Help with inspection summary for duplex house hack in contract

[Jacob Northfield]

Hi everyone, thank you all for your help so far. This forum is priceless and I am really enjoying soaking in as much information as I can. 

Monday was the inspection for a duplex I have under contract. The original asking price was $179,900 (this is in the South Wedge, in Rochester, NY), and my offer was accepted at $152,500, but after seeing the inspection summary I am having second thoughts. There are several issues which I'm concerned about, and since I'm not handy and this is my first house, I'm a little apprehensive. Here are some things that were found:

1. The driveway needs to be resealed.

2. Wicked overgrowth on the garage and garage roof, as well as moss on both the garage and house roof.

3. Gutters need cleaning and repair. 

4. Siding may contain asbestos and is chipped/broken in some areas.

5. Evidence of bees in the siding trim.

6. Hole in the garage roof about the size of a basketball.

7. Garage car door and side door needs to be repaired/replaced.

8. House roof has weathered ridge cap shingles.

9. No attic access so we don't know what's up there.

10. Wood rot and moisture damage found on outside of the house.

11. Plumbing leak in the basement actively leaking onto floor.

12. Basement ductwork has asbestos tape with corrosion and holes in the ducts.

13. Both kitchen sinks are leaking. Looks like someone tried to set up the plumbing themselves and it wasn't done properly.

14. Water heater shows corrosion and poor mortaring.

15. Two condensate leaks were noted on PVC vent pipe. Vent pipe should exit basement further than it
does now before terminating.

16. A double tapped breaker was noted in left service panel box. Several outlets showed open ground or reverse polarity when tested. There were several electric junction boxes missing covers in basement.

17. Not all windows are operational. Many are missing locks and some are painted shut.

18. Evidence of past leaking from the ceilings.

19. Bathroom floor not level (I think it feels rotten but the inspector disagrees).

20. Upstairs dryer improperly vented.

The real estate agent is saying I can fix all of this for myself with about $1,500... that doesn't track for me but I don't actually know anything, so I was wondering if anyone here has any thoughts to share or advice? I like the property, but I don't want to overpay then realize that the damage is worse than they are making it out to be.

Sorry for the long post and thank you for your help!
