Not as precise cuts, or putting in 8 support brackets instead of 10 on a single run; knowing that "meehhh... they'll never see it anyway, and they wanted a cheap job sooo..." 

This is not a precise number, because market price is always changing based on recent sales and demand.

The front of the card has precisely what I wrote on my last post.  

Make sure of the precise wording - - separate accounting is not the same as separate accounts.

We do not know precisely what amount of time would create a forfeit of the Mortgagee's right to raise the claim either.  

@Mahdi Mike zip code alone would not be a very precise way of estimating vacancy--because there can be highly desirable neighborhoods (low vacancy) and completely undesirable neighborhoods (high vacancy) within the same zip code.

REI is a long game with precision, meaning you need to know the market long term and be precise on valuation.

You referenced low vacancy but being able to plug in hard numbers to a calculator would be a tremendous (and precise) boon when using the BP calculator.  

The rules about what constitutes an "egress window" are quite precise, so unless it's got a door in the bedroom I'd check up on what the local code requires rather than go by if it seems big enough to climb out of.
