I just looked at a pig $100,000/door for $550/door GPI.

The problem with in door storage in multi level buildings, is you generally have to build it all at once and it takes longer to get to break even. 

A basement unit cost would be an additional $150k , so potentially need $300k to make it two doors.

This includes the door code, address and directions, anything they need to know about the cabin they're staying in, how to contact me, reiterates check in times, and again links to the digital guidebook.3.

Heat and moisture gets trapped under the house and the heat wants to rise but the LVP creates a vaporlock, thus inhibiting the mold growth. 

Make sure the bedroom has legal egress in case of a fire, either a legal sized window to the outside or a door. 

that we’ve learned in our 24 years, managing almost 700 doors across the Metro Detroit area, including almost 100 S8 leases.

Similarly, if vacant, inspect the property to ensure utilities are off and the doors are locked.

I initially wanted to do a BRRR but since I'm not the from the area, real estate agents are telling me I should maybe start out with a turnkey to get my foot in the door?

I would sell the properties.4 rental properties over 3 years won't make you much money.Maybe 100 per door per month in cash flow and a matching amount in appreciation.That is $9,600 over a 3 year period assuming you have SFH's.You are improving your ability to make more money in a better position hopefully when you complete your master's degree.You will make that $9,600 working 2 weeks.The sale of the home will hopefully allow you and your wife be stress free for those 3 years helping you make a higher hourly rate.
