Liz, I do not know your circumstances but, i well guess maybe you are in need of attention is sort of way. Whether you have just been through a divource or just broke up with another? We all sometimes come to a point in life where we feel alittle lonely especially when our kids don't call on us until they need something? Or maybe you want to just make some changes to make things a little more exciting. Nevertheless, you are ingaging in an area that can be a bombshell waiting to explode. My advise is to ask him straight up if he really loves you, he should refer you to another agent.
There are many smooth talkers in this industry. Remember, realtors have the same reputation that car sells men have and I believe that to be at least 50% correct. The market is very slow as you know and this can be away for some agents to catch the bait and reel them in. Since, this is not his home, he certainly does not have the investment to loose as you do. At the end he won't care one way or the other what he has done to you. If you have children to keep a roof over head, again you will need to be extra cautious on what you decide.
Remember, if something goes wrong, you will have to come to terms with your own decision.
