The idea is we scout neighborhoods looking for distressed housing, generate a list of leads, and then sell an exclusive list of leads to an end buyer (wholesaler/Investor). 

@Aaron McGinnis is correct, "No job but mine" clause will not hold up in court, although you do not tell them what to do, but you are controlling their action by not allowing them to work for anyone else which makes them exclusive, that alone falls off under the behavioral common law under independent contractors.

We are a HUD Brokerage that works almost exclusively with investors in Central & Southern Florida.I can e-mail you info.

@Clarissa NesbittIf there is listing agreement with the seller, get an addendum that seller can sell with agent or she can find a buyer herself.See "Exclusive Agency Listing"An exclusive agency listing is similar to an open listing except the major difference is the broker will represent the owner.

Being a GC, your subs have inclusions and exclusions, you have to cover all those exclusions, say for example the sub excludes trash removal or dumpster fees and only includes demolition and trash haul 30 feet from the driveway, meaning if you cant get a dumpster in there, you as the GC is responsible of paying all dumpster fees and all expenses of the hauling the extra few feet from that.

If you have an exclusive agreement with your current agent, then the NAR Code of Ethics prevents another agent from doing business with you.  

If you purchase a dp3 and the property is unoccupied you will have a theft exclusion.

When I do get an exclusive duplex available, my buyers are sharks and take them immediately.

I know successful investors that deal exclusively in the roughest neighborhoods, and others that won't go near them.So it really comes down to "Who do you want to deal with?"   

For over 10 years I've been doing Sales almost exclusively.
