<human>: Location: Virginia in the DC suburbs.  I'll try to keep this short.

I'm currently renting a 1 bedroom place for $1559/month from an apartment tower built in the early 1960s.  My lease expires January 5.  At renewal, they quoted me for $1559/month again (first year with no rent increase since I've been there).  I was curious, so I went on their website and saw two identical units (same floorplan as mine) for $1299/month and $1359/month.  I asked the apartment complex to see if they could lower my rate, and they countered with $1499/month. It's better than their first offer, and better than I was expecting going into the renewal, but still $200/month more than the identical units on similar floors (I'm on the 5th floor, with the two identical units on the 4th and 6th floors). 

Do I have any legal leverage here based on the advertised price online, or can they pretty much offer whatever they want?  I know I have some leverage in the standard sense because they know they're charging me more than the market rate.  Accordingly, I have some flexibility to negotiate, but from a legal standpoint, are they obliged to honor the lower rates shown online? Am I allowed to non-renew my lease then simply sign a lease with one of the other units for the lower price?  Would they have to honor the price if I followed that strategy, or could they deny me because I'm a previous tenant?  If they have to honor that rate for me to move into one of the other units, it seems like it would be easier for both parties to avoid the hassle of moving one floor up or down and just stay in my current unit on the 5th floor.  That's my ideal outcome.

Provide a brief overview of the text.
<bot>: I want to stay in the same building, but I don't want to pay so much more than market rate.  Do I have any legal standing to get the advertised rate?
