All good advise here. How long have the seller and HOA been negotiating? In my experience the HOA will usually accept 1 year's overdue HOA fees.
I would suggest you find out how much the difference ind...and ask your Realtor or your Attorney to offer a portion of what is considered 'due' in your behalf...if you feel the property worth it !
Good luck and focus on your goal!
