Buy High DA or TF Domain

want to buy a high DA or High TF domain.
After buying i want to forward it to my main site to lift the benefits of its pointing previous backlink.
How I can manage to keep the DA after I own the Domain and where to find it.
Is this method is Useless now ??? Will Google Take it as fresh domain ??

Will Google de-index the previous backlinks ??

Godaddy auction provide many high PR Domain but I need quality PR Domain with good back link portfolio.


Is there someone who could give me suggestion or even provide something?

Check backlinks with 3rd party tools like ahrefs, majestic, moz. You can also check it that domain is still indexed in google. Check web archive. If you want to make 301 it will be good to have backlinks simialar to yours niche if it will be another it doesn't bring you to many value. Expired domains are still good for 301 or buffer sites but they should be good choosen

Better putting the site back to its original and then linking to your site imho.
