Same reason why advisor fees inside of an IRA are not tax deductible. 

You'll need a lawyer to generate the paperwork and filings and experienced enough to give you general advice on the process, help you establish appropriate compliance and back office procedures.

Many investors bring their contractor with them on initial viewing, but it’s usually an established relationship.

I would turn the question back to you  - without a Survey how would you establish the correct placement of the ADU? 

When establishing the holding company LLC, you obtained an EIN for it.

My mom has established new lease terms with a 5 year lease agreement with the Company in an effort to protect herself against the possible liability that would come from having to remove the blades, and required a huge insurance policy to protect her against this too. 

Established families vs. single folks.  

Can you tell us more about the professionals/attorneys/CPA you collaborate with to establish Agent Trust/ Umbrella Trust, and Individual Property Trusts in the Austin area?

(Disclaimer: I am NOT a financial advisor or a CPA, I only show you stats based on what is available to me as a Realtor.) 

Seems reasonable that someone else could easily use tech to re-establish the lines for us instead of conducting a whole other pricey survey.
