The East Bay Guide to Tenancy in Common (TIC)

No — but the reputation has a real origin. Nearly every TIC horror story traces to how these deals used to be financed. In the old TIC 1.0 model, the entire building sat on a single shared mortgage — often an assumable jumbo — with every co-owner jointly liable. One owner's default could push the whole loan into delinquency, forcing the others to cover the entire payment; a non-paying co-owner was still an owner, not a tenant, so you couldn't simply evict them; and selling your share meant the other owners had to accept the buyer while the bank re-qualified them.

Those risks were real. They're also mostly gone. The modern TIC 2.0 structure — individual fractional loans, professionally drafted agreements, recorded documents — dismantles every one of them. A modern TIC isn't more complicated than a condo. In some ways it's simpler. The rules governing a TIC are simpler than the rules at your local pickleball court, and nobody's going to fault you for standing in the kitchen of your own home.

East Bay TICs typically sell at a discount of roughly 15–20% — but here's the wrinkle that makes the East Bay different from San Francisco: what you compare a TIC to depends on what it physically is. Many East Bay TICs aren't stacked flats; they're detached structures on a shared lot. A detached TIC lives like a house, so the honest comparison isn't a condo — it's a single-family home. That kind of TIC sells at roughly 15–20% below a comparable single-family home. The flat-style TICs, meanwhile, price against comparable condos. Either way the discount is similar; the benchmark shifts with the building.

That discount is structural, and here's the actual chain of cause and effect — none of it a defect in the home:

• TIC loans require more money down. That's the starting condition everything flows from.
• A larger down payment shrinks the buyer pool. Fewer buyers can clear that bar, which creates a real barrier to entry.
• A smaller pool means less competition. Fewer bidders on any given TIC means less of the bidding-war pressure that drives prices up.
• Less competition means a better entry price. The same barrier that screens other buyers out protects you from getting run up once you're in.
• Add the perception gap. Because TICs are less familiar, many buyers assume unfamiliar means risky and steer clear — deepening the discount for buyers who understand the structure.

You're not paying less because you're getting less. You're paying less because fewer people are standing next to you at the auction. And when the TIC is a detached structure, you're getting house-like living for 15–20% under what an actual house would cost.

This is the most important thing to understand about buying a TIC, and it's the dividing line between the old scary TICs and modern safe ones. A group (or blanket) loan is one mortgage covering the whole building, with every co-owner jointly on the hook — the TIC 1.0 structure that earned TICs their bad name. If one co-owner stopped paying, the entire loan went delinquent, and the others had to cover the whole payment while being unable to evict a non-paying owner.

A fractional (or individual) loan is the TIC 2.0 fix and today's East Bay standard. Each co-owner has their own separate mortgage, secured by their own fractional interest — your payment, your credit, your lender. Your co-owner's finances cannot touch yours. If they default, that's between them and their lender; your loan and your ownership stay insulated. When buying a TIC, confirming you're getting an individual loan rather than a group loan is the single most important question you'll ask. While traditional national lenders don't touch TICs, several well-established local banks actively service TIC loans across the Oakland, Berkeley, and greater Bay Area market — an agent who works in this space can hand you that lender list on day one.

TIC lenders require more down than a conventional condo buyer needs, and on its face that looks like a hurdle. Look closer and it's a feature. Federal housing-finance research is unambiguous: mortgage default and foreclosure rates rise steadily and accelerate as down payments shrink, so a buyer putting 3% down is meaningfully more likely to default than one putting 20% down. In a condo, your fellow HOA members may have bought with 3–5% down, no equity cushion, and a budget already stretched thin before the HOA dues land. In a well-structured TIC, every co-owner has six figures of their own money in the building and every incentive to protect it. The requirement people think of as a barrier quietly pre-screens your co-owners for financial stability — you're buying into a well-capitalized group, not a random draw.

Here's the East Bay's best-kept TIC secret: a meaningful share of local TICs aren't shared-wall units at all. Unlike San Francisco, where TICs are typically flats stacked in one building, many Oakland and Berkeley TICs are physically separate structures on a shared lot — your own detached building, your own entrance, your own yard, your own garage, no common walls with anyone. The legal structure is TIC; the lived experience is a single-family home. You get the privacy and feel of a house at roughly condo pricing, and these properties are consistently underpriced relative to what they deliver.
