I'm not sure how much interaction I'm supposed to have with the tenants (since I'm using property management), but I'm a very outgoing person, and would love to interact with the tenants.

It did for me.If you're just starting out, going into student housing can be a bit more challenging than regular rentals as you may have to deal with more issues that arise from them being there.

It would be a bonus if the service is free, and if my VA is able to make outgoing calls from that number.

Staying below that number of units will keep any mistakes you may make small enough to not destroy you.As Rich pointed out, going to larger quantity doors gets you into unchartered waters such as the laundry contarcts, etc.Managing a 12 unit or a 4 unit is identical.

I use skype everyday almost every day...I get incoming calls on my computer,Outgoing calls costs $29.99 a year right now i think.

There is a location where like minded investors gather in Lake forest every month that you should check out. Go

Have an open discussion and figure it out. Go

I used the worst numbers for outgoing costs and the worst numbers for incoming costs and came up with 236 cashflow per month. 

I wonder how it's outgoing with the designed house in Texas it is build?

I talked to a title company who I had a good relationship with and they were able to give me a list of pre-foreclosures or you could always go to the county websites and look up auction lists and go 2 months out (going to auction 2 months from now) and try to get a hold of them.
