The overall role of a treasurer is to maintain an overview of the Residents Association financial affairs, ensuring its viability and ensuring that proper financial records and procedures are maintained.
In the case of HPV it's very likely that we will not be collecting member fees so the role may well be limited to what a treasurer of an RA would normally be expected to do.
However, there will be an expectation that the treasurer would have a financial background and would have involvement in working with the HPV service charge.
