I heard about this concept in theory and i don't know if this situation would be included (firing a poor buyer) but would appreciate the insight :)

A new rule in 2014 from the CFPB will deal with the concept of "Ability To Repay".

Concept of the money/resources work for you and not you working for it, difference between rich & wealthy, difference between assets and liabilities.

Now that we touched on some of that, I am curious what the numbers mean in your post and if the was a misguided conception to the price of these types of assets.

The app allowed you to practice the basics both visually and aurally to solidify concepts that are fundamental to understanding higher level theory. 

I don't like this concept as I found that in general; if the tenant thinks they will have to pay anything - they always put off calling for the repair.

Roy,I love the innovative idea.Your Concept: negotiating a convenience for your niche population and bill users later.Possible Improvements: negotiate an affiliate relationship with service provider (a little kick back).Potential Other Uses: similar arrangements with coffee shops, laundry mat, groceries stores, etc.No since in just focusing on rents when you could be an agent to help with all living and lifestyle expenses.

This concept in total, applies to loans across all performance and is not unique to performing loans.

The concept of getting carpet cleaning services through a GC seems odd to me.

It's a good concept but it is still lacking.
