What Should a Landlord Review in Their Books Every Month?

What goes on the monthly checklist?

Run it in this order, because each step assumes the one before it held. Reconciliation comes first; nothing after it means anything until the books tie to the statements.

1. Every account reconciled to its statement. Bank, credit card, and mortgage, each tied to the closing balance on its statement. This catches missing transactions, duplicates, and bank feed gaps before they compound.
2. Uncategorized items at zero. Nothing left in an uncategorized bucket, and nothing parked in a holding category to sort out later. This catches the transactions that would otherwise sit outside every report until someone finds them in January.
3. Rent received equals rent expected, per unit. Every gap has a name: vacancy, late, partial, or a deposit that landed in the wrong month. This catches a tenant who quietly short-paid and a rent deposit tagged to the wrong door.
4. Security deposits still sitting as a liability. The Security Deposits Held balance equals the deposits you are actually holding, and matches the deposit bank account if you keep one. This catches a deposit booked as rent and a refund that never cleared the liability. The setup is in security deposit accounting.
5. Mortgage payments split, and the loan balance matching the lender. Principal, interest, and escrow each went where they belong, and the loan balance on the balance sheet equals the balance on the servicer’s statement. This catches a payment booked as one expense line, which overstates costs and freezes the loan balance. The mechanics are in how to split a mortgage payment.
6. Anything large in repairs checked against the capital improvement test. Pick a threshold, say $1,000, and look at every repair above it. This catches a water heater or a roof sitting in repairs instead of on the balance sheet, which is the error that is hardest to rebuild once the invoices are gone.
7. Owner draws and contributions tagged as equity. Money you put in is a contribution and money you took out is a distribution; neither is income or expense. This catches a personal transfer that inflated revenue and a draw that showed up as a cost of running the property.
8. Per-property P&L glanced at for a number that looks wrong. One door’s insurance doubled, another shows no rent, a third has repairs on a unit that had no work done. This catches mis-tagged transactions that every prior step would pass. Getting a P&L per property covers the tagging that makes this step possible.

What can wait for a quarterly look?

Three items move slowly enough that a monthly check is wasted effort. Once a quarter is the right cadence.

• 1099 vendor totals. Run payments by vendor for the year to date and confirm a W-9 is on file for every unincorporated contractor you have paid. Whether a form is required is your CPA’s call; having the total and the W-9 ready in January is yours.
• Escrow account against the escrow statement. The servicer’s escrow statement shows deposits in, property tax and insurance paid out, and the ending balance. Tie your escrow asset to it, and confirm the bills the servicer paid were recorded as the actual expense in the month they were paid, not before.
• Capital improvement schedule. List every improvement added this year with the property, a description, the total cost, and the date it went into service, and confirm each one sits on the balance sheet at cost. This is the list your CPA depreciates from, and what your CPA needs at year end shows where it lands in the package.

“Year end is boring when every month was closed properly. The monthly review is what makes it boring.”

How long should the review take?

About twenty minutes, once the close itself is done. The close is the work: importing, categorizing, tagging, reconciling. The review is a pass over the results, and it is quick because every item is a comparison between two numbers that should agree. Either they match or they do not, and when they do not, you know which month to open.

If the review is taking an hour, the problem is usually upstream of it. A step that fails three months running is a setup problem, such as a mortgage split that was never saved as a recurring template, and fixing the setup is cheaper than fixing the same entry twelve times.

The habit compounds. A landlord who runs this list every month arrives at year end with a balance sheet that ties to every statement, an improvement schedule already built, and nothing uncategorized. The CPA package becomes a matter of running reports. A landlord who skips it arrives with the same errors, twelve months deep.

The Bottom Line

Monthly: reconcile every account, clear uncategorized to zero, tie rent to the rent roll, confirm deposits are a liability, check the mortgage split and the loan balance, test large repairs against the improvement rule, tag draws and contributions as equity, and glance at the per-property P&L. Quarterly: vendor totals, the escrow account, and the improvement schedule. The same list is on one page in our free monthly close checklist.

Frequently asked questions

Do I still need a monthly review if my software reconciles automatically?

Yes. A bank feed matches the transactions it recognizes. It does not tell you whether the closing balance ties to the statement, whether one unit’s rent came in short, or whether a large repair should be an improvement on the balance sheet. Software handles the matching. The review handles the judgment, and the judgment errors are the ones that surface at year end.

What if I am months behind and have never done a monthly review?

Catch up first, then start the habit at the current month. Reconcile each missed month in order, because a wrong closing balance in March becomes a wrong opening balance in April. Once the books are current, the review takes about twenty minutes and stays there. If the backlog is more than a few months, a one-time cleanup is usually faster than working through it alongside the current month.

Should I compare the loan balance every month or only at year end?

Monthly. The check takes under a minute, and the fix gets more expensive every month it waits. The servicer’s statement shows the balance after each payment; if the balance sheet does not match it, a split is wrong somewhere. Finding one bad month in June is far easier than rebuilding twelve of them the following March with only the Form 1098 to work from.
