Understanding Your Results

Calculates total project cost (purchase + renovation), max loan by LTC ceiling, max loan by As-Completed LTV ceiling, identifies the binding constraint, and determines required sponsor equity cash injection.

Practical Guidance & Next Steps

Lenders always size bridge/construction loans to the lesser of the LTC ceiling and the As-Completed LTV ceiling to protect their downside if renovation costs exceed initial projections.

What is this?

A commercial property financing utility that calculates maximum debt sizing and equity requirements based on Loan-to-Cost (LTC) and As-Completed LTV caps.

How does it work?

1. Enter purchase price, renovation budget, and projected as-completed value. 2. Set lender LTC (e.g. 80%) and LTV (e.g. 70%) maximums. 3. View underwritten loan sizing, binding constraint, and required sponsor equity.

Why use it?

Ensures syndicators and developers model realistic debt leverage before bidding on value-add commercial assets.

Technical Scope & Calculation Limitations

Models standard commercial real estate bridge and construction debt underwriting standards.
