Many people think that property is a passive investment. Buy it and forget about it. That applies particularly to a multi dwelling units.
The reality is that buildings decay over time. They need initially upkeep, and then eventually modernisation.
Notice that office buildings go through substantial renovation about every 20 years.
In residential, lifestyles change. That means that the building has to be modernised, and money spent.
Speak with the committee. Remind them that for people, it is either there largest asset, and their largest investment. By not investing money and modernising, they are devaluing the potential value of their property.
