basic reference points of the study.

In valuation studies to be performed for Hotel, Resort Hotel, Golf hotel, SPA, Apart Hotel, Motel, Village Resort, Hostel, Entertainment Centers and Marinas, etc. assessed within the scope of touristic facility, income method is used as the basic valuation system. Items such as cost per room and income items, occupancy rates, extra activity incomes and operating costs as well as the regional, physical and technical properties of particularly touristic accommodation facilities are the most important elements taken into consideration.  

In valuation studies of real estates such as Hospital, Policlinic, Community Health Center, Health and Sports Centers, School and Private Teaching Institution for which public or private sector makes investment, it is required to assess the investments made by private sector as properties yielding rent as well as peer sales constituting the market value and to include these into cash flow analyses from this point of view.  

Recreational areas are generally designed for covering the need of province or district, examinations and analyses to be conducted in the valuation study should cover the whole city. In such properties in which research scope is kept broad, it may require to use all valuation methods together. While making the valuation of recreational areas planned onto the lands with broad surface area, valuation of particularly land is important. Besides, many criteria such as location, population of region, addressed age range are the important elements taken into consideration in the valuation analyses.
