our community has a HOA.  a necessary evil.  now its necessary.
a family moved out of a house over a year ago for financial reasons.  the home is still in their name.  they cannot be located.  anywhere.  event the police cannot locate them.  the bank will eventually get around to completing the forclosure, and taking the property out of the old homeowners name.  The house was left in shambles.  filled with garbage and old belongings, old food, furniture, rodent feces, etc. the garage bays are broken, and are a invitation for squatters.   this house continues to deteriorate, does not meet hoa  standards, and is directly effecting the home values in our community.  
can our HOA, based on Abandoned Property/Abandonment sections in our HOA bylaws, take legal action against the bank, to complete the forclosure process and force them to maintain the property based on our bylaws?
