Over the years one thing I hear over and over in conversation with people when they talk about their previous real estate experiences is: "I wish I'd known more about what I was getting in to" or "My agent didn't tell me what I needed to know".
Honestly I don't think that real estate agents really mean to mislead their clients. It's just that many have been in the business for so long and done so many deals they forget not everyone knows what to expect or fully understands what they're being told. They may not explain everything completely because they think you've taken it all in and understand.
I tell all my clients "There's no such thing as a stupid question." And there isn't.

And if you don't know what questions to ask, say to your agent "What questions should I be asking?" Any good agent will be happy to run through the process with you.
