What is the difference between Hoitovastike and Rahoitusvastike?

I am thinking about buying an apartment in Helsinki. I'm very fortunate enough to have enough money to pay all cash for the "debt-free" price.

I sort of thought that rahoitusvastike was to pay off the debt if you pay the Myyntihinta and not the Velaton Hinta? But thought I should ask the kind folks of reddit before making such an assumptions.

So if I am able to pay all cash for the entire velaton hinta up front, what would my total monthly responsibility be based on the numbers in this picture? 313.6 € or 718.08 €?

Thanks for your help!
