Also, I’m not sure where you are in your career but you need to be able to focus and serve your unit/commander well, especially on deployment.

The thought process is to buy a new condo or a town home, furnish with a high-end package, go with an established marketing / booking agency - and command higher rents.

You won't have the turnover, and your property will maintain its value, and you will be able to command a premium in rent!   

Tell them if they have a problem with this you'd be happy to put a call into his or her Company Commander. 

Since they have concentrated their purchases into pockets of major cities, it means it will be hard to command top dollar if you are selling 10 homes on the same block.

command line AWK and SED scripts that are less cumbersome than SQL JOIN queries that I can never seem to get right;) 

You can typically gain more value by duplexing the 1st unit down with the basement commanding more rent.

Does it make economic sense to buy a house with private sewerage with the expectation that it will command a high value if changed to the city sewerage? 

If Mr Arsenault were to buy one of the many run-down student rentals in 'the 'nish' and simply paint, renovate the kitch & bath he could likely command a premium :)  It's actually quite a fun and vibrant town for its size!

Problem is, a new house would never command a sale price equal to the cost to build it in those areas!!!
