Seller finance cash out refi

[Logan Privette]

I'm new to the real estate game but doing a lot of research to try and gain the appropriate knowledge needed to be successful. I haven't closed on any deals yet, but have a potential seller finance deal in the works. How do cash out refi's work with those if you were to amortize or a certain period and have a balloon payment at a certain year and want to use a cash out refi to pay off that balloon payment. Or does this not make sense?
