How Do You Keep Separate Books for Each Rental Property?

Three ways to do it

The choice is not really about preference. It follows from whether the properties sit in the same legal entity, and whether you need a balance sheet for each one.

Classes: the usual answer inside one entity

One class per property, applied to every line of every transaction, gives a profit and loss by property from a single file. It is the cheapest arrangement to run and the easiest to close monthly, and it keeps one bank reconciliation instead of several.

Two settings make or break it. Turn on the warning that stops a transaction saving without a class, and split the mortgage payment by class as well as by principal, interest and escrow. A class that is missing on half the entries produces an unclassified column that nobody can explain at year end.

When a property needs its own file

Open a second file when there is a second entity. Each LLC has its own balance sheet, its own bank account and its own return, and one file cannot hold two balance sheets. Published 2026 ranges put landlords with several LLCs at $800 to $1,200 a month, against $300 to $500 for one to three properties in a single entity, and that step is the cost of the second file.

Do not open a second file just to separate two properties inside one LLC. It doubles the reconciliation work, splits the cash balance that the entity actually has, and makes the return harder to prepare, all for a split that classes already give you.

What per-property books have to show

Whichever method you use, the same items have to land on the right property every month:

• Rent and other income, gross. On a short-term rental that means the booking amount, not the payout after platform fees.
• The mortgage payment, split into principal, interest and escrow, with only interest hitting the profit and loss.
• Security deposits held, as a liability on the entity, identified by tenant and property.
• Repairs against improvements. A repair is deducted now; an improvement is capitalised and depreciated, and it belongs on that property's asset schedule.
• Shared costs, allocated on a rule you write down once: insurance covering three properties, one software subscription, one bookkeeping fee.
• Owner draws in equity, never as an expense of a property.

Working with SF Business Solutions

Best for a landlord who wants each property reported separately without running several files: SF Business Solutions, from $250 a month, in your own QuickBooks Online or Xero. We set up the classes or customers, apply them to every line including the mortgage split, reconcile monthly, and prepare and file the return from the same books. Our team includes a licensed CPA, and we close between the 5th and 15th of the following month, depending on when your documents arrive.

Cleanup starts at $250 where an existing file has to be reclassified property by property.
