We purchased a 2nd lien, and by the time it was transfered, we passed the date to file as a secured creditor due to the prior servicers attitude of most will not make it through CH 13, and they are over 2 years into the Ch 13 plan.So we are unsecured and have to wait for it to be dismissed, and we can't foreclose since they are in Ch 13.

You’d have to transfer title to yourself, finance in your own name with personal guarantee, and then transfer title back to the LLC, in order to make that work.  

They said it could be transferred to an LLC once the HELOC was complete (but doesn't that then activate the "due on sale" provision in the loan?!!).

Occupancy is key but if you get relocated  again, you can at that time of transfer, retain the loan and airbnb or convert to a rental.  

As far as timing, they were quick to get the LLC set-up (under two business days), then it was on me to get funds transferred from my 401K and get my LLC bank account set up. 

In Pennsylvania, for example,  you will generally want to form the LLC well before you enter into an agreement of sale due to realty transfer tax concerns. 

The deed transfer alerts them. 

"Assignment" is just a legal term for transferring your rights in a contract to another party.

Yes, the concepts definitely transfer.

I wonder if I want to transfer the property I am buying under personal loan to LLC.
