Is it legal to give gift cards as referral rewards instead of cash?

Well I will be doing a rent to own on any property that the bird dog brings me, and then selling on a rent to own, so I won't actually be buying the property myself at any time. Unlike installment contracts (wraps), I don't need a credit license to do rent to owns, and since I am not buying the properties, neither I, nor my bird dogs need a real estate agents license. All my bird dogs will do is let me know of someone who wants to sell their property – they don't do any research, or negotiations with the seller – I do that. I don't see what the problem is.

I am in Queensland, but I still don't see a problem. The negotiations I do with a seller revolves around the option fee, length of the lease, price of the property if I decide to buy (which I won't), how much the rent will be, etc. The negotiations do not involve me buying the property, just controlling it under a lease and an option to buy. I will then offer the property to someone else under a lease and an option to buy. If that person does want to buy, and there is only a 50% chance they will, they will exercise the option to buy directly from the seller, not from me.
