There is not a lot of protection for landlords and Rent Control laws are formed and function with the assumption that anyone that owns investment property is "rich." 

At the OTHER end, when renting to STR /MTR guests, there may be devices that either provide security, safety, functionality to your furnished rental that you don't want guests accidentally or intentionally disabling or damaging or using,  ie IoT devices, cameras, etc.   

I’m in a group home with highly functional clients who get some supports and are in transitional housing.

These items are of course public knowledge on the building codes and what the standard should be, but to follow that along with creating a structure/addition that will flow properly and functioning. 

I have excel experience and with time could create my own functioning model.

So it would be good to make sure everything is function or some weird law comes out where it favors the tenant outlandishly (I am not familiar with the rental laws of NY).My suggestion would be a blend of previous statements and our concerns.

As far as replacing it, whatever would take its place would have to be absolutely slick, and I'm really looking for something that combines the functionality of RingCentral with a CRM of some sort to streamline contacting leads, tenants, clients, etc, for the purpose of scheduling texts/calls, text campaigns and follow ups.

We use OwnerRez, it has an initial learning curve but a lot of functionality once you get setup.

You'd keep garage door functionality. 

It no longer functions.
