Annual Property Ownership Budget Core point Split the annual ownership budget into
Annual Property Ownership Budget Core point Split the annual ownership budget into recurring operating costs, capital reserve and contingent costs rather than putting everything under “maintenance”. How to verify it Keep aidat, insurance, tax and routine maintenance separate from major replacements, vacancy and emergencies.
Decision impact Use a 12-month or seasonally representative view instead of annualising one unusually quiet month. Annual ownership budget Build an annual property budget from fixed and variable costs rather than using gross rent as “profit.” Include Aidat, routine maintenance, emergency repairs, municipal property tax, expected rental-income tax, DASK and other insurance, management costs and a vacancy allowance.
The supplied material suggests reserving a portion of expected income for vacancy and maintaining a separate emergency/maintenance provision. Required evidence Use historic Aidat statements, invoices and operating costs from the previous year, current tax assumptions and updated insurance quotations.
Separate operating expenses from capital expenditure and financing so the investor can see each layer of return. Decision points A high Aidat burden can reduce the rent a tenant is willing to pay and therefore compress the owner’s net cash flow.
The source offers practical reserve references such as roughly 1–2% of property value or around one month of annual rent for maintenance/emergencies, but the final reserve should reflect the actual building, equipment age and risk. Update the budget every year rather than recycling the acquisition-year estimate.
Source budget points: The source uses a 5–10% vacancy allowance and suggests an emergency/maintenance reserve around 1–2% of property value or about one month of annual rent.
From market data to testable cash flow
These indices do not provide the sale price or rent of one unit, so they must be combined with verifiable local comparables. For each fact use a source capable of proving it and link the result to its effect on purchase, ownership or cost. 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.
The financial effect should be expressed in a traceable number—price, cash flow, tax, amount at risk or remediation cost—not in a vague label such as “acceptable”. 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. 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. Turn the review topic into provable facts: identity, date, amount, registry status, document or technical condition.
Taxes that depend on year and owner status
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. For each fact use a source capable of proving it and link the result to its effect on purchase, ownership or cost. Keep returns, receipts and cost evidence because they affect both verification and resale analysis. A property tax file is not proved by one receipt.
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. The financial effect should be expressed in a traceable number—price, cash flow, tax, amount at risk or remediation cost—not in a vague label such as “acceptable”. 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.
