Creating Accurate Renovation Budgets: A Guide for Flippers

The common shorthand is after-repair value multiplied by roughly 70%, minus the repair budget — the spread covers financing, holding costs, closing costs on both ends, and profit. The two inputs that break deals are an optimistic ARV and a repair estimate built from a walkthrough rather than contractor bids.

Underestimating the scope once walls open up, timeline slippage that stacks up interest and utilities, over-improving beyond what the neighborhood supports, and buying at a price that never had margin. Permitting delays are a quieter killer, especially on structural, electrical, or plumbing work.

You can refinance into a longer-term loan and rent it out, bring in a partner, or sell the project as-is to another investor and stop the bleeding. Holding costs compound every month, so the worst outcome is usually the decision that gets deferred. We buy in-progress rehabs directly when the math has stopped working.

Not for a direct sale — we buy as-is and price the condition into the offer. For a traditional listing it's a judgment call: cosmetic work like paint and landscaping usually returns more than it costs, while major systems (roof, foundation, sewer) rarely return their full cost and can take months to schedule. Run the numbers before you spend.
