Seller finance opportunity

[Kevin Akers]

I have an opportunity to purchase 2 units. The seller likes the idea of doing seller financing. Since I be house hacking I would rather just purchase it from him since my monthly expenses would be lower. If I did end up doing seller finance, what costs am I expecting when I refinance the property for a longer fixed rate term? I know closing costs is one of them. Just trying be proactive and know all my solutions.
