Lease and then possibly buy her
I think you should lease so you can get to know her better and really decide if you want to buy her
I hope that made any sense.
My coach told me that I should full lease my horse that I am currently only quarter leasing for 6 month to give me an idea if I would have the time to take care of him or if I would loose interest in him. It would give me six months to decide if I would want him. It is an idea but I would definitely lease first before buying especially if it is your first horse.
