Any input on the appliances noted above would be appreciated.

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.  

We are not a marketing company that sells other operators' properties. 

Very few people operate their LLC correctly and therfore this just gives them a flase sense of security.Moving into a LLC can also trigger the due on sale clause.

He calles them "poor people" "economically disadvantaged" He threatened to evict them if they don't rent his appliances like used ceiling fans.

I recently toured a property in Phoenix where solar power and water-saving features cut operational costs by nearly 20%.6.

Those are not the most important parts of the operating agreement.

But my question is that if we consider other operating costs like maintenance, capital expenditure, vacancy, etc then this property won't cash flow, so is this a good deal?

We still need to calculate appliances, flooring, windows, HVAC, fixtures....My point is that we need to be putting away money to keep our properties in max market rent rate condition.

Everyone else is through tech, private equity, stocks, building operating companies, etc.At the end of the day, investing is investing.
