I've seen allot of back and forth regarding transferring the deed from personal to an LLC. If this is conducted with the intention to execute the transfer without the lender knowing, doesn't the insurance company who holds the fire insurance have to know of the change? Or is it not an issue?

Barring any state reg on the issue, i'm not sure if the insurer is in a much different position than before.   Realistically thought, I'm willing to bet each carrier has it in their policies that they must be informed.  You may give them fuel to deny a claim on this. 

However, in case you don't know, lender can accelerate on the transfer.  Not to mention the tax implications of transfer.  Can't explain fully w/o knowing all the variables.  Best to speak to your CPA.  

Good luck!
