Pre-Welcome! What town are you from? I have family in East Texas (Winnsboro & Henderson).
Anna is a lot like a lot of small East Texas towns from my experience, but a lot more advantages because of how close to the Dallas area. You'll find most of what you need is available in McKinney, and if it's not, it's only a short distance to Plano/Frisco etc.
And there's lots of other small towns very close with plenty of neat things (Leonard, Pilot Point, Howe, and many more).
There's not any gated communities (unless there's one secretly hidden somewhere). Most of the homes are in the $100k - $140k range. Rentals are widely available. There aren't really apartment complexes in Anna, it's mostly single family homes.
If you're looking on websites for home available, double check the city it's in, it sounds like you're getting results closer to Plano, Frisco, Lewisville, and Dallas.
The best way to get a good feel is to just come visit, and yes I know how far the drive is. (I just drove to Henderson last week and back home in the same day.)
I hope you find what you're looking for, and good luck!
