That will depend on the taxpayer's personal situation.

I do get nervous with finances and want to be financially responsible.

@Denis Orlov I don't do STR, but I've rented one of my personal properties for arbitrage before. 

While an LLC can offer liability protection and tax benefits, it’s not essential for a single property—personal liability insurance and an umbrella policy may suffice for now.

Let's cut to the chase:  "A tenant is obligated to follow HOA rules, as they are considered residents of the community and must abide by the same restrictions as homeowners, even though they do not own the property; the landlord is responsible for ensuring their tenants understand and comply with the HOA rules. 

Was it real property or personal property?

Now, should you decide to enter into a real estate transaction WITHOUT a licensed agent, one should be mindful to not get unpset should that person get scammed in the real estate purchase or sell transaction.

I think I can open another personal checking account at the bank I already have and it'll be under my name but i'm trying to buy out of state rentals with an LLC I own.

Buy a few things on credit that you would just usually pay cash for.I personally would not rush into a Heloc or such.

Personal guarantees are EXTREMELY common.
