I have an old work associate that introduced me to the concept years ago and I know a decent bit about the mechanics of it, but not a lot of the specifics.  

Keep a journal of every property keeping track of the square footage, determine the price per SF on each. 

Could anyone please tell me of any such links, books, blogs, academic journals or anything similar?

I have explored the concept somewhat.

Stella is an Associate Broker with Burke Real Estate Consultants in California, as well an Associate Broker with Smart Concepts Real Estate LLC, in Arizona!

(See Detroit, New Orleans, Tampa, Jacksonville, where they are using the same concept to bulldoze blighted properties, they then lien them and have the right to foreclose on that lien.  

It is not quite as simple as that but that is the concept. 

(Because, those two concepts are TOTALLY different)!

Note that his advice was actually on my primary residence but the same concepts apply (pay more principal while you can, throttle back when you cant)
