Portfolio Asset Allocation

[YoungAndNotFree]

Hello everyone,
I have started to invest US$500 monthly, and will have 3 times a year that I receive bonuses to make lump sums.

Basically I have at this time 70 shares of VTI and this month bought 5 shares of VNQ. My question is from a practical perspective, what should I buy every month? VTI? And rebalance with VNQ (I’m trying to have 10% in VNQ for volatility/income) instead of BND.

Rebalance yearly or just on a monthly basis?

Edit: I’m 30, and a really long time horizon.

And also any feedback as of this asset allocation.

It's not a real big deal, since you are making regular monthly purchases just buy whatever it takes to stay close to your chosen AA. Even easier if your broker has $0 commissions.

Thank you Rob! Yes it is 0 comission.
