If you're referring to an increased tax assessment from the city for the value of your co-op (and I'm not certain if you are) then
... these appeals take at least a year if not longer. So even if 2011 is on the outside of the envelope, it's not unheard of. Thre's a saying: "The wheels of justice grind slowly."
... the city re-figures your assessed value every few years, not every year, so in those years when nothing changes, there's nothing to appeal.
If this isn't what you're referring to please clarify.

this is what I am referrring to - the assessment that is effected by the new tax increase. they are claiming it has gone up and that the review will not get "on the docket" until 201 but that it must be paid asap. in the meantime, how much has heating fuel gone down?

Ah -- no, the seven percent tax increase, unlike your assessed value, cannot be appealed (except through the city council) (There's another saying: You can't fight city hall). I don't know what you mean by getting a review on the docket until 201. The rate increase is not an issue for the courts.

And yes, the bill must be paid when it's due. Just the same as when ConEd increases your electricity rate: you have to pay it when the bill comes.

Oil prices are down but how much depends on the kind of oil you're referring to. The price you read about in the newspapers is crude oil: the unrefined stuff that is turned into (or "refined" into) the kind used for heating oil or gasoline. Just as there are different grades of gasoline (regular, super, premium), there are different grades for boilers. So you'll have to find out what kind your boiler burns (typically either No. 2 or No. 6, but there are others). Once you know what you're looking for you can find the answer yourself, if you have access to the Internet (which I suppose you do since you're posting here!) on a commodities web site.

I d mean the assessed value. thanks for clarification. we are disputing the assessed value via and attorney. heating oil is no. 6.
