Do you work with specific mortgage lender whenever you can? Maybe you're an agent specializing in houses that need flipped and your contractor is the bees knees.
Co-Marketing can be the relationship you are looking for. It's a great way for both of you to advertise and split the cost.
As an agent, your primary goal in advertising is to connect with real estate consumers and differentiate yourself from other agents in your market. By having lenders pay a percentage of your advertising, you can secure additional views in your local market and deliver a more comprehensive service to buyers by linking them up with a financing partner.
