My goal is to achieve financial freedom by age 36 and to understand various aspects such as investing education, strategies, business planning, properties, marketing, and exit strategies.

On a side note, oddly, the tenant before her was also a single woman, around the same age, stayed in the apartment for 10 months, no communication or heads up, left around the same time of the year.

I've been at this a while and have over 70% equity in my combined portfolio, and I'm over 50 years of age, so I don't look at creative financing options. 

I could spew more details, but it would help to know more about your age.

All rents you get from this property has to go back into the SDIRA but if you get a 20 year mortgage (that the rent can cover) and can pay the rental off by age 65 you will have turned that $90K into several hundred thousand’s of paid off real estate.

You are at an age that you should focus on cash flow rather than appreciation.

There are still deals to be had, aging population, probate deals, etc. 

What I am looking for at my age, is properties that will flow in the future to fund retirement travel, and MTR is where I am headed.But the reason for this post is I now need a structure(s) for what had been a concept. 

I would say the condition and age of the property would have a lot of sway in your decision for whether or not it's worth it.

I think we will see more "adult" families living together...kids move back in or parents move in with kids.The traditional apartment model was based on 12month leases, but jobs are not always 12 months and people want flexible terms, so co-living often offers that.Seems like younger people between 20-30 and some other age groups don't want to get married and start that housing pathway our parents and grandparents took.
