My Realtor, Revi Mendelsohn, helped my get my house; 22 bidders on it, but I really wanted it, and I wasn't an all cash buyer. She was soooooo awesome, I cannot begin to tell you what she put up with, but I can tell you how she handled it ....... brilliantly, as I am in the house!
I paid over asking, but not a huge amount, and that was fine, I knew I was going to have to, and I have made that up since, for sure; but she was so great in dealing with him, and I would contact her if I were you ....
Good luck! I know how hard it is, especially when it is the house you really want!
