Security Deposit Ledger

Security deposits are the single most disputed part of renting. Tenants sue over them more than any other issue, and landlords lose most often for two boring, preventable reasons: missing the state's refund deadline, and failing to send an itemized statement. Both are paperwork problems, not legal ones — which is exactly why a simple ledger beats memory and spreadsheets. Paid property-management platforms gate deposit tracking behind monthly subscriptions; the free alternatives are static spreadsheet templates with no deadline awareness at all.

The deadline is the trap. In Arizona and New York you have just 14 days from move-out; in California 21; in most states 30; in Pennsylvania 60. Miss it, and in many states the tenant can recover double or triple the deposit regardless of how legitimate your deductions were. This ledger computes the due date the moment you enter a move-out date, and the badge on each tenant card shifts from green to amber to red as the deadline approaches — so a busy week never costs you a deposit's worth of penalties.

The second half of protection is itemization. When you withhold any part of a deposit, most states require a written list of every deduction with its amount, delivered by the deadline. Vague entries like "cleaning — $200" invite challenges; specific ones like "professional carpet cleaning, living room pet stains — invoice #1042, $200" survive them. Log each deduction with its category, a plain-English description, and the amount as soon as the cost is known, and the printable refund statement assembles itself.

A few habits make the ledger airtight. Photograph the unit at move-in and move-out and pair this ledger with a written inspection — deductions without before-and-after evidence are hard to defend. Keep receipts for every repair and cleaning cost; note the receipt or invoice number in the deduction's notes field. Send the refund statement even when the refund is zero — several states penalize landlords who simply keep the deposit silently. And when deductions exceed the deposit, the ledger flags the shortfall so you can decide whether to bill the former tenant rather than discovering it at tax time.

• Enter the move-out date the day it happens — every deadline counts from that date.
• Normal wear and tear is not deductible in any state: faded paint, minor scuffs, worn carpet paths.
• Export the ledger monthly; browser data can be cleared by accident.
