And if they're just a little tech-savvy, they can import your booking calendar to their smart phone and see your entire schedule at a glance.  

Or the ones who can't ever pay rent on time, yet have expensive smartphones, enjoy the deluxe cable TV package, and drive fancy late-model cars?

They can be easily self managed from anywhere in the world with just a smart phone.

Alternatively, look at Tellus free smartphone app/ PM software which basically incorporates Naborly screening along with tenant maintenance/ communications and free ACH bank payments.

You should not be essentially required to have internet/a smartphone to rent from somewhere, even though the vast majority of the population does.

If you have a smart phone listen to all of the podcasts as well.

If you've got a smartphone, or a friend with a smartphone, there's no excuse for not putting up a photo.I can pretty much guarantee you'll enjoy much better engagement and connection here once you open up and show us who you are!

And, I would add that QBO isn't meant to replace professional accounting software or even accountant.As Charles said, the greatest and maybe the only advantage, is it ability to be used anywhere, anytime i.e. library, smartphone, hotel computer etc.
