I agree, best to stay away from the OTC,.. no liquidity on the OTC and that can hurt if you need to sell. I am a canadian so I don't have any solid recommendations for a platform to trade on in USA, although I would suggest checking with TD Bank. They are a Canadian bank and I am fairly confident you would be able to execute trades directly on the canadian exchanges with an account through TD.
Might be good to watch how it trades for a bit before jumping in. It has been appearing that some houses are accumulating lots of shares, Jordan in particular, but so hard to tell with 001 sells.
Good luck with the house hunting / purchase, cheers.
