Follow the default numbers.
With the example inputs shown above, the model gives maximum allowable offer: $165,000.
The formula is mao = arv × rule − repairs − assignment − reserve. Open the breakdown to trace expenses and assumptions. Change one input at a time to see how your decision changes. This example uses scenario inputs; it is not an offer, tax bill, appraisal or legal determination.
The 70% rule is a screening shortcut
The rule starts with a chosen fraction of after-repair value and subtracts repairs, the assignment fee and any additional reserve. Seventy percent is a user-adjustable convention, not a legal maximum or a universal investor requirement. Changing the rule to sixty-five or seventy-five percent can substantially change the offer. Actual holding, financing, sale and desired-profit costs belong in a full flip analysis.
An assignment fee is a deal cost
The estimated end-buyer offer is ARV times the rule less repairs and the extra reserve. The maximum seller contract price also subtracts your assignment fee. If the calculated offer is negative, the entered spread does not support a positive purchase price under this rule. Do not hide that result by rounding it up to zero.
Verify what you can assign
State licensing, marketing, disclosure and contract requirements can apply to wholesaling. This arithmetic does not establish that a contract is assignable or that advertising an equitable interest is lawful. Review the specific state rules and the contract with qualified local counsel. An assignment fee is not guaranteed income until the transaction closes.
Stress the expensive unknowns
Repair scope and ARV usually dominate the result. Put a contingency in the repair budget and run a lower resale-price scenario. Then open the prefilled house-flipping model to replace the heuristic with actual acquisition, holding, financing and selling expenses. A buyer may require a different profit margin from the one implied by your chosen percentage.
