I recently ((Oct 2015) started investing in RE and formed an LLC.

If you buy with llc , you already in rent control it doesnt matter what number of units you own, But current rents on those buildings are actually ok for DC, Issues are the buildings where rents are in $500-$600 range..

(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?
