Perhaps not intentional understood.Good luck with your search! 

I just purchased a primary residence with the intention to rehab it & live in it for a few years before reselling.

Don't intentionally burn any bridges because bankers move around and you will see the same faces elsewhere.  

I know there are many local mentors who have a pure approaching and good intentions to help folks out.

I'm sure that if you had any intention of your post in any way being serious about mathematics behind real estate investing, you wouldn't have bothered putting together something that's so clearly made up/opaque.If you're running a model, by all means, share the details about inputs to the model.

If you have no intention of pulling money out for personal use, an equity line pulled out after closing on the replacement property is of no benefit to you By way of a disclaimer, my recommendation is limited in that I have only been provided the facts above and should other facts be provided, the advice/recommendation would likely change.  

I am not holding my breath on that though.

Basically, I either don't understand the questions and/or I don't understand the intent behind it of why you ask.

Vaulted roofs can get hot you need to be careful check out the right way to do or you can end up with buckled roof from too much heat .A roof needs to breath, it is hard with a vaulted ceiling be care full typical vents will not work tricky do your home work !!

Reason ... because if it was intentional, the sender would be taking a big risk, because the first thing I would think to myself is, " If this person missed this, he/she is probably not detail-oriented enough for me to want to work with".
