You will be fine. Don't stress. I WISH I still lived in York County where my American dollar was equal. Here, I don't have the option of finding reasonably priced produce. I pay $3.50 for a head of lettuce as of last week in the commissary. I go off base and while the price seems cheaper, add 50% for the currency conversion.

I was just in York County 2 weeks ago visiting family and I walked into a Farm Fresh supermarket and bought a head of lettuce for 88 cents. Wal-Mart was about the same price. Bananas here are $1.11 a pound. They were 3 pounds for a buck in America. It is nothing for us to buy a weeks worth of groceries and it costs us almost $300! I almost faint and wonder if the cashier made a mistake when I shop at Wal-Mart and it comes to half that much. WIth that amound saved, even if housing were unaffordable in Hampton Roads, the money I would save in groceries and not to mention gas, it would be affordable to me.
You can get a nice apt or even house (nothing elaborate like a $500,000 one mind you) for about $1,300-$1,600 a month. It really depends on the neighborhood. They all are nice as far as I am concerned. We did alot of searching through EVERY neighborhood with a map when we were thinking of buying a house in York County before moving here. We will probably be moving back there when we are done here.....or maybe we will end up in DC. Not sure.
There are limited apts in this area. Here is the list. Stay away from Pines of York and Four Seasons (going down hill). We stayed at Belmont at York 4 years ago. Not sure how it is now (it was really nice when we were there), but at least this will give you an idea of the expense of living here. We did find a few houses back then that were around $1,400-$1,600 a month. A few years ago, my parents lived in a duplex in a very nice neighborhood that was I think $1,200 a month. I would suggest contacting the local real estate agents for a rental house. That is how you will find most of them. I found having pets to be the greatest obstacle.
The York County YMCA is VERY nice. We also like the library next door....very tranquil. They are located on Magruder. Our favorite weekend thing was visiting the AMC 24 theater. It is about a 10 minute drive away. Fantastic stadium style seating. Sure beats the 1970's style one level seating we have on base here. You will have many military bases close by. Of course, Langley AFB, Ft Lee is in Hampton and Ft Eustis is on the far end of Newport News. Norfolk has the Naval base (and a really nice exchange and biggest commissary). My only complaint about Langley was the pharmacy. They tried so hard to stop people from using the pharmacy and utilize either a civilian pharmacy or that new mail order pharmacy that they made it nearly impossible to get a prescription on base. Walk in and take a number. Wait at least 30 minutes and show your ID. Go sit back down and wait for your name to be called. This could take up to another 1-1/2 hours.

I don't know how it is now, but 4 years ago they really had people hating that place.
Just relax. The move will be fine. You will like living there. Lots for a family to do. Don't forget the zoo in Norfolk and the Living Museum in Newport News. Across from that is the SPCA which has a small petting zoo for a small fee. I think the Childrens Museum is either in Norfolk or Va Beach. We did not do too much traveling on that side of the water except for hubby to go to work on the base. We were pretty busy people as we are now.
Good luck!
