Quote from @Ryan Grise: Check your state law to see if there are specific requirements.

I own a house (NW Indiana) that I fully renovated and now have 200k equity in it.

Or do tenants pay for their own utilities?

Ideally the rent from the other three units will cover most of your living expenses (ie 'rent') for your own unit while you are living there.

The plan is to cease the STR next year and switch to a MTR and thus, I would then report that property on Schedule E.My other property, which was also recently acquired, is already a MTR, and I would need to report it on Schedule E.So my question is: can I report one property on SCH E and the other on SCH C even though they are both owned by one LLC?

In Salt Lake City, you don't even need a business license to rent out rooms in your own primary residence.What are my liabilities renting without a business.

Own rental property2.

I could not use my own document.  

Focusing on individually owned properties with no more than one mortgage and at least 10 years of ownership should help you find places with good equity.

Are you wanting to own your own home somewhere else?
