Commercial Real Estate vs Residential: How Financing Differs
How Underwriting Differs
Residential mortgage underwriting follows standardized guidelines set by Fannie Mae and Freddie Mac, emphasizing debt-to-income ratios, credit scores, and appraisal standards within a heavily regulated framework.
Commercial real estate underwriting prioritizes the property itself. The borrower matters, but the asset drives the deal. Lenders assess income potential, occupancy rates, lease terms, market dynamics, and physical condition rather than primarily evaluating borrower finances.
Key Metrics: Residential vs Commercial
| Factor | Residential | Commercial |
|---|---|---|
| Primary metric | DTI (debt-to-income) | DSCR (property cash flow) |
| Loan terms | 15 or 30 years fixed | 5, 7, 10-year fixed; 25–30 yr amortization |
| LTV | Up to 97% (conforming) | 65–80% typical |
| Appraisal approach | Comparable sales | Income approach primary |
| Down payment | 3–20% | 20–35% typical |
| Rate type | 30-year fixed common | Balloon with amortization common |
| Personal income | Primary qualifier | Secondary to property income |
Loan Terms and Structure
Commercial loans typically feature shorter fixed-rate periods with longer amortization schedules. The structure involves a 5, 7, or 10-year fixed rate with a 25 to 30-year amortization schedule, resulting in balloon payments at maturity, requiring refinancing rather than thirty-year holds.
The Role of the Entity
Commercial properties are purchased through LLCs or business entities with personal guarantees from principals, contrasting residential purchases made in personal names.
Speed and Process
Commercial loan processes require 45 to 60 days typically, involving extended appraisals, environmental reviews, and committee approvals, considerably lengthier than residential transactions.
Where to Start
Success requires understanding key underwriting metrics, appropriate loan structures, and specialization within specific asset classes, with commercial brokers providing valuable expertise.
