Showing ID is not only a safety measure for yourself and the other person, it also helps to reduce fraud if someone is unwilling to provide identification and is being this difficult with a simple ask, then I would also question whether or not they would be a good fit as a tenant

 $9k/$72500=12.4% Rate of return (not including any closing costs which would reduce this return).  

Unit 4 - short-term rental (this would be best for a unit with a separate entrance so you reduce the bother to other tenants because the changeovers will be more here)Is anyone doing all three (LTR, MTR, STR) in their multi or house hack now?

My strategy (at the time) was to aggressively pay down my mortgage, and the recast allowed me to reduce the monthly committed amount.

I'd also suggest considering a partnership if you feel comfortable with that in order to reduce the risk completely on you. 

Many other projects have reduced or suspended planned CF distributions and I've also had a few capital calls in which I did participate since the business case still made sense (the MF in Florida had a capital call to finish construction and get through stabilization and it still returned the 32% IRR).I expect almost all of the deals to be OK, just later exits than originally projected.I am very concerned about one project and have already written it off in my head.  

This reduces their upfront cost so they don’t need a large deposit.

That said it is possible that you need to evaluate your stays and decide if it is worth taking shorter stays or sticking to some longer stays to reduce your time commitment and maximize the revenue for time invested.

If your leasing application process is thorough and well thought out, and if your lease agreement has been well drafted by your local attorney and if it includes clauses that permit you/your property manager enough latitude to maneuver and anticipate undesirable tenant behaviors, both actions and inactions, and you have operational processes which align with enforcement of your lease, then you've done all you can do to reduce this inherent risk of an undesirable tenant.
