Boarding a friend's horse, what's fair to charge?
So I know this all heavily depends on the area, but to give perspective, board in our town is anywhere from $300-$400 for full board. Boarding is also a very scarce thing. Low end that doesn't have riding arena, just strictly a barn and pasture, with hay and bedding provided, and them feeding and turning out, is around $300-$350. The one facility that I know of that charges near $400 has almost no turn out space, your horse is almost always stalled, and has a small riding arena. They also charge extra for blanketing, giving supplements (even though you provide, etc). You provide everything but hay and bedding, and they do all the labor minus exercise your horse for you (they do, but for an added fee).
Anyway, this is one of my best friends. She's the one who I currently am leasing a barn with where we keep our horses. We split everything 50/50 and have a really good working dynamic as well as friendship. I know her horse as well as I know mine. I trust her. The place we're at is 100% self care down to that we even have to maintain the pastures. We provide everything as well, including hay, feed, and bedding. We used to pay $100 a month, but that felt high for what it was, especially since our stalls were way too small (8x9...). I talked to our friend who's barn we are leasing (we take care of his horse too), and got it down to $50 each. We go twice a day, depending on the day (we alternate), but both of us muck our own stalls and take care of our own horses unless one needs the other to take over if one has to go out of town, etc. Self care has been a nightmare because it's so much traveling, and what gave me the motivation to finally get my own farm set up sooner than later.
With that said, hopefully that's enough backstory to get an idea of the area and what our current situation is. I just built a new house, and currently waiting my turn for the barn builders to come put up my barn. She needs to know what I'm going to charge her to plan for her budget so I need to come up with a fair figure. Also please keep in mind she's my wheels -- I don't own a trailer, she takes me everywhere I need to go with my horse (I don't ask her to take me to lessons even though she has offered, I didn't want to drive her nuts). So relationship has a lot of give and take on both parties, I really want to stress I want to remain fair and don't want her to feel like I'm overcharging. Our friendship is also very important to me, so I never want money to become an issue. So far it hasn't, and we've done really well for over a year working together on the barn lease at current place.
To make this easy, she's going to provide everything for her own horse. What I am providing is a stall, full use of barn, pasture/turn out, feeding, mucking, watering, haying, trailer parking, sheeting, blanketing, fly spraying, etc. and anything else a regular boarding barn provides. So basically labor and the cost of water (which is expensive in my area). I really, really don't want to over charge her, but I also want to make some money back from what it'd cost to keep a second horse. She said she'd come 3-4 times a week depending on her availability to come clean her own horse's stall to give me a break. Since our horses are moving together, I won't know how much only one horse will cost to keep, and then double, so I'd have to come up with a figure to start with.
What would be a general price to start at going into this? Hope that makes sense and thanks in advance!
