Dear Gurrnett, I would recommend meeting with a financial advisor to discuss your situation.
First: Get a copy of your credit report, and your credit score. Look at the report and see if there is anything you can do to improve the report without spending money - look for mistakes or anything small and take care of them first. Given your financial situation it will take a while to get your score up, but start here because no one will speak with you with a high debt to equity ratio and credit score that's too far under 600-650.
Second: Contact every organization you owe money and try to work something out with them starting with the IRS.
Lastly: If your creditors aren't willing to make new deals with you speak with a CPA, and a credit consolidation agency.
Note: A if you've had this fixer-upper for several years and it's still not complete it might be important to do a risk/reward analysis to see what the return on your investment is versus say putting the same money in the S&P500 (stock market). If it's not earning a positive return maybe it's time to cut your losses, pay off your tax leans, and reevaluate your financial situations and set new achievable goals.
