bethesda/ chevy chase is the second most expensive place to live in MD behind potomac, the houses are astronomical and apt.s are dumb expensive. It is very pretty and a bunch of things to do, dc is like 10 mins away and the metro is easily accessible. if your one for diversity bethesda has none, mainly rich white folk. but there are a ton of tasty restaurants....
bmore is really cheap houses in the city run like 200k and 3 bedroom apts are less than one bedrooms in bethesda or dc. The city is filty though, with the exception of the few blocks around the inner harbor. if your looking for diversity in race, there is alot. If your looking for diversity in Socioeconomic status, there is none most bmore city inhabitants are poor or working class. a past thread poster said there is less traffic in bmore; thats not true, there is just as much. and whats worst is the public trans there is diguesting so your only option is to walk or talk the car. also crime is rampant where as in bethesda the only crooks are the lawyers and brokers pushing jags, and bentleys...
advice to you try silver spring if your looking for apartment living, its close to bethesda near a metro station, minutes from dc, lots of young people and families and its in the middle of regentrification, so if your looking at realestate you can still get in before prices go sky high.
one person suggested gaithersburg but the prices are already so high out there and the traffic leaving and getting there is ridiculous even on sundays.
i hope this helps good luck!
