How much does a Sotheby's International Realty franchise cost?

The March 2026 U.S. Franchise Disclosure Document gives two opening ranges: $47,250 to $331,950 to convert an existing real estate brokerage office, and $128,750 to $519,250 for a qualifying new start-up office. Each estimate includes a three-month operating allowance and assumes premises of 1,800 to 3,500 square feet for up to 30 people.

New-office path: $128,750–$519,250. That path adds $81,500 to $187,300 for planning, furnishings, deposits, prepaid expenses and extra operating funds. The price of real estate is not in either total. Source: 2026 FDD, Item 7, pp. 31–36.

Data basis. Legal franchisor: Sotheby's International Realty Affiliates LLC. Issued March 30, 2026. The analysis uses Items 5–7, pp. 23–36, cost-relevant portions of Items 8, 10, 11 and 17, and Franchise Agreement §11.6 in Exhibit C. Information checked July 22, 2026.

The offering appears on the Wisconsin active franchise registration list with an expiration date of March 30, 2027. No matching 2026 disclosure document was located on a franchise-controlled public domain, so the page references below are unlinked. The official brand website is linked as brand information only.

Key cost figures

These figures answer separate questions. A fee, a financial qualification and the complete opening range should not be added together.

Main Office initial fee $0 currently Published amount is $25,000; the March 2026 incentive waives it and may change.
Royalty Fee 6% Of Gross Revenue, payable when each transaction closes.
Brand Marketing Fund 2% Of Gross Revenue; $723 floor and $3,121 cap per office per month as of Jan. 1, 2026.
Liquid assets At least $75,000 Cash or securities readily convertible to cash under Agreement §11.6.
Tangible net worth Over $150,000 Excludes the franchise interest, related notes and working capital.
Start-up operating allowance $50,000–$100,000 Included in the new-office total for the first three months.
Format difference

Why are there two investment ranges?

The lower range assumes an operating brokerage is converting a location. The higher range assumes a newly formed qualifying brokerage must also plan, furnish and equip premises. Combining the two would obscure materially different obligations.

Cost implication

An operating brokerage may already have premises and systems, but the conversion schedule still allows up to $105,000 for Leasehold Improvements and up to $35,000 for Website work. The new-office path carries those categories plus the separate additions.

Office types change the fee contract

The two main ranges do not govern every approved location. Separate addenda apply to additional and limited-purpose formats.

Branch OfficeThe second carries a $12,500 initial fee; each later one carries $7,500. A negotiated Minimum Annual Royalty Fee may apply in certain markets.
Development OfficeNo initial fee as of the issuance date. Its separate minimum marketing-fund contribution is $117 per month.
Gallery OfficeThe initial fee is $3,750. Its monthly marketing-fund floor and cap are $117 and $3,121.
Satellite OfficeThe initial fee is $1,000. Conversion to a full branch can trigger the difference in the applicable branch fee.
Other Limited Purpose OfficeThe disclosed one-time range is $1,000–$3,750, subject to the relevant addendum and approval.
Main Office incentiveThe published $25,000 fee is waived as of March 30, 2026, but the incentive can be modified without notice.

Conversion budget

What does the conversion-office total include?

The disclosed total covers the entry fee, office work, signs, printed and digital materials, technology, launch expenses and a three-month operating allowance. The tables keep payment timing and payee visible without treating the low and high columns as a midpoint.

Contract, premises and operating runway

For the conversion path, this group covers entry, premises adaptation, insurance, legal work, orientation travel and the first three operating months.

Expenditure Disclosed amount Payee or timing qualification
Building Signs $750–$25,000 Suppliers; installation is not included in the large-sign estimate.

Premises exclusion

Real Estate is outside the official total. The document separately presents occupancy at $0 to $50,000 per year across a broad geographic area. Refurbishment may also be required when a location does not meet current standards, but no fixed estimate is provided because the work depends on its condition.

Start-up additions

What extra costs apply when opening a new office?

The separate add-on schedule covers planning, furnishings, deposits, prepaid expenses and extra operating funds. Furnishings and Communications Equipment has the widest disclosed category range; the operating allowance creates the largest minimum addition.

