Quick Answer: San Antonio Class B and C multifamily is working through the back end of a supply correction. Effective rents fell 5.4% year over year to $1,157 in Q2 2026 and occupancy sat at 86.0%. Deliveries drop to roughly 3,364 units this year against forecast absorption of 4,424, which flips the supply-demand balance for the first time since 2021.
What Is San Antonio Class B and C Multifamily?
San Antonio Class B and C multifamily refers to the metro’s older, non-luxury apartment stock: Class B properties generally built between 1980 and 2005, and Class C properties built before 1980. These communities house the region’s workforce at rents well below new construction, and they make up most of the metro’s tradeable inventory.
Serving the San Antonio-New Braunfels MSA, this older stock is what actually absorbs the region’s growth. San Antonio added 23,945 residents between July 2023 and July 2024, the fourth-largest numeric gain of any U.S. city, according to the U.S. Census Bureau. Very few of those households are signing leases at Class A pricing.
Class B vs class C: where the line actually sits
Age alone doesn’t set the grade. Location, mechanical systems, and resident credit quality do more of the work. A 1998 garden community on the Far Northwest side with a 2015 roof underwrites nothing like a 1972 East Side walk-up carrying deferred plumbing and double-digit delinquency. The label follows the cash flow.
| Factor | Class B multifamily | Class C multifamily |
|---|---|---|
| Typical build era | 1980 to 2005 | Before 1980 |
| Resident profile | Working households, some renters by choice | Workforce and cost-constrained renters |
| CapEx focus | Interiors, amenities, curb appeal | Roofs, plumbing, electrical, HVAC |
| Debt availability | Agency and bank debt widely available | Tighter terms, more bridge and local bank |
| Dominant risk | Rent competition from new supply | Expense inflation and delinquency |
How Are San Antonio Class B and C Apartments Performing in 2026?
Metro-wide effective rents averaged $1,157 in the second quarter of 2026, down 5.4% year over year, with occupancy at 86.0% after a 210-basis-point annual decline. Trailing four-quarter absorption of 3,497 units still trailed 6,284 units delivered, though quarterly absorption more than doubled from 673 units in Q1 to 1,747 in Q2.
The concession gap most market reports skip
Here’s a number worth pulling apart. Yardi Matrix put average asking rent at $1,232 through March 2026, while effective rent tracked closer to $1,157. That spread of roughly $75 a month is concession burn, about 6% of gross rent, and it’s the single largest drag on owner revenue right now.
Concessions don’t show up in an asking-rent headline. They show up in your trailing twelve months.
Why class B multifamily is holding better than the headline suggests
The two most-cited datasets disagree, and the disagreement is informative. Yardi reports 89.8% occupancy across stabilized assets, while all-property tracking shows 86.0%. That roughly 380-basis-point gap sits almost entirely in lease-ups, which means stabilized Class B and C properties are running materially tighter than the metro average implies.
That’s the case for workforce housing in a soft year. New deliveries compete on concessions and amenity packages. Older assets compete on absolute rent, and absolute rent is what a household earning near the area median can actually pay. HUD publishes the FY 2026 income limits that define that band for the San Antonio-New Braunfels MSA.
What Should Owners Expect From Cap Rates and NOI Growth?
The average cap rate multifamily buyers are underwriting in San Antonio has held between 6.0% and 6.5% since early 2024. Median price per unit ran $129,300 in the first half of 2025, down from $135,200 in 2024. First-quarter 2026 trades cleared $142,705 per unit on $96 million of volume, a 20% year-to-date increase.
That per-unit figure still sits well below the $196,464 national average, which is exactly why out-of-state capital keeps circling the market.
Where multifamily NOI growth actually comes from this year
Not from rent. With effective rents forecast to finish 2026 at $1,221, up 0.2% from $1,219, the revenue line is roughly flat. Every point of multifamily NOI growth this year has to be argued out of the expense side and out of collections.
Insurance is the pressure point. A Federal Reserve Bank of Minneapolis survey of multifamily owners found premiums roughly doubled between 2021 and 2024, with one operator reporting insurance climbing from 6% of total operating expenses to a forecast 14%. Older Class C assets with aging roofs carry the worst of that repricing.
