A friend of mine is selling three appartments he has. He is not a broker or agent. Two are in Yerevan Physics Institute district and one in Davidashen. I've quickly put together a page with details: http://www.circle.am/apps4sale/
If you insist they will say the price, but they really want to go other way. You tell your price - and they see if they can go with it. If not, they will tell the closest amount that they can accept.
