I would expect him to respond based on what you said.

Did it meet your expectations, fall short, or exceed them?

We run calculators on what you can expect for expenses beyond your mortgage, I don’t like surprises.

Still wouldn’t have expected it to be such a failure like that.

Now my expectation is that I won't leave more than 12-15% of my investment in the property after the refi.

What's the life expectancy of the roof, paint, furnaces, water heaters, etc.?

Anywhere from $500 - $2500+ depending on the insert you install and whether you run the vent and exhaust up the old flu or cap the flu and vent/exhaust through the side of the house/chimney.If you hire out the entire job, expect to be in the $1K - $1200 range.

I don't think it's expected nor do I think it will get you extra business or higher rated reviews.

Without knowing the specifics of the neighborhood or property I would expect it to appreciate the same as other 1-4 units in the area over the next decade.

Let your tennant in the “disuputed” unit know what’s happening and discuss temporary solutions in case this drags on longer than expected.
