Hello fellow appraisers, I was hoping to get some help on this topic. I was assigned to appraise a condo unit in a building that's due to be finished next year, according to plans. It's located in a very dense and urbanized city so there are plenty of recent comparable condo sales in very close proximity. The issue is that the subject building has only had 2 sales in the past 2 year which yield very inconsistent sale price per square foot values, and each condo building nearby also appears to have a different sale price per square foot than the next. My suspicion is that this assignment is impossible. Any input would be greatly appreciated.
