Tax Question: Can investment loss be carried over?

We bought 3 rental properties last year as investment, and have much more expense than income for all of them. Turbo tax stopped loss amount at the 2nd house before the third house loss haven't entered in. Does anyone know if i can carry over the loss on the 3rd house to next year?

Also what's the definition of 2nd home? can it be rent out 8 out of 12 months? or once you rent it out, it's not 2nd home anymore, but investment property?

thanks!