PlanningArchitect and consultant charges are paid before opening.
Furniture and communicationsSupplier purchases may include amounts paid to Anywhere Services Group.
DepositsUtility and landlord deposits are due before opening.
Prepaid expensesInsurance, licensing, permit and other advance charges go to carriers, government agencies and suppliers.
Operating allowanceEmployee salaries and benefits, royalties, the marketing contribution, utilities, communications and administrative or organizational costs are covered for three months.

Source: 2026 FDD, Item 7, pp. 35–36.

Working-capital caveat

The two operating-funds entries are already included in the complete new-office range. Personal or living expenses and debt service are excluded. The disclosure does not state that owner compensation is included.

Payment timing

When is the money paid?

Cash is due in stages rather than on one date. The heaviest concentration occurs before opening and during the first month after the agreement is signed.

At signingThe entry fee is due as a lump sum unless separately financed. The published entry amount is waived by the March 2026 incentive. It becomes fully earned and non-refundable when the franchisor countersigns, except when the application is not accepted.
Within 30 daysMost branded materials, computer capability, web implementation, launch work and interior branding are scheduled in this window.
Within 60 daysBuilding signage is due. Installation may add cost because the disclosed large-sign estimate excludes it.
Before openingPremises work, insurance and legal expenses are incurred; the new-office path also requires planning, furnishings, deposits and prepaid charges.
At the next scheduled OrientationTravel is generally placed within 180 days after signing. One qualifying attendee receives specified coverage in certain circumstances; each extra attendee currently carries a $1,500 registration charge plus travel expenses.
During the first three operating monthsThe allowance is spent on the categories identified above rather than paid as one invoice to the franchisor.

Most conversions are described as opening within 45 days after the Effective Date; a newly formed office typically opens within 45 to 60 days. Source: 2026 FDD, Item 11, p. 45.

Ongoing fees

Which fees continue after the office opens?

The two core continuing charges use the revenue definition stated in the agreement. Other obligations depend on the location, market, vendor choices, optional programs or future system changes.

Recurring and technology-related charges

The royalty and marketing contribution are the core percentage-based payments; the technology rows are current, possible future or vendor-dependent charges.

Fee or system cost Amount or basis Timing and qualification
Royalty Fee 6% of Gross Revenue Due when each transaction closes. A Luxury Premium Award may rebate up to 3% of qualifying Gross Revenue when all conditions are met.
Brand Marketing Fund contribution 2% of Gross Revenue Invoiced monthly, with a $723 floor and $3,121 cap per office per month as of Jan. 1, 2026; begins the month after opening.
Minimum Annual Royalty Fee Variable Reserved for new Branch Offices in certain markets; any shortfall is due January 10 of the following year.
Localization Platform / Productivity Suite No current base charge Enhancements, third-party products, MLS charges and API integration can cost extra.
Leads Engine $0 currently; possible $0–$5,000/year Not required as of issuance; later pricing is reserved.
Computer Software Maintenance and Support Possible $1,000–$3,000/year No current charge; the range estimates a future fee.
CIH Platform No current amount disclosed Optional; expected to be offered beginning in early 2027 and may later carry a charge.

Source: 2026 FDD, Items 6, 8 and 11, pp. 23–30, 36–37 and 48–50.

Fee-basis caveat

The royalty is due at closing, while the marketing contribution is invoiced monthly and has both a floor and cap. The conditional award does not alter the payment obligation when a transaction closes.

Which charges arise only after a specific event?

These obligations are not routine monthly expenses, but their triggers can make them material.

