The 40th Floor Investment Property Calculator ("the calculator") is provided for general educational purposes only. Please read the following carefully before relying on any number it produces.
Nothing on this page constitutes investment advice, a recommendation to buy or not buy a specific property, an appraisal, or a guarantee of any return. Real estate investing carries real financial risk, including the possibility of loss. Decisions about a specific property should involve your own research and, where appropriate, licensed professionals.
The calculator does not know your full financial picture, does not review actual rent rolls or leases, and does not have access to real property tax records, insurance quotes, or lender underwriting. It should not be used as a substitute for advice from a licensed real estate professional, tax preparer, accountant, attorney, or lender.
Every automated figure — vacancy rate, operating expenses, property tax, insurance, and any financing terms — is an approximation based on typical figures, not the specific property you're evaluating. See our methodology page for exactly how each number is calculated. Actual income, expenses, and returns will vary, sometimes significantly, based on the real property, its leases, its condition, and its market.
40th Floor makes no warranty, express or implied, regarding the accuracy or completeness of any estimate produced by this calculator, and is not liable for decisions made based on its output.
