ROI in Real Estate: How to Calculate If a Property Is Worth Buying

Real estate is one of the most popular investment categories — and one where ROI is most frequently miscalculated. People cite impressive-sounding returns while leaving out costs that would dramatically change the picture.

Here's how to calculate real estate ROI honestly, including every cost that actually matters.

Two Ways to Calculate Real Estate ROI

There are two primary methods, each useful for different purposes.

Method 1: Cash-on-Cash Return

This measures the return on your actual cash invested — particularly useful if you're using a mortgage.

Cash-on-Cash ROI = Annual Pre-Tax Cash Flow ÷ Total Cash Invested

Method 2: Total ROI

This includes equity built through mortgage paydown and appreciation.

Total ROI = (Annual Cash Flow + Equity Gained) ÷ Total Cash Invested

A Real Example: $300,000 Rental Property

Let's work through a complete example.

Purchase details:

• Purchase price: $300,000
• Down payment (20%): $60,000
• Closing costs: $6,000
• Initial repairs: $8,000
• Total cash invested: $74,000

Annual income:

• Monthly rent: $2,000 × 12 = $24,000
• Vacancy allowance (8%): -$1,920
• Effective gross income: $22,080

Annual expenses:

• Mortgage payment (P&I on $240,000 at 7%): $19,152
• Property taxes: $3,600
• Insurance: $1,200
• Property management (10%): $2,208
• Maintenance (1% of value): $3,000
• Total expenses: $29,160

Annual cash flow: $22,080 - $29,160 = -$7,080

This property has negative cash flow. That's not automatically a deal-breaker — but it means you're paying $590/month out of pocket to own it.

Cash-on-cash ROI: -$7,080 ÷ $74,000 = -9.6%

Why People Think the Same Property Is a Great Investment

Now add appreciation and equity:

• Home appreciation (4% annually): $12,000
• Mortgage principal paydown: ~$4,200 in year 1
• Total equity gain: $16,200

Total return = -$7,080 (cash flow) + $16,200 (equity) = $9,120

Total ROI = $9,120 ÷ $74,000 = 12.3%

The same property shows -9.6% cash-on-cash ROI but +12.3% total ROI. Neither is wrong — they measure different things. The total ROI includes paper gains you can't spend until you sell.

The 1% Rule: A Quick Filter

Many real estate investors use the 1% rule as a quick filter: monthly rent should equal at least 1% of the purchase price.

$300,000 property → needs $3,000/month rent to pass the 1% rule.

In most major cities today, properties rarely meet the 1% rule. In some Midwest markets, they still do. The rule isn't absolute but helps quickly screen out properties with poor cash flow potential.

What Makes a Good Real Estate ROI?

There's no universal "good" ROI for real estate because it depends on your goals:

• Cash flow focused investors: Want 6–10%+ cash-on-cash return
• Appreciation focused investors: May accept negative cash flow in high-growth markets
• BRRRR investors: (Buy, Rehab, Rent, Refinance, Repeat) — target 15–25%+ ROI through value-add

Compare real estate ROI to alternatives: S&P 500 index (10% historical average), REITs (8–12%), bonds (4–6%). Real estate needs to clear those benchmarks to justify its illiquidity and management burden.
