Distractions and obligations are minimal and you can concentrate on your career.

I don't have any experience in vacation rentals myself, but I would imagine that vacancy and occupancy are, in most markets, concentrated to a few weeks/months like you saw on AirBnB.  

Most weddings are concentrated in the spring/summer, so you end up with a much smaller number of dates to actually work with.

The concentration of massive, unchecked power in a single Director marks a departure from settled historical practice and makes the CFPB unique among traditional independent agencies.”The Bureau was created in July 2011 out of the Dodd-Frank Act.

I would also recommend concentrating on newer homes for your first rental. 

It is driving me nuts because real estate is what I am thinking about and should be concentrating on finishing school, about 18 months more.

The concentration of sold SFR tend to by on the fringe of the metro where cheaper new housing is constructed where as the rental SFR tend to be nearer the urban core where prices are much higher.

I would find out if any of the low income areas are being revitalized and concentrate there.Frequent inspections are necessary.  

At first which is better  concentrating on building a buyers list or go straight for sellers?

I would say try to pay a fair amount on all, but concentrate on the smallest and get it paid off as soon as possible, then double up on the next lowest one.
