Frequently Asked Questions
What is the 70% rule in house flipping?
The 70% rule states that an investor should pay no more than 70% of the After Repair Value (ARV) minus the estimated repair costs, ensuring a sufficient profit buffer.
Why is Annualized ROI important for flips?
Because achieving a 20% return in 4 months corresponds to a much higher annualized compounding rate (~72%) than taking 18 months to achieve the same total dollar profit.
