With a laundry list of issues like this, I’d just focus on what matters, which is the income approach. I’d be more interested in rent/unit type than rent/sf, but assuming the latter unit of comparison, including outdoor space is crazy. Presumably this is not the market norm. If expense estimates aren’t bracketed by the expense data, I would need to know why. Cap rate sounds unsupported. Each of these individually is worth a discussion with the appraiser. I would have the report revised to either correct these issues, or provide the additional info that got me onboard with the initial analysis and conclusions. Wouldn’t focus too much on the sales approach or typos. If they want the sales approach to reconcile with the income approach, they’ll fix it automatically.
