I am guessing lighter and something in a can that can combust.  

What are some ideas on how to use this in terms of scaling my rentals properly What I learned from the LOC I had back in the dot com bust is that the bank can close it on a whim.

Of course insulation is made to not be combustible but there is still a risk there that should be addressed.

Where the application of a new roof covering over wood shingle or shake roofs creates a combustible concealed space, the entire existing surface shall be covered with gypsum board, mineral fiber, glass fiber or other approved materials securely fastened in place.1511.5 Reinstallation of materials.

I myself went through 3  1989 to 1992  SF BAy AREA  dot com bust Bay AREA  it was a little one.and of course the mother of all of them the GFC of 07ish to 2011... and I am sure Charlie based in Vegas had to work through problem loans.. and we just don't need the practice anymoreAs to regulations its just no fun for me anymore I put my NMLS license on ICE and anyone who does business with me we do it as a JV partnership..

(Excludes concerns about combustion and vaping indoors)it's legal here in AZ too.

My own home (which I recently sold) has a gas stove so I ran a wire and installed an electric so I wouldn't have products of combustion in my house.So... this is a good thing.

The remaining funds are being invested in Toyota plants in Kentucky, Missouri and Tennessee.This new investment will help the Huntsville plant develop a new four-cylinder production line with the capacity to produce engines that will suit combustion and hybrid electric powertrains.

Tankless water heaters are also supposed to de-scaled/cleaned yearly with combustion anylasis done to check efficiency. im a plumber and have a power vent in my house.

I have had a heloc for 25 years and have used it as needed.In the 90's we had the dot com bust, mostly affected Silicon Valley where we lived, and we almost had to sell a property to generate some cash.
