Too early to get started?

[Brook Boatman]

I am pleased to meet you all and look forward to starting on this journey.  

I am a married 23 year old on active duty military with my contract expiring in two years.  I live in Southern Pennsylvania near the Maryland border and only a short drive from DC.  I want to start making moves but am hesitant due to uncertainty of where I will be living post-military.  Should I start now, should I wait to buy?

I have no debt, savings around 20,000 and growing.  My main interest is buying a multifamily and occupying it. 

All and all, any advice about getting started specific to my situation would be appreciated!
