California rent would take 17 years to catch up to a mortgage payment. At this year's pace, Los Angeles would take 54

Renters in California's biggest metro areas pay about $3,840 a month less than a new homebuyer would, and at the pace rents have grown for the past 11 years, it would take about 17 years for rent to catch up, Jonathan Lansner, the business columnist for the Southern California News Group, calculated from Zillow data. The median rent across the six metros was $2,929 in September, against an estimated $6,770 monthly payment on a $929,600 home.

Lansner's payment assumes 10% down and the 6.9% average 30-year mortgage rate in September, plus 2.2 percentage points to cover property taxes, insurance, and the higher rate a small down payment brings. Nationally, the gap is smaller. The $1,932 median rent is $739 below a $2,670 payment on a $366,900 home, and at 4.6% annual rent growth, rent would match it in about seven years.

San Jose has the widest gap. Rent of $3,812 a month would need about 36 years at its 3% historical growth rate to reach an $11,180 payment on a $1.5 million home. In the Inland Empire, it's about nine years.

The last column swaps in each metro's most recent one-year rent growth from Zillow's September 16 report, which ran 1.6% in Los Angeles, 2.0% in San Diego, 1.7% in Sacramento, and 2.8% in Riverside, all below their long-run averages. At those rates, the gap in Los Angeles would take about 54 years to close, and in San Diego about 42.

The Bay Area runs the other way. Zillow had metro rent up 10.8% in a year in San Francisco and 7.6% in San Jose, which would close the gap in about 8.5 and 15 years. The city of San Francisco itself is moving faster still. Its typical rent is up 25.1% in a year, to $4,682 in August 2026, according to RentDataNow data, and it's up 6.6% in San Jose, to $3,563. In Los Angeles, typical rent is $2,778, up 0.8%.

Zillow's own math reaches the same place with different assumptions. Using 10% down, a 6.67% rate, and estimated taxes and insurance, it found typical rent below the typical new buyer's monthly payment in all 50 of the largest US metros. Nationally, renting saves $1,066 a month, or $12,792 a year, and investing that difference would earn about $322 in the first year at the 10-year Treasury yield, Zillow said. "The idea that renting is a consolation prize is outdated," said Mischa Fisher, Zillow's chief economist.

None of this counts what a buyer gets back. Owners build equity and lock in a payment that doesn't rise with the market, while a renter's check keeps climbing, which is the point Lansner's catch-up math is built to test.
