Measuring the worth of an expired domain?

Started going for pbns/expired domains, can someone give me some pointers on what I should look out for other than strong rd and a lot of backlinks?

I went through around 10-11mil domains before I found these, definitely took a lot of time. Clean anchor text, mostly to naked URL/brand name. DNS/hosting history clean registered once/dropped once.

Domain 1:
Brandable domain, relevant links and can be used as a money site. (Which I will)

Links: Total of 6 rd.
xbiz.com
kinkly.com
nerdist.com…
