The condo was rented successfully for 5 years but is now occupied by my mother so the rental income is no longer there (gotta take care of those that took care of you!). 

It has two house on the property one is a mother in law suite.

30 days sound more like traveling nurses or the like, not a vacation rental. 

I also heard having a "mother" LLC owner of other LLCs which would essentially be dedicated to each individual property.

I can always get my mother as a co signer.

My mother is afraid to leave her home in Eugene because of Covid, Antifa, and the homeless wandering outside her house.

The studio mother-in-law is a block structure separate from the main house, so we'd literally have to knock it down, which would make no sense.

It is simply a letter from the current seller (probably need to include the death certificate as well) explaining that she is the executor of the estate and that her mother, the mortgage holder, is deceased. 

I just used google and I called my mothers friend whos a real estate agent.

I currently live in section 8 with my mother.
