Autumn Cove would be convenient for the commute to Gastonia and the schools are good there, Clover School District.
Clover Schools In addition you are in the county there so you would only pay York County Property Tax.
The Stoneridge Lakes development is in the city limits of Rock Hill and you would pay city and county property taxes. Of course you would have fire protection, city police and garbage pick-up. But Autumn Cove is protected by Bethel VFD one of the best volunteer fire departments in South Carolina and there is a trash collection center nearby. York County Sheriff's Dept has a good response time and they have a satellite location in Lake Wylie.
I was born in Rock Hill and raised there .... in the city downtown ... which is now called Old Town ... but if I had to chose between the area where Stoneridge Lakes is located and Autumn Cove .. it would be Autumn Cove.
