The backlink profile of a recently-available domain is a double-edged sword. While some expired domains have been well cared for by their previous owners and have high-quality links from reputable websites, some contain quite questionable backlinks. The worst case scenario is that the domain was merely used as a link farm to strengthen a major project in a satellite domain network and has already been penalized by some search engines.
I don’t think that there is a real way to sell your domain fast, you can put it up for sale, depending on domain name, but if there is a fastest way to sell domain name, it’s certainly - having a good enough name, that someone would want to buy. I don’t like .com domain names, but that’s my opinion, instead I prefer Hacks ( I’m from Serbia, therefore most of word in English, in plural ends up with ‘s’, so every word that ends with letter ‘r’ in plural gives you .RS ) so I think that here we have great Hack domain names which would sell fast. Either way, your contact information should be available in WHOIS , so if you have an interesting domain name, every buyer would like to be able to contact you directly.

Flipping domains are similar to flipping houses in real estate: You buy a property with potential, improve it, and then sell quickly for twice the profit (or more). Between 2005 and 2012, internet marketers had been obsessed with flipping domains… and for good reason. Many were successful at buying plain old domain names, spicing them up with keyword-stuffed content, giving them much-needed traffic, and then selling them off to the highest bidder. But in 2017, can this still be a viable online business?

With over 25 million .com domains registered with Google alone, this top-level domain is by far the most popular choice worldwide. According to the domain marketplace Sedo, in 2015 the average sales price for a .com domain name was over £3000. The most expensive publicly traded domain names have been known to fetch eight-figures sums. But don’t quit your day job just yet: such sales are the exception rather than the rule.
The domain name industry is quite similar to the real estate industry in a lot of aspects. There are end users, brokers, consultants and domain flippers or “domainers”. Domain flipping works similarly to buying a house, renovating it (or even sometimes just sitting on it) and then selling it again at a higher price point. The gist of it is: you’re purchasing a domain name and betting it’s worth (or will be worth) more than you paid for it. If you’re right, you get a nice paycheck and move on. Those who make a living out of this just rinse, repeat, and scale.
