Best approach to DMV realtor license?

[Brad Wood]

BP community,

I live in DC, own a duplex, and am planning to add to my portfolio. I have a full time job, so I'm looking for guidance on online or evening courses for the DMV real estate brokerage exams. Admittedly, I'm not sure if I need to take different courses for each, or if I just need to write the exam for each.

while I'm at it, I'll also ask if there are brokerages that only charge a nominal fee to hang your proverbial "hat" with them. I will maintain my full time job and this will primarily be to support my own investing. Hoping to get 1-2 multifamilies in the DMV andove out of my duplex into another in the next 5-7 years so would like access to mls and to make more compelling offers by avoiding buyers comssions. I do have a friend that will take me on, but I first wanted to assess options.

Thanks in advance,

Brad.
