Financial Formulas & Calculations
Monthly Payment (PMT)
PMT = P × [r(1+r)^n] / [(1+r)^n - 1]
P = Principal, r = Monthly rate, n = Total payments
Example: $200,000 @ 4.5% for 30 years = $1,013.37/month
Example: $200,000 @ 4.5% for 30 years = $1,013.37/month
Cap Rate
Cap Rate = (NOI / Purchase Price) × 100
NOI = Annual rent - Operating expenses
Example: $24,000 NOI / $300,000 = 8% Cap Rate
Example: $24,000 NOI / $300,000 = 8% Cap Rate
Cash Flow
Cash Flow = Rent - Expenses - Debt Service
Monthly: $2,500 - $875 - $900 = $725
Annual: $725 × 12 = $8,700
Annual: $725 × 12 = $8,700
Cash-on-Cash Return
CoC = (Annual Cash Flow / Cash Invested) × 100
$8,700 annual CF / $50,000 invested = 17.4%
Good: >8%, Excellent: >12%
Good: >8%, Excellent: >12%
Equity
Equity = Property Value - Mortgage Balance
$300,000 value - $180,000 mortgage = $120,000
Equity % = 40% (120k/300k)
Equity % = 40% (120k/300k)
Loan-to-Value (LTV)
LTV = (Loan Amount / Property Value) × 100
$180,000 loan / $300,000 value = 60% LTV
Lower LTV = More equity, less risk
Lower LTV = More equity, less risk

💡 Tip: Use the time projection feature to see your total return at sale month
BRRR Strategy
Buy, Rehab, Rent, Refinance, Repeat
- Initial Purchase & Rehab:
- Follow Fix-and-Flip steps 1-2
- Use total project cost as purchase price
- Refinance (Simulated):
- Add "Sell" event at month 6 with ARV price
- Immediately add new "Buy" event at same month
- Enter same property address and ARV as new purchase price
- Set 20-25% down payment (standard refinance terms)
- Enter market rent for the property
- Add realistic monthly expenses
- Hold & Repeat:
- Property now shows rental income
- Use cash from refinance for next BRRR deal
- Add new properties following same pattern
💡 Tip: Track your "Total Cash on Hand" to see available capital for next deal

Tips & Best Practices
- Accurate Expenses: Include all costs - insurance, taxes, maintenance, HOA, utilities
- Conservative Estimates: Better to overestimate expenses and underestimate income
- Timeline Planning: Set realistic months for each event
- Regular Reviews: Use time projections to plan 5+ years ahead
- Multiple Scenarios: Save different simulations to compare strategies
Common Scenarios
House Hacking
- Buy property with low down payment (3-5%)
- Set rent = income from other units/rooms
- Set expenses = your portion after tenant contributions
💡 How to Simulate a Refinance
Cash-Out Refinance Workflow:
- Add a Buy event at the Total Project Cost (initial purchase)
- Add a Sell event at the new ARV (represents the post-rehab appraisal)
- Add a Buy event at ARV × (1 - cash-out percentage)
- Example: For 70% cash-out refi, use ARV × 0.30 as the new buy amount
- This simulates keeping 30% equity and pulling out 70% cash
Why this works: The sell/rebuy sequence mimics pulling cash out while maintaining ownership. Your "Cash from Sales" will show the refinance proceeds.
Partnership Deals
- Enter your portion of down payment
- Set rent and expenses to your ownership percentage
- Track your actual cash flow and returns
