MTR strategy in Denver area

[Trace Adams]

Hi all! I am about to close on my first home which is west of LIttleton, CO (off Bowles & Wadsworth specifically for those familiar with the area). The house has 2 beds 2 bath upstairs where me and my girlfriend will live, and a walkout finished basement with 2 beds 1 bath downstairs. We plan to rent out the basement on a medium-term basis - we are going to install a full kitchen down there, put a lockable door between upstairs and downstairs, fence off a private section of the yard, and there is already laundry down there, so it will essentially be an up-down duplex with a separate walkout basement entrance. Only negative is HVAC isn't split so renters will be subject to the temp we have it set at upstairs. Curious everyone's thoughts on 1) whether I should rent this out as an entire unit or on a room-by-room basis, and 2) what seems like a fair starting rent to list it at? Thanks!
