After you figure  it out, oil based killz does AMAZING things! 

So, I think the hardest part of wholesaling, with a full-time wholesaling business, is keeping a good team in place as well as having a killer automated and well oiled system in place to handle the volume that is required to scale = make a living (we use Podio and it is AWESOME).  

If you were burning fuel oil or coal or something like that stainless steel would be required but for natural gas you can use either material.

We retiled the fire place surround, oiled and conditioned all the wood paneled walls, and replaced all lighting fixtures.

As Paul mentioned, there are refineries and other oil/gas related industries, but there are also a lot of high tech and aerospace companies that are either moving here or expanding existing facilities.I often talk to a lot of tenants who moved here thinking it was going to be a "cow town" with little to do and then don't want to leave as they find out what a great place to live it is..

had to... also read that the reason OPEC was not cutting production is that they are thinking oil may not go back up so they are dumping all they can at $40...

About a year and a half ago the oil prices crashed and a huge number of folks in my state lost jobs and even tenants of mine have lost oil field jobs or had wages drop pretty hard. 

Oil back up to about $90/barrel. 

Have you considered exchanging some into DSTs to use up debt while putting some cash into gas and oil mineral rights funds to move some of that cash flow to passive sources?

If you happen to know somebody that does steel fabrication or repair work for commercial construction, big boats, oil and gas, etc, ask them what wheels they like and where they get them.The best thing a cheap wheel can do is wear down too fast; the worst thing it can do is shatter and send pieces everywhere, including into you.Also, before you start, check the max RPM of your grinder (it is written on the grinder) and compare that to the max RPM of the wheel (written on the wheel).
