Is it to maximize revenue?

If you can produce good revenue for a couple years with a business you will be able to get good lines of credit which is what I have done, but it takes time.1) Once you get that CC debt paid off make sure you don't accrue anymore.

Is the "gross revenue" $708.10 or $541.26 for this booking?

It is very simple to set up bank accounts, assign virtual credit cards, and tag revenue and expenses so you can stay on top of it.

The main thinking is that your increased revenue more than makes up for the increased expenses.Do you typically rent by the room and put each student on an individual lease?

And many investors, both local and remote, are finding properties with decent revenue returns and/or cash flow.

Some are little more that assistants, some have the knowledge and expertise to drive revenue and create more value.

Most people do not understand how Zillow generates much of its revenue.  700+ agents on BP buying leads instead of ~$200/yr for a membership is a nice new revenue stream for BP. 

I tried that market a few years back and price to revenue lacked, massively and it still does.

The focus now is on problem solving and not revenue.
