In the living room there is a gas log propane system that is completely clean with no black soot on it.

Several years ago when a new survey was done on their property and the property next door, it was revealed that my parents propane gas tank (which was already in place when my parents bought the property) and part of the walkway (ditto) is encroaching upon the neighboring lot.

Gas up all vehicles. 2 bins of food, gatorade, and water. 

I'm kicking myself for not paying more attention in my oil and gas law class!

Always looking for ways to improve the ARV, and have one upgrade that I'm on the fence about.The gas boiler for this 1920's house is pushing 40 years old.  

Possibly see if you can reroute the gas line from where it currently protrudes from the slab by running it along the wall through the studs or along the interior back of the cabinets.

It's not paying your bills or providing your with gas money (your cash flow does that...more on that in a second)...so if you have a use for that equity, meaning you can leverage it to gain MORE investment properties, then who cares what the fees are?  

Maybe you buy your gas with it every week.

Whose paying  for the gas and electric?

A gas line.
