How House Flip Math Works
House flipping requires extremely rigid mathematical discipline because profits are fundamentally locked in exactly on the day you buy the property, not the day you sell it.
Our calculator aggressively implements the industry-standard 70% Rule to determine your Maximum Allowable Offer (MAO). Investors should strive to pay no more than 70% of the After Repair Value (ARV) minus all estimated repair costs.
To guarantee real-world accuracy, the model forces you to budget for hidden holding costs—typically 1% of the purchase price per month—which relentlessly bleed profit through hard money interest, taxes, utility bills, and insurance.
Exit fees are frequently underestimated by novice flippers. We inherently subtract the hefty 6% to 8% lost cleanly to seller broker commissions and buyer closing concessions.
By subtracting your calculated rehab, holding, and exit expenses from the final ARV, this tool perfectly isolates your net cash profit and annualized Return on Investment (ROI).
Consistently utilizing this rigorous approach prevents emotional buying, ensuring investors only commit capital to properties mathematically capable of surviving inevitable market fluctuations or construction delays.
Frequently Asked Questions
The 70% Rule states that a rational investor should boldly pay absolutely no more than 70% of the After Repair Value (ARV) minus the definitively estimated cost of renovations.
Holding costs universally include ongoing property taxes, hazard insurance, utility bills, HOA fees, and significantly, the massive monthly interest payments strictly owed to hard money lenders or private investors.
Exit fees routinely hover around 6-8% of the final home sale price, accurately accounting for the mandatory 5-6% real estate agent commissions plus an additional 1-2% legally required for standard buyer closing concessions and title policies.
ARV is intensely calculated by having an appraiser or seasoned agent aggressively find extremely recent sales comps of similar square footage that have been painstakingly fully renovated to the exact same visual standard.
Experienced professional investors actively target a minimum strict cash-on-cash ROI of 15% to 20% to adequately justify the heavy operational risk, contractor headaches, and lengthy time commitment inherently required.
Hard money is vastly popular for aggressive flips because traditional mainstream banks steadfastly refuse to lend on heavily distressed assets. While structurally expensive, it rapidly provides the crucial liquidity needed to competitively win fast cash offers.
