Calculate These 6 Numbers Before Buying ANY Investment Property

Quick Overview

Investors must calculate six essential numbers before purchasing any investment property to avoid speculation and ensure profitability, with the most crucial metrics for long-term wealth building being Equity and Cash on Cash Return, rather than just the absolute monthly cash flow figure.

Key Points: The first essential number is Current Value, which investors must determine accurately, preferably through an appraisal or agent comps that account for AS IS condition, because "you do not want to pay more than current value for a property." Equity is the most important real estate financial metric, defined as asset value minus liabilities, and investors must aim to "walk into equity on day one," meaning acquiring equity without paying for it upfront through discounts or forced appreciation. After Repair Value (ARV) dictates profitability, especially for flips or BRRRR deals, and investors must be conservative, asking agents for the "middle to the low-end ARV, not the tippity top," to protect against overestimating future sales prices. Rent Comps are cited as potentially the most important metric for rental property owners, requiring conservative underwriting where investors discount stated rent expectations by about 20% or take the low end of comps to ensure realistic performance. Holding Costs significantly impact profitability for both flippers (debt service, utilities) and landlords (maintenance, capital expenses, vacancy, property management), and investors must budget for 2-3 months longer than anticipated, especially new flippers who should double their time frame. Cash flow is calculated as gross revenue minus all expenses (including vacancy, capex, and management), but Cash on Cash Return (annual cash flow divided by total invested capital) is the superior metric because it "measures efficiency." Investors should utilize resources like the book "Real Estate by the Numbers" or the Bigger Pockets calculator (with a Pro membership) to run these six numbers confidently before making an offer.
