Retainage (Retention)
A portion of each construction payment — commonly 5–10% — withheld until the project is substantially or fully complete, ensuring the contractor finishes the work and corrects any defects before receiving the final money.
Retainage (also called retention) is the practice of holding back a percentage of each progress payment to a contractor — typically 5% to 10% — until the job is substantially or fully complete. It's a financial incentive that keeps the contractor on the project through the punch-list and warranty phase, because the accumulated retainage is only released at the end.
Where it sits in a construction deal
Retainage appears in two related places on a fix-and-flip or new construction loan:
- Owner-to-contractor — the investor (or the construction contract) withholds retainage from each payment to the general contractor.
- Lender-to-borrower — the lender may build retainage into the draw schedule itself, releasing only part of each draw and holding the rest until completion is verified.
A worked example
Rehab budget: $100,000, 10% retainage
Draw #1 work completed: $30,000
Released now: $27,000
Retained: $3,000
... repeated across draws ...
Total retained over the project: $10,000
Released only after final inspection + punch-list complete
(often after the certificate of occupancy and lien waivers).
The $10,000 retainage is the contractor's incentive to finish strong and fix defects — walk away early and they forfeit it.
Why it matters in investor lending
Retainage protects against the classic risk that a contractor takes the easy 90% of the work, gets paid, and disappears before the hard finish details. By withholding the final slice, both the investor and the lender ensure the project reaches true completion — which is what supports the property's as-is value at sale or the appraised value for a refinance takeout.
How it's used in investor lending
Negotiate the retainage percentage and release conditions in your construction contract up front — contractors will push for lower retainage and faster release; you want enough held to guarantee completion. Coordinate it with lien waivers (release final retainage only against an unconditional final waiver) and the final draw. Some states cap retainage percentages by statute, so check local rules. Done right, retainage costs you nothing and dramatically de-risks the back end of a rehab or build.
This is general information, not legal advice; retainage rules vary by state.
Frequently asked questions
How much retainage is typical?
Commonly 5% to 10% of each progress payment, held back until the project is substantially or fully complete. The exact figure is negotiated in the construction contract, and some states cap the percentage by statute. The goal is to retain enough to keep the contractor motivated to finish without straining their cash flow excessively.
When is retainage released?
Typically after the work is substantially complete and the punch-list is finished — often tied to final inspection, the certificate of occupancy, and an unconditional final lien waiver from the contractor. Defining the exact release conditions in the contract up front prevents disputes at the end of the job.
Is retainage the same as a holdback?
They're related but not identical. Retainage specifically refers to withholding a percentage of construction payments until completion. A holdback is a broader term for any funds a lender reserves and releases under conditions — which can include construction retainage, but also repair escrows or other reserves.
