I'm going to choose an experienced realtor over a family friend
Did you not like the job your friend did?
Yes, I had a negative experience with the friend being totally incompetent
That's great you gave your friend a chance, but you should always take things to a professional. I hope you learned your lesson to not take trust and friendship over experience, because you got screwed over and might do it again if you kept consulting your friend.
I need to get my expertise on house value appraised.
Well I hope this new realtor will help you out more than your friend did, even though I'm sure he tried his best.
