As an valuer registered with RICS and the Dutch NRVT, there are many guidelines and standards that must be met. In the base, valuations focus on the value of property in the existing situation. Currently there are major shifts going on in the valuation world. Standard objects are valued more and more model-based. However, special objects remain customization, with the advice of an valuer playing an increasingly important role. Questions such as 'what is the value if ..' are more and more common. This requires insight into the use of the object to be valued. 

In the first place, the object is valued in the current state and with the current use. For this purpose, comparisons are made, replacement values are calculated and residual values are calculated. Subsequently, special assumptions can be made with regard to another intended use. If this use becomes higher quality or more intensive, then a higher value will follow. If investments are required to allow for different use, these investments must be deducted from the higher value. Such a value estimate is valuable for strategic decisions, but also for sales.

In the past, valuers were always very reluctant to make appraisals based on special assumptions. Because advice is becoming increasingly important when valuing special objects, this will change. The valuer should not only have valuation knowledge, but to make special assumptions the valuer must also have a great deal of knowledge of the use of the object and the market conditions.

NLhave has a lot of knowledge of ports and logistics and is therefore primarily involved in appraisals and harbors as well as on business parks and economic zones. Such locations often have leaseholds, which requires additional specific valuation knowledge. To make a valuation under special conditions, a valuer must have insight into value and potential. In order to do so development perspective is a plus.
