I've seen multiple sites that allow to fill out all the paperwork and submit it to the appropriate states.

You have to fill out some paperwork with the housing authority (at the very least, a direct deposit form :D ), but the list of reason why you wouldn't be able to have them as a tenant is REALLY short.

Most rent control offices probably couldn't even keep up with all the paperwork if landlords really followed all the rules in the ordinances.One other thing to be careful of is getting caught with an ordinance change.

Here's my question: since I'm a "newbie", do I need to have a lawyer reviewing the paperwork on the note(s) or is it something I could do on my own?

Plan to not send any offers because you won't have the paperwork ready.

It takes very little effort to fill out a couple pages of paperwork in order to be in a backup position.  

any investors willing to allow me to review the paperwork from your deals minus any personal information?

Typically you would collect 3% of the PP as a non-refundable option fee then in 2-3 years (depending on your paperwork.) the tenant buyer would get a conventional loan.

The conversion is only paperwork and I've been told that some are doing it as the property is being built. 

If after the 15 day period the tenant decides to not vacate I would then need to file the eviction paperwork along with the $198 fee.
