Questions - I want to sell my duplex and offer owner financing

[John Meurer]

I want to sell my duplex and offer owner financing.  

Location Milwaukee, WI

Where I need feedback is...

1.  If I sell the property and the buyer occupies one of the units.  Do I need an RMLO (Dodd-Frank)?

2.  If I sell to an investor that will rent out both units (not reside in the property), than no RMLO is needed, correct?

3. I want to protect both myself and the buyer.  I need recommendations on the process when we agree to the sale price.  (i.e.: get a real estate attorney to draft the promissory note and mortgage, close at a local title company, etc.

4.  I want to collect property tax and insurance each month from the buyer to ensure these items are getting paid.  Can I do this?  Do I need to use a special account to hold these funds (escrow)?

5.  This property is owned by a single member LLC I created.  Can I write up the contracts with the LLC as the seller or is it better to sell in my personal name?

Thanks for your feedback.
