I'm having a few 2nd thoughts. If he says yes, I have to move the horses. I can't afford both. Am I really committed to driving there twice a day? Will I start bugging my husband about moving? Probably and that wasn't the deal:')
I've got to drive to the barn once a day on weekdays (mom does am chores) and twice a day on the weekends. It puts about 60 miles a day on my truck on the weekend. Can be a pain but is worth it. Am very lucky that my best friend lets our horses live there.
My horses have gotten by on one feeding a day for the last 2 and a half years and are doing just fine. Now granted, they are out on good pasture 24/7 and don't REALLY need feeding at all, but I like to see them at least once a day just to make sure that everybody's ok. I just thought I'd throw that comment out there for your consideration.
Is the property already fenced/shelter on it, water/power?
If they're on pasture with a large enough water supply, they can get by with one feeding/visit per day, I think my concern would be if you wanted them there and unattended by anyone all day and night. That's what I'd worry about... theft, mischief by other people, something taking out the fence, predators, injuries...
I know people do keep horses at pasture where no one is, but they assume those risks.
On the other hand, if you ~had~ to go see them every morning or every night to feed, maybe you'd ride more to make it worth the trip :~) It's easier to put off going to the barn if they are at a full care stable and they don't need you.
