此計算機如何運作？
ARV is the estimated post-renovation sale price of a property. Profit = ARV − purchase price − repair costs − holding costs − selling costs. The 70% rule sets a maximum offer of ARV × 70% − repairs as a quick deal filter. Enter all five inputs to see net profit, ROI and whether the deal passes the rule.
公式
How this is calculated
After Repair Value (ARV) is the estimated market price of a property once all planned renovations are complete. Real estate investors determine ARV by comparing the renovated property to recently sold, similarly improved homes in the same area ("comps"). The ARV is the starting point for evaluating whether a deal is worth pursuing.
The 70% rule is a common investor heuristic: never pay more than 70% of the ARV minus the estimated repair costs. This buffer is designed to cover holding costs, selling costs and leave a margin for the unexpected. Max offer = ARV × 0.70 − Repair Costs. Selling costs in the US typically run 6–8% in 2026 and include agent commissions (3–6%), closing costs and transfer taxes; adjust the percentage to match your market.
All figures are estimates — actual ARV depends on appraisal and market conditions at the time of sale. Construction costs routinely overrun budgets, so build in a contingency of 10–20% on the repair figure. The ROI shown is calculated on the total capital deployed (purchase + repairs + holding), not on borrowed funds, so leveraged returns will differ significantly.
常見問題
ARV is based on comparable sales ("comps") of renovated properties nearby. Look at homes of similar size, age and finish quality that sold within the last 90 days within 1–2 km. The average or median sale price per square metre of those comps, applied to your property, gives the ARV.
The 70% rule says an investor should pay no more than 70% of the ARV minus repair costs: Max Offer = ARV × 0.70 − Repairs. It leaves a margin to cover holding costs, selling costs and unexpected overruns while still generating a profit.
Include: purchase price, all repair and renovation costs (add a 10–20% contingency), holding costs (loan interest, property tax, insurance, utilities during renovation), and selling costs (agent commissions, closing costs, transfer taxes — typically 6–8% of the sale price in the US).
