I recommend getting the PRO so you can have access to other features.

We once had a tenant demand a new oven when he had accidentally engaged the timed cooking feature and he couldn't understand why the oven was not heating up. 

Only easily found, easily matched, easily replaced baseboards, moldings, and other features that might get damaged.4.

This building was built in 1991, it's two stories and also features window AC units. 

You might consider installing water saving features (replace old toilets, install water saving shower heads, etc.) and actually asking the tenants to please try to conserve water (if you have a good relationship with them). 

I don't use the other features they offer (application, maintenance requests, document sharing, listing syndication).

But to me, the up side and my favorite feature is that the tenant can report payments to help build their credit history.
