I am in the market to buy a website. I would like to browse a list of websites that are for sale or up for auction. Are there any good services for this?
If you're looking to purchase both a domain name, and the hosting to put the website online, I'd advise purchasing them from separate companies (personal preference) unless you find a really good deal for both and have read multiple reviews on the quality of their hosting/customer service.
A good place to check out for your domain name first would be GoDaddy or 123reg, as although I personally wouldn't say they're that great for hosting, they do some pretty good deals on domain names and you can find a wide range of extensions available too.
For hosting however, the choices range far and wide. I don't personally know the reputation of hosting companies over there in the USA, but there's one in the UK called TSOHost that I'd recommend - my websites always seem to be up, and if I do have a query they always answer me within a few hours.
All three of the previous companies I've stated provide you the option of using WordPress and other types of plugins if you're interested in getting a website built fast without having to do much of the back-end coding.
In the case of wanting to buy an already established website, Flippa is probably your best bet.
