Tbh I would be more concerned at 25 that OP can't afford to live independently of her parents and is considering upping the current costs of her horse, rather than considering setting aside a reasonable amount each month to enable her to buy or rent a place of her own. Surely the benefit of living with your parents at that age is to enable you to save a decent amount of money to set you up for getting on the property ladder?
glad someone said it. I was out of home at 16, car at 19, mortgage at 25, dog at 26, horse at 34 (would have been earlier except I went to uni at 28). There's no way I would have had a horse before the mortgage (and I was single) and no way I'd have lived with my parents in my 20s. And it was pre minimum wage and Cambridge rents.
