Saving a Masonic Temple

I was elected last night as a member of the Board of Trustees responsible for the Masonic Temple in Portland. We are in a similar situation to many Grand Lodges with old Masonic buildings in the city core: high expenses (heat, electricity, parking, etc), plenty of internal and external maintenance to be done, and restricted income (primarily rent). I would love to hear suggestions for how other such groups have recovered from a similar situation? I would hate to see the work of great men like Augustus Schlotterbeck lost as office space or condos. What we have in Portland is a real turn of the century jewel and it is our task to ensure this jewel is available for future generations of Freemasons.
