I am only looking for land via websites (realtor, zillow, milestone realty, etc) but a good friend of mine recommended loopnet also.
I search everyday, and sometimes I find some pretty good deals outside of what kind of mileage I want to drive to reach them, but my best results are usually setting a 50 mile radius on google maps and picking the towns that fall inside there.
I'll typically look for a minimum of 2ac, and anything larger than that will show up.
Allen county is Scottsville, and one of my friend's dad used to be county judge executive there.
It is a nice area and you can probably find some 2-5 acre listings pretty easily.
It seems like there are more available lately, and they're reasonably priced most of the time.
