@Nathan Goodlove I'm not sure if it's necessary to use an attorney as a registered agent, but it's probably a good idea to consult with one before you attempt to do something inherently legal such as asset protection.

Anyone know where we can obtain all the forms we need without having to pay $$ for them? 

Are you even going to be credible for a $500,000 asset?

Turn Key is good option if you want the asset handed to you at market value with no upside.

The plan was to purchase the duplex and than put it under an LLC to protect my asset.

If you 1031 exchange you can buy more passive commercial assets where you do not usually deal with these types of issues.

I am looking to be an asset to the people I’m networking with.

Do you know how to comp a commercial asset?

It's the quality of the asset.

I note that you asked specifically about “cash-flows”, which has multiple components each treated differently for tax purposes.In general, you can start with NOI, next you have debt service and cap ex, which can get you to cash-flows.The interest portion of your debt service is tax deductible (possible subject to limitations) and the principal portion is not because you get basis in the asset for the loan principal, which generates a depreciation deduction.Similarly, cap ex is generally not deductible currently but the expenditure is capitalized and depreciated, similar to the initial basis in the asset.In summary, you have cash and non-cash tax items that cause your taxable income to differ from your cash-flows and taxable income * tax rate determines your tax liability.
