Brokers Riding Similar Listings. Any strategies as a buyer?

I have seen this happen twice now and as a buyer it's frustrating (although I can why the sellers like it). Here's the situation: there are two units of the same line in the same building (identical floor plans), and one is clearly better than the other. For example: 10B - renovated kitchen and bathroom, drops listing from $630K to $585K 6B - needs renovation, was listed at $599K The 10B unit is... [more]

I have seen this happen twice now and as a buyer it's frustrating (although I can why the sellers like it). Here's the situation: there are two units of the same line in the same building (identical floor plans), and one is clearly better than the other. For example: 10B - renovated kitchen and bathroom, drops listing from $630K to $585K 6B - needs renovation, was listed at $599K The 10B unit is clearly worth more, since it's renovated and on a higher floor. Once it drops its price to $585, 6B realizes it too need to lower its price, and drops to $580. 10B then accepts an offer for $550K (I know this, but the market as a whole does not), and its status on all the websites changes to "In Contract $585K". So in my mind, 6B is CLEARLY worth less than $550K since this apartment is inferior. Yet, the broker tries to ride the wave of 10B's "in contract" status on the $585K ask price. So, to buyers who have never seen 10B, she can effectively try to get above $550. Any thoughts on strategies as a buyer, wanting to buy 6B, but only for under $550 since I know what 10B went for?
