Fair value measurement

Hi, below is the scenario for Question Yanong (June 15)
“Yanong uses the revaluation model for its non-current assets. Yanong has several plots of farmland which are unproductive. The company feels that the land would have more value if it were used for residential purposes. There are several potential purchasers for the land but planning permission has not yet been granted for use of the land for residential purposes. However, preliminary enquiries with the regulatory authorities seem to indicate that planning permission may be granted. Additionally, the government has recently indicated that more agricultural land should be used for residential purposes.
Yanong has also been approached to sell the land for commercial development at a higher price than that for
residential purposes.
Yanong would like advice on how to measure the fair value of the land in its financial statements.”

Can you help explain for me whether the Commercial development and the Resident Purpose are 2 different uses or considered as 1 use? I dont understand why we dont consider the Commercial development is the highest and best use of the asset and use the quote price as fair value?

The answer for this does not even consider any of these 2 as the highest and best use as below. The discussion in the whole answer itself seem that Residential use is the highest and best use but then the answer conclude with current use has the highest and best use…..

“If there are multiple types of market participants who would use the asset differently, these alternative scenarios must be considered before concluding on the asset’s highest and best use. It appears that Yanong is not certain about what constitutes the highest and best use and therefore IFRS 13’s presumption that the highest and best use is an asset’s current use appears to be valid at this stage.”
