Vacancy Rate	6%	Expected share of lost rent annually.
Annual Property Tax	$3,200	Recurring ownership tax cost.

Interest Rate	6.75%	Loan pricing used for debt service.
Holding Period	7 years	Investment horizon for exit projections.

Formula Used

Gross Scheduled Income = (Monthly Rent + Monthly Other Income) × 12
Effective Annual Income = Gross Scheduled Income × (1 − Vacancy Rate)
Annual Management Cost = Effective Annual Income × Management Rate
Operating Expenses = Taxes + Insurance + HOA + Maintenance + Utilities + Capital Reserve + Management Cost
NOI = Effective Annual Income − Operating Expenses
Monthly Mortgage Payment = P × [r(1+r)ⁿ] ÷ [(1+r)ⁿ − 1]
Annual Debt Service = Monthly Mortgage Payment × 12
First-Year Cash Flow = NOI − Annual Debt Service
Cap Rate = NOI ÷ Purchase Price
Cash on Cash Return = Annual Cash Flow ÷ Total Cash Invested
Total Cash Invested = Down Payment + Closing Costs + Rehab Costs
Projected Sale Price = Purchase Price × (1 + Appreciation Rate)^{Holding Years}
Net Sale Proceeds = Projected Sale Price − Selling Costs − Remaining Loan Balance
Total ROI = (Projected Hold Cash Flow + Net Sale Proceeds − Total Cash Invested) ÷ Total Cash Invested
Annualized ROI = [(Ending Wealth ÷ Initial Cash Invested)^{1 ÷ Years} − 1] × 100

This setup combines first-year operating performance with multi-year resale and equity assumptions.

FAQs

1) What does rental ROI mean?

Rental ROI measures how efficiently a property turns invested cash into profit. It can include annual cash flow, equity growth, appreciation, and projected exit proceeds.

2) Why is cash on cash return different from cap rate?

Cap rate ignores financing and compares NOI to price. Cash on cash return includes debt payments and compares annual cash flow to the actual cash you invested.

3) Should vacancy always be included?

Yes. Vacancy reflects turnover, nonpayment, and downtime between leases. Ignoring it usually overstates annual income and makes deals look stronger than they really are.

4) What expenses matter most in rental analysis?

Property taxes, insurance, maintenance, management, capital reserves, HOA fees, and utilities are common drivers. Financing costs also strongly affect first-year cash flow.

5) Why include capital expenditure reserves?

Capital reserves help account for future major repairs, like roofs or HVAC systems. Without them, the projected cash flow can look better than reality.

6) What does DSCR tell me?

Debt service coverage ratio compares NOI to annual debt service. A higher ratio means the property income covers loan payments more comfortably.

7) Is appreciation guaranteed?

No. Appreciation is an assumption, not a certainty. Conservative estimates usually produce more dependable underwriting and reduce the chance of overstating exit value.

8) When should I export the report?

Export after reviewing inputs and confirming the results match your scenario. CSV works well for spreadsheets, while PDF is useful for presentations and deal files.
