Block construction is solid (better than metal but not as desirable as concrete tilt), im assuming it was built in the 70's?

I can easily vent it to the outside now using rigid metal duct.

Oil, precious metals?

Do you wish to be a lender, operate rental property, purchase stocks, metals, or any other of the multitudes of possibilities?

@Nathan Adams Unless it needs to be painted there is not much you can do other than paint...not sure but maybe a clean light gray.Some older 1960’s condos here built bIg planters out of wood and galvanized metal...very cute.

I do appliance repairs, electrical and plumbing work, roofing, pest control, metal and wood fabrication, etc. 

Especially on the farm when I need to cut some metal away from a power supply which is 80% of the time.

@Hank Keller As I dig further and further into Real Estate Investing, I keep hearing advice, not to invest in anything other than precious metals bc we are set to have a shift in the next few years.

Spray, or a metal device, or is there something new on the market you can suggest ?
