Part of it reflects the national rent run-up of 2021 and 2022, and some of it can fade when new buildings open nearby, so we don't project the same pace forward.

Rental vacancy is 5.1%, within the normal range for a balanced market. 45% of renters spend 30% or more of their income on housing. That is close to the national picture, where roughly half of renters do, so rent increases need to track local wage growth.

Santa Clara County Rent Affordability In Dollars

The median rent in Santa Clara County works out to $34,284 a year, about 20.9% of the median household income of $164,281. Under the common 30% guideline, a household needs about $114,300 a year to cover that rent comfortably. That's a lighter load than the California average 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.

Since the 2015–2019 survey, the median rent rose $589 a month ($7,068 a year), while median household income rose $40,202 a year. Income has outpaced rent, which means tenants have a bit more room in their budgets than they did five years ago. HUD's FY2027 Fair Market Rent for a two-bedroom unit, $3,272, is 14.5% 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 Santa Clara County

Our buy box in Santa Clara County is the same one we use nationwide: 5+ unit apartment buildings, stabilized or in need of work, priced on today's rents. Then we test the property against the local data on this page and a full inspection of its major systems.

Property taxes are a big line item for any California apartment building. We underwrite the tax bill after purchase, not the seller's current bill, since a sale often resets the assessment. 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.

Given how fast rents rose here, we assume much slower rent growth going forward and make sure the deal still works if rents stay flat for a while.

Due Diligence For Apartment Syndications In Santa Clara County

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

• What vacancy does the plan assume? Rental vacancy in Santa Clara County is 5.1%. A plan that assumes much lower vacancy than the market should explain why.
• What rent growth is underwritten? Rents here rose 26% 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 Santa Clara County was built in 1975, 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 A Santa Clara County Apartment Syndication Works

Here's the short version. The general partner, in this case Skyline, finds an apartment building in Santa Clara County, buys it with a loan and investor capital, and runs it.
