I do it by how I feel about a deal with my 20 years experience in the NNN field.

This entails building personal/working relationships with people successful in the field.

However, just when I THOUGHT I DID, often something happened totally out of left field that wrecked havoc on my predictions and analysis.  

There will be a field/comment in the listing process where the Seller will include "concessions" in the list price....I don't know how this will look like exactly but my sources say that the Seller will be able to communicate any type of concessions through the listing. 

Then when you pay your mortgage every month to your mortgage servicer there is a field you can add extra every month for your escrow. that way the next year your escrow account will not have to double up to catch up. 

IE  D box septic tank leach field all gravity feed.. 

Alternatively, by getting a job and apprenticing for a real business in the field.  

Ever think on that, why isn't this giant commercial building with this huge open football field of a roof simply throwing up solar?

Plus, the product itself is 17 years old, which is eons in the software field, so it's nice to not be using a startup.Unfortunately I signed up for the free trial and then didn't take notes, and now that I am getting around to the review the features are mostly shut off for me since I canceled several months ago to avoid paying.

I have no experience in this field aside from the books and videos I've been watching (Drinking from a fire hose).
