My brother-in-law, a fire marshal, told me that even if the smoke detector is a melted lump of plastic and metal, they can easily determine if it was operational at the time of fire. 

Are concrete footers the strips of concrete I see in mobile home parks sometimes that  are about 2 feet wide and 80 or 90 feet long... and the edge of the mobile home (the metal frame or chassis) is placed on the footer?

Banks typically lend based on secured assets, (owned real estate, precious metals, stock portfolios), etc.  

Depending on where you are you can change the facade with wood, metal, plants.

My AC guy showed me years ago to check the date the AC was built on the metal tag with the specs.

For $3k out of pocket along with my insurance I can have a metal roof installed.

There was a fire escape staircase for the upstairs unit that was made with wood( not metal that was about to fall apart.

Bought a used stove recently bc the tenant's kid kept breaking the plastic handle on hers and the metal handle ones are way more expensive. 

There is one electric pole connected to both a metal building and a manufactured house.
