If your concerned then test it on surrogate site. Create a PBN from it, or rebirth it, then send a link from it to a random site that's somewhere on the second page in the niche you want to use it for.
Make sure you send an anchor text link closely associated with the keyword you typed to find the surrogate site. If the surrogate site's rankings go up for that keyword, say from position 17 to position 14, then it's a strong indicator that it's a good site/domain to get a link from.
A proper test would last a month to see how the rankings stabilize as rankings may go up initially for that keyword and then crash again (toxic link), and the opposite may happen where rankings go down initially and then go up again around the 20-30 day mark. (that's the transition / random documents algorithm working)
