Oof. Yea if they are looking to go north to avoid commute, White Sands wouldn't be an option in my book.
Plenty of cheaper options in Deale/Shady Side/Rosehaven/North Beach/Ches. Beach. Huntingtown, Owings, Sunderland, Dunkirk, etc. are other options as well without passing through the afternoon Prince Frederick traffic.
Not sure what their price range is, but the more north you go, the more expensive it is (generally speaking, $1,000 extra per mile north).
Keep in mind, if they are using a USDA RHD loan, the USDA exempts White Sands and CRE as options for that loan. Maybe the Beaches as well, not sure.
