We're halfway through our semester of Curbed University so it's time for another Friday Open Thread. We're changing the routine a little from last time by asking for questions that we'll send to our expert and report back with her answers on Monday. Want to know whether or not it is the right time to buy? Curious whether you make enough to cover an average DC mortgage? Ask away in the comment section. Or send your question in to our tipline at email@example.com and we'll gather up all the questions in one place.
