I have been examining deals for weeks to try and get the feel for how to be successful in REI.

Cost segregation studies examine all of the various parts in the property, including the doors, roofs, floors — in fact, just about everything.

You just can't start a brokerage on a shoe string as I did in the old days.....but I admit, it was easier for a bank examiner to open shop than someone off the street

Examination of the actual loan documents would reveal the actual security terms.  

@Munya Ben I haven't really looked in that area or examined the site.  

If not, what I do is find the properties that fit most closely then examine the differences and do some simple math to add and subtract value.  

Oh, this is what examiners live for!

Its worth examining all coverage on a cost/return basis.

I believe you can take examinations outside of OK, and you'll have to call PSI (https://www.ok.gov/OREC/Information_for_Obtaining_a_License/index.html#arrangements phone number is here, won't let me post on BP) for testing locations.  

So at the end of the day it is indeed trust in the sponsor and a close examination of past performance.
