This should work:

pawn Код:

public OnPlayerSpawn(playerid)
{
    SetTimerEx("CheckArea", 1000, true, "i", playerid);
    return 1;
}
    
forward CheckArea(playerid);
public CheckArea(playerid)
{
    if(IsPlayerInArea(playerid,2424,-1758,2640,-1620))
    {
        SendClientMessage(playerid,COLOR_GREEN,"Your on Property of GS Watch Your back");
    }
    else
    {
       SendClientMessage(playerid, COLOR_RED,"You're not on Property of GS.");
    }
    return 1;
}

stock IsPlayerInArea(playerid, Float:minx, Float:maxx, Float:miny, Float:maxy)
{
    new Float:x, Float:y, Float:z;
    GetPlayerPos(playerid, x, y, z);
    if(minx < x < maxx && miny < y < maxy) return true;
    return false;
}

NOTE: This WILL spam the player with messages once they spawn, it would be better to assign it to a command rather than a timer.
