Wouldn't recommend boarding, it would cost you a fortune. Here board fees include regular feed, water and salt, anything else is coming from your pocket.
If you kept it at home then that's another ball game.
Try leasing first if you can ( part lease )
Paying $350.00 a month is alot of money for anyone young or old. Plus you will have to pay gas, maybe insurance on your vehicle, oil changes ect.
You could probly by your own land for that much a month and own it in the end.
( meaning no offence to people who do board or have boarders.)
Just giving my thoughts.
