Lets help you get things in order
Is buying a home on your current assignment wise?
What is the current status of the market in the area you are looking?
Have you gotten pre-qualified?
What are your basic housing needs? (i.e. Beds, Baths, Fenced Yard, etc. etc.)
What are your wants? (things you would like/love but also things you could live without if necessary)
How far would you like to be from post?
Location, location, location...... how far from school, groceries or any other important places you might need access to.
All of these things are items to simply consider when you are getting started with what is likely going to be one of the biggest decisions of your life. The main thing is don't just settle for any house, make sure you get the feeling like it's home.
