Plain-English explanation

How to read this number

What this tells you

  • A larger rehab budget can lower projected flip profit or increase cash left in a BRRRR deal.
  • Contingency helps model surprises before they become cash problems.
  • Rehab estimates should be tied to scope, timeline, and local labor costs.

What this does not tell you

  • This does not replace contractor bids, permits, inspection findings, or structural review.
  • It does not guarantee final project cost.

Common mistakes

  • Leaving out permits, utilities, cleanup, holding time, and contingency.
  • Using rehab numbers that do not match the target finish level.
Questions investors ask

FAQ

How much contingency should I add?

Many investors model a contingency percentage, but the right amount depends on scope, age, inspection findings, and contractor certainty.
