I bet it will do well for you if you can find a contractor to help you out. 

Your best bet is to find some local meetups while you are reading about investing in books and on the forums.

If you have a 2.4% rate on your first, a 2nd lien or HELOC is likely going to be your best bet to access the equity without incurring higher rates via a refinance. if you sell you wouldn't be buying a "second" property anymore.

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.
