I know SC is steep for non-primary residents.  

Ive apply on two different accounts and sent customer service emails and no response. 

Since the DADU is on the same property as my primary residence, can I place the DADU in an LLC, separate from my primary residence, to protect my personal assets from liability?

Does anyone know if you can use a DSCR loan to build a DADU on you SFH primary residence property?

That was 20+yrs ago... still miss it but, don't miss the headaches (which I didn't mind at the time of course) lolIt's going to be different with it being as a Rental or Investment for you (instead of your own home). 

I have a handful of properties that I have tried to list in different states.

There is a difference between your acting as a HML and a partner, if you and he join together in an LLC you can act as the money partner making the loan internally in the company without being subject to lending regulations as an outside lender.

I was planning to use my 0 down VA loan on a new primary residence.

your getting the MLM  enthusiasm you deserve it pitch. reality is far different as stated above.

In the end this cost segregation approach is only a Timing difference - you pay less tax now, you pay more tax later.3) Consider if an S-Corporation makes sense.
