Understanding Commercial Mortgages

Key concepts every CRE borrower should know before applying.

Amortization vs. Loan Term

Commercial mortgages typically amortize over 20–25 years but have a balloon payment (loan term) of 5–10 years. At term end, the remaining balance must be refinanced or paid in full. This structure keeps payments lower while giving lenders flexibility.

What Affects Your Rate?

Commercial mortgage rates depend on property type, LTV ratio, DSCR, borrower experience, loan size, and market conditions. Owner-occupied properties with SBA backing can get rates 0.5–1.5% lower than investor properties.

Down Payment Requirements

Most commercial mortgages require 20–30% down. SBA 504 loans offer 10% down for owner-occupied. Higher down payments improve DSCR, lower your rate, and increase approval likelihood on marginal deals.

Closing Costs to Expect

Budget 2–5% of the loan amount for closing costs: appraisal ($3K–$8K), environmental ($2K–$5K), legal fees, title insurance, origination fee (0.5–1%), and lender due diligence. BestLoanUSA charges no upfront advisory fees.

Frequently Asked Questions

Common questions about commercial mortgage financing.

How is a commercial mortgage different from a residential mortgage?

Commercial mortgages typically have shorter terms (5–10 years vs 30 years), higher rates, larger down payments (20–30%), and qualification is based primarily on the property's income (DSCR) rather than personal income alone. They also commonly feature balloon payments at the end of the term.

What is a balloon payment in commercial lending?

A balloon payment is the remaining loan balance due at the end of the loan term. For example, a loan with 25-year amortization but a 10-year term will have a large balance remaining after 10 years that must be refinanced or paid in full. This calculator shows your projected balloon balance.

Can I get a 30-year fixed commercial mortgage?

True 30-year fixed rates are rare in commercial lending. SBA 504 loans offer 20–25 year fixed-rate portions. Most conventional commercial mortgages have 5–10 year terms with 20–25 year amortization schedules and a balloon payment at maturity.

What credit score do I need for a commercial mortgage?

Most conventional CRE lenders require 680+. SBA loans typically need 680–700+. DSCR loans focus on property income and may accept 660+. Bridge and private lenders may work with 620+ but at higher rates.
