The purpose of my statement was not to make realtors give up their profession
I didn't really think it was... but I appreciate the add'l response.
Here, in Illinois, we have the interesting back-up that 99% of our transactions are handled by attorneys, and we have a 5-day Attorney review that immediately follows the acceptance of any contract. During that 5 days the attorney will review the contract, and if there's anything that s/he finds that s/he doesn't like... s/he will alter it... the only thing they are not allowed to change is the purchase price.
So a clause, like the one I mentioned, will have been reviewed by an attorney, and validated or modified, and Illinois Realtors are fairly well protected. But if I had not included the language of "Buyer may, at his option..." then I'm relying that the attorney (who might be overworked and working on 40 transactions at once) will pick up on that nuance... better for me to put it in, and trust that he'll look at a hand-added clause.
Additionally, most of the attorneys I work with, are familiar with how I write my contracts, in fact I've already had a discussion, with one of them, about this very thread, and the addition of "Buyer may...at his option...", and he said to me... "I've never had that occur, but it's an excellent way to phrase it".
At least in Illinois, I don't think we're in danger of being considered practicing law by doing so... other states... "Writer beware"... check with your managing brokers.
btw... I welcome the questioning and discussion of real estate matters with "unlicensed buyers and sellers"... and it sounds as though Realty novice may have a legal background, so there might be some validity to his/her statement. But as Magda points out... when it comes down to making the decision... rely on a professional (whether that be a Realtor or Attorney) rather than the interested friend, uncle, parent who "thinks" he knows best, 'cause that's how it worked in 1943 when they bought their last house. Rely on a professional who does this for a living each and every day.
