I would set up that other bank account in QB. If you are tracking only the Real Estate Commissions, use it for the deposit account when you receive your commission. Then you can use it when you draw from it as well. If you use this account for a lot of transactions associated with your real estate business, I suggest you record all the transaction in QB. If it is a personal account, set up an expense account called Personal or Non Business and record all the non-business transactions there. A better choice would be to have the Commission checks deposited into your Real Estate business account.
