Find one who hustles for his/her clients.

It's extremely unlikely another agent would have any idea what you're offering and trying to explain that to their client and negotiate on their behalf would be a nightmare.

My potential client has shown me proof of funds.

As a landlord, with positive cash flow it is difficult to agree to sell the property.  

My definition of a tough market is one that is difficult to obtain a decent ROI.

@Elizabeth Ricci - short sales are a little more difficult but also due to the timing you also typically have more outs.

But, they are difficult to sell because many condos come with a space and rental spaces are ubiquitous. so just somebody wanting to buy a space isn't on every street corner. 

Being a commissioned sales person myself, I understand there is a certain amount of time that you must invest in someone to build the relationship before you can really claim them as a client and claim ownership of that person amongst my peers at my store.

Originally posted by @John Thedford: it sounds like you have put the horse before the cart and my question is why would you sign a contract on something if you cannot purchase it that doesn't make sense Well I've read that if you find a good deal where the numbers make sense then finding a buyer shouldn't be difficult if you truly have a deal.

Or would that be difficult?
