When I was working in Maine and NH, I recall petrol stations dispensing both kerosene and furnace oil (really diesel) and folks buying 5usg  containers to heat their homes for the day.

The key is a good team or if your buying near you just make sure your offer contains a good inspection and due diligence period.

Now, I'm just a stupid tile guy who installs the stuff, but my wife is a potter and actually makes all kinds of ceramics, including tile.

Very interested in venturing into shipping container self storage.

Has anyone been able to build a non-traditional house (storage container, tiny home, modular,etc..) and have it pass under-writing standards?

My wife recently purchased an 8000 watt electrical ceramic kiln, 240V 1 phase power, 33.6 amps.I am installing in the basement of my home (owner occupant, not in a municipality that requires an electrician's license):1. 50 amp dedicated breaker in the panel, per kiln manufacturer's recommendation.

Depending on the quality of the property, location, and tenant history I would consider upgrading to ceramic tile.

I use RTAs from Kitchen Cabinet Kings.Flush hot water heater between tenantsUse drain enzyme to clean out drains between tenants to clean old plumbing lines.Use a powdered boric acid based bug killer before tenants move in to keep bugs in check.Use stainless steel and ceramic for sinks.  

I know the process is significantly more intense if the current paint contains lead.The kit I used is supposed to turn red in the presence of lead. 

If they could get out of their own way of their own regulation or reduce them for developers and charities to be able to build housing from say shipping containers,  or in older commercial buildings without having to do a full upgrade to modern standards.
