Most players will not sell houses (considering how hard they work to get them.) Most houses go for (I believe) somewhere around one hundred and fifty thousand true, if they're available. Housing creates a significant drain on the server, so it's deliberately kept scarce. You might be able to rent a room.. I believe that the Leilon Arms periodically has openings. The usual rate is about three thousand true/RL month.
Regardless, I think a whole house may be a bit ambitious as yet... but there may be some available on Central or East, should you be determined to become a homeowner.
