They have all graduated & are now interning in medicine & radiology.

Hello, I am brand new to REI, I am currently renting an apartment with my brother, in college, and graduate next May.

Anecdotally for reference, a friend who graduated from the Citadel in 2020 paid $1k/month for a room in a house just off campus in Hampton Park Terrace (utilities included) around that time.

My insurance company doesn’t allow undergraduate or graduate students.

I would recommend all HS graduates join the military. 

But difference is newly licensed appraisers have an entry level licensing that kind of has built-in "training wheels", limiting scope of what they can appraise, and with a graduation of appraisal licensing requiring experience credentials and additional education tier's be meet. 

Since you are just graduating college you may already realize that it's not what you know, but who you know (as a personal note, I had college friends that were barely passing their classes however they ended up with really good paying jobs due to "who they knew").

If you take in Seniors, then they will graduate within a year and turnover will be high.If you rent by the room (just like a quad in on-campus housing), then you will generate more revenue than if you treat it like a SFR. 

I graduated with my degree in Marketing but was always interested in real estate. 

Upon graduating college recently, one lesson I've learned is that the best professor we can have is ourselves.
