Have to have a Real Estate license to do one of these deals and B.

I am in c to b- areas.

a) Use the rental property I already acquired as the physical address of the LLC (seems like it would be difficult to reliably collect mail there after it is rented)b) Contract a private company, such as UPS, to provide a physical address in West Virginia for the LLC.

If the power company really did take that long, it would have been up to the PM to a.) inform you, and b.) put into action a mitigation plan

If the home is in a good neighborhood  (A/B), I would hold and take the positive cash flow over time, as the home *should* appreciate in value. 

@Jason Ma, @Ariou B., got it exactly right in his example. 

What do you think is the best area in VA to begin investing in B, B- , & C class neighborhoods?

His mother is going into an assisted living facility and needs to sell...all they are looking for is to pay off the mortgage owed (about $108K) I would prefer not to come out of pocket to satisfy in full b/c i have other projects going on and i'm a bit cash strapped until they close.

Since I'm not a US resident alien I won't fill 1040NR but 8888-B so it will take three months to get refunded from the withheld amount.  

You want to focus on quality, long-term tenants, so B/B+ areas are going to be your bread and butter.
