If you know the address you can find out who has owned it. The town office will have a record. In most cases you can obtain those records online now. There are still a few towns that haven't computerized their info but most have. You can also get the book/page from the town office for the deed and check the county registry for mortgage information such as amount paid for the property. Good luck! Let me know if you need a realtor to help you through the short sale.
