In most markets and neighborhoods you can establish a pattern but in markets like these it becomes completely subjective by using the extraction method.

Each property has it's own LLC and bank account for which rents are deposited and expenses paid, but if one does not extract money from these business accounts, how can you keep increasing personal debt without increasing personal income?

As an amenity, it’s a selling point for managers who know the Denver market.The previous owners of the Fletcher Southland's were investors focused on extracting cashflow from the property instead of re-investing the necessary capital back into the property to force property appreciation.

The note on it is 438K and I want to do enough work to extract 88k worth of value out of it.

Depending on your current overall tax situation, you might want to extract some of the equity (to gain some tax advantages) and redeploy it somewhere better (if you can do that) - then you should look into an asset based LOC or cash out refinance loan.  

All the equipment and knowledge are there to do those extraction and quality control.

like @John Umphress stated, you may be able to extract a list of charities that help paying the rent. 

What should I be asking to extract all of the pertinent information that will determine if it is actually a deal?

That means anything on the mls is overpriced, and "wholesalers" that do manage to extract some "value" out of the marketplace aint gonna give it to you, cause they don't have to.

This might be an overwhelming factor.We have lots of meaning to extract from available data and we can describe meaning with terms we know, such as the following:- Open Calendar Daily Rate: daily rate of open (available) calendar days.- Closed Calendar Daily Rate: daily rate of closed (unavailable) calendar days.- Changed Closed Calendar Daily Rate: daily rate of calendar days which have been observed to change from open to closed, over time.Are there existing terms which already describe what I've mentioned?
