Underwrite
Run property research, repair assumptions, offer math, financing, holding costs, and risk flags before you commit.
Protect the flip margin from offer to sale.
Use defensible comps to buy right, turn the walkthrough into scope, control every construction dollar, and carry the property through listing and close.

A flip screen with the costs the 70% rule compresses
Illustrative numbers, not a market study. Purchase $210,000. After-repair value $340,000 from renovated comps. Repairs $48,000. Buying costs 2% of price. Selling costs 8% of ARV. Financing and holding $14,000.
Buying costs$4,200
Selling costs$27,200
All-in project cost$303,400
Projected profit$36,600
70% rule offer$190,000
The detailed model still shows profit at $210,000, but the quick rule says $190,000. The gap is the point. If your financing, hold, or sale costs are heavier than the 30% cushion, the rule is the tighter ceiling. If the seller will not move under the ceiling you choose, do not average the two numbers and call it a compromise.
Common questions
What this strategy page will and will not decide for you.
What does house flipping software need on day one?
A value you can trace to comps, a repair scope, and the buying, holding, financing, and selling costs. Project management matters after you own the house, not instead of the offer math.
Is the 70% rule the whole analysis?
No. It is a screen. The maximum-offer calculator and the profit calculator show the full stack. Read the 70% rule guide before you treat the shortcut as a bid.
When should I walk away?
When the seller's price is above the ceiling that still pays your target after repairs, time, and sale costs, and you cannot cut scope without changing the comps you used for ARV.
Can the same file track the rehab?
Yes. The approved scope becomes the budget. Receipts and changes update projected profit so the offer model is not a forgotten spreadsheet.
Does this replace an appraisal or a contractor?
No. You still verify comps, inspections, and bids. The software keeps those decisions in one place.
Keep the numbers, work, files, and outcome connected.
