New Colorado investor with several questions

[Thatcher Glode]

Hello BP,

My partner and I are planning on buying and holding multifamily properties in Colorado. We are trying to figure out where to buy in Colorado. We are planning to buy multi-family units and are trying to find things as close to neutral or positive cash flow as possible (we are aware it can be difficult to find cash flow positive deals in CO at the moment with high property values and rents that don't equate)- So... our plan is buy properties that may need a little work, put in the work, bring rents up as much as possible, find quality tenants, and repeat. Questions:

What I don't understand is whether I even need a real estate license to write offers or if that is only required for selling properties? 

If I don't have a license how do I learn the process and paper work for writing offers? 

If I were to gain a license would that allow me to sell properties on my own or do I need to work for a brokerage? I realize this is a ton of questions and I am brand new. 

Say I found the right duplex for us to start after running the numbers on BP tools based on Zillow estimates, I saw the property and thought it was a good fit, the loan was approved, if I don't have a license how do I find the paperwork and legal forms needed to write an offer? Do people reading this think I should do a program and get a RE license regardless?

Thanks for any assistance.
