This sentence means that once we decide to go scout for a site - i.e. when we consider that The Reef is a viable project and we are confident we can make it work - that we go back to the current system, in which the 2000 euro is a non-refundable contribution to The Reef’s bank account.
The proposal of splitting up the 2000 euro into a 500 euro donation + a loan of 1500 euro, is a security mechanism. Should it happen that the economic conditions worsen even further and we consider that it’s not a good time to build a cohousing, then the 500 euro stays in the bank account (as per asbl legal requirements), but The Reef neatly pays back all of the 1500 euro loans it received, so that Full Members lose less money. So the trick is to convert part of the 2000 euro into a loan, so that it is legally possible to pay it back.
The reasoning behind the 500 + 1500 is that this still requires a significant financial token of commitment (wire transfer of 2000 euro), but it’s a bit safer because one can recover 1500 euro should The Reef fail. At the same time it is aligned with our budgetary requirements: we sort of need the 500 euro per household to pay for our current costs (if we apply the current system we are in a deficit), and we’ll need the 1500 euro to pay the architects once we start scouting (for the feasibility studies).
