Purchase price: $900,000 Cash invested: $600,000 Purchased an existing short term rental fully furnished using equity from existing home here in Los Angeles.

For example, I have a potential client that has decent unit with a solid location but the decor/furnishings remind of a frat boy out of college meets IKEA/Amazon.A unit like this will suffer from poor design and the reviews will show as well which I do not want affecting my reputation or Super Host status.Do I just decline taking them on if they are not willing to work on it?

Be careful when used Furnished Finder. 

My fiancé is an interior designer and her friend from Las Vegas just bought an STR they hired her to furnish this summer.

And if the home is on septic, get that inspected too.Fully furnished: Most of the time that means you've a few things worth using, perhaps bed frames and such, but still a ton to replace.

Should I advertise is as a furnished LTR?

Also, if it is not furnished, that's going to be an issue.

I am considering turning my primary residence into a medium term rental within the next 6-8 months, since it is already furnished.
