Need help understanding seller financing terms

[Tessa Rysztak]

This is my first "real" post.  I hope I'm putting it in the right place!

Im looking at starting out with a few small multi family investments, with seller financing. Right now, I'm working off the MLS. One of the homes I am interested in gives the financing terms right on the listing. It's listed at $39,900. It doesn't say what the rents are currently, so I know that I would need to find out that information if possible.

The terms listed are "Land contract options available ($5000DN/7.5%/$750.00/3yr payoff) Subject to buyer's credit report and/or proof of funds". Is the $750 they are referring to the payment they are looking for?  I can't figure out how they are coming up with this amount, if that's the case.  I'm hoping someone worth more experience can shed some light on this for me.

Thanks!
