The only correct advice is, "Go talk to a professional."

If Im understanding correctly, youre buying the home from your mom who will take a first position lien on the property in exchange for carrying the $100k of the purchase price on a private note.

Start early, raise that equity well in advance, and make sure all those forms and verifications are filled out correctly.

@Daniel Tanasa   Unfortunately that is not correct when it comes to mortgage debt.

There could be a million reasons as to why you didn’t achieve that goal, but course correct and get it next year!

Keeping insurance and ownership in mind, what is the correct day to start the lease?

However (to go into detail requires a separate post), that's not quite the correct course either.

@Shawn SheedyIf I understand you correctly it appears you are expecting a property owner to subsidize your rent at a below market rate....which in essence means you'd be digging in their pockets, not the other way around as you have accused.I don't see how the effort to enact laws after the fact changes your current situation. 

Very few people operate their LLC correctly and therfore this just gives them a flase sense of security.Moving into a LLC can also trigger the due on sale clause.

Correction, I just re-read my notes from last October.