Transfer$5,000 before a transfer, subject to listed exceptions. Conditions also include current compliance, an audit, debt payment or assumption, a release and tail errors-and-omissions coverage.
AuditEstimated minimum of $450 per day when a trigger applies, plus underpayments, interest, late charges and costs. The per diem may rise by up to 10% annually.
Late paymentInterest is capped at 1.5% per month, plus the highest lawful late charge. Audit underpayments also carry interest at Prime plus 2%.
Early terminationLiquidated Damages use the combined monthly average of royalty, advertising and other agreement fees during the Calculation Period, without waivers or rebates, multiplied by the lesser of 36 or the full months remaining.
Additional termThe agreement gives no renewal right. A permitted additional term can require the then-current form, which may contain materially different fees and obligations; no fixed renewal fee is stated.
Training and conferencesExtra Orientation attendees carry the registration and travel charges described above. The optional Global Networking Event is $2,295–$2,495 per registrant; the Leadership Forum, when offered, is $2,695–$2,795.
Relocation or improvementA location that does not meet current appearance standards may require upgrades or relocation at supplier-set prices; no fixed range is stated.
Essential products and servicesAfter written notice, a required system purchase can create equipment, technology and service costs at then-current prices, with implementation within 90 days.
Special assistance and enforcementExtra assistance is negotiated. Agreement enforcement, attorneys' fees, insurance bought after a coverage failure, taxes and indemnified losses are variable.

Financial qualifications

How much liquidity and net worth must the franchisee maintain?

The agreement requires at least $75,000 in readily available funds and net assets above $150,000. These thresholds are separate from the opening estimate; they are not a down payment and should not be added to the official total.

Liquidity testCash or securities must be readily convertible to cash.
Net-worth calculationIt excludes the franchise interest, related notes and working capital.
Maintenance throughout the termA deficiency must be covered by a guarantor acceptable to the franchisor.
Guarantees and securityOwners and applicable spouses sign guarantees. Financing notes also use business-asset security, a UCC-1 filing and may pledge future Luxury Premium Award rights.

Source: 2026 FDD, Exhibit C, Franchise Agreement §11.6, pp. 15–16; Item 9, p. 42; Item 10, pp. 43–44.

Does the franchisor provide financing?

Financing is discretionary, not guaranteed. Sotheby's International Realty Affiliates LLC or a Related Party may offer a Conversion Promissory Note for conversion, opening or certain growth costs, or an Expansion Promissory Note for qualifying existing franchisees.

Financing comparison

Financing type Core terms Repayment and security
Conversion Promissory Note Amount varies; no down payment; the table states a 9–10 year term. Annual principal forgiveness may be available if revenue and compliance conditions are met. Equal annual installments; owner and spouse guarantees, business-asset security, UCC-1 and future rebate rights. Default interest can reach 18% per year or the lawful maximum.
Expansion Promissory Note Amount and term vary; available at the franchisor's discretion for acquisition or business-related expenses. No forgiveness. Principal is due in full six months before agreement expiration, with similar guarantees, collateral, acceleration and collection-cost exposure.

Need, credit history, repayment ability, net worth, operating history, stability and market-development needs may be considered. Source: 2026 FDD, Item 10, pp. 42–45.

Buyer verification

What should be confirmed before signing?

The buyer should reconcile the proposed location type, premises condition, supplier quotes and any financing terms against the current disclosure and final agreement or addendum.

Confirm the exact office path.Identify whether the proposal is a conversion, a newly created location, a branch, or an approved development, gallery, satellite or other limited-purpose format.
Put the fee waiver in writing.The current entry-fee incentive can change without notice, and negotiated funding may affect other financing availability.
Price excluded premises work.Obtain transaction-specific quotes for the lease, occupancy, refurbishment, installation, permitting and local compliance.
Separate free technology from later charges.Verify MLS, API, web enhancement, Productivity Suite, Leads Engine, software-support and CIH Platform pricing for the proposed launch date.
Read any location addendum.Check the entry fee, minimum annual royalty, separate marketing contribution and any term extension.
Review exit-cost formulas.Transfer conditions, tail insurance, audit obligations and early-termination damages can create costs after opening.
Obtain the latest disclosure update.The FTC franchise buying guide explains the 14-day disclosure rule and why updated information matters before signing or paying.

Cost synthesis. The conversion path has the lower opening range; the new-office path adds premises planning, furnishings, deposits and a larger operating allowance. Neither figure replaces the separate liquidity and net-worth tests, percentage-based continuing charges or costs triggered by later events. The most important unresolved amount is the buyer-specific premises work excluded from the disclosed total.
