I am buying an used electric guitar. It is a Fender Stratocaster. What things should i check for so im non getting ripped off? Tell me as much as you can :)

basically, what are the different things to consider when comparing buying two different electric guitars? I’ve been playing my acoustic Guild for about a year and now I want to switch to electric. Any suggestions? Thanks in advance.
