Do you have a job lined up alreadY? Where will you work? Will both of you be working? What type of home are you looking for and what is your budget?
I lived in North Bethesda of Rockville (20852) and liked that everything was within a short driving distance and I was close to the Metro. There are numerous condos and townhouses in the area that range in price from the mid $300s to $800s. Single family homes are in the mid $600s and up.
Howard county is another nice place to live (Ellicott city/Columbia), especially if you have to commute to Baltimore.
I had realtors from Washington Fine Properties that were excellent. Realtors cannot tell you about schools; however.
Here is a link that I use when I search for schools and you can ask a realtor which communities feed into a particular school.
