I think it depends on the individual and opportunity.

The reality is the opposite - if it's not in writing then the PMC doesn't have to provide the service or can charge extra for it!

Perhaps some time will provide clarity in one direction or the other. 

Yes, generally speaking, depending on tenant class, it's best not to get too friendly with your tenants.

I find that depending on the market $300-500/mo are fairly normal and if compared to what you would pay with a single family home on some utilities, maintenance, and management, it's a good deal.

Or paying off my debt, while I provide them with a nice house to live in instead of an apartment. 

Also, you will have additional occupancy tax depending whether you are in the city limits or not.

As long as you're living in it as your primary residence and can provide proof of that, you can continue with Owner Occ tax rate.

When it comes to furniture/design it depends.

I'm struggling to understand some aspects of your response, but it provides some things to think about.
