Google's John Mueller said that using expired domains, and repurposed domains are "SEO-flotsam, index-cruft." John went on to add that search engines have had a lot of practice with dealing with that appropriately."
Flotsam is defined as the wreckage of a ship or its cargo found floating on or washed up by the sea.
This is just a great quote, so I had to share it:
Many expired, repurposed domains are SEO-flotsam, index-cruft, and luckily search engines have had a lot of practice with dealing with that appropriately. Build a new site if you want, don't assume there's old & tasty SEO-juice to lick up just by placing a site on an old domain.

Yes, John went on to add that you can "build a new site if you want," but he said, "don't assume there's old & tasty SEO-juice to lick up just by placing a site on an old domain."
We wrote about this topic a lot, a lot, Google knows when domain names change ownership and Google can remove or keep any signals it wants from the old domain.
