AI starting opinion
AI gives the value. This worksheet lets you prove it or adjust it. Use the research, choose comps and refine assumptions to support your conversations with a banker, lender, partner or buyer.
Estimated market value as of September 17, 2026. The property is currently offered at $7,200,000, but nearby office/flex asking prices and the risk associated with vacant SoMa office space indicate a probable transaction below asking. This is an estimate, not an appraisal.
Starting assumptions and sources
- Fee-simple interest with marketable title and no material environmental, structural or seismic defects beyond disclosed conditions.
- Approximately 14,475 square feet of rentable/building area on roughly 0.15β0.17 acre.
- Vacant and available for owner occupancy or lease as indicated by current marketing.
- High-quality 2004-era renovation, elevator, HVAC, kitchen, showers and seismic work are functional.
- No extraordinary entitlement, conversion or redevelopment premium is included.
- Research cutoff is September 17, 2026.
Research basis
Confirmed as one commercial property, APN 3757-046, publicly addressed as both 455 9th Street and 455-457 9th Street; 457 is not identified as a separately deeded property. Avison Young's active LoopNet/Crexi offering asks $7,200,000 ($497/SF), marketed February 24, 2026 and publicly available as of the research date. The 14,475 SF offering comprises 6,409 SF on each full floor plus a 1,657 SF mezzanine. Lot area uses the 0.150-acre parcel figure reported by Crexi and LoopNet's property record; the marketing page separately rounds it to 0.17 acre.
Sales starting assumptions and sources
- Comparable offerings are indicators rather than verified closed sales.
- Indicated subject range is approximately $400β$497 per square foot.
- The building's superior finishes offset part, but not all, of the broader SoMa office-market weakness.
- No major capital expenditure is immediately required.

Reconciled starting assumptions: The saved selected-comp calculation starts at $8,369,159. An overall adjustment of -21.139034% was calculated to reproduce the new $6,600,000 AI Sales opinion. This is an editable reconciliation assumption, not a change to comp prices or independent evidence of value. These assumptions reproduce the AI opinion; they are not independent confirmation of it.
How Sales works: Sales starts with the AI opinion above. Compare the property with similar properties using prices per square foot or per unit, then choose Worksheet calculation in Value summary to use your selected comps. Asking prices are seller expectations, not completed transactions; the price basis is shown below.
Improve your estimate: Click any property address to see what Google finds, then fill in or correct the compβs price, building size and other details here. Our research focuses on your subject property, so we donβt fully investigate every comparable. Verifying and completing the comps you choose is one of the best ways to make your estimate more accurate.
All comps are selected to start, with equal weights. Change any selection or weight. Grades are guidance and do not change weights. All candidates stay in this table. Use selects a comp for calculations and print; unchecking it keeps the row here. A/B/C filters only change visibility. $/SF and $/unit work independently.

Research basis
Research reflects listings and reported transactions available as of September 16, 2026. The search began in the subject's West SoMa/Showplace Square/Mission Bay corridor and then expanded within San Francisco. The strongest physical candidates are the smaller freestanding Class B, creative-office and brick-and-timber buildings in SoMa. Closed sales at the subject's scale remain limited, so active asking-price evidence and useful incomplete local leads are preserved separately; asking prices must not be treated as closed-sale prices. Distances are null because defensible straight-line measurements were not published in the reviewed sources.
Owner-user offering; three stories plus parking garage. Listing states exposed brick and timber, seismic upgrade, open floor plans, elevator, HVAC and renovated creative interiors.
Current listing identifies a 100%-leased office building and a reduced asking price; investment occupancy differs from the subject's vacant/owner-user orientation.
Whole-building office offering built in 1972. Asking price is not a closed-sale indication.
Three-level creative office offering near Oracle Park. Marketing reports approximately 20% month-to-month occupancy and substantial owner-user flexibility.
Older 1923 freestanding commercial building in the subject's immediate market; potentially relevant to creative-office users, but listed as industrial.
Whole-building offering built in 1927 and reported as 100% leased. Retained because its scale and older adaptable commercial-building form are relevant.

