Also, the city is considering an ordinance that would require the landlord (or property manager) to prepare tenants' possessions for bedbug treatment.  

Why are we even talking about the tax treatment of Mello Roos on a primary residence?

Some CPA firms will run a cost/benefit analysis as to whether an S-corp is a beneficial tax treatment for your flipping business. 

My personal practice is to ignore such requests and I apply it consistently just like tenant screening - so if you have sent me one and think I'm a jerk for not reciprocating, now you know why ;-)There have been several threads covering the topic of Colleague Request etiquette in the past: Will Bernard, Jason Munck, (the never opinionated) Hattie Dizmond, and Pyrrha Rivers have each raised the subject and given it a far more thoughtful and thorough treatment than you could hope to hear from me at this time.However, I do have a couple of suggestions for @Joshua Dorkin and his ever growing crew at BP central:{one might be seen as a little draconian}: Make it a requirement to include a message (Note of Introduction) when sending a colleague request; and/orhave one of the BP support team crawl through the above threads (and the others to which I did not link) on Colleague Request and Private Message etiquette and add a FAQ/Sticky thread to the New Member Introductions forum.

Whether the courts of a non-series LLC state would respect the liability shields of a series LLC is not known.The IRS has issued proposed regulations providing insight into the IRS’ treatment of these entities:1) Each series within a series LLC will be treated as a separate entity for federal income tax purposes;2) Each series is allowed to choose its own entity classification independent of the classification of other series; and3) Each series should only be liable for federal income taxes related to that series.The proposed regulations do not address the entity status of a series organization for federal tax purposes nor do the proposed regulations specifically address whether each series within a series LLC should obtain a separate employer identification number (EIN) and file a separate federal tax return.Until final regulations are issued, I advise clients to obtain separate EINs and file separate income tax returns for each separate series which, I believe, helps each series maintain separate and distinct corporate identities, thereby reducing the risk anyone may be able attached a judgment to you or another series and pierce the corporate veil.Other ways to minimize the chance that one series may be held liable for liabilities of the entity as a whole (or another series) include the following:1) Create a separate bank account for each series (again, you’ll need a separate EIN to do this)2) Don’t commingle funds within series.3) Always sign documents in the name of the series.4) Properly document all loans between series.5) Conduct all transactions between series in an arms'-length manner at fair market prices using appraisals.6) Keep the assets and operations of each series separate from the other series.

My official Facebook opinion is that it’s just a matter of which blow actually knocks this ordinance out - fellow council members who realize this whole this is lunacy...voters who continue to put pressure on city council directly reminding them that they were voted in and can be just as easily voted out...or the lawsuit itself calling to light the abuse of authority between city council and the county health dept and the unequal treatment of rentals only regulating <4 units (city council members just happen to own large rental properties).
