Frequently Asked Questions
Property taxes typically represent 15-30% of total operating expenses for rental properties. In high-tax states like New Jersey, Illinois, or Texas, taxes can consume 2-3% of property value annually, significantly impacting cash flow. A $300,000 property with a 2.5% effective tax rate costs $7,500 per year in taxes, or $625 per month. This must be fully factored into your cash flow analysis.
Yes, property taxes on investment and rental properties are fully deductible as a business expense against rental income, with no cap. This differs from the $10,000 SALT (State and Local Tax) deduction limit that applies to primary residences. Property taxes reduce your taxable rental income and are deducted on Schedule E. This tax benefit partially offsets the expense and improves after-tax returns.
Research the historical assessment increase rate for the county and the local government's tax rate adjustment history. Most areas see annual increases of 2-5%. Some states cap assessment increases (e.g., California at 2% per year). Build a conservative 3-4% annual tax escalation into your pro forma projections. Major events like property improvements or area-wide reassessments can cause larger one-time increases.
