Lower the cost to like 400 and I think we are in a better ballpark.

Make them like they are in Red Dead Redemption. Expensive to buy, but if they die there is a timer before you can have it again, death is not permanent. Also, when I press a button I whistle and he will come to me as long as I am outside.
Sure 1000 gold will be pennies later on, but at the beginning, when a horse is actually useful and you can't fast travel everywhere, 1000 gold is a good chunk of change.
