Help with seller financing

hi guys-

i found a park where the seller is willing to carry financing w/ 10% down. we both agreed that i would refi and obtain my own financing after one year. the seller is worried that the lender on his underlying mortgage will find out about the sale and exercise the due on sale clause. to circumvent this, his agent proposed a land contract. since the land contract only gives me equitible title (and not legal title)… when it comes time for me to obtain financing, i believe that i will have problems because lenders will want to see that i held legal title (and not equitible title) for at least one year…correct?

how can we structure this deal so that i can purchase this park w/ 10% down…and i refi after one year?
