For an office handling many rental houses, it is usually convenient to keep all matters pertaining to rents out of the general cash book. An ordinary cash book may be used for this purpose. All rents received, taken direct from the rent collectors' reports, are entered on the debit side, while on the other side are entered all payments made on account of such houses for repairs, insurance, etc.

Where such a book is kept, it is well to deposit all receipts from rent as shown therein, in a separate bank account, and to charge against this account all moneys paid out for repairs, etc., using for this purpose a check differing from that used in connection with the general cash account. At the end of each month the balance of this account is transferred to the general fund. This method eliminates from the general cash book a vast amount of detail which is shown to better advantage by itself.
