If your question is WHAT IS a monthly homeowner fee? The answer would be that the fee is for an organization set up to attend to community management matters and issues. An HOA takes managerial and financial responsibility for community matters like ground maintenance, exterior maintenance of common property (siding, roofs, pools, tennis courts, etc.).
Hope that helps answer your question. If not, let me know more specifically what your question was.
