I am a NJ Realtor, but do not service Cherry Hill and I do not have access to Trend MLS. I do have access to several other MLSs throughout NJ. There have been some withdrawals of Foxtons properties in MLSs during the last few days. If this property is vacant, perhaps there is not seller near the area to remove the sign, even if it has been withdrawn. Many Foxtons listings still show as active in MLSs as of this evening.
I would suggest that you contact a local Realtor and let them know of your interest. A local Realtor will be able to track the status of the listing in MLS, research the tax records and arrange either through Foxtons or direct w/ the owner an appt when the property can be shown.
