Wow thanks for all of your responses so far 
I’ve actually lived/worked at a farm in Germany in my younger years so it’s not totally foreign to me; I absolutely loved it; even when we had to get up at the crack of dawn in the winter to get the horses in from the field for lessons, it was the best time of my life.
My husband works on call and spends a lot of spare time at home puttering around the house so he would love to have more projects to do 
I spend a lot of time driving to the boarding barn so it would be nice to have those extra hours back; I live and work in a small city which has a farm communities within a 20 minute drive so the extra time I would spend commuting would be less than the time I spend driving to the boarding barn every week.
I have a couple of reliable house/barn sitters lined up who could step in and “sit” for us if we ever wanted to go on vacation.
We are thinking about either buying an existing horse farm or buying land and building one of those barn homes, where the stalls are at the bottom and the living quarters on top. If we build, we would add an outdoor arena, round pen and two pasture areas.
We are just in the preliminary stages of this process so I wanted to reach out and get some feedback from people who have done it to see if there are any pros and cons that I haven’t already thought about.
I would think that getting utilities and cable can be challenging? I can probably count on low internet speed or no internet at all?[/QUOTE]
Reconsider that home above the stalls.
Not good for insurance purposes, not good for everyday living around horses, where you may just have some injury that makes stairs a bad idea.
At least consider a barn with a home attached, or a home with a barn attached, preferably separated by some kind of sun room, with firewalls.
Houses or apartments in barns have problems with dust, odors, insects and rodents you don’t have if they are clearly separated structures, even if close or attached.
Horses at home will mean you sacrifice horse time for farm chore time.
That is fine with many, gets old for others, that didn’t realize how much the socialization and horse care and training and general information you have at your fingertips in a commercial barn you may miss with horses at home alone, for you and your horses.
I would say, your question can be answered that it is 50/50 which is better, boarding or caring for your horses in your own place.
What you really want out of your horse experience will determine which way you may lean.
The beauty of giving this a try is that, if you don’t overbuild and overspend, you can always sell again later, hopefully at not too much of a loss, or maybe if the horse economy improves, at a small profit.
If you live long enough, you may just have to sell, eventually.
At least while you are there, if you enjoy the lifestyle of caring for horses yourself, you will be happy.
