Depending upon the conditions that need to be met to make it buildable, possibly all of the people on your list. You need to find out what's 'wrong' with the property. It could be a flood zone, or it won't perc for septic, or any number of other problems. I would think the county building/zoning department would be your first stop. Hopefully, they can explain in plain English what the problem is. It's up to you to research this, and find out everything you can about the property. Unless land is very expensive or rare in the area, I would probably keep looking. Having to jump through legal hoops always scares me.

BTW- 'plat' is the correct term. You were looking at a plat map- have no idea where the term comes from.

Thanks for the response. Land is relatively rare/expensive in the area, so I'm going to try to navigate through this fairly carefully. I'm sure septic/well should not be an issue as all the surrounding are on public sewer/water. And I don't think flooding is an issue, but I'll drive around the land tomorrow to get a better idea. I think my main issue will be public school board, from what I've read local builders can only build subdivisions for 55+ residences, schools are maxed out so they can't build homes for new families.
