Finding answers is tough sometimes

So here I am with a listing that seems like it is just too good to be true. The property is priced incredibly for the neighborhood, It is a beautiful home with many updates. I have had 34 showings on the property with very little if any negative feedback and have yet to get an offer. I am really shocked by these developments and I am at a crossroad as to what to do next. The sellers have dropped the list price over $20,000 as they are extemely motivated and are looking for answers from me as to why we can't get into contract. The crazy part is I can not give them an honest answer because I don't understand myself. I know that property values are dropping like crazy but this home is priced incredibly for the neighborhood. I have told the sellers that my job is to get people into the batter's box so to speak and I obviously have done that with 34 showings. Problem is, I can't make them buy the house. Has anyone out there had a similiar situation happen to them. I feel like my sellers are frustrated (and so am I) but I don't really know what more I can do. Any suggestions out there from my Active Rain family would be much appreciated. Have a great day everyone and looking forward to some helpful advice!!!
