It’s not worth my while if it’s less than $100/day… but I also am the type to do the extras: clean the hay off of the stairs, drop extra hay for you so you don’t have to when you come back, tidy up the barn, etc…
A lot of people here do want to pay less than that a day, but it just isn’t worth it: factor in the time it takes to get there, the gas, the time it takes to do the work, any extra duties you have to do, etc.
For instance, I house+horsesit for a family friend - includes AM feeding, turnout, and stalls – and those stalls take me (someone who is fast at stalls) at least 20m each because the owner wants absolute free-choice hay in the stalls at all times (but doesn’t want hay nets). I completely understand why she wants that and I follow what she wants but it adds tremendous time to your chores… So it takes me about 1.5hrs to do the stalls alone, then you have to dump/scrub/fill, set up feed for tomorrow, put hay in all the stalls, and then before I know it, it’s been 5 hours… then I have to come back at 5PM to bring in, dump grain, top off any waters, and then I do night-check at 10pm which includes topping off hay, water, and picking the stalls… so it’s about ~7hrs of work not including the gas and the time it takes to get there… and $100 starts to look much more reasonable. Family-friend pays me about $250 for the weekend (Fri-Sunday) – a little less than what I normally want, but she is a family friend. It is HARD work and IMHO, for anyone else I’d expect much more.
I also learned the hard way to not agree to anything until you go over the routine with the owner. You also need to eyeball for yourself the logistics and layout of the farm: some things make chores so frustrating, and others so easy – and that should factor into your base charge for services. There are some things I just do not want to do; things like cleaning out chicken coops, removing days worth of manure/hay from a stall, etc – and no amount of money makes me want to do it… I’ve been unpleasantly surprised a few times to see a note saying “oh also, can you do this…”
I also only housesit now for people who are friends of family or people who come “vetted”… People are CRAZY and can expect the most unreasonable things… and even having them be friends of family is no guarantee they’ll be reasonable… For instance, once my sister agreed to dogsit for a friend of the family who wanted her to stay at the house Christmas weekend - sister only agreed if she could have her long-time BF stay with her, as you know, it’s a holiday and you should spend it with loved ones… friend-of-family said “sure, that’s fine”… The day she left texted sister and said “you know I’ve been thinking, I’m not comfortable with that so no he can’t stay at my house…” Something like that would have been perfectly reasonable and fair if it was laid out before my a housesitter took the job, but it was not, and my sister spent Christmas Eve alone for something like $20 a day…
If it something light work, no stalls, and extremely local, something like $40 per visit is fair. If it is something with stalls or stacking hay or regular barn chores, 100/day is much more fair.
