For most of the last decade, the buy-versus-lease question answered itself in the San Fernando Valley. Sale prices ran away from what the monthly math could justify, vacancy sat under 2%, and any owner-user who wanted a building competed with investors paying cash. Leasing won by default.
That has changed, and the headline numbers understate how much. CoStar data via Matthews puts the SFV’s average industrial value at $345/SF in Q2 2026, but that average is pulled up by newer, larger product. The buildings owner-users actually buy tell a different story: across 64 West Valley sales in 2025, the average closed price was $233/SF, on buildings averaging 16,408 SF and a 1973 build year. Meanwhile asking rents keep sliding, down 4.4% year over year across the SFV. When the product you’d buy trades roughly $100/SF below the market-wide average and rents are falling, the monthly comparison changes. For a business in the 10,000–30,000 SF range, buying and leasing now cost close to the same each month.
Close to the same is not the same as better. What follows is the actual arithmetic, and the specific conditions where each option wins.
At a Glance: 20,000 SF in the West Valley
| Lease | Buy (owner-user) | Note | |
|---|---|---|---|
| Up-front cash | 2–3 months security | $466,000 (10% down) | SBA 504 minimum |
| Monthly, before taxes | $29,000 base rent | ~$28,300 debt service | NNN costs sit on top of both |
| Rate exposure | Resets at renewal | 6.17% fixed, 25 years | CDC portion of a 504 |
| Property tax basis | Landlord’s, often decades old | Yours, reset at purchase price | Prop 13 |
| Exit | Walk at term | Sell, lease out, or refinance | Illiquid |

The buildings owner-users buy trade $100/SF below the market average
Start with the Q2 2026 SFV numbers. Vacancy sits at 5.9%, still the lowest of any LA submarket but a long way from the sub-2% of early 2022. Asking rents run around $1.63/SF NNN per month and are falling 4.4% year over year. Cap rates average 5.4%, and $228 million traded during the quarter.
Now set the market-wide $345/SF average value against what actually closed. Across 2025, roughly $191.7 million traded over 64 West Valley transactions at an average of $233/SF, with a median sale price of $3.25 million and an average building size of 16,408 SF. The average building that sold was built in 1973.
Read those together and a profile emerges: mid-size, older, functional product changing hands at prices a private business can actually finance, roughly $100/SF below the SFV-wide average that headline reports quote. That is the owner-user market. It is not institutional investors chasing new construction, and it explains why the $3M–$7M band has stayed the most active price range in the Valley through a softening cycle.
“The buyers we’re seeing in the Valley right now are operators, not funds,” says Ron Kassan, Executive Vice President at Available Warehouses. “They’re buying the building they already occupy, or one two miles away, because at these prices the note pencils against what they were paying in rent.”
Broader context matters here. Across Greater Los Angeles, Colliers reported net absorption of 7.7 million SF in Q2 2026, the strongest quarterly demand since Q4 2022, against a twelfth consecutive quarter of falling asking rents. Demand is returning while pricing power has not. That combination favors whoever is signing in 2026, on either side of the transaction.

What a 20,000 SF building actually costs each way
Take a 20,000 SF building in Chatsworth or Canoga Park, the size and submarket where most of this activity sits.
Leasing it. At the West Valley’s $1.45/SF NNN asking average (the SFV-wide figure runs higher, around $1.63), base rent runs $29,000 per month. On top of that you pay property taxes, insurance, and maintenance through the NNN structure. Up-front cash is a security deposit, typically two to three months. Your rate resets whenever the lease does.
Buying it. At the $233/SF that comparable West Valley product averaged across 2025’s closed sales, the building prices at $4.66 million, inside the $3M–$7M range where SBA 504 financing is designed to work. A 504 puts 10% down, so $466,000 of equity, and finances the remaining $4.19 million across two notes: a conventional bank first and a CDC second currently fixed at 6.17% for 25 years. Assume a blended rate around 6.5% across both and debt service lands near $28,300 per month.
So the monthly numbers cross. Owning runs a few hundred dollars a month below leasing, on a building you own outright in 25 years instead of renting for 25 years. The NNN costs are roughly a wash, since a triple-net tenant already pays taxes, insurance, and maintenance.
One caveat on that blended rate: the CDC half is fixed and published monthly, but the bank half is quoted deal by deal and depends on your credit, your operating history, and the lender. Run your own numbers with a lender before you treat the comparison as settled.

Prop 13 resets your tax basis the day you close
Here is the line item that surprises owner-users, and the one most buy-versus-lease calculators leave out.
California assesses property tax on the value at the time of transfer. As a tenant in a building that has been held by the same private owner since the 1990s, the taxes passed through to you under NNN are calculated on that owner’s decades-old basis. Buy the building and the assessment resets to your purchase price. On a $4.66 million purchase in Los Angeles County, that reset can add roughly $4,000–$5,000 per month in property tax that the previous tenant was not paying.
That does not kill the case for buying. It does mean the honest comparison is debt service plus a stepped-up tax bill against base rent plus a legacy tax bill. Given the average SFV building trading today was built in 1973, a lot of the inventory carries exactly this kind of long-held, low basis.
“I’ve watched buyers get to the closing table thrilled about the note and then open the first tax bill,” says Art Minassian, Senior Vice President at Available Warehouses. “Ask for the current assessed value early. It’s public, it takes ten minutes, and it changes the math.”

When leasing is still the right call
Buying is the wrong move for a real share of the businesses that ask us about it.
Lease if your headcount or throughput could swing 30% in either direction over the next three years. A building you own is an asset you have to sell or sublease to exit, and industrial buildings in the Valley do not trade quickly at the price you want. Lease if the $466,000 down payment does more for you inside the business, in equipment, inventory, or hiring, than it does locked in a slab. And lease if your operation depends on a specific configuration you have not found yet: 24-foot clears, a particular power service, yard depth for trailer parking. Committing capital to the wrong box is more expensive than renting the right one.
There is also a middle path worth naming. Some owner-users buy a building larger than they need, occupy 60% of it, and lease the balance. SBA 504 requires that you occupy at least 51% of an existing building, which leaves real room to carry part of the note with a tenant. We have seen that structure work well for businesses that expect to grow into the space over five to seven years.
What This Means for Owner-Users and Tenants
- Get your assessed value before you get emotional about a building. Pull the current assessment from the LA County Assessor and model the reset. It is the single most common gap in a buyer’s spreadsheet.
- Check whether you sit in the $3M–$7M band. That is where the Valley’s transaction volume and SBA 504 financing both concentrate, and where you will see the most inventory.
- Do not treat the 6.17% as your all-in rate. That is the CDC portion. Get the bank first-lien quote before you compare anything.
- If you are renewing in the next 18 months, price both paths at once. Renewal is the natural decision point, and the comparison takes about a week. Our guide to negotiating an industrial lease in the SFV covers the leasing half.
What This Means for Owners and Investors
- Owner-users are your most motivated buyer pool right now. They underwrite against rent they already pay, not against a cap rate, which means they can justify a price an investor will not.
- Building age is working against you on price. The average building sold in the West Valley was built in 1973, and functional obsolescence (clear height, power, loading) is what separates a $290/SF sale like 20640 Nordhoff from the $233/SF average.
- Vacancy at 5.9% means pricing to the market, not to 2022. Twelve straight quarters of declining asking rents across Greater LA is a trend, and pricing against it beats chasing 2022 comps.
