Agree with the previous poster that South River High School is generally the more preferred school, but it’s also more expensive to buy a house there than it is to buy one in the Southern cluster. A house with land and acreage zoned to South River (especially if it’s in Davidsonville) will easily cost $1M+.
Southern is still a fine school. It has an extremely tight-knit community—probably the most in the county, and it’s the type of place where everyone looks out for each other, but the area is highly rural and some of the kids have depression from the lack of access to things to do.
I definitely think it’s worth considering—especially for the right house, but scope out the area in depth first and really think about it because it will be a huge change in lifestyle.
