As a typical millennials I still live at home with my parents with some student debt, about $34k remaining.

Minnesota metro real estate investors, and millennial investor focus group are all great facebook pages/ meet-ups that are nothing but education 

I also have a slightly jaded view on millennials not being able to afford housing because I talk with many people in my job and I can't count the times I hear about how people can't afford to buy a house when in subsequent conversations I find out they collect premium shoes and have a whole closet dedicated to them, go out to eat/the bar 3-5 times per week, and have high end phones, TV's etc.

With Millennials having trouble buying homes because of student debt and Baby Boomers unprepared financially for retirement, how is that going to effect the real estate investing market?

Not traditional, but pretty close.Before the word "hack" became trendy and overused by millennials to describe everything from lowering the cost of housing to making your own kombucha at home, basically we just called this 'frugal living' or 'having a roommate'. 

I am unfamiliar with the rules and regulations or rent rates in your area, but I can give some basic advice on owning and running communal living homes. 1) Coliving in the residential or small multifam market tends to break up into three groups: digital nomads (who pay more, but want all the amenities), traveling nurses, doctors, students etc. who will stay for 1 to 6 months (this group had been well known in real estate investing for a while), and people looking for affordable housing (often millennials and retirees).

I have all of the things needed to qualify for hard money but I haven’t purchased a primary residence because I’m in grad school & don’t meet the DTI requirements yet (like most millennials 🤷🏾‍♀️).Will flipping through an LLC prevent me from being a first time home buyer when I’m ready to purchase a primary residence??

Just a warning to the millennials and others who don't realize that there's nothing wrong with a job if you like it.  

I don't know how the large MF dev projects in progress/recently permitted will affect this.Do the demographics/psycho-graphics of new residents (Portland is still projected to have large pop growth/influx over next decade) conform to "Millennial Mindset" (not to pigeon-hole Millennials) about what ideal living is?

(ie. young families, young professionals, pet owners, millennials...ect.)
