The Multi Currency add-on lets you enter a property price once and have visitors see it in their own currency. Exchange rates refresh daily without any account or API key. It also handles tax display, which is the part that most commonly catches administrators out.
Enabling the add-on adds a Currency dictionary at FW Real Estate → Dictionaries → Currency. Each entry carries a short name, a rate, and its own tax rate.
Rates refresh automatically by pulling the European Central Bank's daily reference rates — free, no account, no API key required. Refreshes are throttled to once per day and driven by the site's scheduled job. You can still type a rate by hand for any currency where you want a fixed value.
If you change the backend currency, every rate is rebased onto the new one using the rates already on record, so existing prices stay consistent rather than jumping to unexpected values.
All settings are at Configuration → Add-ons → Multi-currency.

The Tax display setting has four options:
Tax is calculated using the per-currency tax rate from the Currency dictionary. A currency with a tax rate of 0 shows no tax at all — which is exactly how you serve a VAT market and a non-VAT one from the same catalogue without maintaining separate listings.
This setting is off by default, deliberately. When enabled, it sends the visitor's IP address to a third-party lookup service (ipapi.co) to determine their country. A first-time visitor then sees their country's currency automatically, and in Let the visitor switch mode, VAT-country visitors see tax-inclusive prices. Crawlers are never looked up.
Whether that trade-off is acceptable depends on your privacy policy, not on any technical requirement. The setting is a switch precisely so the decision is yours to make.
