This final lesson consolidates all BRRRR pitfalls and prevention strategies.
Pitfall Summary
Five areas: Appraisal/Refinance, Cash Flow Compression, Renovation, Tenant/Management, and Portfolio risks. Conservative underwriting with multiple buffers is essential.
Risk Management Framework
Conservative underwriting (ARV -5-10%, rehab +10-15%, rates +0.5-1%), multiple exit strategies, adequate reserves, diversification, and professional management transition.
Readiness Checklist
Confirm deal passes both tests with conservative assumptions. Verify 3+ months reserves. Confirm lender relationships. Ensure management capacity. Check portfolio-level leverage and liquidity.
Common Pitfalls
Ignoring cumulative cash flow erosions across a portfolio
Risk: Individual losses of $50-$100/month compound to portfolio-level negative cash flow
Monitor portfolio-level cash flow monthly and address underperforming properties promptly.
Not stress-testing portfolio against simultaneous adverse events
Risk: Multiple vacancies or rate increases at once can exceed reserves
Stress-test for 20% vacancy, 1.5% rate increases, and 10% expense growth simultaneously.
