Can anyone have a house plot or they have set a limit?

I was wondering if I need to act fast and stack up some cash for a house because I don't know if the game have set a limit on the server for housing. Like did they set a limit of 100 000 houses all around the world in-game or everyone could have a house plot and don't have to worry for a space left.

I remember playing Ultima Online and the world went full and no place was left to place a house plot, we had to find someone who was selling it. Good old time.
