Advice on towns by Richmond vacant lands?

Hello, I’m looking to be moving the family Texas. My sister and her children are in Richmond why I chose the county I did.

I’m looking for close to 1 acres or better prefer electric water and sewage ready.

Needville and Beasley was recommended I would start off putting a doublewide and eventually build a house. My children are homeschooled I could probably do money without getting a mortgage.

Words of mouth or any kinds of agents who could advise comment or message.

If someone looking to possible get rid of partially the property to I could pay.

Has to be ok for modular, or mobile house.

Advice on doing it or towns would be great serious buyer.
