I would agree, the buyer does lose leverage. I have just deleted about 4 long paragraphs about why I don’t believe this is a good idea. I read them and deleted them. There is a good analogy someone told me and it is not coming to me because it is late. Your buyers agent should know what you want, and be 100% committed to your well being. Not someone you met at a sellers open house or someone you called because you saw the sign. Ask yourself this… You saw a home, now would that agent support you if you want to lowball the listing? Just my opinion.
