On my lease I charge extra for visitors, back then around $50 to $100/month each. 

Any suggestions of what sites to visit or what videos to watch to research the in depth details of all types of lending, %s, etc?

If yes, do they make a trip to visit? Or

It helps keep visitors on your site longer, and keeps that bounce rate down - this is another factor.

The meetings are free for 1st time visitors and after that we have a door cost at $10 a month to pay for the room we use and the speakers meals.

So my 6 unit has a problem with visitors from across the street parking in my private driveways for their illegal “business” purchases.  

Bottom line was that visitor count stayed steady at around 9.5-10 million people.

I have just sent my first "You'll be here soon" email to the first visitor, who will be arriving in two days.We are doing all of our final safety checks, such as adding carbon monoxide detectors to the existing smoke detectors, putting in the child protective outlet covers around the property. 

We have a division-1 football & basketball teams that regularly attract outside visitors, as well as having Interstate-80 run right through our town.

You might not like the house rules but there is no "injustice" in a landlord saying no overnight visitors and no pet visits - if those are her terms, you can accept them or find another property to rent.
