Steven,
Welp, since you are not a horse owner or horse person, I promise it will be more headache than you can ever imagine. Plus, 2 acres is way, way too small!
Ready for every species of fly and gnats to invade your property, even if stalls are cleaned 2x a day and manure is hauled away? Depending on the weather in your area, fly season will last from approximately March/April to Oct/Nov. On only 2 acres, your house is close to the barn. Flies will get into your house, no matter what you do.
Speaking of manure, what are you going to do about that? An average horse poops 50 pounds of poo per day. That’s 1,500 pounds of poop, PER HORSE, every single month! Boarding four horses? You’ll get 3 tons (6K lbs) of poop per month! That’s 18,000 pounds of horse poop per horse, per year! Boarding four horses all year long? You’ll get 72,000 pounds, or 36 TONS of horse poop per year in return. All that, on your tiny 2 acre plot. You will not be able to compost it quickly, either. You’ll have a mountain of poop. Haul it away? No idea of the cost, but it’s probably $200-$400 per month, maybe more, to have a dumpster that you dump daily poop into and then it’s hauled away.
On such a small lot, is there hay storage? How many tons can be stored? Is there wood shavings storage? How large? If you don’t have much hay or shavings storage, then hay will have to be delivered every few weeks or months. Same for shavings. Each horse will eat approximately 3 tons of hay per year, and poop it out into 18,000 pounds of manure.
The noise! Are you ready for some hungry or thirsty horse (that your “self care” boarders didn’t feed and water) to be clanking the buckets and banging the stall wall all night? Thinking of sleeping in? Think again. People will show up before 6 am to feed horses and clean stalls.
The people! You’d better have a bullet-proof contract, outlining ever detail and specific. Better lock up every tool, or else they’ll walk away. Better have clear boundaries as to if they can drill holes in your barn walls and mount racks and hangars, or are you the only one to do that? They will destroy your barn if you let them! The people will also be walking all over your yard, knocking on your door and interrupting you, bringing their dogs (unless you specify NO DOGS, and even then, someone will bring their dog), moms will drop off their kids and you’ll be baby sitting. If you are not aware of what can spook a horse or what a horse can get hurt on, if you’re not careful, a person or horse will get hurt or killed on your property and sue you.
Is there a bathroom in the barn? If not, where will people go to the bathroom? Don’t let the people use your horse stalls as a toilet. Rent a porta potty? That will have to be cleaned weekly. Add probably $150+ in monthly expenses. Add more weekly traffic to your property, too.
The hours. 7 days a week, you’ll have people in your hair! From 6 am until 9 pm, all day, every day. Horses are fed 2-4 times per day, every day. Since you have no turnout or pastures, those horses will probably be fed 3-4 or more times per day.
DON’T DO IT!!!
