Why It Matters
You'll use a P&L to answer the most basic question in rental investing: is this property making money? It starts with gross rental income, subtracts vacancy losses and every operating expense — taxes, insurance, management fees, repairs, and reserves — and lands on Net Operating Income (NOI). That number is what lenders, appraisers, and buyers all care about. One important nuance: mortgage payments and depreciation don't appear on a standard P&L, so your NOI is higher than your actual cash flow after debt service.
At a Glance
- What it is: A periodic income and expense report for a rental property or portfolio
- Core output: Net Operating Income (NOI) — the property's profit before debt service
- Who uses it: Property owners, lenders, accountants, and potential buyers
- Mortgage payments excluded: P&I is tracked separately, below the NOI line
- Required for: Commercial loan applications typically request 2 years of P&Ls
NOI = Effective Gross Income − Total Operating Expenses
How It Works
Revenue side — from gross to effective. The P&L opens with gross rental income: what you'd collect if every unit were rented at full rate all year. From there, you subtract vacancy and credit losses — the income you didn't collect because of empty units or non-paying tenants. What's left is Effective Gross Income (EGI). Many properties also have other income sources like laundry, parking, or pet fees; those add into EGI before expenses. Your vacancy-rate directly determines how much you lose off the top.
Expense side — what counts as operating. Operating expenses are everything it costs to run the property, excluding the mortgage. The big ones: property taxes, insurance, and property management fees (typically 8–12% of gross rents for professional management). Add repairs and maintenance, any landlord-paid utilities, landscaping, accounting, advertising, and capital reserves — the monthly set-aside for future big-ticket repairs like roofs and HVAC. Total those up, subtract from EGI, and you have NOI. That figure is the core input for cap rate analysis and what a lender's underwriting revolves around.
Basis matters — cash vs. accrual. Individual investors almost always use cash-basis accounting: income is recorded when it hits your account, expenses when you write the check. It's simple and matches your bank statement. Larger operators and entities required to follow GAAP use accrual-basis, which records income when it's earned and expenses when they're incurred, regardless of when cash moves. The difference rarely matters for a single-family rental but becomes significant for larger portfolios where timing mismatches between billing and payment can distort a given month's results. The income statement under accrual produces a more accurate picture of performance across periods. Your operating budget is the forward-looking version of the same structure.
Real-World Example
Lisa owns a single-family rental in Columbus generating $1,875/month — $22,500/year gross. Vacancy runs about 6%, so she loses $1,350 to empty periods, leaving an EGI of $21,150. Her annual operating expenses: $3,200 property taxes, $1,100 insurance, $1,800 property management (8% of gross rents), $1,400 repairs, $350 landscaping, and $1,125 reserves (5% of gross). Total operating expenses: $8,975. NOI = $21,150 − $8,975 = $12,175. On her $196,000 purchase price, that's a 6.2% cap rate — healthy for the Columbus market. Her mortgage P&I is $10,440/year; that number doesn't appear on the P&L but comes out of NOI when calculating cash flow: $12,175 − $10,440 = $1,735, or about $145/month after debt service.
Pros & Cons
- Forces a complete, structured picture of income and expenses — no more relying on gut feel
- Enables direct comparison across properties or time periods with consistent formatting
- Provides the NOI figure used in cap rate and DSCR calculations lenders require
- Supports tax prep by organizing the same data that flows onto Schedule E
- Reveals cost creep — expenses that quietly grow without a matching rent increase
- Cash-basis statements can make a property look better (or worse) than it actually is if timing of payments is uneven
- Doesn't capture capital expenditures as they occur — those hit when paid, not when the asset deteriorates
- Easy to omit reserves if you're not paying a property manager who sets them for you
- A single P&L period can be misleading; lenders and buyers want at least two years of data
- Mortgage principal paydown, which builds equity, doesn't appear — so P&L alone understates total return
Watch Out
- Depreciation isn't here — Schedule E is different. Your annual cash flow statement and tax return (Schedule E) both look like income-and-expense reports, but they're not the same. Schedule E includes depreciation — a non-cash expense that can turn a cash-positive property into a tax loss. It also deducts mortgage interest but not principal. If you hand your CPA a P&L and expect it to match your Schedule E, you'll be confused.
- Reserves are optional on a P&L — that's a problem. Many investors run their P&L without a capital reserve line. The property looks more profitable on paper, but one roof replacement blows up the math. Use 5–10% of gross rents as a reserve allocation to reflect true economics.
- Lenders want consistency, not creativity. Commercial lenders cross-check P&L income against rent rolls and bank statements. If your P&L reports rent income that doesn't match deposits, expect questions. Stick to cash-basis and let the numbers tell a clean story.
- Management fee basis confusion. Some PMs charge on gross rent, others on collected rent. A $2,350/month unit at 10% management costs $235 on gross — but if it's vacant two months, you pay nothing. Make sure your P&L reflects what you actually pay, not a theoretical percentage.

The Takeaway
A P&L is the foundational document for understanding whether your rental property is actually earning money. Run one monthly, review quarterly, and keep two years of clean records — not because your accountant asks, but because lenders, buyers, and your own deal analysis all depend on the income statement being accurate. Pair it with your operating budget to catch variance early and keep operating expenses from quietly eating your NOI.
