Seller financing deal

[Ryan Hesselberg]

Hey! I'm looking to purchase I multi use building that has value add. Seller wants 200k. He had a couple agents lol at it and guess is worth 150k. Seller said he may be open to seller finance. I'm thinking of giving him what he wants (200k), as long as he accepts my terms of 0% interest and zero down. I figure if I were to get a 150k loan for 30 years at 4% with 20% down, I'd end up paying 206k over the life of the loan anyway. So he gets his 200k and doesn't take the tax hit up front and I get a low payment and keep my capital, which will help me fund the rehab. What am I missing? Thanks!
