A buyer touring a two-bedroom unit at Marina Point last month found the number on the flyer encouraging. Well under a million dollars for a lagoon-adjacent home in a city where waterfront properties routinely clear two million. Then came the HOA disclosure packet: monthly dues, a reserve study, and a notice about pending balcony inspections required under California's SB 326 law for buildings with elevated walkways. The number on the flyer was real. It just wasn't the whole story.
That gap between the sticker price and the full cost of ownership is not a fluke of one listing. It is the structural fact of buying in Foster City, and it explains something that trips up almost every buyer comparing this city to its Mid-Peninsula neighbors on median price alone.
Why Foster City Doesn't Have One Housing Market
Most Peninsula cities sell you a fairly consistent product. A median price in Belmont or San Mateo Park is mostly describing single-family homes on similar-sized lots, because that is most of what those cities are built from.
Foster City is different. The city was largely built out as planned-unit condominium and townhome development, which means detached single-family homes are the minority of the housing stock rather than the default. Marina Point itself is a 364-unit condo and townhome HOA built in 1976, sitting along Beach Park Boulevard with direct lagoon access. It is one of the oldest and largest communities in the city, and it is a completely different product from the detached homes fronting the water in Bay Vista or Shell Cove.
That single fact, that Foster City is mostly attached PUD product wrapped around a smaller core of detached single-family homes, is the reason a headline median tells you almost nothing about what you would actually pay.
Two Medians, Same Zip Code
Here is the gap in practice. Single-family sales in Foster City closed at a median of $2,122,500 in July 2026, across just eight transactions, according to MLS-reported county sales data. That is roughly in line with the full 2025 calendar year, when 103 single-family homes sold at a median of $2,200,000. Both numbers describe a small, waterfront-skewed slice of the market: single-family sales here rarely top a hundred a year.
Compare that to a snapshot of active listings across the whole city in early September 2026, which showed a median list price closer to $1,288,000 across all property types, with an average price per square foot around $885. That is not a contradiction. It is two different products showing up in two different measurements. One number is almost entirely single-family and waterfront-weighted. The other blends in the condos and townhomes that make up most of the city's inventory, Marina Point included.
If you are comparing "Foster City" to "Belmont" on a portal's median price, you may be comparing a blend of condos and detached homes against a market that is almost entirely detached homes. That is not a location comparison. It is a product comparison wearing a location's name.
What Each Sub-Market Actually Buys
The three tiers inside Foster City behave differently enough that treating them as one market obscures more than it reveals.
| Sub-market | What it is | Typical days on market | Cost structure |
|---|---|---|---|
| Marina Point and similar inland PUDs | Condos and townhomes, several built in the 1970s | Slower, often 50 to 60 days | Monthly HOA dues commonly $400 to $900, plus reserve and special assessment exposure |
| Bay Vista and Shell Cove | Detached single-family, direct lagoon access | Faster, often 30 to 40 days | No HOA on many parcels, but subject to the city's Waterfront Setback Policy governing docks, fences, and view protection |
| Inland single-family | Detached homes off the water | Moderate, tracking closer to the citywide average | Fewer PUD dues, but still limited supply since most of the city was master-planned around attached product |
The waterfront tier is not just pricier. It operates under its own evolving rulebook. The city is currently developing new Objective Design and Development Standards specifically for lagoon-front properties, covering setbacks, lot coverage, and dock rules, and is surveying waterfront homeowners as part of that process. A buyer or seller on the water in 2026 is dealing with a regulatory environment that inland Foster City owners simply are not.
The Closing Cost Nobody Mentions Until Escrow
There is one place where Foster City's structure actually works in a seller's favor. Because Foster City is a general law city rather than a charter city, its documentary transfer tax runs at the state minimum, $1.10 per $1,000 of the sale price, split evenly between the city and San Mateo County. In August 2025, the city council considered and declined to pursue a November 2026 ballot measure that would have moved Foster City toward charter status and added city-level transfer taxes. That decision keeps closing costs on the low end relative to Bay Area cities that have adopted their own transfer tax tiers.
That lower baseline does not offset what a PUD buyer pays in monthly dues over years of ownership, but it does mean net proceeds calculations for Foster City sellers start from a friendlier place than in cities where transfer tax has climbed.
What This Means If You're Comparing Neighborhoods
For a buyer weighing Foster City against a single-family-dominant neighbor, the useful question is not "what's the median price in each city." It is "which Foster City am I actually pricing." A Marina Point unit and a Bay Vista home sitting three-quarters of a mile apart can differ by well over a million dollars and carry entirely different monthly obligations once HOA dues and assessment history are factored in.
For a seller in an older PUD building, the SB 326 balcony inspection requirement and any pending special assessments are disclosure items worth resolving before a listing goes live, not after an offer arrives and a buyer's lender starts asking questions. For a seller on the water, the Waterfront Setback Policy and any recorded view-protection restrictions belong in the disclosure package from day one.
None of this makes Foster City harder to buy or sell into than its neighbors. It makes it a city where the number on the portal is doing the work of three different markets at once, and where asking which one you are actually looking at is the difference between an accurate comparison and a surprising escrow.
A Few Direct Questions
Are HOA dues in Foster City higher than nearby cities? Not necessarily higher across the board, but they are more common, since a larger share of the city's housing stock is attached PUD product. Dues in the $400 to $900 monthly range are typical for that product type here.
Why do some Foster City listings sell in half the time of others? Location relative to the lagoon is the biggest driver. Waterfront homes in areas like Bay Vista and Shell Cove have been moving in roughly 30 to 40 days, while inland PUD product, Marina Point included, has run closer to 50 to 60 days.
Does the low transfer tax make up for HOA costs? No, they are separate line items. The transfer tax affects what a seller nets at closing. HOA dues affect a buyer's monthly qualification math for as long as they own the property. Both matter, but for different sides of the same transaction.
