I have both - a farm that sits empty since I travel away for work.
I have a 5th wheel camper and I board; but lease a stall, do my own work, room for supplies, private tack room, even have my 3 cats there (shes loves my *killers*), dedicated paddock large enough to double for a ring, and permission to put up lights /on switches. 2 miles from my home, across the street from morning work, my night job is 3 miles away. I turn my guy out at am, in at pm or out if nights are good. My one stall takes oh...12 minutes complete, hay is a monthly run, takes an hour/12 mi total., pick up feed along the way home from grocery. I ride everyday, long rides, trailer out to 2 local parks 1-5mi, the other 10-mi away. My camper is NO maintainence. I have a gym across the street complete with pool and hot tub...<ahhhh>
My farm is an hour away, literally no work in the area./ I get home for a couple days vacation with the horses each season – and do love it there, but also see that beyond a few days would require work/ less ride time. I raised my girls there and life was busy, had to be well-scheduled to allow ride time, play time, summer swim time, and down-time. Costs? probably cheaper at home in one way, not in another for farm upkeep, taxes, my time (yes, its worth something)…and I tried to not have work be the toll on my family.
Ive faced the decisons -- yes, Id love to be at home, garden, quiet privacy, 85K forest ac's to ride, everything safe in its own place ...but, in weighing the equation of ride or work.......... ride wins. So, its major that after struggling terribly for 8yrs with this choice Ive decided to sell the farm.
Cost? Instead of farm upkeep, Ill have money to buy a nice rig/lq's and do some competitions these upcoming years.
In this great debate, I think each person needs to look at their lives >today< and measure from that, Life changes and so will your horse needs.
