29 According to Mr Sorensen an allowance in the sum of $1,470,750 should be made for selling costs, legal costs and marketing, whereas Mr Wicks says that $2,766,125 should be allowed. The major difference here being that Mr Wicks says that an amount of $1,100,000 should be allowed for marketing and the sales office whereas Mr Sorensen says a total of $120,000 should be allowed. In this regard I am inclined to accept the evidence of Mr Sorensen who consulted with real estate agents who are experienced in marketing developments of the kind anticipated for this particular site. I nevertheless believe that the amount he has allowed would not be sufficient given the more than two years sale period.
30 In relation to the rate of sale input Mr Wicks contends that the proposed lots would probably sell at a rate of 6 - 7 lots per month whereas Mr Sorensen contends that a rate of 8.1 (average) lots per month would be achieved. Whilst this does not seem to be a large difference I understand that a difference of 1 lot per month could equate to a difference in land value of about $1,000,000, an indication of the sensitivity of the model. As I have no way of conclusively determining which of these two figures is correct, for the purposes of the exercise I assume that a sale rate somewhere between the two is likely.
