Roseville is a bit Conservative™️ in my experience. Mega churches and people who can't think for themselves. The further east/upriver you go more the white flight/short sighted neighbor you'll have.
The Laguna side of Elk Grove is where it's at for connecting with other Asian families and good public schools. It's not as expensive as Folsom either, and you could buy more quickly.
What matters is not letting your kid falling behind on reading and math skills, these days. And they have a solid chance of keeping up or excelling in any of those school districts, Folsom Cordova being the best among them.
