I'm looking for visual reference material that would provide an at-a-glance display of at least the essential puzzle pieces to a real estate transaction specifically concerning the entities/parties involved & their role.

If you have a forced air system, rooms (be they closets or a small room - but generally speaking an area with a door) and there is no supply in it, they can get quite cool - even if the bedroom is comfortable.Before poking holes in walls (which is all you really need to do, just drill a 3/4" hole and inspect... visually or by sticking your finger in it... very easy to fill/patch), I'd check to be sure that the area above and below were insulated if they are attic/crawlspace/unheated basement.If it's not insulated, you could remove the drywall and install insulation or you could use loose fill using a series of larger holes - just be aware that horizontal bridging will require two sets of holes for each stud cavity.As for installing cedar... depends on type and thickness, but I prefer having a substrate regardless.

That way I can really learn and understand the root of what they mean, and it is visually nice to see as I learn.My only critique is not easily knowing what cells to input, versus what ones calculate.

Visualization and Affirmation are easily done on my walk. 

The problem was that framing take offs were still manual and it wasn't at all visual to the plans.

Below is a very good visual on how the real estate cycle works.

I'm somewhat of a visual learner.

To protect your investment, I recommend installing a security cage that provides a physical and visual deterrent.

Now, I understand why they adopt "no pet" policies and have already been stunned at the horror stories (and visuals) I've seen.

I realize that things that should have been noticed through visual inspection should have been assessed prior to determining my offer amount.
