Are online lease agreements enough to protect me and my assets? 

There are also agreements in the lease in equal favor of both parties, I cannot disclose for my own protections. 

If something goes sideways, I would be willing to bet 90% of these single owner LLCs formed for "asset protection" would be easily accused of piercing the corporate veil, and collapses the whole thing anyways.Depending on the state you are operating in, even if you use a Wyoming formed LLC, you will likely be required to register in the state you are operating in, which may require disclosure of that information you don't want to give up already - check to see what those states require for disclosures when registering a "foreign" LLC that is operating in the state.Literally no federal income tax benefits to where your LLC is registered. 

If over a year, and especially during a renewal, they have additional protections. ”getting out of the real estate business” in 1482 would mean moving into the property yourself, or renting it to an immediate if family member.

They also run the risks of high levels of regulatory pressure and litigation by virtue of their renting to legal wards who have access to free lawyers and zealous bureaucrats who see independent investors as a crop to be harvested.

@Corey DuranGood insurance will provide you with more protection. 

Qualified real estate attorney, an asset protection attorney, an insurance agent licensed in the market, contractors, and other investors are just some that come to mind.

How are you protected?

It's designed to protect you from sudden and accidental losses. 

@Shawn McKenzieNothing can protect you - you are doing the work so you would be liable.
