How do I handle a landlord back billing large lump sum for overages?
Its a difficult question without reading your lease. Are you responsible for the utilities? If so what does your lease say as to the amount you must pay? How often must he give you an accounting of the utilities? If there are actual overages you should ask to audit ALL of the bills AND ask him to give you an equal time to pay them (e.g. spread the payments out over the period he did not audit).
