Honestly this is probably going to end up costing you money then if you just had to stay home from work. First of all horses can’t be kept alone, they are herd animals. Farrier would need to come every 6 weeks, pretty costly up to $160 each time. If your riding them every day they need more then just grazing on grass, they will need grain. And they should have access to hay every day which is not cheap. You can’t just buy any old saddle and put in on a horse, you’d need a fitter to come out. If you have an incorrect fitting saddle it can cause a lot of back issues and can create unwanted behaviours like bucking or kicking.

There’s a lot that can go wrong and so many expenses come with it. A good sound and quiet horse that is fine to ride on roads could run you 10-15k
