it never hurts to negotiate

Some might worry that the employer will cancel the offer if you negotiate. 99% It won't happen unless you negotiate the very wrong way. Worst case, they won't raise their offer, but it does hurt to ask.

In my most recent two jobs, both hiring managers have to get extra approvals to raise their budgets to meet my requirement, so never take an offer without even trying to negotiate unless you think it is really a fair offer.

Good luck!
