What would you do? where to invest

[Account Closed]

I've been debating with myself on where to invest my money. I presently have a duplex which was purchased on '06 as a primary residence/rental. I purchased this for $325,000 and presently owe aprox $280,000 at 6.5% it is on an ARM and should reset this December. Work brought me to a town where I purchased a REO property for $140,000 last December and owe aprox $106,000. I also have aprox $40,000 saved up to go in on another deal with a partner. I'm presently adding an additional $600 to the monthly on the duplex and $250 to the single family home. So my question is would you continue to do the same strategy or would you put the money towards one of the presently owned homes. Would you continue the early payment of both homes or pool the money towards one of them?
Thanks in advance
