What are my best options for getting my home forclosure be resolved?

My house is in foreclosure. I am prepared to reinstate the loan but when I requested the amount, the fees were $5,000. I am only $7,000. behind on the mortgage. I was surprised to find out that reinstatement will cost over $12,000. In addition, for the past 6 or so years, I have had an issue with the bank not paying my taxes so that the house goes into tax sale and I end up owing fees related to that. I have been unable to get the bank to resolve this issue. I have had my house for 17 years and the original amount financed is only a few thousand more than I currently owe, I think from these fees.
