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.

Key cost figures
These figures answer separate questions. A fee, a financial qualification and the complete opening range should not be added together.
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.
The teal bar reaches the disclosed maximum; the black marker identifies the minimum. Scale: $0 to $519,250.
Interpretation: the new-office path has both the higher floor and ceiling because a separate $81,500–$187,300 add-on schedule is combined with the conversion schedule. Labeled values are official; bar positions are proportional calculations. Source: 2026 FDD, Item 7, pp. 31–36.
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.

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 | When paid and payee |
|---|---|---|
| Initial Franchise Fee | $0–$25,000 | At signing; paid to the franchisor. |
| Leasehold Improvements | $0–$105,000 | Progress payments before opening; paid to contractors. |
| Insurance | $500–$4,000 | Before opening; paid to rated carriers. |
| Legal Expenses | $0–$4,000 | As incurred before opening; paid to attorneys. |
| Orientation travel | $400–$2,700 | At the next scheduled session; paid to travel providers. |
| Additional Funds | $15,000–$40,000 | During the first three months; paid to operating counterparties. |
Signs, printed materials and interior branding
Building signage is scheduled within 60 days after signing. The remaining listed brand materials are generally scheduled within 30 days and must follow the system's identity and supplier standards.
| Expenditure | Disclosed amount | Payee or timing qualification |
|---|---|---|
| Building Signs | $750–$25,000 | Suppliers; installation is not included in the large-sign estimate. |
| Yard Signs and Frames/Posts | $6,700–$12,000 | Approved suppliers. |
| Open House Signs | $900–$2,500 | Approved suppliers. |

Technology, data and launch

| Expenditure | Disclosed amount | Timing and payee |
|---|---|---|
| Computer Equipment for Electronic Data Transfer System | $6,000–$12,000 | Within 30 days; paid to suppliers. |
| Website | $1,000–$35,000 | As incurred within 30 days; paid to suppliers. |

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.
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.
Each bar begins at the disclosed minimum and ends at the disclosed maximum. Scale: $0 to $87,500.
Interpretation: the chart compares compatible line-item ranges without selecting midpoints or turning them into shares. Labeled values are official; bar positions are proportional calculations. Source: 2026 FDD, Item 7, p. 35.
Source: 2026 FDD, Item 7, pp. 35–36.
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.
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.
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.
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. |

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.
Source: 2026 FDD, Item 6, pp. 26–30; Item 17, pp. 62–68.
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.
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.
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.
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.
