One property, one ledger.

Schedule E — the tax form for rental income — has one requirement that surprises new landlords: it's filed per property. One column for each. If your books lump three rentals into one pile of transactions, someone has to un-lump them in April. Set up right, the form fills itself in.

Track these categories, per property

Schedule E's expense lines are a ready-made chart of accounts. Mirror them in your books and year-end becomes a printout:

• Advertising & tenant screening
• Auto and travel (documented trips to the property)
• Cleaning and maintenance
• Insurance
• Legal and professional fees (including bookkeeping and tax prep)
• Management fees
• Mortgage interest (interest only — principal is not an expense)
• Repairs
• Supplies
• Property taxes
• Utilities you pay
• Depreciation (your CPA calculates it; your books make it possible)

The distinctions that matter

Repairs vs. improvements

A repair keeps the property in working order — fixing a leak, patching drywall — and is deductible this year. An improvement makes the property better or extends its life — a new roof, a renovated kitchen — and must be depreciated over years. Label big expenses clearly when they happen; the invoice wording ("replace" vs. "repair") genuinely helps your CPA.

Security deposits aren't income

A refundable deposit is a liability — you're holding the tenant's money. It only becomes income if you keep part of it. Booking deposits as rent inflates your income and your tax bill.

Mortgage payments are three things

Each payment is part interest (deductible), part principal (not an expense), and often part escrow for taxes and insurance (deductible when paid, and only once — not again when the escrow disburses). Books that expense the whole payment get all three wrong at once.

How to set it up

• Give every property its own tag. QuickBooks classes, Xero tracking categories, or even separate bank accounts — the tool matters less than the discipline that every transaction carries its property.
• Keep a folder per property for leases, closing statements, improvement invoices, and loan documents. The closing statement from the purchase is the foundation of your depreciation schedule — never lose it.
• Review a per-property P&L quarterly. It's not just for taxes: it's how you find the unit that quietly stopped earning its keep.
