Title transfer to avoid the lender to call the loan

[Mary Jay]

Hi guys, 

so we purchased a property in my boyfriends name, my name is not on the loan and not on the lien, however we were buying it together (put the money together ) and we want to own it together. His mortgage company is transferring the loan to Penny Mac, when is the best time to put the property into an LLC ? ( the Llc belongs to both of us)

Is it better to do  the transfer to the Llc after the transfer of the mortgage from his mortgage company to Penny Mac? 

Since I am not originally on the title and nor am I on the loan, we are worried about triggering the due  on sale clause. So what is the best way to transfer the property to an Llc  without triggering it?

Should we wait after the transfer to Penny Mac is complete? Or better to do it now while the transfer is happening?

Thank you
