My question is such a setup valid?

Quote from @Karolina Powell: @Richard Volkov, the oil and gas industry has something like this. 

Your concerns are completely valid. 

Water, power (no gas) are billed directly from the utilities company. 

Oil and gas wouldn't be what it is without the government taking on much of the risk through the intangible drilling costs tax credit, and the depletion allowance act deductions, and literally hundreds of other tax benefits, loopholes and direct subsidies plus the fact they have access to public land to be drilled for pennies on the dollar, and the government cleans it up once they're done. 

They can return the dryer and purchase a gas one. 

I own a multi-family house that was converted from a single family, therefore, there is only one gas meter.

I’ve come across details regarding the Prohibition on the Purchase of Residential Property by Non-Canadians Act, and it seems there are exceptions for buyers with a valid work permit or for properties outside Census Metropolitan Areas (CMA) or Census Agglomerations (CA).Do you know if certain types of work permits are more favorable for this purpose?

But in the South contract for deeds are not liked by the RE attorneies, where up north CFD has state statute validity (which states?). 

Florida statute is clear, upon receipt of a valid permit application, the building department must issue the permit or deny it with valid reason within 30 business days.
