Funny the appraiser community refuses to point that out the the lenders, which are truly the entity (FNMA, not appraisers) that determine how a mortgage appraisal is calculated - but I digress on that one.But getting back to you, let me point out the flaw in your analysis.

Again, this was only the fact because taxes were the big flaw in the property.

I clearly thought wrong and discovered it was a mandatory cost expense if the tree is violating code.

I also just discovered that Udemy has a lot of information/courses.I realize that the information I need could likely be found here on BP, but I think I learn better with a step-by-step method.

The lenders likely won't even discover the issue, but there is a definite risk of having the loans called.

They will be conveyed to you at closing...amazing how many BP investors discover there were none collected.  

The electrician's bill for this one was less than $200, so we got off easy.While driving around checking for storm damage at all of our other houses, we discovered that the tenants at house #6 had acquired chickens.

Had these bricks been structural in nature, like your situation, that bowing may have been a fatal flaw and caused us to have to knock the house down. 

As you've discovered each one has it's own pricing.

I recently discovered Kris on YouTube and he motivated me to really push this rental property investing.
