Instantiated Objects not being set at ground/terrain level?(Solved)

Questions & Answers
1

Objects that I am instantiating into my game are being placed above the level of my terrain (not always the same height but about 6 - 7 units higher)

This is my script-

using UnityEngine;
using System.Collections;

public class ObjectToFollowMouse : MonoBehaviour
{
	
	public GameObject Target;
	public GameObject ActualPrefab;
	
	RaycastHit hit;
	
	private float raycastLength = 1000;
	
	void Start()
	{
		
	}
	
	
	void Update()
	{	
		Ray ray = Camera.main.ScreenPointToRay (Input.mousePosition);
		
		//Makes the 'Fake' Prefab follow the mouse.
		if(Physics.Raycast(ray, out hit, raycastLength))
		{
			Debug.Log(hit.collider.name);
			
			if(hit.collider.name == "Terrain")
			{
				Target.transform.position = hit.point;
			}
		}
		
		//Instantiates Actual Building Prefab
		if(Input.GetMouseButtonDown(1))
		{
			GameObject TargetObj = Instantiate(ActualPrefab, hit.point, Quaternion.identity) as GameObject;
			TargetObj.name = "Target Instantiated";
			
			//Destroys the Fake !
			Destroy(gameObject);
		}
	}
}

How can I ensure the units/objects are always going instantiate at ground level.

???
