Property management bookkeeping done right.

Property management is a legally sensitive business in every state. State real property statutes and real estate commissions set strict rules on how landlord and PM company money can be handled — and violating them can cost you your license, your properties, or both. Yet most small landlords and boutique property managers we onboard are running their books like it is a regular small business. It is not.

Here is what real property management bookkeeping looks like, whether you own 5 units or manage 500 units for other people.

Security deposits are trust money. Full stop.

In nearly every state, security deposits are the tenant's money, held in trust by the landlord. They are not the landlord's revenue. They are not available to spend on other things. They live in a specific type of account, and the exact rules vary by state.

Common state-level requirements landlords need to follow (specifics vary; check your state):

• Security deposits typically must be held in a separate account (often required to be interest-bearing) with a financial institution licensed in-state
• Many states require interest to be paid to the tenant at a statutory or market-linked rate (Maryland uses 1.5 percent simple; other states vary or waive the requirement)
• Return timelines after move-out are strictly regulated (14 to 60 days depending on state), with itemized deductions if any are made
• Failure to comply can result in the tenant recovering multiple times the wrongfully withheld amount plus attorney fees in many jurisdictions

From a bookkeeping standpoint, this means every security deposit should:

1. Live in a designated liability account on the balance sheet (not revenue)
2. Be tracked per tenant with move-in and move-out dates
3. Have interest accrued monthly or quarterly at the applicable rate (if required in your state)
4. Reconcile to the actual balance in the trust account

If your books show security deposits as revenue, or if they are commingled with operating cash, this is the first thing we fix on a property management onboarding.

Rent escrow: the trap most owners have never seen.

Most states allow tenants to withhold rent and pay it into a court escrow account if serious habitability issues go unresolved. Maryland's Residential Landlord-Tenant Act (MRLTA), California's Civil Code § 1942, and similar statutes in most other states all provide this mechanism. When rent gets paid into escrow, the money is not yours to spend even though it is technically owed. It sits in an escrow account controlled by the court until the issues are resolved.

For bookkeeping, this means:

• Rent paid into escrow shows up as receivables, not revenue, until released by the court
• The tenant's ledger should reflect payments made into escrow the same as payments made directly to the landlord (they are legally equivalent for calculating whether the tenant is current)
• You need documented tracking of the case number, escrow amount, and resolution status

Most cities also layer their own rental license and habitability requirements on top of state law. Baltimore City requires a rental license from the Department of Housing & Community Development. Chicago has its own rental license and RLTO obligations. Los Angeles has RSO. New York has its own regulatory framework. Whatever city you operate in, the local license fee, inspection cost, and any citations should be tracked as property-level operating expenses.

Per-property NOI, not just portfolio NOI.

The single most valuable report for a property owner is a per-property P&L. Which properties are actually making money, which are dragging, and which are one bad tenant away from a problem.

To get this, your chart of accounts and QuickBooks class tracking need to be set up right from day one:

• Each property is a QuickBooks Class (or in some setups, a Location)
• Every rent payment is coded to a property class
• Every expense (repairs, utilities, insurance, property tax, mortgage interest) is coded to a property class
• Portfolio-wide overhead (office rent, admin salaries, software) is coded to a general admin class and allocated by unit count or by revenue

Once this is running for 90 days, you can generate a monthly per-property P&L that shows NOI by unit. You will see immediately which properties are pulling weight and which are quietly bleeding cash. Most owners we onboard have never seen this view for their own portfolio.

Local rules that always need tracking.

Rental licenses. Most cities require an annual rental license per property, with an inspection. Track each one as a property-level operating expense with the license number in the memo field so you can pull it up when a tenant or inspector asks.

Lead paint compliance. Pre-1978 rentals across the country are subject to federal disclosure rules (EPA), plus state and local layers (Maryland, Massachusetts, and others have particularly strict requirements). Registration fees, testing, and remediation should be tracked at the property level as capital or operating expenses depending on scope.

Utility billing. Some jurisdictions bill water, sewer, or trash to the property owner directly; others bill the tenant. Where the owner is billed and the lease passes it through, that flows through your books as a receivable (from tenant) and payable (to utility) simultaneously. Missing this creates a slow-moving receivables mess.

Property tax. Real property tax rates and billing cycles are set by county or municipality and vary widely. Whatever your jurisdiction, real property tax is deductible when paid. Do not forget to reconcile the tax bill against what your mortgage escrow paid on your behalf if you have escrowed loans.

NOI vs. cash flow — a companion problem.

We wrote a full post on why NOI and cash flow are different numbers for landlords. It applies to every rental portfolio, where mortgage principal + capex + trust deposits + utility float can leave you cash-poor even on a profitable portfolio. Every PM should build the NOI-to-cash bridge monthly.

What we do for property management clients.

We run this whole stack for landlords and PM companies nationwide. Per-property books, trust account reconciliation, security deposit tracking that stays inside your state's rules, and clean monthly reporting. Our co-founder Ravi built and still runs a boutique property management company (Sungate Property Management), so this is not theoretical — we live inside the workflow.
