What was effective in those programs in the 1970s and 1980s, which were supported by multiple governments, goes back to the significant level of investment. That's not just a one, two or three-year program, but a multi-year program so that you can really plan ahead. Those programs featured financing and capital contributions in the form of either grants or operating subsidies.
The other feature that was quite exceptional about these legacy programs was that they also offered rental assistance to low-income households. There were actual rental assistance subsidies available to make housing co-operatives and non-profits even more inclusive and to meet the housing needs of low-income and more vulnerable households.
