Month-End Close for an Apartment Building: The 15-Step Checklist We Run
A month-end close is the set of steps that turns an apartment building's bank statements, rent roll and loan statement into a finished set of monthly reports that will not change afterward.
This is the close Multifamily Bookkeeping runs, in order, with the report each step produces. The checklist further down prints on 1 page, with a tick box and a blank for the date beside each step. The sample building, Birch Way with 50 units in October 2026, is invented data.
What is a month-end close for an apartment building?
A month-end close is the set of steps that turns an apartment building's bank statements, rent roll and loan statement into a finished set of monthly reports that will not change afterward.
The order is fixed: collect, record, prove, review, send. Each step has one action and one output, and the output of the last step is the report package. A month is closed when the reports are sent and the month is locked, so the report the owner read stays the same when it is read again later.
The close ends when it produces the monthly report package for an apartment building: the cash view, the rent roll, unpaid rent, the P&L, budget against actual and the balance sheet.
What do you need before closing an apartment building's month?
3 records: the bank statement for every account, the month's rent roll, and the loan statement with its escrow and reserve balances. A manager's owner statement is added where there is one.
- The bank statement for every account the building has: operating, deposits and reserves. All 3, for the full month.
- The month's rent roll: every unit, its tenant, its rent, what was due and what was paid. Where a manager runs the building, the owner statement comes with it.
- The loan statement for the month, showing the payment, how the lender split it, and the escrow and lender-held reserve balances.
With these 3 in hand the close runs without a question. Missing 1 of them, it stops at the step that needs it.
What are the 15 steps of an apartment building month-end close?
Collect 3 sets of records. Record 7 kinds of entry, from the bank lines to the loan split. Reconcile 3 accounts. Then review the reports and send the package.
Here are the 15 steps in their 4 groups. Each row has the step, one sentence on why it is there, and the report it produces. The Birch Way figures sit beside the step that produces them.

Collect (steps 1 to 3)
| ☐ | Step | What is done | What it produces | Date done |
|---|---|---|---|---|
| ☐ | 1 | Collect the bank statement for every account: operating, deposits, reserves. Every later step is checked against these 3 statements, so nothing starts until all 3 are on file. | Statements on file | |
| ☐ | 2 | Collect the month's rent roll and, where a manager runs the building, the owner statement. The rent roll says what every unit owed; without it the bank deposits are just money. | The rent roll | |
| ☐ | 3 | Collect the loan statement, with the escrow and lender-held reserve balances. The lender's statement is the only record of the money the lender holds for you. | Loan statement on file |
Record (steps 4 to 10)
| ☐ | Step | What is done | What it produces | Date done |
|---|---|---|---|---|
| ☐ | 4 | Record every deposit and payment on the bank statements, tagged to the building. A line left off the bank statement is a report that cannot tie, so every line goes in first. | A complete transaction list | |
| ☐ | 5 | Record rent due from the rent roll: rent if full, vacancy, concessions. Rent is recorded as what was due, so the P&L shows what the building could earn and what it gave up. Birch Way: rent if full $72,500, vacancy $4,350, rent $68,150. | The income lines of the P&L | |
| ☐ | 6 | Match the rent roll to the bank and name each line of the gap. Rent due and rent banked differ every month, and each dollar of the difference needs a reason. How the gap is named line by line is in rent roll vs bank statement. | Rent roll against the bank | |
| ☐ | 7 | Update the unpaid rent list by unit and by age. The owner needs to know who to call, and a list by age shows which units are new and which are months behind. | The unpaid rent list | |
| ☐ | 8 | Record bills received and not yet paid. A bill in the drawer is money already spent, and the cash view counts it. | The bills due list | |
| ☐ | 9 | Split the loan payment into interest, principal, escrow and reserve deposit. One draft leaves the bank and 4 different things happen in the books. Birch Way: a $41,050 draft is the $33,500 loan payment ($24,300 interest and $9,200 principal), $6,500 of tax and insurance escrow and $1,050 of replacement reserve deposit. How the payment is split is in recording a multifamily loan payment. | A loan balance that matches the lender | |
