How it's calculated

Maximum offer
After-repair value × 70% − repair costs.
Why 70%
The other 30% is meant to cover closing, holding and selling costs plus your profit. Some investors use 65% in slow markets or 75–80% in hot ones.

What's a good result?

The rule is a quick screen, not a full analysis: high-priced homes, long rehabs or expensive financing can need a lower percentage.

Questions

Is the 70% rule still realistic?

In competitive markets many flippers pay more, accepting a thinner margin. Run the full numbers before going above it.

What does the fix and flip calculator add?

Your actual financing, holding time and selling costs, so you see the profit and return, not just a ceiling.
