Stay away from North Port.
1. Very desolate. A lot of empty homes owned by European investors. Those who live there full time, well, it's questionable at best.
2. Not congested but considers Wal-Mart & Target to be the major developments of the area.... There is little to any professional development.
3. Good schools. Again, this is questionable in North Port. Depends on what you consider good. Many do not consider the school anywhere in SW FL to be good.
4. Sidewalks

Yeah, we've been looking for those up & down SW FL. They don't exist

But septic tanks & well water do.
5. Not much direct access.
6. Definitely can find a home in your price range in North Port. Excessive over inventory.
To be bluntly honest, don't waste your time looking in North Port & further south.
Brandenton is sketchy & you read right about the crime.
There are areas of Sarasota & further north that are suppose to be quite nice. Best of luck researching & I am sure you will find something!!!
Just stay away from things south of Sarasota. It is not worth your time.
