Purchase

%

Added to total cash to close. May be funded by 2nd loan.
Drives cap rate, equity, appreciation, and sale proceeds. Default assumes 70% of reno cost flows to value.

First loan

Principal + interest
Interest only
Monthly payment (1st loan)

Second loan

Principal + interest
Interest only
Monthly payment (2nd loan)
Set balance to 0 if no second loan.

Operating expenses

Sale assumptions

Headline IRR & Equity Multiple assume a 30-year hold (to loan payoff). The projection table and IRR chart show IRR for every year 1–30 — use those to evaluate shorter hold periods.
Typically 6–8% (realtor commissions + closing). Pre-tax IRR — does not include capital gains tax or depreciation recapture.

Performance

Monthly cash flow i
Profit or shortfall left in your pocket each month after collecting rent and paying all operating expenses, reserves, and debt service.
EGI − opex − debt service
Cash-on-cash return i
Your first-year return on the cash you personally put into the deal. Debt-adjusted — reflects how financing amplifies (or dilutes) returns.
Annual cash flow ÷ cash invested × 100
Strong ≥ 8% · OK 4–8% · Weak < 4%
Cap rate i
Annual income yield on property value, ignoring financing. Used to compare properties apples-to-apples regardless of loan structure.
Annual NOI ÷ property value × 100
Strong ≥ 6% · OK 4–6% · Weak < 4%. Luxury/coastal markets often trade 3–5% because buyers pay for future appreciation.
Net operating income i
annual, before debt
The property's annual profit from operations, before mortgage payments. This is what the property generates independent of how it's financed — appraisers use it to value commercial real estate.
Gross income − vacancy − all operating expenses
Break-even occupancy i
What occupancy rate the property needs to just cover expenses and debt. Lower = more vacancy cushion before you lose money.
(Opex + debt service) ÷ gross rent × 100
Strong ≤ 80% · Tight 80–90% · Very tight > 90%
Annual cash flow i
Yearly profit after all expenses and debt service. What would be left at year-end if rent, vacancy, and expenses match your inputs.
Monthly cash flow × 12
IRR (30-yr hold) i
Your annualized return over a 30-year hold, including cash flow, loan paydown, appreciation, and eventual sale proceeds (net of selling costs). Pre-tax — doesn't account for capital gains or depreciation recapture.
Strong ≥ 12% · OK 8–12% · Weak < 8%
Equity multiple (30-yr hold) i
Total dollars returned for every dollar invested, over the full hold period. An equity multiple of 3× means you get $3 back for every $1 in.
(Total cash flows + net sale proceeds) ÷ initial investment
Strong ≥ 2.5× · OK 1.5–2.5× · Weak < 1.5×
Years to positive IRR i
The first year at which selling the property produces a positive annualized return. Early years typically show negative IRR because one-time frictions (closing costs, selling commission) dominate before appreciation and cash flow catch up. Typical range: 7–12 years.

Rules of thumb

Rent-to-price ratio i
Monthly rent as a percentage of purchase price. A quick screening tool investors use before running deeper numbers.
Monthly rent ÷ purchase price × 100
Strong ≥ 2% (the "2% rule") · OK 1–2% (the "1% rule") · Weak < 1%. Hard to hit in most appreciation markets today.
Investment-to-rent ratio i
How many years of gross rent equal your total cash plus loan into the deal. Like the traditional "Gross Rent Multiplier" but uses your total investment instead of just purchase price — more honest when there's significant rehab spend.
(Purchase + renovation + closing) ÷ annual gross rent
Strong ≤ 8× · OK 8–12× · Weak > 12×. Lower is better.
DSCR i
Debt Service Coverage Ratio — how many times over the property's income covers its mortgage. This is the metric lenders use to decide whether to approve an investor loan.
Annual NOI ÷ annual debt service
Strong ≥ 1.25× (meets most lender minimums) · Marginal 1.0–1.25× (covers debt, no cushion) · Weak < 1.0× (property doesn't cover mortgage; you'd subsidize from other income)

Property value, loan balance, equity over time

Monthly cash flow

Year-1 expense breakdown (where each dollar goes)

Annual + cumulative cash flow over time


Reading the metrics & projection: Two kinds of numbers on this page. Operational (cash flow, COC, cap rate, break-even) measures year-by-year profitability while you hold. Total return (IRR, equity multiple, Total ROI) measures annualized return if you sell that year, net of 7% selling costs and loan payoff. A property at operational break-even can still show deeply negative IRR in early years because one-time friction (closing costs, furnishing, renovation ROI < 100%, and the eventual 7% selling commission) needs to be overcome by cumulative appreciation + cash flow. The "Years to positive IRR" card shows when that crossover happens — usually 7–12 years.

IRR column: annualized pre-tax rate of return if you sold at the end of that year, net of selling costs and remaining loan balances. A higher IRR in earlier years is typical — leverage benefit peaks early and diminishes as debt pays down.
