I have used refinance by choice in recent times (fixed rate versus variable rate but typically the refinance loan has a higher cost) but maybe 5 years ago I looked for institutes that would provide an ELOC on non-owner occupied RE and I found a few but in excess of 90% did not offer the ELOC on non-owner occupied RE. 

I would start looking today, deals don't often pop up for your first time so if you think you'll be ready in Jan then chances are it'll take a few months after to actually get a deal.And finally something I did a little but not too excessively: reverse engineer. 

My guess is that you can find an Excess (aka Surplus) lines carrier for the Vacant building and the Liability.  

I did a final walk through inspection today and the place smells excessively!

If it is a flip and he's bringing the cash but you're doing the labor, I think giving him 50% of profits may actually be excessive.

I'd expect that the excess mileage charges would be a killer.I think next time I'd so something like a Jeep or a Honda SUV. 

The replacement program was initiated because certain fire extinguishers can become clogged or require excessive force to activate, posing a risk of failure to discharge.

I would only pay the mortgage off with excess cash flow that was not needed for the running of the asset.. if your making a few hundred a month positive whats that going to do for you mine as well pay it down so you don't just spend the money on dinner closes starbucks etc. 

Umbrella insurance will cover up to certain amount, like mentioned in the other article I find it hard (for myself) to see how I'd be sued for something in excess of the appropriate insurance coverage.

We BRRRR the properties (or hold them free & clear, depending on investor's preference), return the invested capital and split any excess in the refi 50/50.
