We've actually thought about that.
However, to do so we would need to get the land rezoned per the 17 / 20 acre (or so) split.
When we bought the house, it came with only around 7 acres. The other payment was for the additional 30 acres.
Right now, looking at slightly over 4 grand to survey the land to submit to the county for rezoning.
If we don't want to build on the other side of the creek, I'm thinking of two options down the road.
1 - Sell the house with the 2 tracts total of around 37 acres.
2 - Sell the house with 17 acres and rezone the the other 20 or so on the other side of the creek and just hold on to it.
Way I see it, that additional 20 acres could mean a good bit for the right buyer with the open land even though on a large hill.
