Metrics are just metrics. Good if you want to get an initial grip on the domains, but not sufficient if you do an in-depth check.
What's the RD of those domains? A half decent domain will cost you $300+ these days. A really good domain around $1000.
Anything less than that is high certainty subpar and the metrics will be all around the place, so selling based on TF for example, when your TF changes from 20 to 5 every other day is impossible.
Non spammed backlinks and clean anchors are just a part of the check. What about the history? Were the domains abused in the past?
