The model should keep statutory fees in their legal currency, property price in USD and rent in TRY unless a signed lease says otherwise. TCMB rent, price and credit series can frame the scenario, but they do not predict FX.
What changes the buyer's decision?
A high TRY rent can weaken in USD terms. A USD instalment can become heavy if income is in TRY. Taxes and Aidat may move differently from rent.
Build a budget table that shows break-even rent and net cash flow under multiple currency cases.
Evidence and checklist
| Buyer moment | Check | Why it matters |
|---|---|---|
| Price | USD | Property prices use USD across article surfaces. |
| Rent | TRY unless leased otherwise | Model income in the currency actually received. |
| Fees | Legal currency | Taxes and fees stay in their statutory currency. |
| Sensitivity | No FX forecast | Show cases, not predictions. |
| Instalments | Currency match | Compare income currency with payment currency. |
