Getting info on all land owners in area. Software or Online?

[Rob Hogue]

Hey there. This is my first post!

I know there are many manual and tedious ways to get a list of all owners and their physical addresses in an area, but I'm wondering what software (paid or free) everyone uses or if there is an excellent online resource to generate these lists. 

So far, I love this website! And you guys are definitely brilliant on your ideas...
