Series LLC: Real-Life Solution?

I’ve been reading about Series LLCs. We own several apartment buildings and this sounds like a perfect solution in terms of trimming accounting costs, filing fees, banking costs way down while keeping the asset protection features of LLCs. Problem is my buildings are in NY and NY doesn’t have Series LLCs yet. If I use a Deleware Series for instance, what will be the real-world impact in terms of cutting down accounting costs and perhaps most importantly the ability to limit creditors to charging orders and non-piercing of corporate veil? Thanks.

Series LLCs only work in states that authorize them. A state like NY will treat it just like any other NY LLC.
