I think that if she showed you the house the best thing to do is let her write the offer. If you have no confidence in her ability to handle the transaction should it go to escrow, that could be a problem. Usually inexperience won’t cause an escrow to outright fail when buyer and seller have had a meeting of the minds.You have an escrow company and the seller’s agent and other parties trying to make it work too. Just keep a close eye on all the terms as they get written and negotiated.