Income starting assumptions and sources
- Market rent is $48β$54 per square foot annually on a full-service-equivalent basis.
- Stabilized economic occupancy is 85%β90%.
- Operating expenses, reserves and ownership costs consume 33%β38% of effective gross income.
- Capitalization rate is 6.5%β7.25%, reflecting vacant Class B/creative-office risk.
- Lease-up costs, commissions, concessions and downtime are reflected through the range rather than a separate discounted-cash-flow calculation.
Use the details below to prove or adjust this opinion. In Value summary, choose the AI opinion, your worksheet calculation or your own value.
Reconciled starting assumptions: $51/SF/year and a 7.25% cap rate use the AI ranges. The worksheet keeps its editable 95% occupancy default; the AI answer instead described 85%β90%. This 95% scenario uses $251,813.75 expenses, about 35.9% of effective income, to reproduce the opinion. Annual operating expenses of $251,814 were calculated to reconcile the inputs to $6,200,000. These are editable starting assumptions, not verified operating accounts. These assumptions reproduce the AI opinion; they are not independent confirmation of it.
How Income works: Estimate the annual income left after vacancy and operating expenses, before loan payments and income taxes. This net operating income (NOI), divided by a market capitalization rate (cap rate), gives an income-based value indication.
Commercial lane: rent is handled by rentable square feet per year.
Research basis
Estimated full-service-gross-equivalent market rent as of September 2026. Immediate-area asking observations range from $36 to $48/SF/year, including $36 on the same 9th Street corridor, $45-$48 for nearby Class B/creative space, and Q2 2026 averages of $41.05 for Showplace Square and $43.46 for San Francisco Class B office. The subject's separately reported $48 asking rent was not treated as independent market evidence.
Q2 2026 Showplace Square total office vacancy was 23.5%; direct vacancy was 19.6% and total availability was 32.8%. Total vacancy is adopted because it reflects both direct and sublease competition in the subject's immediate creative-office market.
Estimated at approximately $12.50 per rentable SF annually for a low-rise, comprehensively renovated standalone office operated on a full-service-gross-equivalent basis. The budget includes property taxes, insurance, utilities, janitorial, repairs and maintenance, management/administration, and replacement reserves. The reported $3,765,667 assessment provides property-tax context, but no current subject operating statement was published. No tenant reimbursements are assumed in other income, avoiding double counting; if leased industrial gross or NNN, tenant-paid utilities or recoveries should instead reduce owner expenses or be recorded as reimbursement income.
Practical stabilized Class B creative-office input synthesized from the August 2026 Kidder Mathews San Francisco CBD office cap-rate indication of 7.34% and a separate year-end 2025 San Francisco office market indication of 7.4%. Rounded upward to 7.5% for the subject's non-CBD location, single-tenant concentration, smaller owner-user format, and leasing risk. These are NOI capitalization rates, not gross yields.
Income inputs are for 14,475 rentable SF. Market rent is modeled as full-service-gross-equivalent because the principal market reports quote gross/full-service asking rents. Operating expenses therefore include owner-paid recoverable and nonrecoverable costs, with no reimbursement income. Subject asking rent is reported only as context and remains separate from the independent market-rent estimate. No potential income, NOI, or property value was calculated.

Cost starting assumptions and sources
- Land contains approximately 6,500β7,400 square feet and is valued near $400β$460 per land square foot.
- Replacement cost for the renovated office improvements is approximately $550β$700 per building square foot before depreciation.
- Combined physical, functional and external depreciation is approximately 40%β50%.
- Existing seismic upgrades and usable improvements reduce physical depreciation relative to an unrenovated 1924 building.
Use the details below to prove or adjust this opinion. In Value summary, choose the AI opinion, your worksheet calculation or your own value.
Reconciled starting assumptions: $575/SF and $3.1M land use the AI ranges. The original 14,475 SF remains unchanged. Total depreciation of 48.336712% was calculated to reproduce $7,400,000 including land. These are editable starting assumptions, not independent confirmation of the AI value. These assumptions reproduce the AI opinion; they are not independent confirmation of it.
How Cost works: Estimate what it would cost to replace the building today, subtract depreciation for age, condition and obsolescence, then add the land value.
Research basis
Practical September 2026 replacement-cost input for a small, fully finished Class B creative-office building in San Francisco. The estimate is slightly above the inflation-adjusted RLB secondary-office upper benchmark of approximately $561/SF and is consistent with Newmark's $500+/SF ground-up office indication. The selected $575/GBA recognizes the subject's relatively small scale, two floors plus mezzanine, elevator, full HVAC, creative-office finishes and current seismic/code requirements. No separate soft-cost, contingency or entrepreneurial-profit increment was added.
Estimated combined real-property depreciation/obsolescence. The building is 102 years old, but its effective condition is materially better than its chronological age because it was comprehensively renovated and seismically upgraded in 2004 and is currently marketed with high-end finishes, full HVAC and elevator access. The renovation is now approximately 22 years old, supporting meaningful physical and system depreciation. Functional risk includes an older two-story/mezzanine configuration, while external obsolescence remains material: Kidder Mathews reported 33.2% total SoMa office vacancy in Q2 2026. The compact standalone owner-user format and move-in-ready condition offset part of that market weakness. A reasonable uncertainty range is approximately 38%-52%, with 45% adopted overall.
Estimated at $400 per 6,534-SF site square foot. This is synthesized from verified San Francisco appraisal comparables including 1035 Howard Street at $286/site SF, 360 5th Street at $389/site SF, 300 5th Street at $356/site SF and 1601 Mission Street at $466/site SF. The selected rate recognizes the subject's smaller corner site and SoMa location while remaining below the $714/site-SF entitled Stevenson Street sale. The subject's $2,462,171 assessed land allocation is retained only as context and is not treated as market value.

Value summary
These editable worksheet assumptions start at the AI approach opinions. Changing inputs changes the calculated values below. Original AI opinions remain visible; select one again at any time. Your final conclusion is yours.
AI suggested weights: 55% Sales Β· 30% Income Β· 15% Cost. Sales receives 55% because this is likely an owner-user property and several nearby offerings provide direct price-per-square-foot evidence. Income receives 30% because leasing economics matter, although the building is currently vacant and projected income is uncertain. Cost receives 15% because substantial age, depreciation and office-market obsolescence reduce its reliability.
