The short answer to this is yes, as the domain will most likely have a good age and links which will increase the ability to rank quickly in the search engines. However it certainly pays to fully research the background of the domain before purchasing as the domains previous occupants may have used it for spamming. It’s also good to find out what type of site occupied the domain before and keep the content of the new site in a similar or relevant industry as this information will help you to keep most of the inbound links the from the previous site. There are several online tools that can help you to demine if the domain has had any bad history, the whois.domaintools.com/ site might reveal some good information on the previous site as well as using www.archive.org to find out what type of content the previous site had. In ninety nine percent of cases you will most likely benefit from buying an old or expired domain as well as the points made above it will also have a reduced or none existent sandbox effect.
