@FundamentAli,
First,why does every tom,dick and whoever want to ursurp the roles of valuers.........aaarrrggghhhh clearly we are a failed state!!!
Having looked at your scenario Funda...,i would like to totally disagree with you.
Here are the basic basic definitions to help you differentiate Market Value from Insurance Value.
Market Value is the estimated amount for which an asset should exchange on the date of appraisal between a willing buyer and a willing seller at an arm’s length transaction after proper marketing wherein each of the parties had acted knowledgeably,prudently and without compulsion.
Insurance Value is the estimated replacement or reproduction cost assigned to a property to provide protection against risks such as fire,floods,theft etc. It is arrived at through the gross replacement cost approach.
The gross replacement cost of a building is the estimated cost of erecting the building or a modern substitute having the same gross built up area as that existing at prices current at the relevant date.
This figure would include professional fees,any irrecoverable value added tax and any other associated expenses directly related to the construction of the building,such as foreign exchange movement and exposure for imported components (if any). However,insurance value does not include the cost of land and is only concerned with the improvements thereon.
Having considered the above definitions let me go ahead to water down your scenario.
A house in Kahawa Sukari which cost 30 Million to put up is wonderful,magnificent!!! We are talking about 10,000 Sq feet (929 Sq Metres) worth of construction using a gross replacement cost of Ksh3,000 per sq ft. No developer would put up such a development and sell it for less than 45 Million factoring in Land and his profits. Consequently,no valuer worth his/her salt would value such a house at a market value of Kshs 15.0 M as you put it. Clearly the market comparable would be the 45.0 M.
Substitute the above with Kileleshwa and you still come to the same conclusion.
Hope i have shed more light and put to rest this issue which no one in this forum seemed to have a clear explanation.
