Even if bad luck happened to coincide, charging people rent for an uninhabitable domicile is unconscionable in my book. You can have bad luck and still be a good person. And if you're truly running it as a business, you should be mostly covered by insurance.

I believe someone who would charge rent in this situation is immoral and uncharitable. They've sent clear signals that either they value money over people, they don't care to help others when they can, and/or they're selfish. I want no part of that person.
