You don't need a return, break will break the loop. By the way, the message and LoadPlayerSpawnData must be inside the if statement about owned and the same owner.

if(PlayerInfo[playerid][pPlayerOwnsHouse] == 1)
{
    new playername[24];
    new string[64];
    GetPlayerName(playerid, playername, sizeof(playername));
    for(new idz = 1; idz < sizeof(HouseInfo); idz++)
    {
        if(HouseInfo[idz][hOwned] == 1 && strcmp(HouseInfo[idz][hOwner], playername) == 0)
        {
            SetPlayerPos(playerid, HouseInfo[idz][hEntranceX], HouseInfo[idz][hEntranceY], HouseInfo[idz][hEntranceZ]);
            TextDrawHideForPlayer(playerid,Textdraw0);
            TextDrawHideForPlayer(playerid,Textdraw1);
            SendClientMessage(playerid,COLOR_WHITE, string);
            format(string,sizeof(string), "Welcome back to your home, %s.", GetName(playerid));
            LoadPlayerSpawnData(playerid);
            break;
        }
    }
}

@PowerPC603: 2 separated if is the same thing. If the house is not owned, it will not check the strcmp match.
