Rust repair question

Hi,
Wondering if anyone on here knows how much work or cost would be involved in fixing the rust on this car, enough to pass inspection (it doesn’t show it very well, and I haven’t looked at it yet, but seller said there are actually holes)

If you really want to do rust repair then it is like around $500, but i guess most of the time is waste of money because the areas that develop rust spots are more harsh environment.
