Light vs Medium vs Heavy Rehab: How Scope Changes the Deal Math

Most rehab mistakes do not start with contractor bids. They start earlier, when the project is labeled “light” even though the finish level, systems work, or timeline clearly says otherwise. Scope discipline is what keeps the budget, ARV, and exit plan aligned.

1

What light rehab usually means

Light rehab is cosmetic, fast-moving, and should not depend on major systems replacement to make the deal work.

Paint, flooring, fixtures, minor kitchen and bath refreshes, hardware, curb appeal, and punch-list repairs typically fit here.

If the deal needs electrical, plumbing, roof, foundation, or major layout changes, it is not a light rehab even if the finishes themselves are simple.

2

Where medium rehab starts

Medium rehab usually means the project is still controlled, but the scope now includes enough systems, layout, or higher-touch finish work to widen both timeline and contingency.

This is often where investors get most exposed, because the project still feels manageable while carrying enough unknowns to punish sloppy underwriting.

Medium rehabs usually deserve an explicit contingency, especially if the property is older or the buyer pool expects a stronger finished product than a basic cosmetic turn can deliver.

  • Cabinet or kitchen replacement instead of simple refresh
  • Multiple bath updates
  • Some systems work
  • Meaningful extension of the timeline

When a project is truly heavy

Heavy rehab means the project has crossed into structural, gut, or systems-heavy territory where uncertainty is part of the acquisition, not an edge case.

This can include foundation work, full electrical or plumbing replacement, major HVAC replacement, extensive exterior work, or floorplan changes that require more than finish-level coordination.

Heavy projects need more than a higher per-square-foot number. They usually need a slower timeline, wider contingency, and a much more conservative view of what the exit can tolerate.

Important shift

Once the project is heavy, the exit strategy should survive if rehab takes longer and the buyer pool is less forgiving than hoped. If it only works at best case, it probably is not priced right.

Frequently Asked Questions

Can a project start light and become medium or heavy?

Yes, and that is common. Once hidden systems or structural issues appear, the math should be re-underwritten immediately instead of hoping the original scope still holds.

Should each scope use the same contingency?

No. Light rehabs may need very little contingency if the property is straightforward. Medium and heavy rehabs usually deserve a more explicit buffer because the unknowns are wider.
