Offer to take the property on at cost, not with profit. Then employ companies and builders directly on fixed price contracts to build homes for subsidized rent and build a lot of houses of the type needed in places where they are needed. Stop this rash of highly-proitable "executive housing", the large numbers of crappy flats for "buy-to-let".
build homes for people, for indidviduals and families on low incomes. keep to the Fen Causeway
The key IMHO is to keep the land in public ownership, or take it into public ownership.
Builder/developers may be brought in as partners. They would invest an agreed profit margin, and any costs would be met by investors of risk capital, possibly from a constantly recycling pool of development credits.
Once a project is finished, long term investment in "Unitised" rentals would refinance the development credits, and allow the developers to realise any profits from their share of "Units".
The result is essentially a "Not for Profit" (but also "Not for Loss" ...! ) Real Estate Investment Trust.
Such partnership-based financing wipes the floor with conventional funding because:
(a) such "Community Equity" (within a partnership framework as opposed to the conventional "Equity" in a Company that makes the Private Sector "Private") involves no debt repayment: if investors want to release their Capital, they find buyers for their Units;
(b) "unitised" rents are;
(i) "affordable" - so more certain to be paid, and hence lower risk;
(ii) index-linked - so a lower return may be paid than when the return is non index-linked and eroded by inflation.
