Unless the rules are very different in your state, the seller is free to reject any offer she wants, especially given that it isn't full price. The repairs seem fairly minor, so the big question is what do the comps say it is worth? The asking price is only a starting point and may or may not reflect reality. Our seller refused to fix anything, but we felt that the house was still worth what we had offered and went ahead anyway.
Good luck - I hope things work out for you and you find your dream home :-)
