Glad to help if you are still in the search process!
I respectfully disagree with the notion of looking for housing on Craig's List. Craig's list is best for people looking to rent one room in a shared property. The "two out of three" homes figure is incorrect. Only 20 percent of all housing in the Washington, DC metro area is leased or sold "by owner". Beware of scams on Craig's list and do not send money to anyone who asks for it up front. Do not give anyone money on Craig's list until you have checked the tax record and verified they have the legal right to Lease the property and that the property is fully available.
I specialize in relocations and would be happy to help you!
A good way to check out the homes listed with a real estate agent is our team's Web site, http://www.betterhomesva.com. This ties into our regional multiple listing service.
