We did something similar 2 years ago. We went from a boarding situation in one state to a mini farm (4.8 acres) and 4 stall barn in a totally different part of the country.
We were lucky that the entire property had perimeter fencing and the back 2.5 horse pasture acres were fenced in separating it from the house itself. We did put up some electric fencing allowing us to further divide up that back acreage as needed.
All the reading and advice you get doesn't totally prepare you for the changes in your horse relationship and what it entails having your horse at home.
I remember my first trainer telling me that there is nothing like seeing your horse in your backyard and she was so right. On top of that, we have learned a lot.
Enjoy your new place!
