How to benefit from super low mortgage rate?

I secured my non-assumable jumbo loan at the bottom of the market at a 2.1% 30 year fixed rate. Our circumstances have changed and we may be selling our house in the near future. I am not going to rent the house out  

Are there any creative deal structures that would allow me to pass along this low rate to a future buyer and thus fetch me a higher sales price? Of course I need to be careful not to trigger the due on sale clause.
