Last Updated: July 2026 | Reading time: 11 min

If you own a property on or around Bagdat Avenue, you've likely heard the term "Kentsel Dönüşüm" (Urban Renewal) frequently. Perhaps a neighboring building has been demolished and replaced by a modern residence. As your building's turn approaches, the primary question on your mind is: What is the true value of my old flat today? Is the developer's offer fair? How can I protect my rights throughout this process? These are the fundamental concerns of property owners who seek our consultation.

This comprehensive guide was created to demystify the Bagdat Avenue urban renewal valuation 2026 process. Our goal is not to overwhelm you with technical jargon, but to clearly explain how to determine your property's value accurately, the steps involved, and your legal rights. As a real estate consultant with over 15 years of experience in this district, I have closely observed both the financial and emotional aspects of this journey. It's time to share this expertise with you.

What is Urban Renewal Valuation and Why is it Crucial?

Urban renewal valuation is the process by which SPK-licensed (Capital Markets Board of Turkey) experts determine the monetary value of your existing apartment, your land share (arsa payı), and other associated rights within a building identified as structurally unsafe. This is the most critical stage of the demolition and reconstruction process, as all negotiations, agreements, and your future profits are based on the figures in this valuation report.

This valuation is more than just the "sale price of the flat." It encompasses several key components:

• Land Share Value: The current market value of the portion of the land allocated to your flat in the title deed. This is where the real wealth lies in urban renewal.
• Building Value: The depreciated value of the current structure, often considered its debris value. This is typically low.
• Goodwill Value (Şerefiye): The positive or negative value difference of your flat compared to others in the building, based on its location (façade, floor, view, etc.).
• Entitlement in the New Project: The calculated value of the new flat you will receive in the reconstructed building, based on today's project value.

Key Factors Influencing Bagdat Avenue's 2026 Market

As of 2026, the dynamics of urban renewal on Bagdat Avenue show some differences compared to previous years. These current factors must be considered during valuation.

Rising Construction Costs and Land Values

Global supply chain issues and currency fluctuations in 2024 and 2025 significantly increased the costs of all construction materials. This has made developers more cautious with their flat-for-flat offers. However, in parallel, the brand value of Bagdat Avenue and its land prices continue to set records. Land values per square meter, especially on plots near the sea in locations like Caddebostan, Göztepe, and Suadiye, saw increases of over 15% in the first half of 2026.

New Zoning Regulations and Gains

Zoning plan updates by the Kadıköy Municipality at the end of 2025 introduced additional building rights (emsal) or height allowances for certain parcels. Your appraiser's consideration of these latest zoning regulations directly impacts your land share's value. For instance, if a mixed-use (commercial + residential) plot allows for commercial units on the ground floor, the project's total value increases, positively affecting the owners' shares.

Investor Profile and Demand

Bagdat Avenue is not just a residential area; it's an international investment hub. Demand from investors, particularly from the Gulf and Europe, drives up the prices of new, luxury residences. This demand indirectly increases the value of your old building's land. The appraiser must analyze not only the current situation but also the area's future potential.

The Legal Framework: Law No. 6306

The cornerstone of urban renewal in Turkey is Law No. 6306 on the Transformation of Areas Under Disaster Risk. All valuation processes and your rights are protected under this law and its associated regulations. While the law grants significant rights to property owners to ensure a swift process, it also imposes certain responsibilities.

The law's most critical provision regarding valuation is the ability to make decisions with a two-thirds (2/3) majority of the co-owners. If 2/3 of the owners in your building agree with a developer and the sharing ratio, the shares of the dissenting 1/3 minority can be sold at public auction to other stakeholders at a value determined by an SPK-licensed firm. This is why having an accurate, independent valuation report is essential to prevent financial loss.

Step-by-Step Guide to the Urban Renewal Valuation Process

To help you understand the process clearly, let's break down all the stages in practical terms.

