Here are some thoughts I had.Potential Backlash - I agree with @Erik Estrada that charging fees might draw criticism from some community corners. 

Nothing better than four draws and never a lot of money up front "for materials".

Further, a member of the LLC can take a draw from the LLC without it having to be regarded as and follow the for,Ali toes of a salary or dividend, so again can’t be used by a plaintiff’s attorney to pierce the veil. 

If you had eyes on the property and have a good idea on all this you can hit the HML for all the costs and take draws after the initial acquisition to do the rehab for the rest of the amount.

“No, I’ll release the money on draws, that won’t happen…” Ok, so you need margin for when it’s 50% done and they say they can’t afford to get to the next draw point.

With a cash out refi, your rate is fixed, but you’re also paying interest on all of those funds instead of only what you draw.

Divide the two and that is CoC return.

I guess for me the dividing line is does it damage the function or cause a safety hazard if I leave it on the tenant.  

Could you share some tips on how to find the builders or is there any platform that I can use to reach out to multiple builders to get quote once the architectural drawings are finalized?

I of course draw a generous salary as I am running the biz right, what $10m a year seems fair right, lol.
