how expensive is hard money?

[Devin Mann]

say they are offering 4 points with 12% interest on a hard money loan and they are offering 70% of arv.

this SFR is worth 300k ARV. Im purchasing it for 170k. Now how do the costs lay out? i pay those 4 points up front or at the end of closing? and how much would my interest only payments be?

i know its a dumb question, im just trying to figure out how much money i would need to get a hard money loan
