As a real estate agent and military spouse, I know and understand the pressures of buying a home, as well as the stress of having to make that decision on a short timetable. My best advice is to:
1)Get pre-approved and know what your budget is and then stick to that budget
2)Find an agent you trust- usually the best agents are those your friends refer you to- I get most of my clients through word of mouth.
3)Make two lists- your "mandatory" list, and your "dream" list. What you absolutely can't live without in a home goes on your mandatory list, and you shouldn't look at houses that don't meet those minimum requirements. Your "dream" list should be all those things you'd love to have in a home if you can find it in your price range, but that you really could live without if you can't find them in a home that is otherwise suitable.
4)Select an area or location you'd like to be in, or a radius from a certain base or landmark, otherwise, it can be like looking for a needle in a haystack.
5)Try not to look at more than 3-5 houses at a time without taking a break, otherwise they will all blur together and you won't remember what you saw.
6)Finally-try to look past the current homeowners decor or taste- you aren't buying their artwork or furniture! Try to block out their things and picture your things in the home. Focus on the layout and features of the home rather than the colors and the decor.
