What is a commercial construction loan?
A commercial construction loan finances new commercial building construction or major renovation. Loans typically structure as: 12-24 month construction phase with monthly interest-only draws, followed by conversion to permanent take-out financing OR balloon payoff. Most construction loans require 25-35% borrower equity, 680+ credit, signed construction contracts, builder qualifications, and detailed budgets. Rates: 6-12% APR during construction. SBA 504 offers 10% down for owner-occupied construction.
Commercial Construction Financing Overview
Commercial construction loans fund the development or major renovation of commercial real estate. Unlike a permanent mortgage, construction loans are short-term (12–36 months) and disbursed in stages (“draws”) as construction milestones are completed. When construction is complete, the loan converts to or is replaced by permanent financing.
Types of Commercial Construction Loans
Construction-to-Permanent Loans (C2P)
A single loan that covers both construction and permanent phases. During construction: interest-only payments on drawn amounts. After completion: converts to amortizing permanent mortgage automatically. Saves on closing costs vs. two separate loans. Best for owner-occupied commercial properties.
SBA 504 Construction Loan
The SBA 504 program covers ground-up construction and major renovations for owner-occupied commercial property. Structure: 50% conventional lender + 40% CDC + 10% borrower. The SBA portion locks in below-market fixed rates (typically 6.5–9%). Up to $14M total project with $5.5M SBA portion.
Conventional Construction Loan
Bank-provided construction lines of credit disbursed against inspected milestones. Typically 70–75% LTC (loan-to-cost) or 65% LTV (loan-to-value) of completed appraised value. 12–24 month term, Prime-based or SOFR-based floating rate. Requires experienced general contractor and architect’s plans.
