We were interested in rolling money from a sale of a triplex into a larger property.

If your landlord wants more rooms painted, I would tell him to hire a contractor and I pay 3200.You can roll two rooms in an afternoon and in the end it's only $100 and at least you have someone who seems somewhat flexible.

They said that per California Revenue and Taxation code, they're asking me to provide them info such as the purchase agreement, rent rolls, etc. to assist them in doing the reappraisal of my property.  

It sounds like you've got the ball rolling in the right direction already, so keep up the great work!

The assignment fees then enabled me to roll into other strategies, buy and hold, fix and flip.  

Do you have a rent roll for at least the last 2 years, so you can see how it has performing?

Is there an energy company (electrical and Gas) that will do roll overs?

Marie Johnson - please see this link where what you proposed in your post seemed to occur for somebody:http://www.patheos.com/blogs/slacktivist/2012/11/13/rolling-jubilee-proclaim-liberty-throughout-all-the-land/

It's pretty rare I see any that is super easy and the cash just keeps rolling in. 

One client came in hot looking for a multi-unit in Phoenix - they wanted to roll over gains, keep taxes deferred, and jump into a hotter market.
