presenting a no money down land contract to a bank?

Hi All. I just “closed” on a no money down land contract on three duplexes with a seller that was willing to accept a purchase price of approx 80% of market value (he wanted out bad). He has a mortgage on the properties so basically I assumed his mortgages without the lender knowing (I send payments directly to the seller), the expectation is that I would refinance right away and that’s when he gets his purchase price. I called one bank and explained this exact scenario to them and their response was “we can do that” but they didn’t agree on the market value of the property so I tried another bank who said “we won’t do that b/c we don’t like no money down deals- no skin in the game”. My question is: without lying or trying to mislead the next bank is there a marketing “spin” I should put on the situation when calling and asking if they’ll do it? Thanks so much!
