Perhaps something like this...
select id, create_date, loanid, rate, pays, gracetime, emailtosend, first_name, last_name, user_id
from (
      select distinct a.id,
                      create_date,
                      a.loanid,
                      a.rate,
                      a.pays,
                      a.gracetime,
                      a.emailtosend,
                      d.first_name,
                      d.last_name,
                      a.user_id,
                      max(create_date) over (partition by a.user_id, a.loadid) as max_create_date
      from CLAL_LOANCALC_DET a,
           loan_Calculator b,
           bv_user_profile c,
           bv_mr_user_profile d
      where b.loanid = a.loanid
      and   c.NET_USER_NO = a.resp_id
      and   d.user_id = c.user_id
      and   a.is_partner is null
      and   a.create_date between
            TO_DATE('6/3/2008 01:00:00', 'DD/MM/YY HH24:MI:SS') and
            TO_DATE('27/3/2008 23:59:00', 'DD/MM/YY HH24:MI:SS')
where create_date = max_create_date
order by create_date
