Calculator Best Practices
📊 Use Conservative Estimates
Better to be pleasantly surprised than disappointed:
- • Rent: Use median comparable, not highest
- • Vacancy: Budget 7-10% even in strong markets
- • Expenses: Add 10% buffer to estimates
- • Appreciation: Don't count on it for cash flow analysis
🎯 Set Your Minimum Criteria
Pre-define deal requirements before analyzing:
- • Minimum monthly cash flow: $100-200
- • Minimum CoC return: 8%
- • Minimum cap rate: 6%
- • Maximum cash needed: Your budget
- Pass immediately if property doesn't meet minimums
🔄 Compare Multiple Scenarios
Run variations to understand sensitivity:
- • Different down payment amounts (20%, 25%, 30%)
- • Various interest rates (+/- 0.5%)
- • Rent variations (+/- $100/month)
- • With/without property management
💾 Save Your Analyses
Build a database of analyzed properties:
- • Track all properties you've evaluated
- • Compare deals side-by-side later
- • Return to properties that improve (price drops)
- • Learn from patterns in good vs. bad deals
Common Calculator Mistakes
❌ Forgetting CapEx Reserves
Always include $200-300/month for roof, HVAC, water heater replacement. These WILL need replacing.
❌ Using Asking Rent Instead of Market Rent
That $2,500 asking rent might sit empty. Use actual rented comparables, not hopeful listings.
❌ Not Including Property Management
Even if self-managing initially, budget 8-10%. You might need/want PM later. Calculate worst-case.
❌ Ignoring Vacancy
"I'll keep it rented 100%!" No you won't. Budget 7-10% vacancy or face surprise losses during turnover.
