If you may want a variable amount to do renovations or furnishing and may be able to pay it down quickly or refinance down the line, a HELOC might be better.

I have a property in Coral Springs Fl that’s fully furnished and turnkey I’m looking to rent long term $7500/mo.

Furnish a property and rent it as an STR or MTR.

It generally relates to "Hosting" on AirBnB and VRBO, AKA furnished Short Term Rentals. 

I know airbnb, Vrbo and furnished finder but not sure if there are any other places people have them listed?

I've looked at duplex and triplex arrangements and even furnishing attics and basement potential value ads, but most of the time the purchase prices still make cash flowing a house hack seem difficult.

If you can find/have the money to furnish/decorate it well a STR will almost certainly do better than a long term rental. 

Keep your furnishings to an absolute minimum. 

Unfortunately, sometimes, some people (With limited work/life experience) may not understand that you have a right and they have an obligation, to furnish the demand to you and as a result, force you to to stupid things such as get a borrower's authorization to release information on a property they no longer own. 

While I was searching for room prices in the area that I plan to invest in, I realized that over 80% of the listings were furnished.
