Trying to get an institution to reply and comment in a timely fashion is comical.

In my mind the only viable option is good ole fashioned long term rental. 

Real Estate is just a tough bizz on almost any form or fashion takes work and does require some sales and marketing skills..

I have never seen someone throwing every one of the fashionable strategies into a single short paragraph.

Renters insurance price will vary depending on the value of the renters' personal possessions (furniture, clothing, artwork, jewlry, etc... whatever the renter chooses to have the policy cover) in the rental  the liability amount will be added to that base. 

A few appropriate wall artifacts or artwork can add to looks and feel of the rooms. 

Adding some artwork to help give the place more character - $100-200 on Etsy or Society6 can get you some really unique prints that will help your apartments show well in listing pics and really set them apart from the competition.If you have the space outdoors, the quickest and easiest amenities to add are a fire pit and BBQ grill (or maybe a patio as well, if you're so inclined). 

I am thinking normal utilities being provided in a communal fashion similar to many pitch your tent campgrounds.

Get the lock that also has a hole for a physical key  and then have a good ole fashion lockbox with the key in it as a back up Example of yale with key Dont get one like this without a keyGOOD LUCK!

Let's be realistic, scaling in a house hack fashion doesn't happen in today's world like the pre-Covid era. 5 MFs in 5yrs with just $25k to work with is a false reality.
