Why an apartment building
How it differs from buying a house to rent out — and what the numbers look like in this market right now.
For most people considering their first income property, the picture that comes to mind is a house. Buy one, rent it out, wait.
The problem shows up on the monthly statement. Even rented, a house often takes money out of your pocket every month. Principal and interest, property tax, insurance, and repairs frequently add up to more than the rent. That is a bet on the price going up, not an asset that runs on its income.
An apartment building works differently.
The building runs on its own income
A house has one tenant. When that tenant leaves, income goes to zero.
An apartment building has several units. One vacancy does not stop the rest. And the price is set on what the building earns — net operating income capitalized at a market rate — rather than on what the house down the street sold for.
Bought at the right price, the building covers debt service and operating costs and leaves something behind. The money you were feeding into a single-family rental every month runs the other direction.
That structure does not survive a bad purchase price. It also does not survive taking the seller's numbers at face value. This is why due diligence on the rent roll and two to three years of actual operating statements is the substance of the deal, not a formality.
A lower-volatility real asset
Most older Los Angeles apartment buildings sit under the city's Rent Stabilization Ordinance, which caps how much rent can rise in a year.
That is a real constraint. It has also restrained speculative overheating in price. Upside and downside get compressed together, and this is why the asset class has been regarded as a lower-volatility real asset.
There is a second effect. A tenant paying below-market rent has little reason to move, because moving means paying full market rent somewhere else. Turnover runs slow, and vacancy has tended to stay below newly built product.
Pricing has come back to roughly where it was a decade ago
This is likely why you are looking at the market now.
That is not a published statistic. It is what Total Commercial observes brokering older apartment buildings around greater Los Angeles. New construction is excluded from those figures.
Published market data reads lower. The average cap rate reported for greater Los Angeles multifamily is 5.8%. The gap is a matter of what gets counted: those averages fold in newly built Class A product and a far wider geography. New construction prices high and caps low, which pulls the average down.
The direction agrees. That same average is up from 5.5% a year earlier. A higher cap rate means paying less for the same income.
The price decline shows up in the published numbers too. Average price per unit is down roughly a quarter from the 2022 peak, and fell 12.9% in the second quarter of 2026 alone, to $285,504.
Transactions are moving. Multifamily deal flow across the Los Angeles metro rose 25% over the past year, with private investors accounting for 66% of volume.

The other side of it
Prices came down for reasons. Those reasons have not gone away.
Interest rates are the largest of them
When borrowing costs rise, the same rent supports a smaller loan, and a buyer can pay less. Much of the cap rate expansion and price decline above traces back to this.
It cuts both ways. You buy at the lower price, but you also carry the higher rate that produced it. The financing terms at acquisition are the single largest variable in the return. Find out what you can borrow and on what terms before you start choosing buildings.
If rates come down, the force runs the other way. We have no idea when or whether that happens, and it should not be an assumption in your underwriting.
Regulation is tightening, not loosening
In December 2025 the Los Angeles City Council reduced the RSO increase formula. The floor went from 3% to 1% and the ceiling from 8% to 4%. “You can raise at least 3% a year” is no longer true. (LAHD · AAGLA)
Operating costs are outrunning income
We are in the operating statements and income detail of properties coming to market constantly. The increases we see in those numbers run ahead of what gets quoted in industry summaries.
Insurance most of all. Wildfire exposure and carriers withdrawing from California have pushed premiums up at each renewal, and in some cases the same premium now buys less coverage because deductibles have risen. Utilities, materials, and labor move the same direction.
Rental income is capped by regulation. Expenses are not. That gap is the most concrete risk in this asset class. It is also why the seller's expense figures should be checked against two to three years of actual statements rather than accepted.
Rents are flat
Average asking rent across Los Angeles rose 0.2% year over year, and vacancy is 5.5%, up from 5.0% a year earlier. That vacancy figure covers all inventory including new construction; the increase is concentrated in newly delivered high-end product where new supply is landing. (Kidder Mathews, Q2 2026)
Measure ULA belongs in the math
Above a $5.4M sale price, the city transfer tax applies to the entire price rather than the amount above the threshold. That is a question for the eventual sale rather than the purchase, but it should be understood going in.
Where that leaves it
Pricing is back near decade-ago levels and yields have risen. What produced that pricing is higher rates, and regulation and operating costs have both gotten worse.
All of that is true at once. Read only the price decline and this looks like an opening; read only the regulation and expenses and it looks like a market to avoid.
The answer is specific to the building. Two properties on the same street at the same price can be entirely different assets depending on tenant tenure and where in-place rents sit against market. A building full of long-term tenants carries embedded upside that a fully repositioned one does not.
