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.

The delays you mention seem excessive, that said, if the delays are due to the local utility company (some are common but not that long) then you don’t have a lot of options but I am feeling like the contractor here has caused at least some of the delays.

It's possible that your agent wasn't aware of some of the charges that would be in the closing costs like the upfront mortgage insurance premium.There might be some excess things in the estimate.

If the regular market will not cover it, have your agent check in the Excess/Surplus lines.
