This is a great thread. Lots of good stories here.
I only left the farm twice. The first time was at 19 when I did a hitch in the Navy. Then in my late 20's when I got married, I moved 20 minutes away to live in my wife's house in town. {Blountstown Fl, Small Town USA} 11 years ago we built on the family farm, and have loved it. Back then I lived across the street from work, but I drove 20 minutes to spend my days on the farm before going into work in the late afternoons. Now I just drive 20 minutes into work.
We don't farm anymore, just a small garden. We have leased out the hayfield for the last three years. Over half of the 200 acres are planted pines, with much of the rest old growth timber. If you want to travel, planted pines are a good way to not have to mow grass. You won't make a ton of money off them, but they do make your taxes lower. We have sold pinestraw for years on our slash pines before they were thinned, and we are selling it for the first time on our longleaf pines next month. It will be enough to pay the land taxes on all the land, if you don't count the house.
Speaking of house, you will want to plan ahead if you want to spend the rest of your life in it. We built a 2 story to save money, and have regretted it. A month can go by without either of us going upstairs for anything. I'm only 53 and do an hour of cardio everyday, but as you get older, it will be more of a pain climbing stairs. And go ahead and make your showers and bathrooms really big, just in case either you or your wife end up in a wheel chair. We added on to our house about five years ago, and made the addition handicap friendly. It is nice not having to worry about your butt knocking the shower door open when you bend over to pick up the soap. And if your wife likes to workout, make sure you have a room for a home gym.
Keeping the house in town sounds like a good idea until you are sure this move is for you. Good luck with whatever you decide to do.
