Home Mortgage

I have been looking in the legal paper for Charlotte, NC and noticed that when the loans go into default, they post the amount of mortgage owed and then the tax value of the property. If I were trying to narrow my search, would I mark off any homes where the amount due is more than the tax value? Can one of these properties also be a great deal- how do I know where the bidding begins, is there a way to estimate based off of this information or do I always need to call the attorney who listed the property?? Sorry- I am new to this whole thing and want to make sure that I properly investigate each property I am interested in to minimize my risks. Any help or advice would be appreciated. Thank You!
