Hospitals, Chapman And Orange's Renter Base

Orange is a high-income city where more than four in ten households rent. It has 19,609 renter households, 43.3% of the total, close to California's 44.1%, and that count rose 8.1% in five years even as population dipped 1.2% to 138,266 (U.S. Census ACS 2020–2024). Median gross rent in Orange is $2,327 a month, up 28.8% from $1,806 in the 2015–2019 survey. Median household income is $117,113, up 27.6%, so rent and pay have moved almost together, though 53.5% of renters still spend 30% or more of income on housing.

Health care is the city's signature employer. The Orange County Business Journal called Orange a hospital city in 2007, when four hospitals sat inside it: UC Irvine Medical Center, St. Joseph Hospital, Children's Hospital of Orange County and Chapman Medical Center. Back in 2007 those four employed more than 9,700 people, before counting the medical offices around them. CHOC merged with San Diego's Rady Children's on Dec. 31, 2024, forming Rady Children's Health, which counts CHOC Hospital in Orange among its hospitals.

Chapman University is the other anchor. Its July 2025 economic impact report counted about 10,000 students in 2023 across its Orange and Irvine campuses, 2,240 faculty and staff, and 5,070 jobs supported in the city. Almost 30% of its employees live in Orange, and the university converted the Panther Village hotel into a residence hall. For apartment owners, the combination of nurses, medical staff, graduate students and university workers gives Orange a renter base that doesn't swing much with the business cycle.

Limited New Supply In Orange

Orange has 9,723 homes in buildings with five or more units, 20.7% of its housing, and that count grew just 1.8% in five years (U.S. Census ACS 2020–2024). The median home was built in 1973, so most apartments are older garden-style and low-rise buildings. Orange has seen far less new construction than its neighbors. Of roughly 4,000 apartments slated to open across Orange County in 2025 and 2,900 in 2026, about two-thirds were in Irvine and Santa Ana, the Orange County Business Journal reported in January 2025, citing Marcus & Millichap.

The newer projects in Orange cluster on the west side. AMLI Uptown Orange, a 334-unit community at 385 S. Manchester Ave., opened in 2016. Greenlaw Partners filed early plans in 2016 for three complexes totaling 821 units around the Outlets of Orange, and Bascom Group and Branch West bought a site at 1725 W. Katella in 2019 for a 94-unit, five-story building near the Honda Center. Elsewhere, infill tends toward for-sale housing: in May 2026 the city approved 71 small-lot homes on a 4.23-acre commercial site at North Tustin Street and East Helm Avenue.

That thin pipeline shows up in the numbers. The Census rental vacancy rate is 3.7%, and it covers rented houses and condos as well as apartments. The HUD fiscal 2027 two-bedroom fair market rent for the Santa Ana-Anaheim-Irvine area is $3,057, well above Orange's $2,327 median, which reflects how much of the city's stock is older and smaller. For apartment syndications in Orange, the opportunity tends to sit in those 1960s and 1970s buildings, where a buyer can plan renovations against limited new competition, as long as the underwriting accounts for California's tenant protection rules.

How Orange Ranks For Apartment Investors

Among the 276 California cities we track, Orange ranks 97th for median gross rent, 112th for renter share and 196th for five-year rent growth. Its rents fall in the middle of the pack. Put in counts rather than percentages, that is roughly 1,621 fewer residents, 1,469 more renter households and 172 more homes in buildings with 5 or more units than five years earlier. Renter households grew by about 8.5 for every new home in a larger apartment building. Not every renter lives in an apartment, but demand has clearly kept ahead of new multifamily supply.

Orange And Nearby Markets Side By Side

Orange's median gross rent of $2,327 is above the California median of $2,036, and its renter share is 43.3% compared with 44.1% statewide.

Rent Versus Income In Orange

At $2,327 a month, the median Orange rent adds up to $27,924 a year, or roughly 23.8% of what the median household earns. Under the common 30% guideline, a household needs about $93,100 a year to cover that rent comfortably. That's close to the California figure of 24.6%. Renters usually earn less than the all-household median, so the real burden for tenants is higher than this simple ratio shows.

In dollars, Orange rent climbed $521 a month over five years and household income climbed $25,332 a year. The two have moved together, so affordability today looks much like it did five years ago. HUD's FY2027 Fair Market Rent for a two-bedroom unit, $3,057, is 31.4% above the median gross rent for all unit sizes. That gap matters for buildings that accept Housing Choice Vouchers, since local housing authorities base voucher payment standards on it.

What We Look For In An Orange Apartment Building

We look at buildings with 5 or more units in Orange, from small walk-ups to larger garden-style communities, in stabilized or value-add condition. We compare in-place rents with nearby buildings, inspect roofs, plumbing and HVAC, and ask whether better management or targeted renovation can close the gap with the market.

Property taxes are a big line item for any California apartment building. We estimate the tax bill as it will be after the purchase, because a sale can trigger a reassessment in many places. California caps annual rent increases on most apartments older than 15 years under the Tenant Protection Act (AB 1482), and cities such as Los Angeles, San Francisco and Oakland have stricter local rent control. Our rent-control guides explain how these rules work. Insurance quotes in California reflect wildfire risk, so we get a quote before we make an offer.

After a stretch of fast rent growth, we keep rent assumptions modest and leave room for concessions if new supply opens nearby.

Due Diligence For Apartment Syndications In Orange

Whoever the sponsor is, these are the questions we would want answered about any apartment syndication in Orange, based on the local numbers above.

• What vacancy does the plan assume? Rental vacancy in Orange is 3.7%. A plan that assumes much lower vacancy than the market should explain why.
• What rent growth is underwritten? Rents here rose 28.8% over five years. Ask whether the plan assumes that pace continues, and what happens to the deal if rents stay flat.
• How was the property tax bill estimated? A sale often triggers a reassessment, so the bill after purchase can be well above what the seller pays today.
• What capital work is budgeted? The median home in Orange was built in 1973, so roofs, plumbing and electrical systems deserve their own line items.
• How and when does capital come back? Ask what the plan is for a refinance or sale, and what happens if that takes longer than expected.

How Passive Investing In An Orange Apartment Syndication Works

Two groups make an apartment syndication work. The sponsor, or general partner, handles the deal: finding the building, financing it and running the business plan. The limited partners are passive investors who contribute capital and share in the property's results under the offering's terms.

It's a long-term commitment. The property has to be refinanced or sold before most capital comes back, and the outcome isn't certain. Eligibility rules vary by offering, and most are limited to accredited investors. See investing with Skyline Capital for how we work with limited partners.
