The two ends of the East Bay market right now

I have been selling real estate in this area since 1978, and I have watched the entry point in the East Bay move further out of reach almost every year. What has not changed is how poorly the headline number on a listing explains what a buyer is actually getting.

This month I have two properties open on the same weekend that sit at opposite ends of the range. Put side by side, they explain the current market better than any median price ever will.

At $383,000: a condominium in San Ramon

Upgraded kitchen with stone countertops and lighted glass-front cabinetry, in-unit laundry, mirrored closet doors, level-in access with no steps at the entry, and an assigned carport.

What the buyer gets: a San Ramon address, a fixed and predictable exterior maintenance burden, and a price point that has become genuinely scarce in this city.

What the buyer does not get: land, control over the exterior, or freedom from a monthly assessment. The homeowners association covers water, sewer, insurance, exterior maintenance, grounds and gate security — real value, but a payment that exists whether or not the owner uses any of it.

At $999,950: a house in Castro Valley

Single-level ranch on a quiet court. Hardwood through most of the home, a custom tray ceiling and crown molding in the living room, a remodeled kitchen with solid-surface counters and a gas range, a dedicated laundry room, and a fenced backyard with a patio deck. No homeowners association.

What the buyer gets: the dirt. Every decision about the exterior, the yard, the roof and the detached structure belongs to the owner. There is no board, no assessment, and no shared wall.

What the buyer takes on: every one of those decisions becomes a cost the owner budgets for directly. A 1949 house with one bathroom is a different maintenance profile than a 1988 condominium with a management company.

Why price per square foot misleads almost every buyer

This is the part I end up explaining at nearly every open house, and it is worth putting in writing.

Price per square foot is a derived number. It is only as reliable as the square footage figure it was divided by — and that figure is entered by a person, drawn from records of varying age, and is not always measuring the same thing from one listing to the next.

A common example: when a property has a detached secondary structure, some listings report the combined interior area and some report only the main dwelling. Those two conventions produce meaningfully different price-per-square-foot numbers for the identical property. A buyer comparing two listings has no way to know which convention each one used.

What I tell buyers to do instead:

01  Ask what is included in the square footage

Main dwelling only, or main dwelling plus detached structures? Is a converted garage counted? Two listings can quote the same number and mean different things.

02  Ask whether conversions were permitted

Unpermitted square footage affects appraisal, financing, insurance, and what you are legally allowed to do with the space later. In Castro Valley those records sit with Alameda County, not a city hall.

03  Compare total monthly cost, not purchase price

Principal, interest, taxes, insurance and any association dues. Two homes $300,000 apart on price can be far closer than that on a monthly basis.

04  Value the lot separately from the structure

In the East Bay, land is frequently the larger share of the value. A smaller house on a better lot is often the stronger purchase.

The math most buyers skip: association dues versus ownership costs

Buyers comparing a condominium to a house usually treat association dues as pure extra cost. That is not quite right, and the mistake runs in both directions.

A monthly assessment covering water, sewer, insurance, exterior maintenance and grounds is paying for things a house owner also pays for — just unbundled, unpredictable, and often deferred until something fails. The honest comparison is not dues versus no dues. It is a fixed known number versus a variable unknown one.

Where the condominium buyer genuinely loses ground is control and appreciation profile. Where the house buyer genuinely loses ground is exposure to a single large repair arriving at a bad time.

Neither is the right answer for everyone. But a buyer who has run that comparison honestly makes a far better decision than one who anchored on the purchase price alone.

What this means if you are buying in the East Bay this year

• Under $400,000 is a narrow shelf, not a tier. In cities like San Ramon, properties at this price are a small fraction of active inventory. If that is your range, be ready to move when something appears rather than waiting for a selection to choose from.
• Around $1 million in Castro Valley does not automatically mean move-in perfect. It frequently means a well-kept older home on good land. Budget for the house you are buying, not the one in the photographs.
• Get the total monthly number before you fall in love with a listing. I would rather have that conversation with you in week one than week four.

Frequently asked questions

What is the cheapest type of home available in San Ramon right now?

One-bedroom condominiums in gated communities represent the lowest active price point in San Ramon, generally in the high $300,000s. Availability at this level is limited and changes week to week.

Is it better to buy a condo or a house in the East Bay?

It depends on how much control you want over the property and how you handle unpredictable costs. A condominium converts many ownership costs into a fixed monthly assessment. A house gives full control of the land and exterior but exposes the owner directly to repair costs as they arise.

Why do two listings with the same square footage show different prices per square foot?

Because square footage is not always measured the same way. Some listings include detached structures or converted spaces in the total; others report only the main dwelling. Always ask what is included in the figure before comparing.

Do homeowners association dues make a condo more expensive than a house?

Not necessarily. Association dues typically cover costs a house owner also pays — insurance, water, exterior maintenance, grounds — but as a fixed predictable amount rather than as irregular expenses. The meaningful comparison is total monthly cost of ownership, not purchase price.
