Proper notice is a real sticking point and over the last 10 years case law has rapidly evolved  concerning overturning sales due to notice issues amongst other factors.

One benefit of an HOA having established rules is that for any changes to be made requires a 2/3rds majority vote of the residents to overturn rules.  

One or the other could possibly overturn the sale. 

IN MD the former owner has a statutory right to challenge within 30 days and deliberate fraud must be proved to overturn after a year. 

Any decent judge would overturn that deposit deduction.

Many tax deed states have allowances for the sale to be overturned if it was held improperly (without proper notice, or if there was a mistake, etc.), so regular title insurance isn't available.

They are quite common in FL Foreclosures....never seen one actually denied/overturned.

@Rob Bergeron any new details about what is being done to overturn this.

@Don EnriqueIf the notification is not done correctly, many states allow the foreclosure to be overturned. 

Something that may have been legal in June could easily be overturned by late September.
