Appropriately Insuring House with Wrap Around Mortgage

[Cliff T.]

House was my primary residence, then rental. When I sell it, I will keep my mortgage on the property and owner-finance it to the buyers.

This generates at least an extra $50k+ on the deal in interest, but even my own insurance company isn't sure how a claim would be handled.

I HAVE to keep my insurance policy on the property according to my lender. Should the Buyer get a 2nd insurance policy on the house?

Or should I charge the Buyers the amount I pay for the policy, instead of them getting their own policy?

My insurance agent has no idea how to deal with a wrap around mortgage... Who here knows the best way to proceed?
