I would not recommend it from a functional kitchen perspective.  

You don’t see this in syndication books because it’s not typically a syndication sponsor’s function.  

It tracks well with what I have heard from some Airbnb specific managers in my area and was so easy to use (the free functionality, I haven't messed around with the paid stuff).

I have several SFR's that I manage using Cozy....I am happy with the functionality for my needs to this point.

The BEST way to protect yourself is to know the law, obey the law, ensure the property is safe and functional, and treat people honestly and fairly.2.

I'm looking to brush up on these basics as I continue to purchase more rehab properties so I can have a general concept of what I can and can't do when visualizing a rehab.

However, you very well could be sued for refusing to rent an upstairs unit to someone because YOU didn't believe they had the necessary mobility/functionality to live in an upstairs unit. 

In California, for example, a Realtor typically fills out the Agent Visual Inspection Disclosure (AVID) form which is designed so the agent can disclose the "material facts affecting the value or desirability" of the subject property.

I would take the time to clarify expectations in writing and also to make an agreement for what you all believe should happen if for any reason he is unwilling or unable to fulfill this function in the future. 

Appreciation is largely a function of time.
