Property Purchase Cost Budget Checklist Purchase budgeting should start with total acquisition cost, not listing price: purchase price, title/transaction fees, taxes where applicable, valuation/legal/translation costs, financing charges, insurance and initial repair/furnishing can occur at different dates. Separate one-off acquisition costs from recurring ownership costs such as aidat, maintenance, insurance, municipal tax, utilities during vacancy and financing; otherwise a property can be affordable to buy but expensive to hold.
From market data to testable cash flow
For each fact use a source capable of proving it and link the result to its effect on purchase, ownership or cost. For a capitalization rate, use NOI before debt service and distinguish property performance from leveraged equity return. 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 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”. 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. Calculate gross yield from annual rent relative to price, then calculate net yield after vacancy, management, maintenance, insurance, taxes, dues and non-recoverable costs. Turn the review topic into provable facts: identity, date, amount, registry status, document or technical condition.
Taxes that depend on year and owner status
Turn the review topic into provable facts: identity, date, amount, registry status, document or technical condition. 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. 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.
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”. For each fact use a source capable of proving it and link the result to its effect on purchase, ownership or cost.
Payment trail and beneficiary proof
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. 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 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”. The payment path is part of transaction due diligence, not a separate bookkeeping step. 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. Turn the review topic into provable facts: identity, date, amount, registry status, document or technical condition.
