Put it outside the loop and return true at the end.

PHP код:

CMD:knock(playerid, params[])
{
     new bool:nearHouse = false;
     for(new idx; idx < MAX_HOUSES; idx++)
     {
         if(IsPlayerInRangeOfPoint(playerid, ...)
         {
             nearHouse = true;
             for(new i = 0, j = GetPlayerPoolSize(); i <= j; i++)
             {
                  //code;
             }
         }
         return 1;
      }
      if(nearHouse == 1)
      {
           SendClientMessage(playerid, COLOR_WHITE, "You are not near a house.");
       }
