I agree, contact a broker for sponsorship in your area and see if they can help.

My only concern is that perhaps a few weeks will go by until I get sponsorship and that's time I could've used to market the property and save money on taxes. 

Do I need broker sponsorship if I am not planning to buy or sell retail?

I am interested in learning about syndicating and sponsorship for bigger deals and properties.

I do more signs, team sponsorship etc.

You might move to another state, as you won't have the luxury of job choice if you're planning on work sponsorship.

(I have the Series 7 and Series 63 securities licenses so I understand sponsorship).My question is how to I approach a broker to get licensed?

In commercial loans, they look for the sponsorship team to have a net worth equal to the loan amount.

There are sponsorship teams who are syndicating debt structures for their properties now.

I can tell you this, if everything is perfect - all syndicate partners have great credit, you have plenty of reserves, relevant experience, a solid business plan and financials, and Feasibility and Environmental Studies completed in the area you are looking to purchase or develop, all with at least 1 US citizen sponsorship... you may be able to get close to 4%... maybe.
