How To Get Last Payment And Amt Of All

This will get me what I need based on an entered client id, but what is I want it to return the last payment date and amt for all loans? I tried removing the two where clauses and it only returned the last payment entered but not for all loans.SELECT dbo.tblLoan.Client_ID, MAX(dbo.tblPayments.PaymentDate) AS [Last Pay Date], SUM(dbo.tblPayments.AmountPaid) AS [Last Pay Amt]
FROM dbo.tblLoan INNER JOIN
dbo.tblPayments ON dbo.tblLoan.Loan_ID = dbo.tblPayments.Loan_ID

WHERE (dbo.tblLoan.Client_ID = @Client_ID)
AND dbo.tblPayments.PaymentDate =
(
SELECT TOP 1 p.PaymentDate
FROM dbo.tblPayments p
INNER JOIN dbo.tblLoan l
ON l.Loan_ID = p.Loan_ID
WHERE l.Client_ID = @Client_ID
ORDER BY p.PaymentDate DESC
)

GROUP BY dbo.tblLoan.Client_ID
