You can work out better splits with brokers vs wholesalers. You are more prone to getting quotes faster from the broker, sometimes wholesalers will put your app at the bottom if you are new.
Also if you push paper through a broker a lot of the times they will help facilitate the process. They might be willing to pay half for leads, give you x-dates to call. They will be more concerned about you succeeding vs a wholesaler working with hundreds of brokers.
