"Subject to" insurance issue

[Cha Yang]

Hi BP, Just wondering what your thoughts or what you have done about insuring properties taken "subject to" in the twincities? I have a property that I go via Sub To back in august. I had the sellers keep their original policy and add me as additional insured to avoid due on sale. Now the Insurance company want to cancel the policy because the sellers are no longer the owners of the property. Should I just get a new policy and add the sellers as additional insured or should I get a policy and not add the sellers? Trying to minimize the possibility of Due on Sale as much as possible.
