Billings is unique as it is largest city, it also gets some impact from ND oil boom (then bust, now starting to boom again). 

The house has a Hugh oil tank in the basement.

I'm not concerned with the apartments not being separate (as they fit the description of a multi-family), I'm more concerned of the zoning laws in that part of town.We are converting from oil to natural gas and had an inspector come in to sign off on the install of the gas heaters in order to get 2 meters from the gas company to have heat/hot water.

It's very common for philly investors to pay for the water, and pass on oil, electric, etc to the tenants.

As a wholesaler, people set up a well oiled machine with data, systems, and a VA for <$2k/mo.

There's nothing wrong with hiring someone to change your oil any more than it's not wrong to hire someone to mount your sink.Between my wife and I (pretty much just my wife), we can usually DIY if needed, but it's always harder, sloppier, and more time-consuming than if we could hire a contractor. 

If you are exposed to oil and gas, things are looking up.

GE OIL and GAS came in as well and much more.

Oil price is supposed to be where it is after ups and down and puts oil companies in good place.

In combination with a gross rental yield of just under 2,2% it's not worth the risk or the return.The Norwegian market has been driven by low interest rates and an oil driven optimism.
