That is the best word in realty.
Know who you feel comfortable with, they have just become a part of the family, you will need some real personal information about you to find exactly what it is that you are looking for, and this doesnt really communicate well with someone you dont really know or trust.
When interviewing, see if their body language tells you they are as excited as you two are, what are their ideas to you, is it in line with what you are thinking?
Look at your Church in the Bulletin, ask your friends & associates at work.
Are they available is what you want to know, that if you see something they set it up immediately on your schedule. that they are calling you with houses ( do those houses match what you told them you were looking for)
Good luck in your first house, I hope it will be a thrill for you!
