You can "own it" without "advertising it". I took a quick look at your profile. Friendly suggestion...you might want to go a little lighter on being a newbie. Clients are looking for someone with more knowledge than they have about selling their home. You ALREADY have that unless they have a real estate license, too! You aren't as inexperienced as you might think!
You have lots of great responses to your specific questions!
You have a ready answer for the other questions you might not know the answer to - "I'll get back to you on that after I've done a little research"!
