Yes that type of livestock fencing in the picture with a hot wire running along the top (keeps them from leaning on it) works well for a friend of mine . She lives on a very busy highway, no problems. I also use it for my paddock.
One thing you want to keep in mind, and that is that for the size area you have, with any rain/wet weather, the ground will be chewed up by the horses hooves. Don't know if you have a "leech field" with the septic tank, but if you do, don't put them there.
You could also use portable electric paddock fencing (we use it on trail rides for overnights) to utilize the other areas temporarily during the day when you are home.
Will you have enough room for hay storage? Since you will probably have to hay year round, that will really factor in to get a good price.
Good luck to you. :)
