[Flame On]

Hey all. Here's some background.
I'm currently selling a condo. It was listed before christmas when there was a bit of a lull in the market, as well as the natural Christmas lull.
It was priced very reasonably almost under priced to allow for a quicker sale. However that didn't happen.
Now there are several more units of the same floor plan in my development that have come online. One is 4 grand more, one 7, one is 10 and one is asking 14 grand more in asking price.
Also, we've just got our property tax assement through and it's much higher than our assessed listed price.
All of this leads us to wonder if we've left money on the table. To say nothing of the fact that we can't really take less than asking price now, and how many people will want to buy without getting anything off at all?
Finally, now we're getting closer to when we really do need to sell by, mid February for our new place.
So the question is.
Do we relist slightly higher, is that even possible?
Or do keep the price and use the lower price to our advantage?
(by the way we do have an agent but she's on holiday and of course they're always more inclined to reduce the price and certainly not raise it.)
If you've read all this and have advice, bless you!
