How to finance commercial real estate? A practical guide to loan types, underwriting requirements, and strategies for securing the best CRE financing.
Financing is the lever that makes commercial real estate investment possible for most buyers — and getting the financing right is as important as getting the property right. The wrong financing structure can squeeze cash flow, limit flexibility, and turn a good property into a frustrating investment. The right structure enhances returns, provides stability, and gives you the operational freedom to execute your business plan.
Here’s a comprehensive guide to financing commercial real estate — from understanding your options to securing the best possible terms.
The Foundation — Understanding CRE Loan Underwriting
Before exploring specific loan types, understand how commercial real estate lenders think:
Debt Service Coverage Ratio (DSCR)
DSCR = Net Operating Income ÷ Annual Debt Service
Most lenders require a minimum DSCR of 1.20x to 1.35x. This means the property must generate at least 20–35% more income than needed to cover debt payments. Properties with stronger DSCR qualify for better rates and terms.
Loan-to-Value (LTV)
LTV = Loan Amount ÷ Appraised Value
Most commercial lenders cap LTV at 65–75% for stabilized properties. Higher equity requirements in commercial real estate reflect the greater complexity and risk compared to residential lending.
Property Cash Flow Quality
Lender underwriting emphasizes the stability and durability of the property’s income — tenant credit quality, lease term remaining, vacancy risk, and operating expense predictability all affect lender willingness and pricing.
The Major Commercial Real Estate Financing Options
Conventional Commercial Mortgages
Bank and institutional lender loans for stabilized, income-producing properties. Competitive rates for qualified borrowers, flexible structures, but full recourse to the borrower in most cases.
SBA 504 — The Owner-Occupant Advantage
For business owners purchasing owner-occupied commercial real estate, the SBA 504 is the most powerful financing tool available:
- 10% down payment
- Below-market fixed rates on the SBA portion
- 20–25 year amortization
- Loan amounts up to $5.5 million
CMBS Loans
Securitized commercial mortgages offering competitive fixed rates for larger stabilized assets ($2 million+). Non-recourse structure is a significant advantage — offset by strict prepayment penalties and limited modification flexibility.
Bridge Loans
Short-term (12–36 month) financing for transitional assets or time-sensitive closings. Higher rates than permanent financing — appropriate when the property doesn’t yet qualify for permanent debt or when speed is essential.
Mezzanine and Preferred Equity
For borrowers seeking higher leverage, mezzanine debt and preferred equity fill the gap between senior debt and common equity. Higher cost but enables deals that require leverage above conventional limits.
Strategies for Securing the Best Financing
- Shop multiple lenders simultaneously: Banks, CMBS lenders, life insurance companies, and debt brokers all have different appetites and pricing
- Present your deal compellingly: A well-prepared package — detailed proforma, rent roll, operating history, business plan — reduces perceived risk and improves pricing
- Optimize your DSCR before going to market: Improving
