Frequently asked questions

What is After Repair Value (ARV)?

ARV represents the estimated future selling price of the property once all planned renovations, modernizations, and staging are fully completed. It is calculated by looking at recent sales of comparable updated properties in the near school districts or neighborhoods.

The 70% rule states that an investor should pay no more than 70% of the After Repair Value (ARV) minus the estimated cost of repairs. For example, if a house's ARV is $300,000 and repairs will cost $50,000, the maximum purchase offer should be $160,000 ($210,000 minus $50,000).
