Rental Property Analysis
Overview
Calculate key rental property metrics: net operating income (NOI), cash-on-cash return, cap rate, and ROI per property. Tracks rental income against property-specific expenses for Schedule E tax preparation.
Wilson Tools Used
transaction_search — find all income and expenses related to a specific property by vendor, description, or tag
spending_summary — aggregate property expenses by category (mortgage, insurance, repairs, management fees)
export_transactions — export property-specific transactions for tax filing (Schedule E)
Workflow
- Ask for the property (address or name), purchase price, down payment, and current market value. If multiple properties, repeat for each.
- Use
transaction_search to find all rental income for the property (tenant payments, security deposits).
- Use
transaction_search to find all property expenses (mortgage, insurance, property tax, HOA, repairs, management fees, utilities paid by owner).
- Use
spending_summary to aggregate expenses by category for the property.
- Calculate key metrics:
RENTAL PROPERTY ANALYSIS — [Property Name]
══════════════════════════════════════════════════════
Property: 123 Main St, Unit A
Purchase Price: $250,000 Down Payment: $50,000
Current Value: $275,000 Loan Balance: $192,000
ANNUAL INCOME & EXPENSES — [Year]
──────────────────────────────────────────────────────
Gross Rental Income $24,000
Vacancy Loss (est. 5%) ($1,200)
Effective Gross Income $22,800
Operating Expenses
Property Tax ($3,000)
Insurance ($1,200)
Property Management (10%) ($2,400)
Repairs & Maintenance ($1,800)
HOA Fees ($2,400)
Total Operating Expenses ($10,800)
NET OPERATING INCOME (NOI) $12,000
Mortgage Payment (P&I) ($11,520)
CASH FLOW (after debt service) $480
KEY METRICS
Cap Rate = NOI / Purchase Price = 4.8%
Cash-on-Cash ROI = Cash Flow / Down Pmt = 1.0%
Total ROI = (Cash Flow + Equity +
Appreciation) / Down = 18.2%
Expense Ratio = OpEx / Gross Income = 45.0%
1% Rule Check = Rent / Price = 0.8%
══════════════════════════════════════════════════════
- For total ROI, include:
- Annual cash flow: $480
- Equity buildup from mortgage principal paydown (check amortization schedule)
- Appreciation: (Current Value - Purchase Price) / Years Owned, annualized
- Total ROI = (Cash Flow + Annual Equity Gain + Annual Appreciation) / Total Cash Invested * 100
- Use
export_transactions for property-specific transactions to prepare Schedule E.
Without Wilson
- Export bank transactions from the account used for the rental property.
- In a spreadsheet, filter to only property-related transactions. Tag each with the property name if you own multiple.
- Sum rental income (positive deposits from tenants).
- Sum operating expenses by category. Common Schedule E categories: advertising, auto/travel, cleaning/maintenance, commissions, insurance, legal/professional, management fees, mortgage interest, repairs, supplies, taxes, utilities.
- NOI = Gross Rent - Vacancy Allowance - Operating Expenses.
- Cap Rate =
=NOI/PurchasePrice*100.
- Cash-on-Cash =
=(NOI - AnnualMortgagePayments)/DownPayment*100.
- For the mortgage principal paydown, check your loan amortization schedule (available from your lender's portal or use bankrate.com/calculators/mortgages/amortization-calculator).
- For Schedule E filing: IRS Form Schedule E lines map to specific expense categories. Use TurboTax Rental Properties or FreeTaxUSA for guided entry. Depreciation is calculated as Purchase Price (minus land value) / 27.5 years for residential.
Important Notes
- Cap rate does not include mortgage payments — it measures the property's return independent of financing. Use it to compare properties.
- Cash-on-cash ROI includes financing and measures return on your actual cash invested. It can be negative if mortgage payments exceed NOI.
- The 1% rule (monthly rent should be >= 1% of purchase price) is a quick screening heuristic, not a hard rule. Many profitable properties do not meet it, especially in high-cost markets.
- Depreciation is a non-cash expense that reduces taxable income but not actual cash flow. Residential rental property depreciates over 27.5 years. This is a significant tax benefit not reflected in the cash flow numbers above.
- Track capital improvements separately from repairs. Repairs are expensed immediately; improvements (new roof, HVAC) are depreciated over their useful life.
