Section 2435-B. Tax lien purchase and sale agreements

(1) In order to
  fulfill the purposes of this title and  to  provide  a  means  by  which
  municipalities   may   collect   the  moneys  necessary  to  fund  their
  expenditures and provide revenue to fund any other  lawful  purpose  and
  notwithstanding  any  general or special law to the contrary, the agency
  or its tax lien entity and any municipality  are  hereby  authorized  to
  enter  into one or more purchase and sale agreements for the sale of tax
  liens by such municipality and the purchase of such  tax  liens  by  the
  agency or its tax lien entity, which purchase and sale agreements shall,
  consistent  with  the  provisions  of  this  title,  contain such terms,
  provisions and conditions as, in the judgment of the agency or  its  tax
  lien  entity,  shall  be  necessary or desirable. Each purchase and sale
  agreement  shall  specify  the  amount  to  be  made  available  to  the
  respective  municipality  from  the  proceeds  of  an  issue of tax lien
  collateralized securities which amount may be more or less than the face
  amount of the tax liens purchased by the agency or its tax lien  entity,
  and  any  other  amounts  which  may be made available to the respective
  municipality on a contingent basis under the terms of the agreement.  In
  addition,   each   purchase   and   sale   agreement  may  require  such
  municipality, subject to appropriation by  the  appropriate  legislative
  body  of  such  municipality, to make provisions for the payment of such
  other fees, charges, costs and other amounts as the agency shall in  its
  judgment determine to be necessary or desirable.
    (2)   Any  purchase  and  sale  agreement  entered  into  pursuant  to
  subdivision one of this section shall provide that the obligation of the
  municipality executing such purchase and sale agreement to fund  or  pay
  the  amounts  therein  provided  for shall not constitute a debt of such
  municipality within the  meaning  of  any  constitutional  or  statutory
  provision  and  shall  be  deemed executory only to the extent of moneys
  available and that no liability shall be incurred by  such  municipality
  beyond  the moneys available for such purpose, and that any such payment
  obligation of such municipality other than the  timely  payment  of  any
  moneys collected by it and due to the agency or its tax lien entity as a
  result  of  the  redemption  of  tax liens which are the subject of such
  purchase and  sale  agreements,  is  subject  to  appropriation  by  the
  appropriate legislative body of such municipality.
