The 70 Percent Rule is a formula used to estimate the maximum price an investor should pay for a property to ensure profitability after accounting for repairs and other associated costs. According to the rule, an investor should pay no more than 70 percent of the After Repair Value (ARV) of a property minus the repair costs. This allows room for profit after expenses like closing costs, holding costs, and the costs of repairs.
