Why this scenario matters

DSCR lending decisions often hinge on small assumption changes. A pre-screen model reduces wasted applications and helps you negotiate from a stronger position.

Baseline modeling framework

  1. Start with conservative effective rent, not optimistic pro-forma rent.
  2. Include vacancy, management, maintenance, tax, insurance, and HOA when applicable.
  3. Run at least three rate scenarios and two vacancy scenarios.
  4. Verify lender overlays before committing capital.

Practical checklist

  • Export your assumptions before every lender call.
  • Keep a stress-case DSCR threshold of at least 1.15 for downside resilience.
  • Compare payment structure, not just headline rate.

FAQ

Q: How long do interest-only periods last? A: Typically 5–10 years. After that, payments convert to fully amortizing, increasing your monthly payment significantly.

Q: Is interest-only riskier for my exit strategy? A: Yes. You build no equity during the IO period. Plan for higher payments or refinancing before the IO term expires.

Q: Do all DSCR lenders offer interest-only? A: No. Many require 1.25+ DSCR for IO versus 1.0–1.15 for amortizing loans. Expect 0.125–0.25% rate premiums.
