Select Object and move on Right click Position - Error!

Heres my script but I get an error:

 using UnityEngine;
 using System.Collections;
 
 public class MouseActivity : MonoBehaviour 
 {
     RaycastHit hit;
     GameObject SelectedObject;
 
     void Start () 
     {
     
     }
 
     void Update () 
     {
         MouseInput();
     }
     
     private void MouseInput() 
     {
         if(Input.GetMouseButtonDown(0)) LeftMouseClick();
         else if(Input.GetMouseButtonDown(1)) RightMouseClick();
     }
     
     private void LeftMouseClick()
     {
         Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
         if(Physics.Raycast (ray.origin, ray.direction, out hit, 100))
         {
             //print (hit.collider.gameObject);
             if(hit.collider.name == "Terrain")
             {
                 print ("");
             }
             else if(hit.collider.tag == "Building")
             {
                 SelectedObject = hit.collider.gameObject;
                 SelectObject();
             }
         }
     }
     
     private void RightMouseClick()
     {
         Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
         if(Physics.Raycast (ray.origin, ray.direction, out hit, 100))
         {
             if(hit.collider.name == "Terrain")
             {
                 if(SelectedObject != null)
                 {
                     SelectedObject.transform.position(hit.point);
                     
                 }
             }
         }
     }
     
     private void SelectObject()
     {
         print (hit.collider.name);    
     }
     
 }

The error says "Non-invocable member, Transform.position can't be used as a method" on this line: SelectedObject.transform.position(hit.point);

This is C#, any ideas how to resolve this?
