Purchase nothing down, balloon payment

[Craig Anderson]

Hi there, I need some help structuring a deal and figuring out my COC. There's a property that I'm negotiating with the owner on seller financing. Here's the deal presented at the moment:

$600K purchase price, Nothing down, 4% Interest, $2800 monthly payment, 5-year balloon. How do I calculate my COC and Cash Flow with the balloon payment in place? Do I just run it like a 30 year loan on these BP calculators?

Any advice would be appreciated.  Thanks!
