        {
            if(HouseInfo[h][hOwned])
            {
                format(string,sizeof(string), "~w~%s~n~~w~%s~n~~y~%d", HouseInfo[h][hOwner], GetLocationArea(HouseInfo[h][hEnterX],HouseInfo[h][hEnterY],HouseInfo[h][hEnterZ]), h);
            }
            else
            {
                format(string2,sizeof(string2), "~w~[House For Sale]~n~Price:~r~$%d~n~~w~%s~n~~y~%d", HouseInfo[h][hPrice], GetLocationArea(HouseInfo[h][hEnterX],HouseInfo[h][hEnterY],HouseInfo[h][hEnterZ]), h);
            }
            GameTextForPlayer(playerid, string, 5000, 5);
            GameTextForPlayer(playerid, string2, 5000, 5);
            return 1;
        }
    }
    return 1;
}
