The Complete Rental Property Expense Checklist
2026-02-20
Underestimating expenses is the #1 mistake new rental property investors make. Here's every cost you should factor into your analysis.
Fixed Monthly Expenses
- Mortgage (P&I) — Principal and interest on your loan
- Property taxes — Check county records, not the listing
- Insurance — Landlord policy, not homeowner's. Budget $1,200-2,400/year
- HOA fees — If applicable. Can range from $50-$500+/month
Variable Expenses (% of Gross Rent)
- Vacancy — 5-8% in strong markets, 8-12% in weaker ones
- Property management — 8-10% if hiring a manager, 0% if self-managing
- Maintenance — 5-10% for ongoing repairs
- CapEx reserves — 5-10% for major replacements (roof, HVAC, appliances)
Often-Forgotten Costs
- Lawn care / snow removal — $50-200/month depending on location
- Pest control — $30-50/month
- Accounting / bookkeeping — $100-300/month
- Legal fees — Budget $500-1,000/year for lease reviews, evictions
- Advertising / turnover — Cost to re-list and prepare unit between tenants
The 50% Rule (Quick Check)
A common rule of thumb: total operating expenses (excluding mortgage) will average about 50% of gross rent over time. If your detailed analysis shows expenses at 30%, you're probably missing something.
