Quick Answer
A 5-10% rent decline can drop DSCR by 0.10-0.25, potentially pushing marginal properties below qualification thresholds. On a property with $2,000 monthly rent and $1,600 debt service (1.25 DSCR), a 10% rent reduction to $1,800 drops DSCR to 1.125—below most lender minimums. Model rent decline scenarios to ensure your DSCR remains above 1.15-1.20 under stress conditions.
Key Takeaways
- 5% rent decline ≈ 0.10-0.15 DSCR reduction on typical investment property
- 10% rent decline ≈ 0.20-0.25 DSCR reduction, potentially below 1.25 qualification threshold
- Marginal DSCR properties (1.20-1.25) are most vulnerable to rent declines
- Stress test all acquisitions at 5-10% rent reduction before committing capital
- DSCR cushions matter: Target 1.30+ DSCR to absorb market downturns
FAQ
Q: How much rent decline should I stress test? A: Model 5%, 10%, and 15% declines. Most underwriters will haircut your stated rent by at least 5% anyway.
Q: What if my DSCR falls below 1.0 after stress testing? A: Reduce your loan amount request, increase reserves, or target properties with higher yield cushions.
Q: Does this apply to short-term rentals? A: STR income is more volatile. Run additional scenarios with 20-30% rent decline to account for seasonality and market shifts.
