Speak with your professional accountant as to what you can do to boost your 80% revenue stream from shareholders so that your 20% is not reached. There are strategies, but you need explore them with your professional. One that comes to mind is the use of master meter of electrical services with re-invoicing of services to shareholders and/or providing cable / internet services to residents and rebilling them, etc. Again, you are boosting your operating budget by the service being absorbed by the co-op, then billing shareholders for their use to incrase your 80% good revenue while reducing your 20% from bad income.

So, your best bet is a good discussion with the accountant and building some concrete strategies with your board.
