Property Portfolio Concentration by District District concentration should be measured by more than unit count. Calculate exposure by portfolio value, net operating income and debt because one expensive leveraged asset can dominate risk even if several smaller units sit elsewhere.
Identify district-level correlated risks: tenant demand, local employment, infrastructure dependence, zoning/urban-transformation changes, new supply and access disruptions. Nearby districts with the same demand driver may not provide meaningful diversification.
Stress-test a district-specific shock—rent decline, longer vacancy, delayed sale or major infrastructure disruption—and compare how much portfolio cash flow and equity are affected before adding another property in the same area.
From market data to testable cash flow
Calculate gross yield from annual rent relative to price, then calculate net yield after vacancy, management, maintenance, insurance, taxes, dues and non-recoverable costs. For a capitalization rate, use NOI before debt service and distinguish property performance from leveraged equity return. For each fact use a source capable of proving it and link the result to its effect on purchase, ownership or cost. Any rent-growth, resale-price or interest-rate assumption should be stress-tested with alternative scenarios rather than accepted as a single forecast.
Property investment analysis must separate market data from the calculation for the specific asset. The review becomes useful when the finding is tied to a defined effect on rights, price, cost or executability and backed by evidence that can be rechecked later. TCMB publishes the House Price Index to track housing-market price movements and, in 2026, began publishing the New Tenant Rent Index to capture new-rental price developments more quickly than rent measures that include existing contracts. These indices do not provide the sale price or rent of one unit, so they must be combined with verifiable local comparables. Turn the review topic into provable facts: identity, date, amount, registry status, document or technical condition. For each fact use a source capable of proving it and link the result to its effect on purchase, ownership or cost. Read this evidence together with the “Taxes that depend on year and owner status” review before relying on the conclusion.
Taxes that depend on year and owner status
For each fact use a source capable of proving it and link the result to its effect on purchase, ownership or cost. Rental income is governed separately by GİB rules, so distinguish rent actually received, deductible expenses, the chosen expense method and the resident/non-resident position of the owner. On exit, disposal of certain real property within five years of acquisition can fall under value-increase gain rules of the Income Tax Law, subject to the owner’s circumstances and statutory exceptions. Keep returns, receipts and cost evidence because they affect both verification and resale analysis.
A property tax file is not proved by one receipt. The review becomes useful when the finding is tied to a defined effect on rights, price, cost or executability and backed by evidence that can be rechecked later. Municipal property tax depends on the tax value, property category and location, and GİB states that values calculated for 2026 are subject to a specific cap relative to 2025 values; obtain the current value and debt position from the competent municipality when it matters rather than carrying an old figure into a new year. Turn the review topic into provable facts: identity, date, amount, registry status, document or technical condition.
Payment trail and beneficiary proof
Match beneficiary name, bank account, currency, amount and transfer reference to the contract and to the seller or properly authorised recipient, and independently verify any change in payment instructions before sending funds. A request to use a new account, a third party or a route outside the agreed structure is a stop signal until authority and reason are resolved. For each fact use a source capable of proving it and link the result to its effect on purchase, ownership or cost. TKGM also has specific foreign-exchange purchase-document instructions for foreign transactions where they apply, so not every bank receipt serves the same legal purpose. For each fact use a source capable of proving it and link the result to its effect on purchase, ownership or cost. Read this evidence together with the “Taxes that depend on year and owner status” review before relying on the conclusion.
Preserve the transfer order, bank confirmation, posting evidence and a reference linking the transfer to the exact instalment. Keep a reservation deposit, sale price and brokerage commission separate, and never replace an auditable banking trail with an oral confirmation. The review becomes useful when the finding is tied to a defined effect on rights, price, cost or executability and backed by evidence that can be rechecked later. The payment path is part of transaction due diligence, not a separate bookkeeping step. Turn the review topic into provable facts: identity, date, amount, registry status, document or technical condition.
2026 analytical update — Property Portfolio Concentration by District
Geographic diversification is not achieved by owning two units in adjacent districts exposed to the same demand driver. Measure concentration by asset value, NOI, tenant type, developer and project stage, then stress a prolonged slowdown in one district.
TÜİK reported 123,603 home sales in July 2026; 23,888 were mortgaged (19.3%), with 42,529 first-hand and 81,074 second-hand sales. Foreign-buyer sales were 2,120, or 1.7% of the total.
Formula / check: District concentration = each district exposure / total portfolio value; also measure income and tenant concentration separately.
