“Dear PoPville,

I’m dealing with some landlord issues and thought this could be a good crowdsourcing question:

In general, how much do DC renters/readers think that features add a premium to rental. In other words, two apartments being otherwise equal, what would be the rental difference between the two if one of the units had the following features:

Central air and heat (as opposed to window units and radiators)
Ceiling Fans (as opposed to exposed-bulb fixtures)
Garbage disposal
Dishwasher
updated bathroom with vanity (as opposed to old bathroom with no vanity, just sink hanging on the wall)
security system”
