There were a lot of perks to the card so I came out a head and built my credit score up to a respectable level in 4 months I believe.  

But as Richard said, use caution since the DoD has been changing a lot with respect to our TDY pay and procedures in the recent years.

Class B/C properties in A/B areas respectively makes sense, or areas that are gentrifying and in the path of progress on there way to higher quality areas.  

I understand building in additional income, but I think you are doing a long term dis-service to yourself in that respect.  

I believe the possibility of finding deals and having a more respected credibility is broadened and enhanced by using the internet.

I find that providing a good product, with quick service when a maintenance request comes in and a sense of respect really goes far with these type of people. 20-30% cap rates with low stress are possible in these areas.

Nobody gets rich by trucking, but it's a respectable living that can support a family.

(again, many BP posters are investing in the midwest for 2% rent/purchase.)If your total expenses are $1023 per month (not counting the mortgage), then NOI is $1176 and that calculates (as you say) at 6.96% and 4.97% , respectively, for $203k and $284k purchases.

It is good to know that you respect your elders (ha).

Keep in mind that I have no personal experience in this domain, and I treat electrical and plumbing with great respect.
