Hi, I just saw your question as you've been waiting many hours for a reply. Although I don't know what state you live, most bankruptcy laws per state are generally the same. Here is what I've found for you:
First, I suggest you seek counsel from a bankruptcy attorney, however, you can only file chapter 8 bankruptcy six years from the date of your last chapter 7 bankruptcy. You can file a chapter 13 case every six months if you have to. For further reading, click the link below. http://www.carlisleandcarlisle.com/bankruptcyinformation.htm
A bit more about Chapter 13
Chapter 13: Ch.13 involves implementation of a wage earner's plan, and is mostly filed to stave off a foreclosure of real property or any property where a lien exists. This type of bankruptcy enables the filer to first channel payments exclusively and only to a secured creditor(s), and only after those payments are satisfied, to make payments to unsecured creditor(s). Ch.13 bankruptcy generally takes 3-5 years to complete.
How many times can I file?
This depends on the chapter you are filing: One may only re-file under Chapter 7 six (6) years after those debts included in a prior Chapter 7 filing have been discharged. For Chapter 13, there is no prohibition against re-filing after the prior Chapter 13 filing is complete. If you have filed a previous case that has been dismissed, you may be able to re-file but could face sanctions from the court if you do so without good reason or a change in conditions since the first case was dismissed
