About to make an offer on a condo and looking over the standard contract with my realtor is a clause that says realtor will be paid 3% (no problem) but if the seller does not pay this I (buyer) am on the hook for said fee. It's the standard language, but it appears that all the seller has to do is utter the word "no" then my realtor turns around to me and now I have to cut a check for the 3%. I don't think I should take this risk from the seller - that's my realtor's risk to take. Am I worrying about this too much?
