@Elyse Natalino You will have to explain to me what the BP 4 Square Method is.

I like the assignment route and my sellers never asked one question when I showed up with the contract naming my LLC and/or assigns as buyer, a couple of weeks before the close I met with them and explained how the assignment worked that the numbers did not change and they never questioned it, closed on time with out a hitch.

And can clearly explain the pros and cons of using each sort of metric for analyzing a property?

true, but your asking for objective data to answer a subjective question.  

Too complex to explain here.

Can anyone explains why the City keep approving luxury apartment new construction one after another instead of building an affordable apartment for the low income group on the same piece of land?

I explained to the bank I signed this meaningless document for their convenience, so underwriter can get a bonus for higher numbers of closings.

I explained her monthly costs associated with all expenses were likely creating negative cash flow and I was offering her a way to make money each month without having to be a landlord.  

Has your agent not explained your contingency periods?

It's hard to explain, but it's a mish-mosh and hodge-podge of construction to some extent.
