have very little chance to get a response to this on these boards. Better to try the Tristan boards on VN forums.
And usually, on most servers, if patient, you can find a lot for cheaper than someone would sell it to you anyway. With exception of the very big servers such as Gareth, Lancelot and Merlin, open lots are available always.
I just checked Dalton on Tristan, and there are about 20 lots available. I would bet that one of those is already down to 300 gold. And if not, I can't see how one of the 20+ lots would not make it to that price. If Dalton has 20+ lots open, I would imagine there are more than 100 lots to choose across entire housing directory.
Did you check camelot herald's housing directory? know how to use it? I found this stuff out in under 3 minutes of time looking for it. Try it out. It is helpful.
