1.What dept at the couthouse do I go to find out who owe back taxes? Can i find this info on the internet?
Yes there is a place to go and its your county assessors web sit and or office, This is a valuable resource for finding out who owns a peticular property you are interested in also. Every county will have different options when it comes to online information, some wont have a web site at all and you will have to go in. All should have some register of backed taxes however hard or easy to access.
A word of advice: Make a friend in said office if you can.
it is the recorder of deeds in my county … all of the information is public regarding back taxes