Delinquency is the other lever, and it’s the one most owners under-manage. A 200-unit Class C property running 9% bad debt instead of 4% is giving back roughly the same dollars a full renovation program would generate. Tightening collections and delinquency management costs nothing in capital and shows up in the next month’s owner reporting.
Value add multifamily math when concessions are still live
Run the renovation premium against the concession spread before you commit capital. If the market is giving back $75 a month in effective rent and your classic-to-renovated premium underwrites at $110, the real captured premium is $35 until concessions burn off. That changes the payback period on a $6,000 interior scope considerably.
Value add multifamily still works in San Antonio. It just needs a longer hold assumption than 2021 underwriting used, and a capital projects plan sequenced to when concessions actually clear.
What multifamily investment underwriting should assume for the next 24 months
Supply is the story, and supply is collapsing. Only 3,768 units are under construction, equal to 1.6% of inventory, against a ten-year average of 6,772 annual completions. Northmarq expects completions to fall 21% annually and projects the first yearly vacancy decline since 2021.
One caution on pipeline numbers. Yardi Matrix counts 11,955 units “underway” in the metro, which reads alarming next to 3,768 units physically under construction. The difference is planned and permitted product that may never break ground at current debt costs. Statewide, Texas is on track for fewer than 35,000 deliveries in 2026, roughly 1.4% inventory growth, per the Texas Real Estate Research Center. Check which definition a broker is quoting you.
Demand, meanwhile, is fine but not heroic. The San Antonio-New Braunfels MSA carried a 4.8% unemployment rate in June 2026 with nonfarm employment up 0.6% over twelve months, per the U.S. Bureau of Labor Statistics. So the 2026 recovery in San Antonio Class B and C multifamily is supply-led, not demand-led. Underwrite it that way. If job growth reaccelerates, that’s upside you didn’t pay for.
Frequently Asked Questions
1. Is San Antonio a good market for multifamily investing in 2026?
San Antonio offers entry pricing at $142,705 per unit versus a $196,464 national average, cap rates of 6.0% to 6.5%, and a construction pipeline down to 1.6% of inventory. Rent growth is essentially flat this year, so returns depend on expense control and buying below replacement cost.
2. What is the average cap rate for multifamily in San Antonio right now?
The average cap rate multifamily buyers underwrite in San Antonio has held between 6.0% and 6.5% since early 2024, per Northmarq. Class C assets typically price above that band and Class A below it. Wide bid-ask spreads persist on deals with heavy deferred maintenance or high delinquency.
3. How does class C multifamily differ from class B for an owner?
The operating burden is different in kind, not just degree:
- Class C capital goes to systems and building envelope; Class B capital goes to interiors and amenities
- Class C carries higher delinquency and turnover, requiring tighter collections discipline
- Class B usually qualifies for agency debt; Class C financing is often bank or bridge
- Class C rents move less in a downturn, which cuts both risk and upside
4. Why are apartment rents in San Antonio falling?
Supply, not demand. The metro delivered 6,284 units over the trailing four quarters while absorbing 3,497, and that overhang pushed effective rents down 5.4% to $1,157. Asking rents fell 2.8% year over year while the national figure rose 0.1%, so this is a local supply story.
5. How much does a Class C apartment property cost per unit in San Antonio?
Metro median pricing ran $129,300 per unit in the first half of 2025, down from $135,200 in 2024. First-quarter 2026 trades averaged $142,705 across all classes. Class C generally clears below those metro figures and Class A above, with condition and delinquency driving most of the spread.
Conclusion
The correction in San Antonio Class B and C multifamily is nearly finished on the supply side and not yet finished on the revenue side. Rents flatten before they rise, concessions clear before pricing power returns, and 2026 is the year the pipeline finally stops fighting you. Owners who spend this window on expense discipline, collections, and sequenced capital will hold assets worth more when San Antonio’s rent recovery shows up in 2027. AAM Living manages market-rate apartment communities across the metro with that exact focus.