| ☐ | 10 | Record the month's share of property tax and insurance. Both are paid once or twice a year, and a P&L that shows them in 1 month and not the next cannot be read. Birch Way: property tax $4,600 and insurance $1,900 for the month. | Even cost lines on the P&L |
Prove (steps 11 to 13)
| ☐ | Step | What is done | What it produces | Date done |
|---|---|---|---|---|
| ☐ | 11 | Reconcile the operating account. The cash line on every report rests on this balance. What each account must equal is in bank reconciliation for an apartment building. | Reconciliation report | |
| ☐ | 12 | Reconcile the deposit account and tie it to the deposit ledger, unit by unit. The account holds the tenants' money, so the bank balance must equal the sum of the units. Birch Way: 47 deposits at $750, $35,250. How the ledger is kept is in security deposit accounting for apartment buildings. | The deposit ledger | |
| ☐ | 13 | Reconcile the reserve account, and tie escrow and lender-held reserves to the lender's statement. Reserves in the building's bank are proved by the bank statement; reserves and escrow at the lender are proved by the lender's statement. | The reserve schedule |
Review and send (steps 14 and 15)
| ☐ | Step | What is done | What it produces | Date done |
|---|---|---|---|---|
| ☐ | 14 | Read the P&L against last month and against the budget, and question every line that moved. A number that moved has a reason, and the owner should get the reason with the report. Birch Way: net operating income $41,150, left after the loan $7,650. | P&L, budget against actual, balance sheet | |
| ☐ | 15 | Build the cash view, lock the month and send the package. Locking stops a later entry from changing a month the owner has already read. Birch Way: $112,000 in the bank, $41,000 owed back or set aside, $78,000 of bills due, real cash -$7,000. | The cash view and the 6-report package |
Steps 1 to 3 are the only ones that wait on someone else. Steps 4 to 15 are the bookkeeper's, in this order, every month.
How is an apartment building's close different from a company's close?
An apartment close has 3 steps a company close lacks. The rent roll is matched to the bank. Every tenant deposit is tied to its unit. Money the lender holds is tied to the lender's statement.
- The rent roll is matched to the bank (step 6). A company records the sales it made; a building also records the rent it was owed and did not get, line by line.
- Every tenant deposit is tied to its unit (step 12). The $35,250 in the deposit account belongs to 47 tenants, and the close proves the account equals the list.
- Money the lender holds is tied to the lender's statement (steps 9 and 13). Escrow and lender-held reserves never pass through the building's bank, so only the lender's statement can prove them.
Everything else, the bank lines, the bills, the reconciliations, the review, is the same close any business runs.
When is an apartment building's month really closed?
When 4 things are true: every account is reconciled, the deposit ledger equals the deposit account, each line of the rent gap has a name, and the month is locked against changes.
- Every bank account is reconciled: operating, deposits and reserves, each to its own statement, with a saved report.
- The deposit ledger equals the deposit account: at Birch Way, 47 units at $750 and $35,250 in the bank.
- Each line of the rent gap has a name: a vacant unit, a late payer, a special, a timing difference.
- The month is locked against changes, so the package the owner read is the package that stays.
A bank feed with every line put in a category passes none of the 4 tests. It is where step 4 begins.
Who does what in an apartment building's month-end close?
The owner or the manager sends the statements and the rent roll. The bookkeeper runs the 15 steps. The owner reads the package and answers the open questions.
| Who | What they do | Which steps |
|---|---|---|
| The owner, or the manager who runs the building | Sends the bank statements, the rent roll, the owner statement where there is one, and the loan statement | Steps 1 to 3 |
| The bookkeeper | Records, reconciles, reviews, locks the month and sends the package | Steps 4 to 15 |
| The owner | Reads the package and answers the open questions: a line that moved, a unit behind on rent, a bill to approve | After step 15 |
The owner's part is reading. At year end the 12 locked months go to your CPA as one file, and the year-end work is theirs.
