I'd like the first two to apply to apartments, any rent-able property really.

After that is the development stick. Tax property at a minimum based on the surrounding average property tax rates. This will encourage proportional investment in areas and prevent hold-outs who are waiting for some hypothetical from sitting on a community asset forever.

What if for some reason the property is really worth less than the surrounding properties? Seems like a recipe to have properties that barely pay for themselves, which discourages investing in renovations, etc.
