How Do You Catch Up Rental Books That Are Years Behind?

What it costs to catch up

Published 2026 benchmarks price bookkeeping cleanup at $150 to $600 for each month you are behind, and the rental end of that range depends on property count, entity count and whether any property is a short-term rental with pooled payouts to unpick. Two years across four doors is 24 months of work, not two.

Cleanup with SF Business Solutions starts at $250. The final price depends on how far behind the books are, how many entities there are, and whether the properties have ever been reported separately.

Rebuild in this order

Order matters more than speed. Doing it out of order means redoing it, because every year depends on the one before it:

• Gather the documents for every open year: bank and card statements, mortgage year-end statements, closing statements from any purchase or sale, platform earnings reports, lease agreements and deposit records.
• Fix the chart of accounts first, with one class per property, so entries do not have to be reclassified later.
• Enter and reconcile the oldest year month by month, to the bank statement, not to a plug.
• Split every mortgage payment into principal, interest and escrow using the lender's year-end statement.
• Rebuild the fixed asset and depreciation schedule from closing statements and improvement invoices, property by property, then carry it forward through each later year.
• Set security deposits held as a liability, and clear any that were returned or applied to rent.
• Close each year, then start the next one from its closing balances.

What trips a rental catch-up up

The same five things slow almost every rental rebuild:

• Mortgage payments recorded as one expense, which overstates deductions in every year they appear.
• A missing depreciation schedule. Without it there is no basis to carry forward, and the closing statement from the purchase is the only place the numbers exist.
• Personal and rental money in one account, so every transaction has to be sorted by hand.
• Short-term rental payouts recorded as net deposits, which have to be split back into gross revenue, platform fees, cleaning fees and occupancy tax.
• Repairs and improvements mixed together, so deductions and asset balances are both wrong.

Then the open returns

Catching up the books is half the job. Published 2026 preparation fees run $200 to $500 for a simple Schedule E, $800 to $1,500 for a complex one, $1,000 to $2,500 for a Form 1065 and $1,200 to $2,500 for a Form 1120-S, and each open year needs its own return.

SF Business Solutions prepares and files those returns from the books we rebuild, so the same team carries the numbers through. We keep the records and prepare the returns; we do not represent taxpayers before the IRS, and we do not rule on whether a property qualifies for a particular tax status.

Working with SF Business Solutions

Best for a landlord who is two or more years behind and wants the rebuild and the filings handled together: SF Business Solutions, with cleanup from $250 and monthly bookkeeping from $250 a month afterwards.

Once the backlog is closed, we keep you current and close each month between the 5th and 15th of the following month, depending on when your documents arrive.
