Maybe you should talk to the tenants and try to find a compromise.

No one is moving, landlords aren't trying to rent, things are very much status quo for a large portion of what likely compromises the "norm" in the thick of quarantine (May).2.

I suspect you really are stuck with an angry landlady whom you're screwing out of this month's rent -- that part of your narrative seems too specific and detailed to be wholly the product of an otherwise sharply compromised imagination. 

@Trever Good - now this is a great compromise that i feel would likely make everyone happy.

You are right to not want to compromise on quality IMO, though.

I do the same but with the low-interest rates, it is possible to get more without any compromise on the quality of asset or management fees. how cool is that?

So if you are aiming at students,  I would look very closely at things like getting as many parents and guardians as cosigners as possible,   and require people to actually do have verifiable income and relatively stable employment  (not necessarily same job a long time,  but a succession of same kind of work,  ideally with increasing resposniblity)  Even at minimum wage full time I'm guessing it should be possible to afford a rented room in a 6-8 bedroom house no problem,  so don't compromise on that.7)   Parking:   if you have onsite parking,   you probably won't have 8 spaces,  so reserve and charge for it.   

I suggest you find a compromise in-between that you are comfortable with.

That way you can setup the financing to work for the current purchase and not compromise the purchases you're planning in the future.

The NDA you suggested is also a compromise.
