If the reason that you are trying to move the ownership of the properties to their own LLC's is to protect yourself from liability if your tenant sues you, it may be too late. I think you want to talk to a lawyer rather than a CPA about this. I've been told that if you get sued and you claim that the property is owned by the LLC and thus they can't try to get your other properties or your personal property, their lawyer will investigate your finances. If the lawyer ever finds any co-mingling of funds between your personal accounts and the rental property, they will claim that the LLC was not completely independent of the other LLC's or your personal property and that all of that property is fair game for them to go for in their lawsuit. I'm told it's very hard to keep all of the finances separate.
If you did, good for you and you may be able to separate the properties out into separate LLC's, but then you also have the issue of ownership of the properties. If you have mortgages on the properties, you are unlikely to get the bank to change the ownership to the LLC without writing a new mortgage. You may have to pay off your 3% mortgage and need to get a 7% mortgage in its place.
