The MLS has a function called Realist. Simply ask your agent to pull up the realist tax roll report and on there it will specify how much the note is for (or notes if there were 2 mortgages). If there is no note then the purchase was cash. Also when the property was entered as sold on the MLS the realtor must enter whether the sale was cash or financing and if it was financed whether it was conventional or not. It is a task that will take a realtor about 40 seconds. If you wanna post the address or pm it I can do it for you or any of the realtors on the site here can.
