Too expensive? Compare the cost of a lease fee to feeding your retired horse.
Not sure OP is coming back. I think she was expecting to get the address for the magical farm that takes care of everyone’s broken horses gratis so they can buy a new one 
I think she’s a bit green/inexperienced in how these things work and was not expecting the answers she got here. It’s tough to figure out what to do with a used up horse, I think it’s admirable that they’re not dumping the one she has but she’s probably a bit unrealistic to expect her parents can/should/will buy her a new one for the two years she has left between now and college.
