On pages 267 to 271 the same trial balance is shown as was analyzed in Chapters XXV and XXVI. To the figures there shown have been added the total debit and total credit appearing in each account during the last preceding month. These totals are quickly obtained if the form of general ledger shown in Form 7 (Section 17) is used. The accounts are grouped as follows:
D. Real Estate
An examination of each group of accounts shown in the statement on pages 267 to 271, will show that it contains all entries relating to that class, and the totals give the total of such transactions. The grand total of the summary agrees with the total of the trial balance given on pages 222 to 225. In practice, the bookkeeper usually has a number of blank forms typed in manifold, each one of these manifolded forms containing all the accounts in one classification. When this is done the time required to take off the monthly statement is not appreciably greater than that required for the regular trial balance.
It is often said by managers of real estate concerns interested in time sales, that it is impossible to show the amount actually earned in any one year, especially if that year be an early one in the history of the concern while the expenses and development are still increasing and when few sales have been completed. With monthly statements such as are outlined above, and with proper treatment of profits from time sales, it is possible to approximate very closely not only the earnings of a year, but the earnings of each month.
