You can have as little as one timer a time for a player when they go to that building, and then destroy it after 5 seconds. In other words, you can have very few:

pawn Код:

//top of script
new Timer; //The variable so we can destroy the timer later
forward StopBuildingText(playerid);

//Under PlayertoPoint Function check
ShowBuildingTextForPlayer(playeird); //Your callback for showing the text
Timer = SetTimerEx("StopBuildingText", 5000, 0, "i", playerid);

public StopBuildingText(playerid)
{
  //Your script for destroying the textdraw
}

Something similar to this.
