LLC'ing existing properties

[Joseph Duff]

Hey People - 

My wife and I own 3 single family homes (including our primary home) they are all in our names, and we are in the process of selling 1 of them in Scottsdale and use the profits to invest in a new property on the east coast.  

The question is, we would like to start an LLC for our properties, but we don't know if we could consolidate the other properties into the LLC when we form it without too much additional costs.

Is it possible?  Is there any way to consolidate multiple properties under the same financial product?

Thanks in advance.  :)
