I know little about housing prices in DC other than that it is fairly expensive. Based on what I know I pay and my understanding of prices, $2400 won't get you much once you factor in taxes. I imagine you will want to live in a nice suburban area with at least 4 BR/2BA, 2000 sf, $2400/month in an amortizing payment is a $400k mortgage (without factoring in taxes, if taxes are ~$6000/year, that reduces the mortgage to $325k). I don't think you can get much with a mortgage like that in the DC area. Having said that, a $2400/month subsidy is mighty nice.