Step 1: Risky Structure Identification Report

It all begins with identifying your building as structurally unsafe. Any co-owner can apply to a firm licensed by the Ministry of Environment, Urbanization and Climate Change to obtain a "Risky Structure Report." If the report is positive, the official process starts. (Timeline: 1-2 Weeks)

Step 2: Selecting an SPK-Licensed Appraiser

Once your building is classified as a risky structure, the co-owners should convene to hire an independent, SPK-licensed real estate valuation company. When making this choice, be sure to inquire about the firm's experience and references specifically within the Bagdat Avenue area. (Timeline: 1 Week)

Step 3: Preparation of the Valuation Report

The appraiser will visit your building to inspect each independent unit (flat, shop, etc.). They will analyze title deed records, the municipal zoning file, and market data. Typically, a combination of three main valuation methods is used:

• Sales Comparison Approach: Compares prices of similar old and new properties sold in the immediate vicinity within the last 6 months.
• Cost Approach: Calculates the value of the land plus the cost to construct the same building from scratch, minus depreciation.
• Income Approach: Primarily for commercial units like shops, this method calculates a value based on the property's potential net rental income.

The appraiser synthesizes these methods to determine a final value for each flat. (Timeline: 2-3 Weeks)

Step 4: Goodwill (Şerefiye) Valuation and Distribution

This is a critical part of the report. The expert creates a goodwill table by scoring all units based on factors like location, façade (north/south), view, floor, and noise level. This table forms the basis for deciding who gets which flat in the new project and how value differences will be compensated. For example, if an owner of a middle-floor flat in the old building has to accept a ground-floor unit in the new project, they have the right to claim the goodwill difference in cash.

What to Look for in a Valuation Report

When you receive the valuation report, review the following points with a lawyer or real estate consultant:

• Date and Relevancy: The report should be dated within the last 3 months. A report older than 6 months will not reflect the current market.
• Comparable Properties (Comps): The report should clearly list the addresses, sale dates, and prices of the comparable properties used. Verify that these comps are genuinely similar to your property.
• Zoning Status Accuracy: The zoning status (building ratio, number of floors, etc.) mentioned in the report must match the most recent document from the municipality.
• Goodwill Criteria: Ensure the criteria used for the goodwill calculation (view, facade, floor, etc.) are fair and logically weighted.
• Legal Compliance: The report should contain statements confirming it was prepared in accordance with SPK and Law No. 6306 formats.

Comparison: Enter Renewal vs. Sell As-Is

A common question from property owners is, "Would I be better off selling my flat as-is instead of dealing with the renewal process?" Let's clarify this with a comparison table:

Frequently Asked Questions (FAQ)

Who pays for the urban renewal valuation?

Typically, the cost is shared among the co-owners, distributed according to their land share percentages. If a developer offers to cover this cost, it is wise to question the independence of the valuation firm.

The value of the new flat offered by the developer is lower than my old flat's valuation. What should I do?

In this situation, you have the right to object using your independent valuation report. You are not obligated to sign any contract unless the 2/3 majority is reached. You can demand the value difference be paid in cash or request an additional share in the project (e.g., a storage unit).

How is the goodwill (şerefiye) difference calculated and paid?

It is calculated based on the points in the goodwill table prepared by the SPK-licensed expert. After the new flats are distributed (often by lottery), an owner who receives a more valuable flat compensates an owner who receives a less valuable one. The method and timing of these payments must be clearly defined in the construction agreement.

Can I object to the valuation report?

Yes, you can. If you believe there is a clear error in the report (e.g., incorrect zoning status, flawed comparable sales), you can request a correction from the firm that prepared it. If the dispute continues, you can hire a new valuation firm or take legal action.

Is the valuation for commercial units like shops different?

Yes, it is. For shops, factors like location (corner, foot traffic), storefront width, and rental income potential are much more significant. A combination of the income and sales comparison approaches is typically used, making the calculation more complex than for residential units.

What happens if the 2/3 majority is reached, but I refuse to sign?

According to Law No. 6306, the shares of the dissenting 1/3 minority, including yours, are first offered for sale to the other co-owners who have signed the agreement. If there are no buyers, the share may be acquired by the Treasury. The sale price is based on a value determined by another SPK-licensed institution. This underscores the critical importance of an accurate initial valuation.

Does the government provide rent assistance during urban renewal?

Yes. Owners who have vacated their flats in a building identified as a risky structure can apply to the Ministry of Environment, Urbanization and Climate Change to receive monthly rent assistance. The amount is re-evaluated annually and varies by city.
