I agree that MVC's waiver doesn't seem to put reserves into dire financial straits. But in the event of a big unexpected expense or several unexpected expenses occurring in quick succession, the likelihood that a special assessment would be necessary is greater if full reserves have been waived.
I'd rather put what the law requires into reserves, even if it makes my MF's rise by $50 or $100, and know that the property can cover itself in 98% of possible scenarios. I'm admittedly conservative on such issues. I also think it's most fair that current owners pay the true costs of their ownership, and those costs include paying fully into reserves for the very real depreciation of the properties which occurs little by little every day.
If the elevators need replacing five years earlier than planned because of corrosion due to salt air, the people who should have paid that expense are the owners over the past 15 years (or however long it's been since the last replacement), not the folks who happen to own when the bill comes due. Full funding of reserves is the best system we have for making it work that way.
