(b) The aggregate amount of each such  participation  loan  shall  not
exceed  the cost of the rehabilitation, conversion or construction, plus
the costs of  any  or  all  undertakings  necessary  for  the  planning,
financing,  acquisition,  satisfaction  of tax liens and other municipal
liens and  encumbrances,  construction,  equipment  and  development  in
connection therewith, provided that, if any portion of such loan is used
for  the  cost  of  acquisition  or  for  refinancing,  the  amount of a
municipality's portion of such loan shall not exceed  one  and  one-half
times the cost of rehabilitation, conversion or construction.
  (c) The amount of any such loan, together with the amount of all prior
liens  and  encumbrances, shall not exceed, except in the case of a loan
made to a non-profit company, a mutual company, or a housing development
fund company, ninety per centum of  value  unless  the  agency  makes  a
written  determination  that the owner has insufficient resources to pay
for the remaining ten per centum of value, in which case such loan shall
not exceed ninety-five per centum of value. The amount of any such loan,
together with the amount of all prior liens and encumbrances, made to  a
non-profit  company,  a  mutual  company,  or a housing development fund
company shall not exceed value, provided that when after  completion  of
such  rehabilitation, conversion or construction, such multiple dwelling
is, or is to be operated, exclusively for the  benefit  of  persons  and
families  who  are entitled to occupancy by reason of ownership of stock
in the corporate owners, such loan shall  not  exceed  ninety-eight  per
centum of value unless the agency makes a written determination that the
owner has insufficient resources to pay for the remaining two per centum
of value, in which case such loan shall not exceed value.
  4. Each such bond or note and mortgage or bonds or notes and mortgages
shall  be  repaid over or within a period of thirty years in such manner
as may be provided in such bond or note and mortgage or bonds  or  notes
and  mortgages  but  in  no  case shall the term of such loan exceed the
probable life of the multiple dwelling which is hereby determined to  be
thirty  years.  Such  bond  or  note  and mortgage or bonds or notes and
mortgages and  any  contract  in  connection  with  such  permanent  and
temporary  loans  may  contain  such  other  terms  and  provisions  not
inconsistent  with  the  provisions  of  this  article  as   the   local
legislative body or the agency may deem necessary or desirable to secure
repayment  of  the  loan,  the  interest  thereon  and  other charges in
connection therewith and to carry out the  purposes  and  provisions  of
this article.
  5.  The bond or note or the bonds or notes issued by the owner and the
mortgage or mortgages relating thereto may authorize  such  owner,  with
the  consent  of  the  agency  and  the  private investor, to prepay the
principal of the loan subject to such terms and  conditions  as  therein
provided. Such bond or note and mortgage or bonds or notes and mortgages
may  contain  such  other  clauses  and  provisions  as the agency shall
require.
  6. Where a municipality joins with one or more  private  investors  in
making  a  participation loan secured by a single participating mortgage
or by separate mortgages, the agency may make provision, either  in  the
mortgage  or mortgages or by separate agreement, for the performances of
such services as are generally performed by  a  banking  institution  or
insurance company which itself owns and holds a mortgage or by a trustee
under  a  trust  mortgage  and for the imposition of reasonable fees for
financing, regulation, supervision and audit of such multiple  dwelling.
The  agency  is hereby authorized to act as trustee or to consent to the
appointment of a banking institution or any subsidiary thereof to act in
such capacity and to provide such services as are generally performed by
any such bank itself  or  its  subsidiary  owning  and  holding  such  a
mortgage.
  7.  Banking  organizations  and  insurance companies may exercise such
power only to the extent and on such conditions as may be authorized  by
the state superintendent of financial services.
  8. Notwithstanding the provisions of any other law, a savings bank may
invest  to an amount not exceeding ninety per centum of the value of any
real property when jointly participating or investing in a loan pursuant
to the provisions of this  article  or  not  exceeding  ninety-five  per
centum  of  the value of any real property when jointly participating or
investing in a loan pursuant to the provisions of  article  fourteen  of
this chapter.
