Problem to rename gameobject when loading from file.

I use this code to read a text file and fill my map. Everything work except the House.name.

Only the last instantiate object have the right name.

 using (StreamReader sr = File.OpenText(path)) {
                     string s = "";
                     while ((s = sr.ReadLine()) != null) {
                         overLoadtxt = s;
                         string[] splitArray = overLoadtxt.Split (' ');
                         loadStr1 = splitArray [0]; 
                         loadStr2 = splitArray [1]; 
                         loadStr3 = splitArray [2]; 
                         loadStr4 = splitArray [3]; 
                         loadStr5 = splitArray [4]; 
                         loadStr6 = splitArray [5]; 

                 
                         if (loadStr2 == "House") {
                             Instantiate (House);
                             if (loadStr6 == "LuxHouse") {
                                 House.GetComponent<SpriteRenderer> ().sprite = img1;
                             }
                             if (loadStr6 == "House1") {
                                 House.GetComponent<SpriteRenderer> ().sprite = img2;
                             }
                             if (loadStr6 == "Greentex") {
                                 House.GetComponent<SpriteRenderer> ().sprite = img3;
                             }
                             House.tag = "House";
                             House.transform.localScale = new Vector3 (0.5f, 0.5f, 0);
                             House.transform.eulerAngles = new Vector3 (0, 0, float.Parse (loadStr5));
                             House.transform.position = new Vector3 (float.Parse (loadStr3), float.Parse (loadStr4), 0);
                             GlobalManager.intHouseName ++;
                             House.name = loadStr1;
                         }

When i use the Debug.Log on loadStr1, everything show up right. House1, House2...

The .name seem to not work with loop. How can i populate the map with the saved name in my .txt file.

Thx for your help, i'm clueless with this strange mechanic.
