From multiple discussions I've had and reading posts here, I think I also want to form a 5th LLC to act as a management company, so that I can have one business account and credit card to collect all rent and pay all the overhead and expenses (paying for meals, PO box, RE licensing fees, etc).  

You still have to know the pro forma rents though since literally nothing meets the 1% rule based on in place rents.

You can change your ID form as many times as you want before the 45 day deadline.  

I would use those figures when you run your pro forma i dont think many lenders are going to buy off on a 2 to 3 month start to finish.. just sayin.

As you suggested, one option is to form a new LLC with the original name while keeping the old LLC intact.

Plus, as you know our markets aren’t known for yearly rent increases so it’s cute to see when folks run pro-forma’s with such estimates.

As far as I know in ny state you have to actually form a new entity to file as an Scorpio?

I was hoping folks has suggestions because I kept running into dead ends because the physical bank location of the online bank platforms need to be in the state to follow the rules for MA. 

As someone who recently had to form a foreign LLC for an out of state property that I own, I definitely wouldn't do it unless I absolutely have to.

If one or both intend to live in the duplex, yes, by all means, put an agreement together.You form a California LLC with your sister and friend as managing members and then quitclaim the property into the LLC.
