What matters when valuing property in Treasure Island & Yerba Buena Island
Treasure Island and Yerba Buena Island share an MLS search label but have different physical settings within a major redevelopment area. A valuation should identify the actual offering, tenure and completed building before comparing it with another island property or mainland condominium.
Establish the land interest
Review the specific title and any ground-lease or public-trust arrangements affecting the offering. Do not assume all island housing is unrestricted fee ownership; a transaction involving a different tenure needs explanation before it can support the broker's range for the subject property.
Completed home and infrastructure
Compare the residence's actual accommodation, access and delivered facilities with selected closed sales. A master plan and future amenity schedule provide context, but anticipated improvements should not be presented as existing features or guaranteed benefits already available to a purchaser at this address.
Building costs and site evidence
Review governing finances, parking and collective responsibilities alongside relevant property information. The broker's analysis should distinguish the two island settings and describe material assumptions, avoiding a single redevelopment-wide price adjustment that overlooks differences in rights, ground conditions or the ownership package actually offered.

How the valuation conversation works
1. Understand the property
We start with your address, property type, approximate size and the improvements you tell us about. Where a detail is uncertain, we identify the records or follow-up needed before relying on it.
2. Build the comparison
We consider relevant closed sales and current competition. Location, ownership type, condition, usable space and sale timing help explain why one property is a more useful comparison than another.
3. Discuss the range
We explain the evidence, assumptions and limits behind a market range. If a visit, specialist input or additional documents would change confidence in the estimate, we discuss that next step.
Questions about your Treasure Island & Yerba Buena Island valuation
How do you choose comparable properties in Treasure Island & Yerba Buena Island?
The comparison starts with the actual address in Treasure Island & Yerba Buena Island, then narrows to relevant nearby sales and similar property and ownership types. A place name alone does not establish that two properties are comparable.
Is this an instant home estimate or a formal appraisal?
No. This form requests a broker comparative market analysis. Automated estimates organize available data, while a broker review can consider details those tools miss. A lender, court or tax matter may require a qualified appraiser and a separately defined assignment.
Can you review a condo, land, vineyard or investment property?
Tell us the property type and intended use of the analysis. A condo requires the correct ownership and association comparison. Land and agricultural or income property need different evidence from a standard house. We will discuss scope and whether additional specialist work is needed.
What information should I provide?
The full address or parcel number, your name and email are the starting point. Helpful optional details include approximate size, recent improvements, known condition issues and your possible selling timeline. Please do not send identification documents, account numbers or sensitive financial records through the form.
Is my property-tax assessed value the same as market value?
Not necessarily. An assessment serves the property-tax system and can reflect rules that differ from a current sale comparison. A broker market analysis considers the subject property and relevant market evidence rather than treating the tax figure as its likely sale price.
Does requesting a valuation commit me to listing?
No. Sending this request asks us to contact you about the property. Brokerage representation, compensation and any listing instructions require a separate discussion and the appropriate written agreement. Review the iHomefinder form’s contact choices before submitting; the marketing text checkbox is a separate choice.
Ready to understand the comparison?
Start with the address and your goal. We can discuss what is known, what needs checking and how the evidence relates to your next decision.
Request my property valuationWhat affects home values in Treasure Island
Treasure Island and Yerba Buena Island are being rebuilt on the former naval station, with up to 8,000 homes planned, and most sales so far are new condominiums with a median build year of 2022. With a young, growing stock, a broker compares sales within the same building or phase first and adjusts for floor, view, layout, parking and HOA dues. Ownership arrangements are unusual. Land comes from the Navy through a local authority in phased transfers, a master developer builds the project, and part of the islands is state public trust land, so a broker reviews how a property’s parcel and title fit those arrangements. Ground conditions have been addressed directly: the Treasure Island fill lies in a liquefaction zone, but it has been reengineered with ground improvement and sea-level design. Access by ferry to the Ferry Building, the 25 Treasure Island bus and the Bay Bridge shapes appeal. A broker values a Treasure Island home by comparing recent island sales, adjusted for these points.

Which sales are comparable for a Treasure Island condo?
Sales in the same building or phase come first, since most homes are new condos built around 2022. A broker adjusts for floor, view, layout, parking and HOA dues, and adds other island sales as more homes are finished.
Does the liquefaction zone affect Treasure Island values?
The fill lies in a liquefaction zone, but it has been reengineered with ground improvement and sea-level design. The zone still appears in disclosures, so a broker reviews the building’s documentation with buyers.
How does public trust land affect a Treasure Island property?
Part of the islands is state public trust land, and Navy parcels transfer in phases through a local authority. A broker reviews how your parcel fits these arrangements, since buyers will ask about title.
