ROI, cap rate & yield.

Property returns get quoted as several different percentages that are easy to confuse. Here's what gross yield, net yield, and cap rate each measure — and how fees and vacancy quietly cut into the headline number.

Quick answer

Gross yield vs net yield vs cap rate, how expenses and vacancy erode returns, a worked $300k rental example, and how investors compute year-over-year equity growth and IRR.

Three return percentages, defined

  • Gross rental yield = Annual rent ÷ Property price × 100. The headline number, before any costs.
  • Net rental yield = (Annual rent − Annual expenses) ÷ Property price × 100. What you actually keep, relative to what you paid.
  • Capitalization rate (cap rate) = Net operating income ÷ Current market value × 100. Like net yield, but measured against today's value rather than purchase price — the standard for comparing properties.

Worked example

A $300,000 property rents for $2,000/month = $24,000/year.

  • Gross yield: 24,000 ÷ 300,000 = 8.0%
  • Now subtract annual costs — property tax and insurance, ~8% management fee, a maintenance reserve, and a vacancy allowance — say $8,000 total. Net operating income (NOI) = 24,000 − 8,000 = $16,000.
  • Net yield / cap rate: 16,000 ÷ 300,000 = 5.33%

The gross figure looked like 8%, but a third of it disappeared into costs. Always underwrite on net.

How expenses chip away at the gross

Drag on returnTypical sizeEffect
Vacancy5–8% of rentRent isn't collected 100% of the year
Management8–10% of rentPaid to a letting/management agent
Maintenance reserve1–2% of value/yrRepairs, appliances, turnover
Taxes & insuranceVaries widelyFixed annual carrying cost

Each is a percentage taken off the top, and they compound down the gross yield toward the net.

Equity growth and annualized return

Year-over-year equity growth is a percentage change: (This year's equity − Last year's equity) ÷ Last year's equity × 100. Equity rises from both price appreciation and mortgage paydown.

Total ROI combines cash flow and appreciation against cash invested. Because gains arrive over several years, investors annualize with a compound (CAGR/IRR) approach rather than simple division: Annualized return = (Ending ÷ Beginning)^(1/years) − 1. IRR generalizes this to uneven cash flows across the holding period. On typical residential rentals, "normal" total returns are often cited in the 8–12% range, but this varies enormously by market, leverage, and period — treat any single figure as a rule of thumb, not a guarantee.

Quick answers

Common questions.

Residential rental returns are often cited around 8-12% total, but this varies widely by location, leverage, and time period. Cap rates alone commonly sit in the 4-8% range. Treat any single number as a rough benchmark, not a promise.

Rental yield divides income by the price you paid; cap rate divides net operating income by the property's current market value. Cap rate is the standard for comparing properties because it uses today's value.

Gross yield ignores costs. Vacancy, management fees, maintenance reserves, taxes, and insurance each take a percentage off the top, so net yield can be a third lower than gross — 8% gross becoming about 5.3% net in a typical case.

It's a percentage change: (This year's equity - Last year's equity) / Last year's equity x 100. Equity grows from both appreciation and mortgage principal paydown.
