The people appointed in municipalities to monitor should do monitoring at least weekly, that is physicaally and the books.

Municipalities should also do away with the tendering system.
Appoint people to oversee the building of the houses with proper qualifications and hire unemployed local people to build houses as this is what the people who win the tenders do. The problem is that they cannot run the business and are too hasty for self gain.
The municipality buys the material from the wholesalers in a strictly monitored systemmmm and allocate to a stock controller.

Municipalities should also ensure that there are no people who are not on the lists that get the houses and that the houses are not sold to others, including illegal foreigners
