8406 Hartford Avenue Silver Spring, MD

One of the houses that I have been following has been sitting on the market. The prices keep on dropping:

The house was originally listed for 679K; then reduced to 649K, then 629K, and now 599K. See my blog post about 8406 Hartford Avenue.

The price has been reduced once more to 579K. That is 4 reductions totally 100K or 14%. Why? The housing bubble is popping in the DC area. Also, just down the street is 8300 Hartford Avenue. ( MLS MC5402312 ) which is available for 579K ( it had been reduced from 599K. Which one sells first? and for what price?
