Property investors model gross yield, occupancy and capital growth down to the decimal — and then overlook the one rule that decides how fast their money actually reaches the seller. Turkey's foreign-currency conversion requirement, evidenced by the DAB certificate, is not just legal paperwork. It is a line item on your deal's cost and a constraint on your timeline. Here is how it touches returns.
The currency rule in one paragraph
Since January 2022, a foreign buyer's purchase money has to arrive in foreign currency, be sold to a Turkish bank, and be converted to lira before the Land Registry will register the sale. The bank issues a Döviz Alım Belgesi (DAB) — Foreign Currency Purchase Certificate — recording the buyer, the USD-equivalent amount, and a statement that the exchange was made under Article 13 of the Central Bank's Capital Movements Circular. Without it, the Web-Tapu system rejects the transfer.
Why the FX spread is a real line item
Every investor focuses on price; fewer model the cost of getting that price into lira. The conversion happens at the CBRT rate, but the round trip — international wire, handling charges, and the spread between your home-currency value and the lira you receive — is money that never appears in your rental-yield spreadsheet unless you put it there.
| Purchase price | Indicative transfer + handling | As % of price |
|---|---|---|
| €150,000 | €300–600 | ~0.2–0.4% |
| €300,000 | €450–900 | ~0.15–0.3% |
| €500,000 | €600–1,200 | ~0.12–0.24% |
The figures are illustrative, but the point holds: on a buy-to-let where the first-year net yield might be 5–6%, even a few tenths of a percent of friction is worth pricing in before you commit.
Timing the conversion: deal speed and rate risk
The DAB can be produced the same day you instruct the bank, but the international transfer that feeds it can take several working days. For an investor racing a motivated seller or a price that may move, that lag is the real risk. Two consequences follow:
- Lock your banking before you negotiate hard. A pre-opened Turkish account and tax number turn a multi-day delay into a same-week close.
- Decide when you accept the rate. The longer your funds sit between home and Turkey, the more exposed you are to lira movements on the amount you ultimately convert.
Investors who treat the conversion as an afterthought lose the speed advantage that wins competitive deals — the kind of buying-season timing we cover in Alanya Buying Season Is Open: A Practical Guide for 2026 Property Buyers.
How it interacts with your yield math
The DAB amount cannot be lower than the price declared on the title deed. That has a quiet implication for investors who like to understate purchase prices to trim transfer tax: the strategy collides with the currency rule, because the certificate and the deed have to agree. Declare low, and the registry flags the mismatch; declare honestly, and your cost base — the number your future capital gain is measured against — is set correctly from day one.

Compliance so your exit isn't blocked
A clean DAB does more than unlock the purchase. When you eventually sell, a transparent acquisition trail — currency brought in, converted, and matched to the declared price — supports a clean capital-gains position and a smoother transfer to the next buyer. Sloppy documentation at entry becomes friction at exit. The investors who compound returns are the ones who treat the DAB as part of the asset's paper trail, not a one-off hurdle.
A worked example: where the rule shows up in the model
Picture a €250,000 two-bedroom bought to let. You wire euros to your Turkish account, instruct the bank to sell to the CBRT, and receive lira plus a DAB matching the €250,000 declared on the deed. The conversion friction — wire fee, handling, spread — might run a few hundred euros. Against a first-year net rental income of, say, €12,000–14,000, that one-off cost is a fraction of a single month's rent. The far larger risk is timing: if your funds are still in transit when the seller's patience runs out, you can lose the unit entirely. The math of the DAB is therefore less about the fee and more about protecting the deal you have already underwritten.
Repatriating income and sale proceeds
The discipline that gets you in cleanly also gets you out cleanly. Because the DAB documents that capital genuinely entered Turkey in foreign currency, it underpins your later ability to evidence the source of funds when you repatriate rental income or sale proceeds. Investors who keep their DAB, valuation report and bank confirmations together build an audit trail that smooths both the eventual resale and any cross-border tax reporting in their home country. The certificate you treat as a closing hurdle today is the same document that defends your numbers years later.
The bottom line
For investors, the DAB is three things at once: a small cost, a timing constraint, and a compliance asset. Price the conversion friction into your model, pre-stage your Turkish banking so the certificate never slows a deal, and keep the declared price honest so the certificate, the deed and your future gain all line up. Done well, the currency rule is just good deal hygiene.
