If it's an investment property you could turn to a "commercial or portfolio" product which is based on the property's cash flow (DSCR) rather than your personal income. 

I'd bet there are buyers for this product in your market too.  

Some providers take the approach that a furnace or water heater with several years of expected life shouldn't be replaced in the rehab, but that the final product should be priced accordingly. 

It's a lot more than just a structure physical build, that's just 1 of about 45 pieces. 

All mail and correspondence will be going to this address and forwarded via email and if necessary, physical pieces to my personal address.

So here's my question stated a couple different ways: - Is the downpayment towards the physical house, or is it for the loan?

I spoke with Zoom and they say CA needs a physical address to form an LLC.

He was great to work with and had an attractive product and clear communication and great assistant that made it all very seamless.

Given your time horizon, your lender have a floating rate product [the HELOC] tied to a fixed rate loan, which is a bad idea, never mind the fact that they could call the HELOC at anytime.
