The appellants appealed the current value assessment of a 3.99-acre former school property in Wasaga Beach, assessed at $692,000 for the 2013 and 2014 taxation years.
The appellants argued the 2011 purchase price of $430,000 established the current value.
MPAC argued the sale was akin to a forced sale and that the highest and best use was multi-unit residential development, supporting the higher assessment.
The Assessment Review Board found MPAC's highest and best use analysis speculative, as the property was zoned institutional and no steps had been taken to amend the zoning.
The Board concluded the 2011 sale was the best evidence of current value and reduced the assessment to $430,000.
No equity reduction was applied.
