I am not doing this for asset protection or any other reason - just as a way to demonstrate that I manage properties in addition to our own and to count those hours of activity. 

It is probably the best for asset protection, but do you want or need that full protection or is that something that you want to build over time and can accept to have a lower level of protection for now and just create the corporation and one or two LLCs.Again, it is your choice.

Most individuals put properties under a LLC for tax, asset protection or organization purposes. 

It's not just about 100% asset protection or 100% anonymity, those are almost impossible.

Even "tax attorneys" are typically attorneys that defend you against IRS audits and lawsuits, not typically people you want to go to for specific tax advice.As @Logan Allec said, you want an attorney for forming business entities like LLCs for asset protection, or for drafting any contracts or agreements necessary for your flip business (partnership agreements, etc).

Do you have protection? Or

Asset protection or accounting purposes?

Since Trust documents don't need to be filed, they won't know...Are you trying for asset protection or to "hide" from your tenants so they just don't show up on your doorstep? 

And lastly do you recommend using LLC for asset protection or is it too much of a hassle?
