As noted elsewhere, M. and I checked out a house for rent near Rockville (close to Whiteflint Mall and Strathmore.) Rent will be comparable to what we have now. It is dramatically closer to Z.'s school and her mom's house, though. The living space isn't that much larger than our current apartment, and the layout is different, but there's more storage space. And my commute should be slightly better. More details as things take shape. So! Here's hoping.
