Typical terms for a Seller Financing Deal - STR property

[Chaits J.]

Hello all,

How do you come up with typical terms while reaching out to someone for seller financing deal.

Should i just ask the owner if he is interested and if yes, then submit an offer with terms?

If that's the case what are typical terms. This is a STR property grossing 100K on an average and listed for 550K. I can do a 20% down.
