A lot of the Airbnb type of business recommends creation of an LLC for separating personal and business assets.

What are some STR that are not very crowded and there is little to no supply creation?

You forgot friend, consultant, advisor, marriage counselor, psychologist, therapist, errand runner, appointment setter, economist, psychic , taxi driver, cookie baker (open houses), designer, negotiation expert, and probably 100 more....Good luck and best wishes.

Home-buying expert Liz Hutz notes that “the two main drivers of price increases are economic growth and job creation.”

*Quick tip* Prime corporate services does LLC creation with articles of organization, op agreement, and EIN for really cheap if you say you were referred by someone who uses them.

They have user-friendly invoice creations and allows the tenant to pay also by credit, debit, or ACH.

However, It's up to you to be the final judge of whether or not wealth creation is worth it to you or not.  

More tax efficient and a more long-term strategy towards wealth creation. 

"Rich people sell may sell things, but wealthy people never sell anything"Seeking ways to gain equity by leveraging OPM (other peoples money) and not exchanging you own time to do so is arguably the biggest hack in wealth creation regardless of the industry you're in. 

My view on affordable housing is that it benefits too few and has loopholes that prevent wealth creation.
