What a condo costs in Silicon Valley
Redfin's median sale price for a Santa Clara County condo was $667,393 in September 2026, on 152 sales. That is 12.1% lower than in September 2025, when it was $759,000. Townhouses, which Redfin counts separately, had a median of $1,158,024, down 9.5%, and single-family homes $1,868,636, down 4.3%. A condo is the only way to buy in much of the valley for under $1 million.
Condos also sell on different terms from houses here. In September 2026 the county condo median took 46 days to sell, against 15 for a detached house, and sold at 99.3% of list price on average, against 103.3%. Only 23.9% of condos sold above list. There were 548 condos for sale, a 3.6-month supply. For a buyer that means room to negotiate, ask for repairs and take time over the HOA documents. For a seller it means pricing carefully from the first day.

Is it wise to buy a condo in Silicon Valley now?
The case for buying is price. Condos are the part of the valley market that has fallen most: the county condo median was down 12.1% in a year to September 2026, while detached houses were down 4.3%. Buyers have more listings to choose from and more time to decide.
The case for caution is cost of ownership. California requires associations to inspect balconies, decks and other exterior elevated elements on a schedule, and to keep reserve studies current; a building that has deferred this work may face a special assessment. Read our balcony inspection law guide and our California HOA laws guide before you write an offer. Insurance is the other risk: ask how the master policy is placed and what it costs, and read our homeowners insurance guide.
If you plan to stay only a few years, compare the total cost of owning with renting. Zillow's observed rent in September 2026 was $3,582 a month in San Jose and $3,972 in Sunnyvale.
Financing a Silicon Valley condo
Lenders review the building as well as the buyer. Ask your lender which project rules apply to your loan; they can cover the association's budget and reserves, insurance, pending litigation and how many units are owner-occupied. Ask your lender to review the HOA questionnaire early, before your loan contingency runs out.
FHA loans need the project to be on HUD's approved condominium list, which you can search by name and city on HUD's condo lookup. For conventional loans, the FHFA's 2026 conforming limit for one-unit homes is $832,750 in most of the country, with a ceiling of $1,249,125 in high-cost areas; check the FHFA county list for the Santa Clara County figure.
At the Freddie Mac average of 7.24% in the week of October 29, 2026, the county median condo of $667,393 with 20% down means a loan of about $533,914 and principal and interest of about $3,639 a month, before HOA dues, tax and insurance.

Silicon Valley condo buyer's checklist

- Ask for the latest balcony and exterior elevated element inspection report, if the building has them.
