Completion Guaranty
A completion guaranty is a personal or corporate guaranty given by the sponsor of a commercial real estate construction project, obligating the guarantor to complete construction in accordance with the loan documents — even if construction costs exceed the loan budget.
Completion guaranties are the construction lender's primary tool for managing cost-overrun risk. The lender does not want to fund unlimited cost overruns from the loan, so the sponsor personally (or via a corporate guarantor with adequate liquidity) promises to complete the project. If construction costs exceed the budget, the sponsor must contribute equity to cover the overrun. The guaranty typically survives until completion and stabilization.
Completion Guaranty Scope
Construct the project in accordance with the plans and specifications, lien-free; cover any cost overruns from sponsor equity; achieve substantial completion by a defined date (often with extension provisions for force majeure); satisfy any final lender funding conditions (certificate of occupancy, final lien releases, as-built survey).
Carve-Out vs Full Recourse Completion Guaranty
Most completion guaranties are full personal recourse to the sponsor or designated guarantor — meaning the guarantor is personally on the hook for any cost overrun. Some sophisticated structures negotiate caps (a stated maximum dollar exposure) or fall-away provisions (the guaranty terminates upon a defined construction milestone).
Net Worth and Liquidity Covenants
Completion guarantors typically must maintain a stated minimum net worth (often 1.5–2x the loan amount) and minimum liquidity (often 5–10% of the loan amount) throughout the construction period. Failure to maintain these covenants is typically a default.

The concept
- What is a completion guaranty?
- A sponsor’s promise to a construction lender to finish the project on time and pay any cost overruns.
- What is a corporate lease guaranty?
- A parent company guarantees a subsidiary tenant’s lease, so the landlord relies on the parent’s credit.
- What is a tenant personal guaranty?
- An individual (often the business owner) guarantees a lease. Common with small-business tenants.
- What is a good-guy guaranty?
- The guarantor is released if the tenant gives notice, pays rent through move-out and leaves the space in good condition.
- Why do landlords care about the guarantor’s credit?
- A guaranty is only as good as the guarantor’s assets.
Work the numbers
- A $15M construction project runs $1.2M over budget. Who pays under a completion guaranty?
- The sponsor.
- A tenant owes 5 years at $60,000 a year. Full personal guaranty exposure?
- Up to $300,000 plus costs, less any re-leasing income.
- Same lease with a 12-month cap?
- $60,000.
- A good-guy guaranty: tenant gives 6 months’ notice and pays through move-out. Exposure after?
- None for the remaining term.
- A national parent guarantees a $200,000 lease vs. a local LLC with no guaranty. Cap rate effect?
- Investors pay a lower cap rate for the parent’s credit, raising value.

Frequently Asked Questions
What is a completion guaranty?
A personal or corporate guaranty given by the sponsor of a construction project, obligating the guarantor to complete construction in accordance with the loan documents even if costs exceed the loan budget. Required on essentially every commercial construction loan.
Who signs the completion guaranty?
The sponsor principal personally (most common on smaller deals) or a designated corporate or family-office guarantor with adequate net worth and liquidity (most common on larger deals where the principal does not have personal net worth sufficient to support the guaranty).
When does the completion guaranty terminate?
Typically upon substantial completion, satisfaction of final lender funding conditions, and (sometimes) achievement of a stabilization milestone. The guaranty may convert into a more limited recourse carve-out structure post-completion.
Can completion guaranties be capped?
Yes — sophisticated borrowers negotiate dollar caps on completion guaranty exposure, particularly on larger deals where the unbounded liability would be unworkable for the guarantor. Caps are not standard on smaller deals.
