How Do I Buy or Sell Industrial or Warehouse Property in San Diego County?
In San Diego County, industrial is the most lender-favored commercial asset class, with tight supply near the border and port keeping quality product's cap rates low (roughly 5 to 6.25%). Big-box logistics softened statewide, but San Diego's infill, small-bay, and specialized space (life-science-adjacent, manufacturing) hold up. Value turns on the specs: clear height, dock doors, power, truck parking, and any yard. Serve First underwrites and brokers; Ashlar Lending arranges financing, including SBA 504 for owner-users; Ashlar LDA prepares the entity.

How a San Diego County industrial deal actually works
Industrial is bought on its physical capability and its location relative to demand. Here's how the pieces fit, with Serve First on the underwriting, Ashlar Lending on the financing, and Ashlar LDA on the entity:
Start with the building's specs
Industrial value begins with the 'spec stack': clear height, number and type of dock doors, column spacing, floor load, electrical service, and truck/trailer parking. These decide which tenants can use the building and what rent it commands. A modern distribution building and an older small-bay warehouse are different products, Serve First underwrites the specs, not just the price per square foot.
Know the San Diego County landscape
San Diego County blends border-trade logistics with a strong small-bay and specialized-manufacturing base. Big-box has softened, but infill and owner-user product near the urban core and border crossings stays in demand. Serve First helps you target the resilient segment.
If you'll occupy it, SBA 504 is powerful
For a business buying its own warehouse or manufacturing facility, SBA 504 financing is one of the best tools in commercial real estate: up to 90% financing with a low fixed rate on the SBA portion (around 5 to 5.5% for a 25-year term in 2026). It's built for owner-users occupying their building. Ashlar Lending can tell you quickly whether your plan qualifies, it can dramatically reduce the down payment on your own facility.
For investors, match the strategy to the loan
Stabilized, leased warehouse suits conventional or agency-style commercial financing; value-add plays, vacancy, below-market leases, deferred maintenance, suit bridge loans (roughly 7.75 to 9% in 2026, 12 to 36 months) that fund the repositioning; ground-up or build-to-suit suits construction financing. Ashlar Lending structures the leverage to your business plan.
Don't overlook the yard (IOS)
Industrial outdoor storage, usable, fenced yard for trucks, containers, or equipment, has become one of the most valuable and supply-constrained industrial niches, because California cities increasingly restrict new yards. A property's yard can trade at a different value than the building itself. Serve First flags IOS value others miss; Ashlar LDA can prepare the entity and deeds at your direction.
Underwrite the specs and the submarket, not just the cap rate. Two San Diego County warehouses at the same price can perform very differently: low clear height, too few dock doors, or weak power can shrink the tenant pool and the rent, while a scarce infill location or a usable outdoor yard can add value the headline number misses. And in a normalizing market, big-box and smaller-bay product are moving in different directions. Serve First underwrites the building and its submarket so you buy on reality.
One family. Deal, financing, and entity.
Buy or sell the warehouse, from an investor’s or owner-user’s seat
Industrial is the property type lenders favor most, and the financing reflects it. The Ashlar Brands family works the whole deal:
- Serve First Realty sources and underwrites industrial property on the specs that actually drive value: clear height, dock doors, power, trailer parking, and any usable outdoor storage yard, and represents you buying or selling.
- Ashlar Lending Inc. (NMLS #2699657) matches the deal to the right program: SBA 504 for a business buying its own warehouse (up to 90% financing at low fixed rates), plus conventional, bridge (for value-add), and construction financing.
- Ashlar LDA, Inc., a bonded and registered Legal Document Assistant, can prepare the LLC or entity paperwork and deeds at your direction.
These are separate businesses in the Ashlar Brands family. Serve First is a real estate brokerage, not a lender or law firm; loan terms and SBA occupancy rules are set by the lender and SBA. A Legal Document Assistant prepares documents at your direction and is not a substitute for an attorney. This is general information, not tax advice.

Frequently asked questions
Why is industrial considered a strong asset class?
Because it underpins e-commerce, logistics, and local trades, and lenders consistently favor it. Even as the market normalized from its pandemic-era peak in 2026, industrial remained the most-favored commercial property type for financing. The nuance is that big-box logistics softened with new supply, while smaller-bay and infill space near population centers stayed tight, so segment and location matter.
What determines an industrial building's value?
Its physical specs and location more than anything. Clear height, dock-door count and configuration, column spacing, floor load, electrical service, and truck/trailer parking determine which tenants can occupy it and what rent it earns. Location relative to ports, highways, and population centers drives demand. A usable outdoor storage yard can add significant value. Serve First underwrites all of this, not just price per square foot.
Can I use an SBA loan to buy my own warehouse?
Yes, and it's often the best option. SBA 504 loans finance owner-occupied industrial property with up to 90% financing and a low fixed rate on the SBA portion (around 5 to 5.5% for 25 years in 2026), which dramatically lowers the down payment versus conventional financing. The requirement is that your business occupies the building. Ashlar Lending can confirm whether your purchase qualifies.
What is industrial outdoor storage (IOS)?
It's usable, typically fenced outdoor land for parking trucks, storing containers, or staging equipment, often alongside or instead of a building. IOS has become one of the most supply-constrained, valuable industrial niches because California cities increasingly restrict new yards, so existing yards are scarce. A property's yard can be worth as much as its structure. Serve First helps identify and value IOS that others overlook.
Is now a good time to buy industrial in California?
It depends on the segment. After years of rapid growth, the market normalized in 2026, big-box logistics vacancy rose as new supply was absorbed, creating selective entry points, while small-bay and infill product stayed tight. For owner-users, low SBA rates make buying your own facility attractive; for investors, value-add infill and second-generation warehouse with below-market rents are the focus. Serve First helps you weigh the specific opportunity.
