Should I buy an expired domain that has already been redirected to some other website? Can I use it or redirect it to my own site if I purchase it?

I was going to purchase an expired domain but then I came to know that it has been redirected to some other website. I have two questions:

Can I build a website around this domain if I purchase it? and will the Domain Authority remains the same ?

Can I redirect it to my own site? and will all the Link Juice flow to my site?

If the domain has already been redirected somewhere else and if the redirects were accepted by Google, much of the authority for that domain may now have moved to a new location. In modern times the practice of buying domains and 301 redirecting them for extra link juice, is ineffective unless you are operating under very specific circumstances (and even then it's usually considered black-hat)

Nowadays Google often checks to see if the new content and pages are similar to the old ones. If they're not then quite often the redirect doesn't work for SEO purposes
