Just reduce there rent by $5 and they will be happy to do it.

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.

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

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.  

Normally when a  property is advertised as "cash only" the property is in poor condition and/or the seller wants to reduce contingencies and opts for a cleaner transaction.

Remember that the leveraged purchases are not going to add significant cash flow immediately and borrowing against existing properties will also reduce their cash flow.

This greatly reduces weeding.  

As for your neighbors, they could have exemptions like Homestead, widow, military disability and many others that can reduce the amount of taxes.

Like anything it has to stay balanced but small gestures go a long way in reducing turnover and mitigating many "would be" issues. 

House hacking with an SFDU could be a smart first step since it allows you to reduce your housing costs while building equity.
