Commercial real estate is a good investment when the price you pay leaves the rent enough room to beat a government bond and cover the loan, and when you can hold the building through a downturn. Three choices decide the result: the property type, the price and the borrowing.
A building pays its owner in two ways. Net operating income (NOI) is the rent left after operating costs and before loan payments. The change in the building's price is the second part, and it arrives only when you sell or refinance. The total return adds the two.
| What works for the owner | What works against the owner |
|---|---|
| Rent under leases that often run for years | Prices can fall far and take years to recover |
| A price that can rise with the rent | A sale takes months, and the whole building goes at once |
| Tax deductions for the building's cost | A loan magnifies every price change |
| Property types with different cycles | An empty building still costs taxes, insurance and upkeep |
The pillar guide charts how far US commercial property prices fell after 2007 and 2023, with a table on how borrowing changes the cash return.
Investors buy commercial buildings for three reasons:
- Income. Tenants pay rent under signed leases. Under a triple net lease, the tenant also pays the property taxes, insurance and maintenance.
- Growth. A building's value follows its NOI, so a rent increase raises the price a buyer will pay. The valuation guide shows how cap rates and NOI turn income into value.
- Choice. Offices, warehouses, stores, apartments and medical buildings each follow their own demand, so one type can gain while another loses.
Each reason can fail, and the sections below measure how often it did.
No property type holds the top spot for long: in 2025, health care REITs returned 28.5% and office REITs lost 14.0%, according to Nareit. The type of building you own can matter more than owning real estate at all.
A real estate investment trust (REIT) is a company that owns income-producing buildings and sells shares in them on a stock exchange. Nareit, the REIT industry's trade association, publishes the total return of listed REITs by property type, dividends included (Nareit, returns by property sector). That record gives a public price for each kind of building, year by year.
Source: Nareit, Investment Performance by Property Sector and Subsector, September 30, 2026: 2025 total returns of the FTSE Nareit All Equity REITs index and nine of its property sectors.
The ranking also turns over fast. Data center REITs, last of the nine sectors in 2025, returned 28.0% from January to September 2026. Lodging and resort REITs returned 37.6% over the same nine months, after losing 5.1% in 2025. Health care stayed near the top, at 18.9%.
One building gives you one property type in one city, with no index to spread the risk. A flex building mixes offices and warehouse space under one roof, so its tenants come from two kinds of demand.
Industrial REITs returned 17.0% in 2025 and 5.3% from January to September 2026 (Nareit, industrial REIT returns). On September 30, 2026, they paid a dividend yield of 3.68%, against 4.63% for office REITs. A lower yield means investors paid more for each dollar of dividends, so the market already priced in much of industrial's strength.
Run three tests on any building: its yield against a government bond, its rent against the loan payments, and the price fall its down payment can absorb. The seller's offering memorandum supplies the rent roll and the NOI, so check them against the leases first.
Take a building priced at $3,000,000 with $195,000 of NOI. Its capitalization rate (cap rate), NOI divided by price, is 6.5%. The buyer borrows 65% of the price, $1,950,000, over 25 years. The interest rate of 6.88% is an assumption: the 10-year Treasury yield plus a spread of 1.75 points.
The 10-year Treasury averaged 5.13% in October 2026 (FRED, 10-year Treasury yield). Canada's 10-year benchmark bond averaged 3.87% that month (Bank of Canada, 10-year bond yield).
| Test | The example | Result |
|---|---|---|
| Yield over the US 10-year Treasury | 6.5% minus 5.13% | 1.37 points |
| Yield over Canada's 10-year bond | 6.5% minus 3.87% | 2.63 points |
| Debt service coverage ratio | $195,000 / $163,599 of yearly payments | 1.19 |
| Cash-on-cash return | $31,401 / $1,050,000 invested | 3.0% |
| Price fall that erases the down payment | $1,050,000 / $3,000,000 | 35% |
Read the results in order:
- The yield test asks what the building pays for its risk. A margin of 1.37 points over a bond with no tenants is thin. The same building in Canada clears its bond by 2.63 points.
- The debt test divides NOI by the loan payments, the debt service coverage ratio (DSCR). At 1.19, the building falls short of the 1.25 the pillar guide uses to show how a lender sizes a commercial loan. The lender would shrink the loan and ask for more cash.
- The cash test gives 3.0% a year on the money invested, under the Treasury yield.
- The downside test sets the 35% cushion against history. The Federal Reserve's commercial real estate price index fell 39% from the third quarter of 2007 to the fourth quarter of 2009 (FRED, commercial real estate price index). A fall that size would leave this building worth about $1,830,000, under the $1,887,071 still owed after two years of payments.
At $3,000,000, the building fails the debt, cash and downside tests. The same rent at a lower price passes more of them, which is why the price you pay decides the investment. The commercial mortgage calculator gives the payment at other rates and terms.
A good return beats the 10-year government bond yield by enough to pay for vacancy, repairs and the months a sale takes. Set your floor at that bond yield, then ask how wide the margin should be for the building's tenants and lease lengths. The example's cash return of 3.0% sits under its floor, so its price or its loan has to change.
In late 2026, listed REITs pay less income than a 10-year Treasury, US commercial property prices sit below their 2023 peak, and bank loans on commercial property are mostly current. Each of those facts cuts a different way for a buyer.
- Income. On September 30, 2026, the all-equity REIT index paid a dividend yield of 3.93% (Nareit, REIT dividend yield). The 10-year Treasury averaged 4.99% in September 2026 (FRED, 10-year Treasury yield). A REIT buyer at that yield counts on rent growth to make up the gap.
- Prices. In the second quarter of 2026, the Federal Reserve's price index stood 6% below its level of the second quarter of 2023 (FRED, recent commercial property prices). A buyer now pays less than a 2023 buyer did for the same index of buildings.
- Loans. Banks reported 1.53% of their commercial real estate loans as delinquent in the second quarter of 2026 (FRED, bank delinquency rate). The series starts at its highest point, 11.99% in the first quarter of 1991.
The lending guide explains how commercial real estate loans work, including the maturity date that forces an owner to refinance in a weak market.
Two beliefs mislead new investors: that commercial property always keeps pace with inflation, and that a higher cap rate makes a better deal.
The year you buy decides whether prices beat inflation. The table compares the Federal Reserve's commercial real estate price index with the consumer price index, from three starting quarters to the second quarter of 2026 (FRED, commercial property price history; FRED, consumer price index).
| Bought in | Commercial property prices | Consumer prices |
|---|---|---|
| The first quarter of 2000 | +151% | +96% |
| The third quarter of 2007, the peak | +25% | +60% |
| The fourth quarter of 2009, the low | +105% | +53% |
A buyer at the 2007 peak held a building whose price trailed inflation 19 years later. A buyer at the 2009 low doubled the price and beat inflation by a wide margin. The rent collected over those years comes on top of these price changes, because the index measures prices only.
A higher cap rate buys more income per dollar of price, and the market sets it higher for a reason. A high cap rate is how buyers price weaker tenants, shorter leases or flat rents, as the cap rate guide explains in whether a higher or lower cap rate is better. Compare cap rates only between buildings with similar tenants and lease lengths.
