@Marian Smith The facts are still the same.These regulations seek to deny the owners of their own private property the right to use it as they see fit.If they were putting a scrap metal yard or a pig farm in the midst of a residential neighborhood, you might have a valid point. 

.- On more than one occasion I have seen homes that were updated and between tenants get ripped and stripped of all the copper and for $30 worth of metal, the thieves caused $10,000 worth of damage.You will find that in better areas, this does not happen as much, but it still happens.  

Metal water pipes start filling in as they get older, check the water pressure to see the condition of the pipes and for leaks and don't forget to check for leaks in the drains. 

As we were flipping, we met ALL of the neighbors because they saw us working and wanted to know what was going on.

Have any friends that play the drums in a metal band or belong to a biker gang?

Two options you might consider: First, precious metals.

After you solidify the business side then go into either information on metals or the bond market.

The wall cabinets (upper cabinets) are much easier to install because they run along one metal rod.

Of course, it takes two to tango...you've got to be worth the metal you're stamping.

I also listen to your so called dooms day economists (like Peter Schift and Simon black) to have a broader view of the world.It is your choice to listen to all information and make a decision or to ride your unicorn that farts rainbows.You said you have not heard any one of these dooms day economists recommend what to invest in which surprises me since they are all saying to get into precious metals.
