Working w/ wholesaler and real estate agent?

[Andrew Merritt]

Is it OK/ethical to work with both a wholesaler and a real estate agent at the same time?  I've been working with a real estate agent for a little while trying to find my first deal and I recently got in touch with a wholesaler.  The wholesaler has asked me to sign a NCND (which I'm OK with), but it just made me pause and wonder if it's ethical or I'm stepping on anybody's toes.  I asked my real estate agent if she's OK with it and she doesn't even know what a wholesaler is.
